Treatment of cherubism with salmon calcitonin: a case report

Cherubism is a familial disease of the jaws which is inherited via autosomal dominant manner. Typical features of cherubism include a painless bilateral, symmetrical enlargement of the jaws, misalignment of teeth, and intra-osseous central giant cell granuloma-like lesions, which are usually evident in early childhood. Treatment of cherubism consists of local curettage of the lesions, jaw contouring, intralesional steroid injections, and systemic calcitonin administration as well. Calcitonin therapy for central giant cell granuloma of the jaws is well documented, and favorable results have been achieved. However, fewer reports have been presented in regard to calcitonin administration for cherubism. In the present report, a 14-year-old boy with cherubism who had intra-osseous cherubic lesions in his mandible was treated with an administration of 200 IU systemic calcitonin every other day via his nasal passage for duration of more than two years. After 30 months of calcitonin therapy, the lesions in the mandible were significantly regressed, and calcitonin application was ceased. Despite some drawbacks, such as unpredictable efficient absorption and patient tolerability, nasal administration is the easiest way to use calcitonin therapy on children. In this report, every-other-day applications of calcitonin increased patient tolerability and might be considered as an effective treatment for mild cherubic lesions.     

Temporal bone involvement in cherubism: case report

Cherubism is a rare benign hereditary fibro-osseous disease involving the mandible and maxilla. We report a case of cherubism in a 10-year-old girl for which the panoramic radiograph was insufficient for diagnosis of the disease. Clinical, histological, and radiological findings were discussed. The CT was taken and it confirmed not only the involvement of the jaws but also of the temporal bone. This was not found in the conventional radiograph.     

Orbital infection arising from a primary tooth: a case report

Odontogenic infections may spread to the orbit by one or more of several paths. Such extension is potentially dangerous and may lead to loss of vision. A case of infection from a primary tooth, which extended to the retrobulbar area is presented in this report. Treatment included surgical drainage of the resulting subperiosteal orbital abscess through a Caldwell-Luc approach as well as aggressive antibiotic therapy. The importance of early suspicion of this entity and its potential sequelae are discussed.     

Adenomatoid odontogenic tumor arising in a dental cyst: report of unusual case

The case of an adenomatoid odontogenic tumor developing over a dentigerous cyst is reported. A 12-year-old boy was referred by his pediatric dentist to the service of Oral and Maxillofacial Surgery of the Asturias Central Hospital (Spain) for evaluation of a radiolucent image compatible with a dentigerous cyst. Microscopic examination revealed the presence of an adenomatoid odontogenic tumor located over the linear epithelium of a dentigerous cyst. Based on the literature, the clinico-pathological, diagnostic, radiological and therapeutic characteristics of the case are commented in detail.     

Unilateral mandibular cherubism: brief review and case report

A case of unilateral cherubism is presented in which only one side of the mandible was affected. The associated diagnostic features are discussed.

Papillary cystadenoma arising from the upper lip: a case report

We report a rare case of a papillary cystadenoma arising from the upper lip. This tumor was not distinctly encapsulated and had proliferated replacing the ductal epithelium. Mast cells were found not only in the stroma but also in the oncocytic epithelial layer. There was a strong immunoreaction with mitochondrial antibody in the epithelial layer. Only one case (0.9%) of papillary cystadenoma has occurred among the 110 benign intraoral salivary gland tumors seen in our hospital from 1966 through September 2003.     

Malignant fibrous histiocytoma: a case report

Malignant Fibrous Histiocytoma (MFH) is a controversial soft tissue malignancy whose pathogenesis continues to be redefined. It remains the most often used term for soft tissue sarcomas of late adult life. It has also been described to originate from the bone and rarely found in the mandible. Primary involvement of the mandible with MFH is an unusual presentation. A case of malignant fibrous histiocytoma, which posed a diagnostic difficulty, is presented here.     

Adenomatoid odontogenic tumor arising from the mandibular molar region: a case report and review of the literature

This case report describes a rare case of an adenomatoid odontogenic tumor (AOT) arising in the mandibular third molar region of a 20-year-old female. The tumor was a well-circumscribed intraosseous lesion with an embedded tooth. Histologically, the induction of extensive globular calcification was evident in addition to the characteristic histological features of AOT. The present case lends support to the categorization of AOT as an odontogenic tumor consisting of a disorderly mixture of odontogenic epithelium and odontogenic ectomesenchyme with calcification.

Peripheral dentinogenic ghost-cell tumor: a case report.

The dentinogenic ghost-cell tumor is a rare solid variant of the calcifying odontogenic cyst. Few peripheral cases of this tumor with clinical and radiographic documentation have been reported. A case of peripheral dentinogenic ghost-cell tumor is presented and the literature is reviewed.     

A condylar tumor from pre-Columbian Chile: a case report

A case of an expansile, multilocular lesion in a condyle recovered in skeletal remains more than 700 years old is discussed. Gross, radiologic, and histologic studies were accomplished on the specimen. Although a definitive diagnosis could not be arrived at because of the age of the specimen, differential diagnoses are presented.
