- Extraoral examination reveals a normal TMJ, no muscle tenderness, and no lymphadenopathy
- Intraoral examination reveals a well-defined (~ 2.5 cm x 1.5 cm) lobulated, pedunculated, smooth surfaced, soft tissue mass arising from the posterior right buccal mucosa. There is evidence of apparent surface irritation but there is no induration. An excisional biopsy is performed and the tissue submitted for histopathologic examination.
The biopsy shows an ulcerated inflamed exophytic nodular lobulated proliferation of granulation tissue. The inflammatory infiltrate consists of neutrophils, eosinophils, lymphocytes, plasma cells and histiocytes. The stroma is edematous and contains numerous ectatic congested thin-walled vascular channels lined by plump reactive endothelial cells. The adjacent surface epithelium is hyperplasia and hyperparakeratotic.
