A Case of T-cell Lymphoblastic Lymphoma Involving the Skin / 대한피부과학회지

ABSTRACT

Lymphoblastic lymphoma(LBL) is non-Hodgkin's lymphoma with a high tendency of rapid progression to acute leukemia, but cutaneous infiltration is rare. Cutaneous lesions in LBL were largely red papules and nodules. We herein report a case of 24-year-old woman with T-cell LBL(TLBL) involving the skin. The lesions revealed 1~3 cm-sized, multiple confluent scaly patches on her face and back, and subsided about 4 weeks later during the period of follow-up and combination chemotherapy. Histologically there were perivascular, periadnexal and perineural infiltrates of medium-sized lymphoid cells in mid to deep dermis. The neoplastic cells had scant cytoplasm, very fine chromatin, and inconspicuous nucleoli and expressed CD5, CD45, CD45RO and TdT.
