Mycosis fungoides (CTCL) associated with colorectal adenocarcinoma. A rare case of combined response to neoadjuvant therapy.

Résumé fourni par la source

Mycosis fungoides (MF) is a well-known and common form of cutaneous T-cell lymphoma (CTCL), composed of malignant proliferation of CD4+CD45Ro+helper memory T cells. In the patient with MF, the incidence of secondary malignancies is higher than general population but very few cases with both MF and colorectal adenocarcinoma have been reported. Herein we describe a case of MF occurring in a 64-year-old man and followed, five months later, by a diagnosis of colorectal adenocarcinoma. Of notice, simultaneous regression of both rectal mass and cutaneous MF manifestations was observed after administration of chemioradiation therapy prior to rectal surgery. The patient is alive and in stable clinical remission at eight years from the diagnosis. KEY WORDS: CTCL, Colorectal adenocarcinoma, Mycosis fungoides, PUVA.
