[Adult T-cell lymphoma/leukemia: a very rare disease in Europe]

A 45-year-old man was admitted with generalized itchy papules. He was originally from the Carribean island of Grenada. The disease had started two years before and was diagnosed as lupus erythematosus, polymorphic light eruption and atopic eczema. Physical examination showed skin-colored papules all over the integument, sebostasis and enlarged supraclavicular and inguinal lymph nodes.

Lymphocyte count was elevated with 58% as well as LDH (322 U/l) and gamma GT (133 U/l). In a blood smear characteristic pleomorphic lymphoid cells (flower cells) could be obtained. Histopathologic evaluation demonstrated a subepidermally located infiltrate of pleomorphic lymphocytes with epidermal involvement. HTLV-I/II serology (ELISA-screening test) was positive. Polymerase chain reaction analysis revealed HTLV-specific sequences.

Diagnosis of adult T-cell lymphoma/leukemia was obtained. Treatment consisted of interferon alpha 2b and zidovudine which resulted in a rapid response. However, as a result of an increased loss of weight (12 kg) this therapy was stopped. Two weeks later generalized lymphadenopathy and disseminated skin lesions were observed. Chemotherapy (CHOP-scheme) was initiated. The patient deceased with signs of an acute leukemia after a short period.

Adult T-cell lymphoma/leukemia is a rare disease in Europe. However, in patients with skin rashes, and lymphadenopathy, which are originally from HTLV-I endemic areas, adult T-cell lymphoma/leukemia should be considered.
