Granular cell tumors are uncommon soft tissue neoplasm of nerve sheath origin, which are predominately benign. Granular cells can be found at any site in the body including the tongue, skin, subcutaneous tissue, breast, gastrointestinal, and urogenital systems. However, granular cell tumors have only been rarely described in the chest wall. Here we report a case of a granular cell tumor that oc...

This was an extremely rare case of unusual granular cell tumor of the trachea coexisting with recurrent papillary thyroid carcinoma. We initially misdiagnosed this patient as having tracheal invasion from recurrent thyroid carcinoma even after a computed tomography scan and fine-needle aspiration cytology.Clinicians should be aware of the possibility of granular cell tumor of the trachea occurr...

Granular cell tumors are predominantly benign, occurring more commonly in women, with about 10% developing in the gastrointestinal tract. Rectal location of this tumor is very rare. We herein report one such case of a 61-year-old man with granular cell tumor in the rectum who underwent endoscopic curative resection.

BACKGROUND Granular cell tumor (GCT) is a benign soft tissue tumor of neural origin and is characterized by eosinophilic granular cells showing positivity for neuronal markers. Herein, we report the first case of primary intraosseous GCT arising in the maxilla of an adolescent girl. METHODS AND RESULTS A 16-year-old female patient presented with palatal swelling. Radiographic findings reveale...

conclusions based on evidence, dentists and dental health care professionals should consider periodontal disease as a risk factor for the development of neoplasms in the oral cavity. it also seems a good idea to provide periodontal therapy for patients with cancer to achieve ideal therapeutic results. results cancer of the oral cavity and periodontal disease are related from different aspects. ...

We report a rare case of granular cell tumor arising in the left lower lobe (LLL) bronchus with secondary obstructive change in a 60-year-old male. The patient was found to have a nodule in the LLL on a computed tomography scan, three months prior to his presentation to the Asan Medical Center. Bronchoscopic biopsies revealed a granular cell tumor. After undergoing LLL lobectomy with bronchopla...

BACKGROUND Granular cell tumors are benign lesions that typically occur in the oral cavity, but can also be found in other sites. However, the characteristics of these tumors are unclear. Thus, the present study aimed to investigate the immunohistological characteristics of these tumors of the tongue. METHODS Seven patients were treated for granular cell tumors of the tongue at our institutio...

We investigated the expression and localization of connexins (CX) 26 and 43 in the rat gingival epithelium. RT-PCR analysis revealed CX26 gene expression in both the upper and lower layers of the gingival epithelium and in the total epithelial layer, whereas CX43 gene expression was limited to the lower layer and the total epithelial layer. Immunoreactivity for CX43 was observed in the membrane...
