皮肤型孢子丝菌病首选口服抗真菌药物治疗,如碘化钾、伊曲康唑、特比萘芬和氟康唑等[1].由于个体差异及疾病情况的复杂性,患者对每种抗真菌药物治疗的反应不同,最近我们应用不同的方法治愈了4例皮肤型孢子丝菌病患者,报道如下.1临床资料1.1病例1患者男,68岁,北京市延庆县农民.因右侧面部皮损8个月于2008年12月8日就诊.8个月前患者右侧面部出现米粒大小皮损,之后皮损破溃、增多,伴疼痛.否认外伤史.皮肤科情况:右面颊部可见8个1 ~1.5 cm大小皮损,基底红肿,其上有厚的结痂,无脓液渗出,可触及多数皮下结节(见图1a).皮损痂屑KOH湿片真菌镜检阴性,皮损组织真菌培养为申克孢子丝菌.皮损组织病理显示表皮角化不全,有脓痂,表皮呈假上皮瘤样增生;真皮全层弥漫淋巴细胞、组织细胞、多核巨细胞、浆细胞、嗜中性粒细胞浸润,伴少许嗜酸粒细胞;PAS染色未见真菌成分.诊断:皮肤淋巴管型孢子丝菌病. 相似文献

目的探讨皮肤播散型孢子丝菌病发生的病因、临床特点、诊断及鉴别诊断,以提高对该病的认识,避免误诊、误治。方法对1例以声嘶为首发表现的皮肤播散型孢子丝菌病的临床资料、组织病理、真菌培养结果进行分析,并进行相关文献复习。结果患者以声嘶为首发表现,3个月后出现全身散在皮下结节。结节逐渐增多,部分破溃伴脓血。咽部组织病理示鳞状上皮黏膜急慢性炎伴上皮乳头状增生,可见多核巨细胞,抗酸染色未查出阳性菌。皮损处脓液真菌镜检及培养阴性。病理符合感染性肉芽肿。组织真菌培养见孢子丝菌生长。诊断为皮肤播散型孢子丝菌病。结论皮肤播散型孢子丝菌病在免疫正常人群发病时容易导致误诊误治;皮损表面脓液真菌镜检及培养阳性率低。病变组织真菌培养有利于得到阳性结果,早日明确诊断和治疗。 相似文献

感染性肉芽肿是一类慢性增生性炎症。放线菌和诺卡菌所致感染性肉芽肿实属少见,但两者临床症状、体征相似,易误诊或漏诊。本文报道1例放线菌与1例诺卡菌所致皮肤感染性肉芽肿,通过皮肤组织病理学检查、细菌培养、生化鉴定及细菌分子生物学检测,最终明确诊断。进一步分析2种感染的病因学、流行病学、临床表现、诊断和鉴别诊断及治疗,并结合最新研究进展,可帮助临床医师更好地认识放线菌属细菌所致感染性皮肤肉芽肿,以便于及时诊断、及时治疗。这2种感染有很多相似之处,也有各自特点,需临床医师求同存异,仔细鉴别;还需与其他感染性肉芽肿如皮肤结核、孢子丝菌病或着色芽生菌病等鉴别诊断。 相似文献

Background
There have been several recent changes in the taxonomy of Sporothrix schenckii as well as new observations regarding the clinical aspects of sporotrichosis. In this study, we determined the identification of the Sporothrix species associated with both classic and unusual clinical aspects of sporotrichosis observed in the endemic area of sporotrichosis in Rio de Janeiro, Brazil.Methodology/Principal Findings
To verify whether S. brasiliensis is associated with clinical manifestations of sporotrichosis, a cross-sectional study was performed in which Sporothrix isolates from 50 patients with different clinical manifestations were analyzed and their isolates were studied by phenotypic and genotypic methods. Data from these patients revealed a distinct clinical picture and therapeutic response in infections caused by Sporothrix brasiliensis (n = 45) compared to patients with S. schenckii sensu stricto (n = 5). S. brasiliensis was associated with disseminated cutaneous infection without underlying disease, hypersensitivity reactions, and mucosal infection, whereas patients with S. schenckii presented with less severe and more often localized disease, similar to the majority of previously described sporotrichosis cases. Interestingly, S. brasiliensis-infected patients overall required shorter durations of itraconazole (median 16 weeks) compared to the individuals with S. schenckii (median 24 weeks).Conclusions/Significance
These findings suggest that Sporothrix species are linked to different clinical manifestations of sporotrichosis and that S. brasiliensis is effectively treated with oral itraconazole. 相似文献13.

BackgroundSporotrichosis is a subacute and chronic infection caused by Sporothrix schenckii, which affects humans and other mammals. Clinical and epidemiological information in Colombia is scarce.ObjectiveTo describe clinical and socio-demographic findings and diagnostic tests in patients with sporotrichosis from 1996 to 2005 in a national reference center in Colombia, and to determine the institutional prevalence from 2002 to 2005.Material and methodsThis was a prevalence study, including patients with clinical diagnosis of sporotrichosis and at least one of the following criteria: positive culture with S. schenckii, pathologic diagnosis suggestive of sporotrichosis, or response to treatment with potassium iodide.ResultsSixty cases were included, 67% were male, and 25% of them were farmers. The most affected anatomical areas were the forearms and hands (32.5% and 22.8% respectively). Most cases came from the Cundinamarca and Boyacá areas. The cases presented as fixed cutaneous sporotrichosis and lymphangitic sporotrichosis. Differential diagnoses with: leishmaniasis and chromoblastomycosis were performed in most of the cases. All patients were treated with potassium iodide. The prevalence for our center from 2002 to 2005 was 8 cases per 100,000 patients.ConclusionsThe characteristics of our patients are similar to those described in other populations, with some differences. The culture continues to be the gold standard for diagnosis purposes. Potassium iodide is the treatment of choice in our center. 相似文献

BackgroundThe gold standard for the sporotrichosis diagnosis is culture; however, serologic approaches have been recently implemented to aid in the sporotrichosis diagnosis. Nevertheless, the clinical consequences of the introduction of serologic tests are poorly addressed.AimsTo correlate the results of culture and serology of patients with suspected sporotrichosis.MethodsA retrospective study of 198 patients with suspected sporotrichosis was conducted. Information about culture isolation of Sporothrix from clinical samples and antibody detection by an enzyme-linked immunosorbent assay (ELISA) were obtained from the medical records of the patients.ResultsPositive culture and antibody detection was observed in the samples of 84 patients (42.4%). Forty-one samples (20.7%) showed negative results with both techniques and divergent results were obtained in the samples of 73 patients (36.9%). False negative results in the ELISA were observed with 23 patients (31.5%), 78.3% of them with less than 30 days of infection (p = 0.0045). Among the initial false positive ELISA in the sera of 50 patients, four samples in culture yielded the growth of Sporothrix, and 27 improved with itraconazole. At the end of follow-up, a diagnosis of proven or probable sporotrichosis was established in 139 patients, and possible sporotrichosis in 11 patients. The treatment of the patients with probable sporotrichosis with antifungal drugs resulted in clinical cure for these individuals.ConclusionsThese two techniques are complementary in the diagnosis of sporotrichosis, making diagnosis and clinical decision more precise. 相似文献

Sporotrichosis associated with exposure to domestic cats is hyperendemic in Rio de
Janeiro, Brazil. A review of the clinical records at our institute revealed four
patients with clinical signs of dacryocystitis and a positive conjunctival culture
for Sporothrix who were diagnosed with Sporothrix
dacryocystitis. Three patients were children (< 13 years of age) and one patient
was an adult. Two patients reported contact with a cat that had sporotrichosis.
Dacryocystitis was associated with nodular, ulcerated lesions on the face of one
patient and with granulomatous conjunctivitis in two patients; however, this
condition manifested as an isolated disease in another patient. All of the patients
were cured of the fungal infections, but three patients had chronic dacryocystitis
and one patient developed a cutaneous fistula. Sporotrichosis is usually a benign
disease, but may cause severe complications when the eye and the adnexa are affected.
Physicians, especially ophthalmologists in endemic areas, should be aware of the
ophthalmological manifestations and complications of sporotrichosis. 相似文献

The tropical verrucous syndrome includes infectious, chronic, and granulomatous skin conditions appearing with plaques, nodules, or ulcers with a warty surface which gives name to the syndrome. It includes forms of chromoblastomycosis, sporotrichosis, paracoccidioidomycosis, lobomycosis, leishmaniasis, and tuberculosis verrucosa cutis with ample distribution in tropical and subtropical areas. The diagnoses may be difficult and confused among them, especially between sporotrichosis and leishmaniasis.Clinical, epidemiologic, intradermal reactions, direct smears, skin biopsies, cultures, immunofluorescence, and PCR are used to differentiate them, although several of these methods are not commonly used.We present an 18-year-old man with extensive verrucous plaques in one knee interpreted by clinic, epidemiology, and biopsy as verrucous cutaneous leishmaniasis. He was treated with Glucantime® for 20 days without improvement. A new biopsy was made that was also interpreted as cutaneous leishmaniasis. The revision of both biopsies showed inflammation with abscessed granulomas and asteroid sporotrichotic bodies at the center of the granulomas that led to the diagnosis of sporotrichosis later confirmed by the fungus culture. The patient responded to the treatment with itraconazole. As clinical and epidemiological findings of leishmaniasis and sporotrichosis can be similar, skin biopsy and other paraclinical studies are necessary to establish a proper diagnosis. The asteroid sporotrichotic body is pathognomonic of this mycosis. We review here the essential concepts of leishmaniasis and sporotrichosis and the criteria to differentiate them. 相似文献
