Abstract: | Localized cutaneous nontender nodules appeared on the back of a 52-year-old Japanese woman. Skin biopsy revealed atypical large T-lymphocytes infiltrating the dermis. CD30 staining was negative in tumor cells. The diagnosis was CD30-negative cutaneous large T cell lymphoma. There was no evidence of peripheral lymphadenopathy or bone marrow involvement. Six cycles of induction chemotherapy were administered and a complete clinical remission (CCR) was attained. Local irradiation was not given. As the clinical course of CD30-negative cutaneous large T cell lymphoma is recurrent and often incurable with conventional chemoradiotherapy, she received high-dose chemotherapy without total body irradiation (TBI) followed by unpurged autologous peripheral blood stem cell transplantation (APBSCT). A relapse in the skin followed 40 days after APBSCT, but tumor cells transformed into a CD30-positive anaplastic large cell lymphoma (ALCL). We question the need for TBI in conditioning and for purged stem cells for APBSCT in patients with high risk cutaneous lymphomas. |
