Follicular Mucinosis Associated with Adult T-Cell Leukemia-Lymphoma.

BACKGROUND AND PURPOSE: Follicular mucinosis is characterized by deposits of mucin in the sebaceous gland and outer root sheath of hair follicles. The diagnosis may occur without another cutaneous disease ("idiopathic" follicular mucinosis) or in association with hematologic malignancies, most often cutaneous T-cell lymphoma, and other skin conditions.

PATIENT: We present a case of follicular mucinosis occurring in an African male with adult T-cell leukemia-lymphoma.

RESULTS AND INTERPRETATION: Four cases of follicular mucinosis in the setting of adult T-cell leukemia-lymphoma have been reported previously in the literature. It is important to consider that not all lymphoma related follicular mucinosis is associated with cutaneous T-cell lymphoma.
