BACKGROUND: Idiopathic granulomatous mastitis (IGM) is a benign, inflammatory breast disease of unknown etiology. Although it is rare, it frequently presents in a manner similar to that of breast carcinoma. CASE: A 41-year-old female developed unilateral idiopathic granulomatous mastitis, diagnosed by fine needle aspiration cytology. The clinical presentation and mammographic findings were suspicious for carcinoma. Fine needle aspiration cytology showed granulomatous inflammation. Histopathologic examination revealed a noncaseating, granulomatous lesion. Further clinical, radiologic and laboratory investigations disclosed no etiology. Therefore, we considered the case to be idiopathic granulomatous mastitis. CONCLUSION: Cytologically it may be difficult to distinguish IGM from carcinoma of the breast. Typical cytologic findings of the lesion are helpful to rule out cancer. In the differential diagnosis, all known causes of granulomatous changes have to be excluded before a diagnosis of idiopathic granulomatous mastitis is made. 相似文献

Mycetoma (madura foot, maduromycosis) is present worldwide but more so in the tropics. We report a case of actinomycetoma diagnosed by fine needle aspiration using cell smears. The authors believe it to be the first case so diagnosed. Definitive diagnosis of the etiologic agent is made by culture, leading to a delay in institution of treatment. The authors advocate the use of fine needle aspiration for rapid diagnosis, thus instigating further workup and treatment. 相似文献

Nonaspiration fine needle cytology. Application of a new technique to nodular thyroid disease 总被引:2,自引:0,他引:2
The basic principle underlying fine needle aspiration (FNA) is the aspiration of cellular material from target masses, often utilizing fairly high suction pressures. The procedure requires a needle and a syringe, advisedly held in a syringe holder, enabling single-handed suction to be exercised. Mastery of the technique is variable, with few operators acquiring consistent skill. A new technique, pioneered in France but essentially unpublicized, eliminates active aspiration, replacing it by the principle of capillary suction of fluid or semifluid material into a thin channel (a fine needle). This nonaspiration sampling method was tested in a consecutive series of 50 solid thyroid nodules. Simultaneously performed conventional FNAs served as controls. Cell samples were cytologically assessed as unsuitable, diagnostic/adequate or diagnostic/superior, without knowledge of the sampling method employed. Diagnostically superior specimens were obtained significantly more frequently by the nonaspiration technique in 36 benign lesions and 13 neoplasms. The method of nonaspiration fine needle cytology ("cytopuncture") is described and illustrated, and the implications for its use in other sites are discussed. 相似文献

BACKGROUND: Primary pulmonary leiomyosarcoma is a rare but important entity. We report a case diagnosed by fine needle aspiration cytology. CASE: A 73-year-old male presented with an asymptomatic, right, pulmonary, subpleural nodule detected by computed tomography during follow-up for chronic obstructive pulmonary disease. Fine needle aspiration cytology showed cellular smears with numerous single or loosely cohesive groups of spindle-shaped to round cells. The tumor cell nuclei were blunt ended (cigar shaped), with fine to fine-granular chromatin, prominent nucleoli and an irregular nuclear rim. The tumor cells were positive for desmin and negative for cytokeratin and S-100 protein by immunocytochemistry. Right upper lobectomy with lymph node dissection was performed. Pathologic diagnosis after microscopic, immunohistochemical and electron microscopic studies was leiomyosarcoma. CONCLUSION: To our knowledge, this is the first reported case of primary pulmonary leiomyosarcoma arising in the subpleural region diagnosed by fine needle aspiration cytology. Immunocytochemistry was useful in establishing the diagnosis in this case. 相似文献

Thyroid large needle aspiration biopsy is disregarded because it is thought to be associated with pain. This is in contrast with our 32 years long experience. We surveyed reports of pain in patients examined with fine needle aspiration biopsy (78, 87.2% women, mean age 59 years) or FNAB+large needle aspiration biopsy (48, 87.5% women, mean age 60 years). Each patient was questioned regarding a) no unpleasant sensation (score “0”); b) unpleasant sensation (“1”); c) mild pain (no analgesic used; “2”); or d) pain (analgesic used; “3”). The mean size of the needle used was for FNAB 22.3±0.7 or 20.8±1 gauge in the fine needle aspiration or fine needle aspiration plus large needle aspiration biopsy group, respectively (p<.0001). The number of percutaneous punctures was higher in the fine needle aspiration plus large needle aspiration biopsy group. However, the pain score in the fine needle aspiration biopsy or fine needle aspiration biopsy plus large needle aspiration biopsy group was not significantly different. Large needle aspiration biopsy after fine needle aspiration biopsy does not add any discomfort or pain and therefore in light of the demonstrable benefits, should be included in clinical algorithms for the evaluation of thyroid nodules. 相似文献

This paper reviews the history, technique, applications, advantages, disadvantages and complications of percutaneous needle aspiration biopsy. This technique, particularly when performed with a time needle (21-gauge or less), is a relatively painless, inexpensive and safe method of obtaining a pathologic diagnosis, and it can often be carried out at the bedside or in the outpatient department. It complements other methods and may obviate, but never precludes, subsequent excisional biopsy. Its advantages are insufficiently recognized. Considerable expertise of the cytopathologist and close cooperation with the clinician are necessary for consistent results. 相似文献

Fine needle aspiration is a quick, minimally invasive and cost-effective technique for the diagnosis of granulomatous disease. Cytological diagnosis can often be specific, with the help of special stains and microbiological culture of aspirated material, particularly in the case of tuberculosis, the most common infective granulomatous disease in this country. At a fine needle aspiration clinic many cases of granulomatous disease, some from unusual sites, have been diagnosed and the use of more invasive investigations has been avoided. The problems involved in cytological diagnosis are discussed using seven cases as examples. 相似文献

The cytologic findings from fine needle aspiration of a left shoulder mass are described for a woman who had undergone renal transplantation and on whom an orthopedic consultation suggested the clinical possibility of a soft tissue sarcoma. The aspirate samples from multiple sites in the mass showed several multinucleate, osteoclast-type giant cells, spindly or fibrillary cells with ovoid nuclei and a significant amount of granular calcium. The needle aspiration cytodiagnosis was of critical importance since it saved the patient from invasive surgical intervention. This case emphasizes the role of needle aspiration cytology in providing a rapid cytodiagnosis of osteitis fibrosa cystica with a minimally invasive method. 相似文献

OBJECTIVE--To audit the accuracy and impact on the frequency of operation of fine needle aspiration cytology of isolated thyroid swellings. DESIGN--Prospective analysis over six years of cytological predictions compared with histological findings. SETTING--Thyroid clinic serving the Grampian region. PATIENTS--395 Consecutive patients presenting with an isolated thyroid swelling, 307 of whom underwent surgical excision. Analysis was confined to a subgroup of 283 patients with satisfactory aspirates who were operated on. RESULTS--The positive predictive value of aspiration cytology for detecting malignant disease was 100% and the sensitivity 83%. The sensitivity for the detection of neoplasia (frank malignancy together with follicular adenomas) was 76%. The specificity was 58% and the overall accuracy 69%. Recalculation of data in previous papers with strict criteria showed the accuracy of aspiration cytology to be variable and lower than is widely accepted. Since the introduction of aspiration cytology 21% fewer operations for isolated thyroid swellings have been performed. CONCLUSIONS--As a basis of selection for surgical excision of isolated thyroid swellings according to prediction of neoplasia fine needle aspiration cytology is less reliable than is widely accepted. It is an adjunct to management rather than a definitive test, and negative cytological results do not exclude neoplastic disease. Further study should take account of the implications of repeated clinic attendances for review and aspiration as these may culminate in delayed surgical treatment. 相似文献

Primary papillary serous carcinoma of the peritoneum: report of a case with diagnosis by fine needle aspiration and immunocytochemistry 总被引:1,自引:0,他引:1

BACKGROUND: Primary papillary serous carcinoma (PPSC) of the peritoneum is a rare neoplasm, histologically indistinguishable from papillary serous carcinoma of the ovary, which diffusely involves the peritoneum but spares or minimally invades the ovaries. To the best of our knowledge, the preoperative and the fine needle aspiration diagnosis of this disorder have not been reported before. CASE: A woman developed an extensive peritoneal neoplasm 4 years after hysterectomy and bilateral salpingo-oophorectomy for benign disease. Fine needle aspiration of the tumor was performed, and the cytologic and immunocytochemical findings were consistent with papillary serous carcinoma. A diagnosis of PPSC of the peritoneum was rendered because review of all slides from previous surgical specimens showed no evidence of carcinoma and no other primary tumors were found elsewhere. CONCLUSION: Fine needle aspiration cytology coupled with immunocytochemical and clinical data allows an unequivocal preoperative diagnosis of papillary serous carcinoma (primary peritoneal or with an ovarian origin). The sole limitation to establish a primary peritoneal origin before surgery is the requirement to histologically study the ovaries. Based on this fact, the preoperative fine needle aspiration cytology diagnosis of PSCP should be restricted to oophorectomized patients. 相似文献

BACKGROUND: Clear cell carcinoma arising in a cesarean section scar is an extremely rare disease. To the best of our knowledge, there is no published report on the aspiration cytology. CASE: A 56-year-old woman presented with a mass in a cesarean section scar. Initially an abdominal desmoid was considered, but the features of fine needle aspiration (FNA) cytology suggested an adenocarcinoma. The resected tumor was histologically composed of clear cell carcinoma showing cystic, solid and papillary patterns. CONCLUSION: FNA cytology of masses arising in a surgical scar can be a useful tool in obtaining an accurate pathologic diagnosis of a malignant neoplasm. 相似文献

OBJECTIVE: To study the "gray zone" in breast fine needle aspiration cytology in which an unequivocal diagnosis cannot be reached with fine needle aspiration cytology findings. STUDY DESIGN: This study compared cytology and histopathology of 72 breast lesions in which an initial cytologic diagnosis of atypia was given. RESULTS: There were 36 benign (50%) and 36 malignant (50%) histologic biopsy cases in the cytologic atypia group. Anisonucleosis, chromatin and nuclear membrane irregularity, and presence of myoepithelial cells were significantly different in benign and malignant cases. CONCLUSION: The gray zone in breast fine needle aspiration cytology is a broad spectrum that changes from proliferative fibrocystic disease to sclerosing adenosis to malignancy. Diagnosing gray zone pathology as atypical in fine needle aspiration cytology causes no delay in treatment as excisional biopsy is recommended for all equivocal cases. 相似文献

BACKGROUND: Extraskeletal myxoid chondrosarcoma is a rare soft tissue tumor of the extremities. Since it usually lacks obvious chondroid differentiation on light microscopy, it needs to be distinguished from other myxoid soft tissue sarcomas. CASE REPORT: The diagnosis of extraskeletal myxoid chondrosarcoma was made on fine needle aspiration in a patient with a swelling in the right calf. Cellular myxoid fragments having round to oval cells with grooved nuclei arranged in a cordlike pattern suggested chondroid differentiation. The diagnosis was confirmed by histopathology. CONCLUSION: Fine needle aspiration cytology can be diagnostic of extraskeletal myxoid chondrosarcoma even in the absence of obvious chondroid differentiation. 相似文献

A 55-year-old male with end-stage renal disease on hemodialysis presented with neck pain of 1 year's duration. A computed tomography (CT) scan was performed as part of his workup, and a posterior cervical neck mass was detected. CT-guided fine needle aspiration was performed with an immediate cytologic interpretation of tumoral calcinosis. On air-dried Diff-Quik and alcohol-fixed Papanicolaou-stained smears, the specimen demonstrated coarse-to-fine calcific debris. A final diagnosis of tumoral calcinosis was rendered. A literature search revealed that this diagnosis is rarely made by touch imprint cytology of core needle biopsy and/or needle aspiration cytology, although it can be a relatively easy and straightforward diagnosis. 相似文献

A case of sarcoidosis presenting as multiple pulmonary nodules and investigated by transthoracic fine needle aspiration biopsy is presented. Cohesive clusters of epithelial cells as well as multinucleated giant cells were observed. Special stains performed on the cell-block preparation were useful in ruling out an infectious etiology. The case demonstrates the value of fine needle aspiration biopsy in the investigation of pulmonary parenchymal disease and illustrates the cytologic findings in this unusual presentation of sarcoidosis. 相似文献

OBJECTIVE--To assess the individual and combined diagnostic accuracy of clinical examination, mammography, and fine needle aspiration biopsy in young women with breast cancer. DESIGN--Analysis based on case notes of patients presenting with breast cancer during 1971-89. SETTING--A combined breast clinic. PATIENTS--Consecutive series of 81 women aged less than 36 with histologically proved breast cancer presenting with a discrete mass over 19 years. MAIN OUTCOME MEASURES--Results of clinical examination, xeromammography or conventional mammography, fine needle aspiration biopsy, and examination of tissue removed by surgery. RESULTS--The clinical diagnosis was correct in 47 women and radiography in 35. Fine needle aspiration biopsy was correct in 47 of the 63 women in whom it was successfully performed. Fine needle aspiration was significantly more accurate than mammography (78% v 45%, p less than 0.01). Ten (16%) patients had negative results on clinical examination, mammography, and fine needle aspiration. CONCLUSION--Mammography alone seems inadequately sensitive to detect breast cancer in young patients. When all investigations give negative results excision biopsy is the only way of obtaining a definitive diagnosis. 相似文献

BACKGROUND: Hydatid disease is caused by Echinococcus granulosus, endemic in cattle and sheep-raising regions of the world such as Central Europe, South America, Australia, New Zealand and South Africa. Although hydatid disease is more common in liver and lung, it also affects brain, kidney, spleen and muscle. We present a case of intraabdominal hydatid cyst, diagnosed by fine needle aspiration cytology, producing an indentation of the liver, which is uncommon. CASE: A male patient presented with right side abdominal pain. On ultrasonography an intraabdominal solid mass (right hypochondrial) was revealed, and subsequently FNA was done. Smears were diagnostic of hydatid cyst. CONCLUSION: FNAC is a sensitive and rapid technique in diagnosis of hydatid cysts. The present case is unusual, owing to its presentation as a solid abdominal mass seeding over the liver and mimicking malignancy radiologically. 相似文献

Diagnosis of solid breast masses by needle aspiration with cytological examination of the aspirate has been practiced for some time in several centers in this country and abroad. It has been proposed as an alternative to the conventional excisional biopsy for the diagnosis of carcinoma of the breast.At the same time, simple needle aspiration of benign cysts as an office procedure has gained new favor as a means of proving the presence of benign disease at the first office visit and thus avoiding the loss of time, and the expense and worry of surgical excision in a hospital. From a review of the reliability and practical usefulness of both methods, it is concluded that aspiration biopsy for the diagnosis of carcinoma is less reliable than conventional excisional biopsy and offers very little practical advantage.Simple aspiration of cysts, on the other hand, appears to offer a true saving of time, expense and worry, and to be a reliable method, if used properly. 相似文献

A primary carcinoid breast tumor was evaluated by fine needle aspiration cytology in an 87-year-old female. The subsequent operative material contained a tumor with the typical histopathologic features of carcinoid tumors in other sites; thorough evaluation of the patient did not reveal carcinoid lesions elsewhere in the body. The tumor contained argyrophil-positive cytoplasmic granules on light microscopy. The cytomorphology of this tumor contains features helpful in identifying it on aspiration cytology material. The differential diagnosis with fine needle aspiration cytology of other breast tumors is discussed. 相似文献

BACKGROUND: Cryptococcosis can be a life-threatening mycosis in immunocompromised patients. However, it has a somewhat better prognosis in immunocompetent hosts. AIDS has led to an increase in the incidence of the disease. Clinically, the lesions can be confused easily with malignancy. CASE: A 25-year-old, asymptomatic male presented for a routine health check-up. The chest radiograph showed a subpleural left apical area of consolidation, suspicious for either a neoplasm or infection. Fine needle aspiration cytology (FNAC) revealed a granulomatous lesion with refractile yeast forms of Cryptococcus, both within the multinucleate giant cells and extracellularly. This was subsequently confirmed by culture and histology. CONCLUSION: The cytomorphology of cryptococcosis is characteristic, and FNAC is a useful modality for diagnosing the infection in asymptomatic patients but needs a high index of suspicion, especially in nonimmunocompromised patients. 相似文献
