ABSTRACT

Hemangiomas are the most frequent vascular skin neoplasms, but there are no studies defining their frequency.
Objectives: To determine the frequency of presentation in the different cutaneous hemangiomas in biopsy specimens submitted to our service, and to verify the level of clinicopathological correlation established in cutaneous hemangiomas.
Methods: Archives of biopsy reports and specimens of any kind of cutaneous hemangiomas submitted in a ten year period.
Results: In a ten year period, 18.142 biopsies were submitted, which 520 specimens (2.86%) belonging to the hemangioma category. The most frequent tumor was pyogenic granuloma (56.5%), followed by capillary hemangioma (17.5%), cherry hemangioma (10%) and venous hemangioma (7.1%). Other hemangiomas were less common. We found hobnail endothelial cells in pyogenic granuloma (n = 68), capillary hemangiomas (n = 6) and venous hemangiomas (n = 6). We described some mixed (collision tumors) hemangiomas.
Conclusions: In cutaneous biopsy specimens, pyogenic granuloma was the most frequent vascular benign neoplasm; followed by capillary heman-gioma (adult type), cherry angioma and venous hemangioma. Other tumors are uncommon. We found some collision tumors (capillary and venous hemangioma, hemangioma and intradermal melanocytic nevus). The finding of hobnail cells in cutaneous hemangiomas is a novel finding and its clinical significance remains obscure. The clinicopathological correlation of cutaneous hemangiomas (beside from pyogenic granuloma) remains very low.
