Bilateral Tinea Nigra Plantaris with Good Response to Isoconazole Cream: A Case Report.

Abstract

Tinea nigra is a superficial fungal infection caused by Hortaea werneckii. It typically affects young individuals as an asymptomatic unilateral macule, from light brown to black on the palms and soles, mainly in tropical and subtropical regions. In 1997, Gupta et al. [Br J Dermatol 1997;137:483-484] described the dermoscopic characteristics of tinea nigra. Topical antifungals with or without keratolytic agents can be used for the treatment. The authors report a case of a 47-year-old man with asymptomatic light brown macules bilaterally on the plantar regions. Dermoscopic examination revealed brownish spicules consistent with the pattern described in the literature. Treatment with isoconazole cream was effective with complete resolution.
