Mycosis fungoides (MF) is a form of cutaneous T-cell lymphoma. Clinically, mycosis fungoides presents with a rash, pruritus, and at late stages, tumors. Disease is typically limited to the skin, but is known to occasionally involve visceral organs and the blood. Diagnosing MF can often be challenging because of its ability to mimic other benign dermatologic conditions both clinically and histopathologically. Further complicating this process is the fact that there are multiple histopathological subtypes of MF, including interstitial mycosis fungoides (IMF), a subtype that is scarcely reported in the available literature. Herein, a case of IMF is reported.
