Résumé fourni par la source

Conflict of interest: the authors declare that they have no conflicts of interest. A 44‐year‐old man presented with a 6‐month history of an asymptomatic soft swelling affecting his right superior pinna. There was no discharge or bleeding from the lesion. He had a history of excessive sun exposure. On physical examination, he was found to have a soft, fluctuant, solitary, flesh‐coloured lesion, 10 × 5 mm in size, on his superior right pinna (Fig. 1). There was no lymphadenopathy present. ... A biopsy was taken. Histological examination identified effacement of the dermis by a diffuse infiltrate of small to medium‐sized lymphoid cells, with angulated nuclear outlines and small nucleoli. There was no epidermotropism, and the cells were separated from the epidermis by a Grenz zone. There was no evidence of necrosis, or of any angiocentric or angiodestructive features. Scattered plasma cells were seen, but there were no eosinophils or histiocytes (Fig. 2a).
