Pigmented fungiform papillae of the tongue: An incidental finding in a patient with mycosis fungoides

A 28-year-old Hispanic man with a history of stage IA mycosis fungoides presented with "new dark spots on the tongue." He was not taking any medications and had never been prescribed minocycline. He also denied pain, pruritus, and systemic symptoms. His skin disease had been clinically stable for the past five years with home, narrowband UVB phototherapy twice a month. Physical examination of the oral cavity was significant for multiple dark-brown structures on the distal tongue. Dermoscopic evaluation showed several fungiform papillae with pigmented borders in a rose petal pattern.
