Non-infiltrating angiolipoma of the upper lip: A rare entity.

Sah K, Kadam A, Sunita J, Chandra S - J Oral Maxillofac Pathol (2012)

Bottom Line: It is the most common tumor of the forearm followed by trunk and extremities of young individuals.It's occurrence in head and neck region is rare.Toluidine blue stain is used to demonstrate increased mast cell density around blood vessels, speculating its role in vasculogenesis.

ABSTRACT
Angiolipoma is a variant of lipoma with a prominent vascular component. It is the most common tumor of the forearm followed by trunk and extremities of young individuals. It's occurrence in head and neck region is rare. In this report, we present clinical and histopathologic features of non-infiltrating angiolipoma occurring on the upper lip in a 9-year-old female. Toluidine blue stain is used to demonstrate increased mast cell density around blood vessels, speculating its role in vasculogenesis.

Figure 4: Numerous mature adipocytes with variable sized endothelial lined blood vessels (H and E stain, original magnification, ×10)

Mentions: Histopathologically, H and E stained section under low magnification revealed an encapsulated tumor mass consisting of adipose tissue separated by branched vascular network [Figure 3]. Thin walled small capillary like vessels were present at the periphery of the tumor mass [Figure 4]. Under higher magnification numerous mature adipocytes with variable sized endothelial lined blood vessels were seen [Figure 5]. Few areas show presence of fibrinous microthrombi [Figure 6]. Toluidine blue staining showed an increased mast cells density in and around blood vessels [Figure 7] with degranulation [Figure 8]. A diagnosis of non-infiltrating angiolipoma was made. Postoperative course of the patient was favorable. There were no sign or symptoms of recurrence 6 months after surgery.
