Syringotropic mycosis fungoides responding well to VELP chemotherapy: A case report.

Mycosis fungoides (MF), a low-malignant lymphoproliferative disorder, is the most common type of cutaneous T-cell lymphoma. The current study reported a case of syringotropic MF, a rare variant of MF, which presented with reactive B cell proliferation, lymphoid follicle formation, hair loss and lymphadenopathy. The clinical manifestations of the patient were MF-like lumps. Immunohistochemical staining of AE1/AE3 showed that there were abundant infiltrated lymphocytes surrounding the syringocystadenoma. In addition, the direction of the lymphocyte arrangement was consistent with the meandering direction of syringocystadenoma. The patient did not respond to 1-month narrowband (311-nm) ultraviolet therapy; however, a good response was obtained subsequent to one cycle of chemotherapy with vincristine sulfate, etoposide, L-asparaginase and prednisone acetate (know as the VELP regimen). After 7 days of VELP chemotherapy, the skin lesions were ameliorated, hair loss was improved and lymphadenopathy disappeared. No lymphadenopathy or new skin lesions were observed during 6 months of follow-up.
