Abstract
- Lymphoblastic lymphoma is classified as non-Hodgkin's lymphoma with high tendency of rapid progression to acute leukemia. Cutaneous involvement of this condition is rare. The clinical feature of skin lesions usually present single or multiple papular or nodular lesions preferentially located on the head and neck. Herein, we report a case of an 18-year-old man presenting skin involvement of T cell lymphoblastic lymphoma. The lesions manifested as asymptomatic, multiple, round, slightly pinkish nodules on the scalp and trunk. Histological examination showed dense, diffuse infiltration of medium-sized lymphoid cells throughout the entire dermis. The neoplastic cells had scant cytoplasm and nuclei characterized as round or slightly irregular with expression of CD3, CD5, CD45, TdT and Ki-67.
