Extensive ameloblastic fibroma of the mandibula in a female adult patient: A case report with a follow-up of 3 years

Highly Proliferative Ameloblastic Fibroma: A Rare Entity

Ameloblastic fibroma (AF) is a rare odontogenic neoplasm which is commonly seen in the second decade of life. It is seen most frequently in the mandibular posterior region. AF shows clinical and radiographic resemblance with other commonly occurring odontogenic cyst and tumors. Histopathologically, it shows great resemblance with primitive dental papilla. Immunohistochemistry helps in understanding the nature and proliferative potential of tumor and helps in proper treatment planning. Large lesions and recurrent lesions are treated with segmental resection which can often lead to morbidity, especially in young patients if not managed properly. Herein, we present a case of a large AF in the posterior mandible region in a 21-year-old female patient with significant expansion and erosion of cortical plates and lower border of the mandible with a high Ki67 proliferative index (20%) which was surgically treated by segmental resection and immediate reconstruction by autogenous iliac graft.

Pleomorphic Adenoma in the Lower Lip: A Case Report and a Review

Pleomorphic adenoma constitutes 50% of salivary gland tumors affecting mostly the parotid gland extraorally, and the palate intraorally. While the upper lip is a common site, it is unusual to encounter this tumor in the lower lip. A 26-year-old man complained of a persistent lump affecting the lower lip. The lesion was excised and was shown on histopathological examination to be a pleomorphic adenoma with squamous metaplasia. At the 18-month review appointment, there was complete healing and no recurrence. Pleomorphic adenoma in the lower lip should be considered among the differential diagnosis of lower labial swellings, especially in young patients. There needs to be reconsideration of the epidemiological and histological characteristics.
