Histiocytoid Sweet's syndrome in a patient with myelodsyplastic syndrome: report and review of the literature.

The neutrophilic dermatoses are a group of disorders characterized by skin lesions for which histological examination reveals intense epidermal and/or dermal inflammatory infiltrates composed primarily of neutrophils without evidence of infection. The myelodysplastic syndromes consist of a heterogeneous group of malignant hematopoietic stem cell disorders characterized by dysplastic and inadequate blood cell production with a variable risk of transformation to acute leukemia. Rarely, histiocytoid Sweet's syndrome occurring in patients with myelodysplastic syndrome has been described.

Elastosis perforans serpiginosa secondary to D-penicillamine therapy with coexisting cutis laxa.

Elastosis perforans serpiginosa (EPS) is a rare complication of D-penicillamine therapy. EPS has been reported in patients with Wilson disease, cystinuria, and rheumatoid arthritis after many years of high-dose therapy. We report a case of D-penicillamine-induced EPS with coexisting acquired cutis laxa in a patient with cystinuria.
