Dermpath-India Pathology of Glomeruloid Hemangioma
|
Glomeruloid hemangioma is a term that was coined J.K.C. Chan and colleagues in 1990 because the condition is histopathologically similar to renal glomeruli. This vascular tumour is associated with POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, M-protein and skin changes). POEMS syndrome: definitions and long-term outcome .Blood, 1 April 2003, Vol. 101, No. 7, pp. 2496-2506 Glomeruloid hemangiomas are more common among Japanese and clinically presents as multiple red or purple papules. These lesions present most commonly on the trunk and extremities, but lesions on the head and neck and in extracutaneous tissues such as the uterus have been described. Microscopic features: Microscopically, a typical case of glomeruloid hemangioma is characterized by dilated vascular spaces (sinusoidal) in the superficial dermis containing aggregates of capillaries, resembling renal glomeruli. Around the capillaries there are large cells which stain positively with endothelial markers. Some PAS positive hyaline globules may be present.
These globules stain positively for immunoglobulins.
