Penile ulcer as a specific clinical manifestation of Waldenstrom’smacroglobulinemia

摘要

Waldenstrom’s macroglobulinemia is considered a lymphoma by the World Health Organization. Cutaneous lesions, particularly of a specific type, are rare occurring in 5% of patients. What draws attention in this case is the unusual cutaneous clinical manifestation and its location on the genitals, which has not been described in researched literature, therefore imposing differential diagnosis with other etiologies of genital ulcers.
