A case of granular lymphocyte proliferative disorder with squamous cell carcinoma of penis is described.
A 77-year-old Japanese male was admitted to our hospital in March, 1989 because of ulceration of penis and lymphocytosis. He had hepatomegaly and lymphadenopathy but not splenomegaly on physical examination. The WBC count was 10800/μl with 83% of granular lymphocytes. Thrombocytopenia (32000/μl) and mild anemia were also demonstrated. Bone marrow aspirate showed hypercellular marrow with 84% of granular lymphocytes. Proliferative granular lymphocytes were CD2+ CD3+ CD4- CD8- CDw29+ and exhibited ADCC activity but not NK activity. On March 15, amputation of penis was performed. But his lymphocytosis didn't change and thrombocytopenia increased. Thus we considered his granular lymphocytosis was neoplastic rather than reactive. Our case seemed to be rare and was compared with previous reports.
