Secondary hypereosinophilic syndrome: an unusual manifestation in a patient with syringotropic mycosis fungoides and human immunodeficiency virus infection.

ABSTRACT

Syringotropic mycosis fungoides is a very rare variant of cutaneous T-cell lymphomas characterised by prominent involvement of the eccrine glands. Hypereosinophilic syndrome refers to a rare group of conditions that are associated with persistent eosinophilia with organ involvement. It is classified into idiopathic, primary and secondary (reactive). We report herein an unusual case of hypereosinophilic syndrome with great impact on morbidity, which developed in a patient with human immunodeficiency virus infection and long-time misdiagnosed syringotropic mycosis fungoides.
