A 28-year-old man with a history of mycosis fungoides presented for evaluation of multiple darkbrown macules and hyperpigmented dome-shaped papules on the distal tongue. A shave biopsy of the tongue revealed melanin pigment in the basal keratinocytes and melanophages in the lamina propria, consistent with pigmented fungiform papillae of the tongue. Relevant clinical and histologic features of this diagnosis are reviewed.
