Glomeruloid hemangioma associated with TAFRO syndrome.

Glomeruloid hemangioma is a rare cutaneous lesion that has been considered as a specific cutaneous marker of POEMS syndrome. Herein, we present the first case of glomeruloid hemangioma associated with TAFRO syndrome, a unique variant of idiopathic multicentric Castleman disease. The patient is a 74-year-old woman presented with fever, cervical lymphadenopathy, thrombocytopenia, bilateral pleural effusions and ascites. Biopsy of the lymph node revealed multicentric Castleman disease-like histology and bone marrow biopsy showed mild reticulin fibrosis, consistent with TAFRO syndrome. The patient simultaneously developed multiple skin lesions, which were histologically confirmed as glomeruloid hemangioma. Multiple immunoglobulin-positive granules were detected in the proliferating endothelial cells. Glomeruloid hemangioma is not specific to POEMS syndrome and can be a manifestation of TAFRO syndrome.
