What is the MOST likely diagnosis?
Show answer and explanation
Correct answer: B. Peripheral giant cell granuloma (PGCG)
A RECURRING (after excision) gingival lesion that is bluish-purple to reddish, pedunculated, with a history of recurrence suggests Peripheral Giant Cell Granuloma (PGCG). PGCGs recur more than pyogenic granulomas. PGCG also shows cup-shaped bone resorption on X-ray. Pyogenic granuloma is highly vascular/bleeds easily. PGCG = the 'recurrent' gingival lesion on boards.
