Ichthyosis with superimposed mycosis fungoides, a rare case of generalized erythema with malaise.

Ichthyosiform eruption of mycosis fungoides is rare, and ichthyosis with superimposed mycosis fungoides is scarcely ever seen; only a few cases have been documented in the medical literature. Furthermore, the patients with ichthyosiform lesions may indicate the presence of an underlying systemic disease, paraneoplastic syndrome, or an atypical manifestation of cutaneous T-cell lymphoma. Thus, determining the accurate etiology is important to establish the correct diagnosis and subsequently facilitate its management. They should be evaluated thoroughly, and a skin biopsy is essential to rule out the possibility of ichthyosiform mycosis fungoides.
