Calcifying epithelial odontogenic tumor (CEOT) is a benign epithelial odontogenic tumor occurring most frequently in the posterior part of the lower jaw. Extraosseous CEOT is one of the rarest forms of this tumor, and few such cases involving the maxillary gingiva have been reported in the literature. Here we present a case that showed progressive enlargement in the left maxillary gingival area...

Granular cell tumor is an uncommon benign hamartomatous lesion occurring in almost any part of the body. Granular cell lesions may be found in other diverse sites, such as the jaw, skin, gastrointestinal tract and respiratory tract. The tongue and buccal mucosa are common intraoral sites. The histogenesis of the lesion remains unknown. In this paper, we report the occurrence of an oral granular...

Granular cell tumors (GCTs) are uncommon neoplasm. They can originate in any part of the body. The most common sites of origin are in the head and neck, while the larynx is a relatively uncommon location. Patients affected with a laryngeal GCT typically present with persistent hoarseness, stridor, hemoptysis, dysphagia, and otalgia but, the tumor may be asymptomatic. Care must be taken to diffe...

BACKGROUND: Malignant granular cell tumor (MGCT) is a rare disease entity. Forty-one well-documented MGCTs have been reported in the world literature. CASE REPORT: This report describes a patient who presented with a MGCT of the lung and reviews the preoperative evaluation, pathologic features and differential diagnosis of the disease. This case represents the first report of resected primary p...

introduction: diabetes mellitus is associated with nervous system alterations in both human and animal models. this study was done to determine the effect of gestational diabetes on the purkinje and granular cells in the cerebellum of rat offspring.  methods: 10 wistar rats dams were randomly allocated in control and diabetic group. the experimental group received 40 mg/kg/body weight of strept...

Granular cell tumors are rare tumors of Schwann cell origin that arise from tissues of neural crest and mesenchymal origin. We report the clinical, radiographic, and pathological features of a pleural-based granular cell tumor in a 60-year-old African American man.

malignant peripheral nerve sheath tumor (mpnst) is a rare malignant tumor that develops either from a preexisting neurofibroma or de novo. the cell of origin is believed to be the schwann cell and possibly other nerve sheath cells. in this report, we describe a rare case of mpnst that arise from the socket of second left maxillary molar that has been already extracted in a young man. he was ref...
