Abstract
Tinea nigra is a superficial fungal infection usually caused by Hortaea werneckii (H. werneckii). We report a special case of tinea nigra in an immunocompetent child who developed a unilateral, rapidly growing pigmented lesion on her palm. Interestingly, Curvularia lunata (C. lunata) was isolated from the lesion scrapes and was identified by both morphological features and molecular biology methods. The lesion was completely cleared by topical naftifine hydrochloride and ketoconazole cream. We present-to the best of our knowledge-the first case of tinea nigra where the causative pathogen was identified as C. lunata. We therefore provide a brief literature review of previously reported cases of tinea nigra to broaden the knowledge of the potential causative pathogens. The etiology, demography, clinical features, diagnostic methods, and treatment of the reviewed cases are summarized and analyzed.

Abstract
Superficial mycoses are fungal infections restricted to the stratum corneum and
to the hair shafts, with no penetration in the epidermis; they are: white
piedra, black piedra, tinea versicolor, and tinea nigra. This study presents
images of mycological tests performed in the laboratory, as well as exams
performed at the authors office, in order to improve the dermatologist's
knowledge about the diagnosis of these dermatoses, which are common in many
countries.

Abstract
Tinea nigra is a superficial mycosis whose diagnosis is confirmed by isolating the infectious agent Hortae werneckii through mycological examinations. In vivo reflectance confocal microscopy, initially used in melanocytic dermatosis, has been used with skin infectious diseases to identify the parasite at the cellular level. We report, for the first time in the scientific literature, the use of reflectance confocal microscopy in a case of tinea nigra and compare its findings to dermoscopy and mycological examination results.
