Porokeratosis and mycosis fungoides: cause/result or an association or neither? A case report

Mycosis fungoides (MF) is a great imitator. It can resemble more than 50 different clinical disorders. Porokeratosis is the rarest of the disorders and has been reported only in three cases. Herein, we present three cases of porokeratosis occurring in MF patients. The first case proved to be MF lesions upon histopathological examination, whereas the second case showed a classic porokeratosis occurring in association with MF in the same lesion. Finally, the third case was presented with classic porokeratosis that developed in a longstanding MF case undergoing treatment with Methotrexate and PUVA.
