Malignant priapism secondary to metastatic prostate cancer: a case report and review of literature

Penile metastasis of cancers from other primary sites is a rare phenomenon that infrequently manifests as malignant priapism. We outline a case of an 84-year-old patient who presented with a 3-month history of painful priapism after radiation therapy for prostate adenocarcinoma. The patient underwent surgical penile exploration and cavernosal biopsy that revealed poorly differentiated cells suggestive of prostate cancer. Postoperative imaging demonstrated extensive regional and distal metastases. A review of the literature on penile metastases returned approximately 400 published cases, with priapism being the initial presentation in 20% to 50% of cases. Regardless of site of origin or subsequent management, most cases have shown very poor prognosis.     

Accidental finding of an anomalous spinal nerve root during lumbar-disc surgery: a case report and a review of literature

Anomalies of lumbosacral nerve roots, even though are rare, have been well documented so far in the medical literature. The early diagnosis of these anomalies may be difficult and it is crucial to develop specific methods for depicting them. Preoperative diagnosis of anomalous lumbosacral spinal nerve roots using the magnetic resonance imaging is essential to facilitate thorough surgical planning in order to avoid unnecessary complications for the patient during surgery. The operative management of these anomalies depends on the patient's neurological problems and while asymptomatic and accidentally diagnosed cases do not require treatment, patients who suffer low back or sciatic pain need surgical intervention in order to decompress nerve roots. We report a 45-years old woman presented with severe low back pain associated with left lumboischialgia. Intraoperative finding of an aberrant L5/S1 nerve root, optimal surgical therapy and different classifications are discussed together with a review of literature.

Ingestion of superwarfarin leading to coagulopathy: a case report and review of the literature

Superwarfarins are found in many pesticides, including D-con, Prufe I and II, Ramik, Talon-G, Ratak, and Contrac. Ingestion of can lead to significant morbidity and even mortality. Physicians need to consider this diagnosis in any patient presenting with coagulopathy of unclear etiology. We present a patient with superwarfarin-induced coagulopathy and review previous cases in adults in the literature. The patient is a 60-year-old man who presented to our medical center with painless hematuria. Laboratory studies revealed an elevated prothrombin time (PT) (42.5 seconds), partial thromboplastin time (PTT) (64.6 seconds), and international normalized ratio (INR) of 7. Liver-associated enzymes were normal, and complete blood cell count (CBC) showed no evidence of disseminated intravascular coagulation. Subsequent work-up included the absence of an inhibitor by mixing study and deficiencies of vitamin K-dependent coagulation factors. The patient's warfarin level was negative. A brodifacoum level was positive, confirming superwarfarin-induced coagulopathy. The patient is currently doing well with normal coagulation studies after receiving high doses of vitamin K for several weeks. The cause of his exposure to superwarfarin remains uncertain. Physicians need to be cognizant of this unusual cause of coagulopathy in adults. The appropriate diagnostic work-up and unique features of therapy are discussed.

Metastatic cervical carcinoma to the thyroid gland: a case report and review of the literature

Although metastases within the thyroid gland are rare, they are not as infrequent as generally believed. Asymptomatic breast, lung, and renal cell carcinomas may metastasize to the thyroid. When they become symptomatic, diagnosis relies upon fine needle aspiration cytology. We report the case of a squamous cell cervical cancer that presented metastatic lesions to the thyroid gland four years after the initial diagnosis. The procedures used to confirm the diagnosis, stage, and subsequently manage the patient are described. We present both a review of the necessary clinical investigation and the therapeutic options open to these patients. We conclude that patients who present swelling or palpable nodules in the thyroid side and have a history of a previous malignancy must be considered for metastatic disease.     

Malignant struma ovarii: report of a case and review of the literature

Malignant struma ovarii is a very rare disease and therefore there is neither common agreement on treatment regimens nor sufficient follow-up experience. The case of a 38-year-old woman with malignant struma ovarii is described. The patient presented with a clinically silent ovarian neoplasm discovered incidentally during investigations for metrorrhagia. The ovarian mass was resected and the tumor was found to be a teratoma. Within the teratoma a papillary thyroid carcinoma of the follicular variant was found. Subsequently, in order to make follow-up of the patient possible by thyroglobulin measurement and radioiodine whole body scintigraphy, near-total thyroidectomy was performed and the thyroid was found to be normal on histology. Whole body radioiodine scintigraphy with (131)I and ablation of the thyroid remnant by the administration of 80 mCi (131)I was performed. The patient recovered uneventfully and is now well.

An individual approach to feline diabetes care: a case report and literature review

Background

Achieving insulin independence is emerging as a realistic therapeutic goal in the management of feline diabetes mellitus.

Case presentation

The management of an 11-year-old spayed female Burmese cat presenting with diabetes mellitus after corticosteroid administration is described. Remission was achieved after the frequency of insulin administration was increased to four times a day, and supported by intensive home blood glucose monitoring and a high protein, low carbohydrate diet.

Conclusion

Owners are important collaborators in feline diabetes care and, with intensive home monitoring, more frequent insulin treatment may lead to remission without hypoglycemia. More frequent insulin injections than recommended in the literature may be necessary to achieve glycemic control and used as an alternative to a longer-acting insulin.

     

Myoepithelioma within the carpal tunnel: a case report and review of the literature

Myoepitheliomas of the extremity are rare and usually benign, while a minority display malignant features. This case demonstrates the diagnosis and management of myoepithelioma within the carpal tunnel. Clinical and radiological tumour features were evaluated. Hematoxylin and eosin stained tumour sections were examined, and immunohistochemistry was performed. Histology revealed a nodular mass of epithelioid cells in clusters within a myxoid/chondroid stroma. No mitoses were noted. Cytokeratins, neuron-specific enolase, synaptophysin, glial fibrillary acidic protein, and S100 were positive on immunohistochemistry. A literature review revealed very few prior reports of myoepithelioma in the wrist, and limited data concerning any relationship between recurrence and quality of surgical margins. In this case, wide local excision would have significantly compromised dominant hand function, and therefore a marginal excision was deemed appropriate in the context of bland histological features. Surgical margins noted in future case reports will aid clinical decision making.     

Cutaneous ciliated cyst: case report and literature review

An 18-year-old girl had a cyst excised from the left buttock in 1988. The cyst was diagnosed to be a cutaneous ciliated cyst, since histologic examination using special stains demonstrated its lining to be similar to fallopian tube epithelium. Only 20 such cases have been published to date, and this report is probably the first case in the plastic surgical literature, to the best of our knowledge.     

Clinical and diagnostic features of partially anomalous pulmonary venous connection in an adult female patient: a case report and review of the literature

A 40-year-old woman presented with dyspnoea, chest pain and fatigue. Her medical history was unremarkable. An early systolic ejection murmur was heard in the 3D left inter-costal space. Chest X-ray revealed normal cardiothoracic ratio with an anomalous vessel adjacent to the left pulmonary hilum. Echocardiography and exercise tolerance test were normal. Right heart catheterisation revealed normal pulmonary pressures with normal cardiac output. CT scan and MRI of the thorax were diagnostic for an aberrant pulmonary venous connection between the left lower lobe pulmonary vein and the left brachiocephalic vein without atrial septal defect. She was treated conservatively and remained well.     

Sclerosing variant of PEComa: report of a case and review of the literature

Tumours of perivascular epithelioid cells (PEComas) are a heterogeneous group of uncommon mesenchymal neoplasms which exhibit a peculiar immunohistochemical co-expression of muscle and melanocytic markers. PEComas occur at various visceral and soft tissue sites, generally with a benign clinical course. Nevertheless, there has been evidence of cases having an unfavourable outcome, thus prompting investigation of pathological criteria for malignancy. A sclerosing variant of PEComa, more frequently encountered in the retroperitoneum of middle-aged women, has been reported. Prognosis has generally been regarded as favourable and complete surgical excision appears to be adequate treatment. To the best of our knowledge, only two cases of sclerosing PEComa displayed high-grade malignant morphology and were associated with adverse outcome. An additional case of retroperitoneal sclerosing PEComa with a two-year follow-up and indolent behaviour is herein described. Light and electron microscopy were performed, along with immunohistochemical analysis. Further studies are needed to clarify the histogenesis and to predict the biological behaviour of this uncommon entity.
