Mycosis Fungoides Mimicking Chronic Actinic Dermatoses-A Diagnostic Challenge !!!

Mycosis fungoides (MF) or cutaneous T cell lymphoma(CTCL) is a neoplasm with an indolent course having varied clinical and histologic manifestations. Various entities like Spongiotic dermatitis, allergic contact dermatitis, seborrhoeic dermatitis and other benign conditions like eczema and psoriasis may histologically and clinically mimick with mycosis fungoides and represent a potential trap for unsuspecting pathologists. An early diagnosis with vigilant follow-up and multiple biopsies can halt the further progression of the disease. Patients with only cutaneous involvement has a better prognosis compared to those with systemic involvement.
