Angiomatosis: A Rare Vascular Proliferation of Head and Neck Region.

Angiomatosis is a diffuse vascular lesion which clinically mimics hemangioma or vascular malformation. It usually involves multiple tissues and is histopathologically characterised by proliferation of vessels of varying calibre intimately admixed with large amount of adipose tissue. Its surgical removal is very difficult because of its infiltrative nature. Therefore, a precise histopathological diagnosis is of utmost importance. It is usually seen in females in the first two decades and commonly involves lower extremities. Angiomatosis of head and neck region is very rare. Here we present a rare case of angiomatosis of the lower face involving right cheek and lip in a 4-year-old boy clinically diagnosed as hemangioma. Histopathological differential diagnosis of angiomatosis is also discussed.
