Multiple Cervical Root Resorption in a Young Adult Female Previously Treated with Chemotherapy: A Case Report

Multiple idiopathic cervical root resorption is an aggressive form of external root resorption that occurs at the cementoenamel junction and can affect multiple teeth (a minimum of 3) throughout the entire dentition. Most of the individuals affected are healthy with noncontributory medical histories. The resorption is usually detected as an incidental finding on radiographs or during dental examination. This case report describes an adult female with multiple cervical root resorptions who had been treated with chemotherapy for ovarian cancer at 16 years old. Nine years later, a total of 12 teeth were diagnosed with cervical root resorption. All of the known causative factors for external cervical resorption were discarded. To our knowledge, this is the first case reported of multiple cervical root resorption related to chemotherapy.

Unusual Case of Inflammatory Myofibroblastic Tumor in Maxilla

Inflammatory myofibroblastic tumor (IMT) is a rare lesion found mostly in children and young adults and originates from the lung, abdominopelvic region, and retroperitoneum. Clinical manifestations of IMT or imaging are nonspecific and diagnosis is based on histopathological and immunohistochemical findings. Minority of all IMTs will metastasize. IMT in the oral cavity is an extreme rarity and this is a first case report of IMT in maxilla causing delayed tooth eruption and multiple cervical root resorption with an 11-year-old child. The IMT reported here was positive for smooth muscle actin, vimentin, and anaplastic lymphoma kinase (ALK1) with immunohistochemistry. Only three IMTs of the jaws have been reported so far and none of them had delayed root eruption and tooth resorption. This unusual case of IMT in a child was also ALK1- positive supporting neoplastic origin of her tumor. The case presented here underscores the importance of histopathological examination of the tissue found in any root resorption especially in the case of multiple resorptions.
