ABSTRACT
Background: There are occasional reports of osseous metaplasia (OM) occurring in gastrointestinal polyps. We report 4 cases occurring in juvenile retention polyps. Case reports: Four juvenile retention polyps presented with rectal bleeding. Microscopically there was osseous metaplasia in addition to the typical surface ulceration and granulation tissue appearance. Discussion/conclusion: Osseous metaplasia was only detected on histopathologic examination of the resected polyps. Although the clinical significance is not established, OM suggests that the polyps have been present for a longer period of time.

INTRODUCTION: Pleomorphic adenoma (PA) is the most common benign salivary gland tumor. When neglected on some occasions, its size and weight can enormously augment. CASE PRESENTATION: We report a case of a giant submandibular pleomorphic adenoma in a 75 years old female patient which measured 34â¯×â¯26â¯×â¯20â¯cm and weighed 8.1â¯kg. CONCLUSION: Neglecting such tumors without treatment, can cause severe facial disfigurement and can even hinder the airway.
