Erythema annulare centrifugum-like mycosis fungoides

ABSTRACT A considerable number of recent reports have documented mycosis fungoides resembling many other dermatoses. Due to highly variable presentations and the sometimes non‐specific nature of histological findings, an accurate diagnosis of mycosis fungoides can be difficult. Erythema annulare centrifugum‐like mycosis fungoides with a variety of annular, polycyclic erythematous skin lesions is a recently recognized atypical manifestation of mycosis fungoides, and only a few cases have been reported to date.
