Cutaneous malignant lymphoma in an infant.
A case of cutaneous malignant lymphoma in a 7-month-old infant is described. The skin was the only apparent organ involved. Immunophenotypic studies revealed that the infiltrate was positive for B4 (CD19), J5 (CD10), and cytoplasmic mu chain, and lambda chain, but negative for B1 (CD20). The significance of these findings is discussed. We believed the tumor was of B-cell origin. The reported cases of cutaneous malignant lymphoma in infancy are briefly reviewed.
