The malignant lymphoma is malignant tumor derived from B or T lymphocyte, rarely histiocyte. Generally, the disease can invade lymph node, spleen, liver, digestive system, kidney and skin. The prevalent age is between thirties and eighties.
We experienced a 74 years old man with two asymptomatic rapid growing protruding mass with centeral oozing and ulcerative lesion on the jaw for 3 months. Histologically, the tumor is composed of diffuse infilterated large tumor the cells similar
with
histiocyte morphologically throughout the dermis. In immunohistochemical stain with leukocyte common antigen, many yellowish stained atypical tumor cells were seen in the dermis. For evaluation about the origin of tumor cell, immunohistochemical
stains
with UCHL-1, L-26, CD4, CD8, CD20 were done but all negative. The patient died after 3 months in spite of 8th days of chemotherapy, probably due to brain metastasis.
