ABSTRACT

Odontogenic myxoma is a rare intraosseous neoplasm, which is benign but locally aggressive. It rarely appears in any bone other than the jaws. It is considered to be derived from the mesenchymal portion of the tooth germ. Clinically, it is a slow-growing, expansile, painless, non-metastasizing, central tumor of jaws, chiefly the mandible. Here we report the case of a typical odontogenic myxoma in a 26-year-old female patient, which had acquired large dimensions and involved the entire left half of the mandible including the ramus, resulting in a gross facial deformity, within a span of one and a half years.

ABSTRACT

Odontogenic cysts comprise a diverse group of exceptional lesions derived from epithelial elements of the tooth-forming apparatus. Calcifying cystic odontogenic tumor is a rare odontogenic lesion, which represents about 2% of all odontogenic tumors and cysts. It may occur in a central (intraosseous) or peripheral (extraosseous calcifying cystic odontogenic tumor [ECCOT]) location. ECCOT in contrast to central, tends to affect the older patients, commonly located in the anterior lower jaw, is less aggressive and the recurrence is rare. Here, we report clinico-pathological and radiographic features of ECCOT located in relation to 48 (posterior lower jaw) measuring about 1 cm in the greatest diameter in a 17-year-old male.

ABSTRACT

Our case of ameloblastoma had a surprisingly long 25 year history, with abnormally large dimensions, a multilocular diffuse-mixed radiographic picture, and was histopathologically diagnosed as granular cell ameloblastoma with desmoplasia. To the best of our knowledge, this is the first ameloblastoma ever reported, that has shown combined features of granular cells, desmoplasia, ameloblastic follicles, plexiform, and acanthomatous patterns. The nature of granular cells in this type of tumor and the significance of their presence have also been reviewed. From the studies on ameloblastomas to date, it seems that the old belief that granular cell ameloblastoma is the most aggressive variant of ameloblastoma is a myth, and in all probability, granular cells are just a transitional or matured phase in the life cycle of ameloblastomas, starting with normal stellate reticulum-like cells, leading to a production of granules and finally leading to degeneration and formation of cystic areas.
