Présentation Clinique



Clinical Setting


M 53 ans. Lésion végétante du bras droit évoluant depuis 1 mois, saignante au contact. Resection chirurgicale


M 53 yo. Fungating lesion of the arm, a month duration, bleeding on contact. Surgical excision.


Diagnostic Proposé:

Granulome pyogénique (Hémangiome capillaire lobulé)

Proposed Diagnosis:

Lobular capillary hemangioma (pyogenic granuloma)




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
