Granulomatous mycosis fungoides--a diagnostic challenge

An Bras Dermatol. Jul-Aug 2015;90(4):554-6. doi: 10.1590/abd1806-4841.20153460.


Granulomatous mycosis fungoides is a rare subtype of T-cell cutaneous lymphoma. Due to its clinical heterogenicity the diagnosis is delayed and based on histopathological and immuno-histochemical findings, sometimes requiring gene rearrangement studies for confirmation. We report the case of a patient who was submitted to several biopsies before diagnostic conclusion.
