[Pigmented nodular tenosynovitis. A misdiagnosed etiology of isolated tumefaction of fingers or toes].

BACKGROUND: Pigmented nodular tenosynovitis (more commonly called giant cell tumor) is a benign tumor of synovial joint or tendon sheaths. CASE REPORT: A 17-year-old girl had a tumefaction of the first toe. The mass was firm and painless and had been present for one year. Radiological studies revealed a cystic area of the first phalanx. Magnetic resonance imaging demonstrated a poorly vascularized tissular lesion. Surgical excision of the tumor was performed. Macroscopic and histologic findings confirmed the diagnosis of pigmented nodular tenosynovitis. DISCUSSION: Clinical and radiological aspects of nodular tenosynovitis are characteristic. This diagnosis should be made by dermatologists. Eighty percent of cases occur in fingers and more rarely in toes. Patients are usually females (60 p. 100). A subcutaneous mass is the most common presenting sign whereas pain or joint swelling are rare. Optimal treatment is surgical resection. The only risk is recurrence (20 p. 100).

Tinea capitis in adults: misdiagnosis or reappearance?

BACKGROUND: According to the literature, tinea capitis in adults is supposed to be rare; we have recently observed a significant increase in cases. METHODS: Epidemiological, clinical and mycological features were studied in all adult tinea capitis diagnosed over 1 year in our department. RESULTS: Eight cases were observed: 75% of them were women, 50% never traveled and 62.5% had an underlying immunosuppressive disease. Scalp scaling and alopecia were the most frequent clinical features. A zoophilic dermatophyte was recovered in 50% of cases. CONCLUSION: These cases represent 11% of all tinea capitis observed in the same period of time (higher than the 3-5% observed in the literature). Secretion of sebum and colonization by Pityrosporon orbiculare are supported to protect the scalp against dermatophytic invasion after puberty, but an immune defect may also facilitate hair invasion. The erroneous notion of the disease being uncommon and the frequent atypical clinical presentation require a high degree of clinical suspicion.

Unusual Microsporum canis infections in adult HIV patients.

Tinea capitis in men, even if infected with HIV, is infrequent. Microsporum species nail infections are extremely rare. In most cases Microsporum canis infection is usually easy to treat with antifungal agents. We describe two HIV-infected men with an unusual M. canis infection. Both patients had tinea capitis, presenting as alopecia in one and scaling of the scalp in the other. One patient also had tinea unguium caused by M. canis. Ketoconazole was ineffective in both patients; terbinafine was tried in one patient without benefit; itraconazole was effective in both, but treatment took many months and only one patient was cured.

[Methotrexate and psoriasis].

Methotrexate is effective in the treatment of severe psoriasis. If recommended guidelines are strictly followed the drug, administered in low doses, is not dangerous. The main adverse effect is cumulative hepatotoxicity. Hematologic toxicity occurs especially if other medications are associated.
