Cherubism: case reports and literature review.

Two new cherubism cases have been documented and reported. Both were relatively mild clinically, being a Grade I within Motamedi's I to V clinical grading system. Each presented with bilateral posterior mandibular lesions having a multiloculated radiolucent appearance. In each case, detection with eventual diagnosis evolved from a mandibular molar failing to erupt (tooth No. 19). The partial literature review documented the wide spectrum of clinical expression of this disease and the consequent wide variation in its treatment.

Squamous cell carcinoma in an American bison (Bison bison bison).

The following case report is, to the best of our knowledge, the first documentation of a squamous cell carcinoma in a full-blooded American bison (Bison bison bison). This female bison developed an ulcerated lesion on the left flank, at the site of a brand, in the summer of her eighth year. In the winter of her ninth year, as the lesion continued to grow, a biopsy was performed, and a diagnosis of squamous cell carcinoma was made. Ultimately, there was metastasis to the liver, a lung, and a prefemoral lymph node.

Surgical treatment of central epithelial ghost cell tumor.

A surgical treatment for central epithelial odontogenic ghost cell tumor is described. A brief review of the literature is given, and histopathology is discussed. The rationale for conservative treatment is presented, along with an illustrative case report.
