The importance of lymph node examination: Simultaneous diagnosis of hypopigmented mycosis fungoides and follicular B-cell lymphoma

Mycosis fungoides (MF) is the most common type of cutaneous T-cell lymphoma (CTCL). Its typical course is characterized by a progression of patches, plaques, and tumors. Follicular B-cell lymphoma, the second most common non-Hodgkin lymphoma (NHL), presents with lymphadenopathy and is characterized by a translocation between chromosomes 14 and 18, resulting in overexpression of the B-cell lymphoma (bcl)-2 gene. In most patients, the course of each of these lymphomas is indolent with slow progression.
