| Summary: | Tinea nigra is a superficial infection caused by dematiaceous fungi. The clinical skin lesion is characterized by well-circumscribed brown–black macule patches on the palms and soles. In Asia, such pigmentation on these areas can be suggestive of acral lentiginous melanoma, which cause morbidity and mortality. Here, we report a case of a young patient with solitary black macule on the left palm for a year. Potassium hydroxide test was positive for pigmented short hyphae. The lesion subsided following topical antifungal treatment without recurrence. This report aims to provide insights into diagnosis of patients with pigmentations on acral areas.
