Arguments

 

Predilection for the head and neck (especially the mucous membranes) and limbs (particularly the arms and hand). Typically the lesion evolves rapidly, reaching its maximum size (usually less than 2 cm in diameter) within a matter of months. It presents as a pedunculated red or bluish nodule, which is prone to ulceration or bleeding.

Numerous small capillaries, often radiating from larger, more central vessels set in a loose edematous collagenous matrix. Endothelial cells have variably bland to plump nuclei and may be focally epithelioid, especially in mucosal tumors. Mitoses are commonly present and may be numerous
