Ichthyosiform mycosis fungoides: a neoplastic acquired ichthyosis.

Sir, Acquired ichthyoses can either reflect an underlying severe disorder or may be an atypical expression of skin diseases such as cutaneous T-cell lymphomas (1). Otherwise, lymphomatous infiltrates in the skin can cause heterogeneous cutaneous symptoms and lesions, which may range from invisible features to massive tumour nodules. Mycosis fungoides is an epidermotropic cutaneous T-cell lymphoma, which accounts for almost 50% of all primary cutaneous lymphomas. Subtypes and variants may complete its wide clinicopathological spectrum (2). Ichthyosiform mycosis fungoides is a rare variant of mycosis fungoides observed in 1.8% of cases (3–5). We describe here a case of ichthyosiform mycosis fungoides in a 30-year-old man who presented a wide spread ichthyosiform appearance coexisting with limited conventional papular lesions.
