Histopathology of a skin sample taken from the lumbar region demonstrated mild acanthosis and follicular hyperkeratosis, mild lymphohistiocytic inflammatory infiltrate in the superficial dermis and melanophages (Figure 5). Histopathology from a mucosal sample showed mild to moderate regular acanthosis and lymphohistiocytic infiltrate in the superficial lamina propria with numerous melanophages (Figure 6).
