Glomeruloid hemangioma leading to a diagnosis of POEMS syndrome.
POEMS is an acronym for polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes. It is a poorly understood paraneoplastic syndrome that stems from an underlying plasma cell dyscrasia. Of the skin changes, the glomeruloid hemangioma is considered to be a specific marker of POEMS syndrome. We describe a 68-year-old man who presented to his dermatologist with multiple hemangiomas, whose biopsy diagnosis of glomeruloid hemangioma resulted in further evaluation and an eventual diagnosis of POEMS.

Thalidomide in the treatment of recalcitrant Sweet's syndrome associated with myelodysplasia.
Sweet's syndrome is a neutrophilic dermatosis characterized by tender, erythematous, pseudovesicular plaques that can be associated with hematologic malignancy. We report a patient with recalcitrant Sweet's syndrome that preceded the development of myelodysplastic syndrome by 30 months. The delay between the onset of Sweet's syndrome and the subsequent diagnosis of myelodysplasia highlights the need for thorough and repeated evaluation for underlying malignancy in patients with such a course. Although corticosteroids are the initial treatment of choice, this patient's eruption was only partially responsive to high-dose prednisone and was refractory to metronidazole, dapsone, and methotrexate. Treatment with thalidomide resulted in complete resolution of the cutaneous lesions within one month of therapy.
