[Primary cutaneous T-cell lymphoma of the penis complicated by Fournier gangrene: a case report].
OBJECTIVE
To explore the clinical presentation, pathologic characteristics, diagnosis and treatment of cutaneous T-cell lymphoma of the penis.


METHODS
A 49-year-old man presented with painful swelling and inflammation of the foreskin, failed to respond to antibiotic treatment and dorsal incision, and was instead complicated by Fournier gangrene. Then he underwent debridement and pathological examination.


RESULTS
Pathological results indicated cutaneous T-cell lymphoma of the penis. Immunohistochemistry showed CD3 and CD45 RO to be positive, but CD30, CD79a, CD20 and HMB negative. The patient was treated by interferon alpha and ultraviolet B for 2 weeks, followed by total removal of the external genitalia because of necrosis of the corpus spongiosum, which involved the scrotum and right testis on pathological examination.


CONCLUSIONS
Cutaneous T-cell lymphoma of the penis is a rare condition and easily mis diagnosed in the early phase. Definitive diagnosis depends on pathological study.
