(vascular leiomyoma): a clinicopathological study.
Differential diagnosis includes keloid scar, mucocele, salivary gland tumor (most likely canalicular adenoma of a small salivary gland within the lip), lipoma, neurilemmoma and neurofibroma (clinically reminiscent of angiomyoma
, but immunohistochemically different), and possibly granular cell tumor.
The lump, diagnosed as angiomyoma
, started growing from Reynald's chest when he was 15.
Microscopically, LLH should be differentiated from a solid oral leiomyoma and an angiomyoma
(angioleiomyoma; vascular leiomyoma); the solid leiomyoma is a true neoplasm of smooth-muscle origin, which is rare in the oral cavity .
The lesion must be distinguished histologically from other tumors and "pseudotumors" such as lipoma, angiolipoma, angioleiomyoma, angiomyoma
, liposarcoma, alpha 1-antitrypsin deficiency-associated panniculitis, membranocystic, and pancreatic fat necrosis (6, 8, 21).
The most frequent form of leiomyoma is angiomyoma
(74%), which is followed by solid leiomyomas (25%).

Angioleiomyoma, also known as vascular leiomyoma or angiomyoma
, was first described by Stout et al, (1) in 1937.

, hemangioma and neurilemmoma.
Gosney, "Oral angiomyoma
: a case report," British Journal of Oral Surgery, vol.
(1,2) Three types of leiomyoma have been described: common, vascular (angiomyoma
), and epithelioid.
