Résumé
A case of cutaneous lesions on the left lower leg caused by Curvularia species in an 80-year-old immunocompetent woman is described in this report. The etiological agent was identified as Curvularia species based on its colonial and microscopic morphology in pure tissue culture. The lesions healed after a 9-week regimen of oral itraconazole and topical lanoconazole.

BACKGROUND: Hair and nails are known to be related in their origin and anatomical structures, and they are similar in their structure and growth pattern. Nail changes were first reported to be associated with alopecia areata (AA) in 1898. One of the clinical features of AA is nail abnormalities, and these are found in 7% to 66% of patients with AA. OBJECTIVE: We evaluated the frequency, clinical presentation, and associated factors of nail changes in patients with AA. METHODS: A prospective study of 121 patients with AA was performed. The diagnosis of AA was made on clinical grounds. Patients' medical history was obtained, and thorough examinations were performed. Patients with other diseases associated with nail changes were all excluded from the study. The association between the clinical features of patients with AA and the prevalence of nail changes was evaluated using logistic regression analysis. RESULTS: Of the 121 patients, 40 (33%) presented with nail changes. In multivariable analysis, younger age (compared with ≥19 years old; odds ratio [OR] 3.663, 95% confidence interval [CI] 1.094~12.346, p=0.035), chronicity (disease duration ≥2 years; OR 2.852, 95% CI 1.230~6.613, p=0.015), and disease subtype (alopecia totalis and alopecia universalis); OR 5.846, 95% CI 1.078~31.717, p=0.041) were identified as independent factors associated with nail changes in patients with AA. Among the nail abnormalities identified, nail pitting was the most common, observed in 20 patients (50%). Trachyonychia was present in 7 patients (16%), leukonychia in 7 (16%), and Beau line in 5 (11%). Other changes were also observed, including melanonychia, onycholysis, absence of lunula, and onychoschizia. CONCLUSION: In conclusion, younger age, chronicity, and disease subtype (alopecia totalis and alopecia universalis) were shown to be independent relevant indicators of the nail changes in patients with AA.

We report a case of Majocchi's granuloma in a 71-year-old immunocompetent male patient, who presented with a 6-month history of mass with multiple erythematous nodules and indurated plaques with scale on the left cheek. Even though the lesion strongly suggested cutaneous tumor, the histopathologic findings were consistent with the Majocchi's granuloma, showing numerous hyphae, perifolliculitis and granulomatous inflammation with central abscess formation in the dermis. Trichophyton rubrum was isolated from the biopsy specimen fungus culture. The cutaneous lesion was treated with oral administration of itraconazole (200 mg/day) and topical lanoconazole cream for 4 weeks, and successfully treated.
