The granular cell tumor is an uncommon tumor that usually appears as a solitary small nodular growth and runs a benign course. It occurs widely throughout the body, but is rarely described in the abdominal wall. The authors report a case of malignant granular cell tumor which was arising in anterior abdominal wall of a 67-year-old woman. Malignant variant is rare and the abdominal wall site is ...

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...

A young Caucasian woman is described in whom obstructive jaundice was caused by a granular cell myoblastoma of the common bile duct. She was treated by percutaneous transhepatic biliary drainage for 10 days, before radical removal. Granular cell myoblastomas are benign lesions of disputed histogenesis, rare among biliary neoplasms, the excision of which is curative.

T-cell large granular lymphocyte leukemia (LGLL) is a rare clonal disease often associated with rheumatoid arthritis (RA) and manifests chiefly as neutropenia and recurrent infections. Immunosuppressive agents are the mainstay of treatment, but long-term remissions are rare. We report 2 cases of LGLL in patients with RA successfully treated with rituximab, a monoclonal antibody specific of B ce...

Granular [correction of Granulosa] cell tumors are rare benign tumors which may be found throughout the body. Rare cases are isolated within the biliary tree. If completely resected, surgical excision is curative. A case of biliary duct granular [correction of granulosa] cell tumor is presented with review of the world's literature on this topic.

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.

Granular cell tumors are rare soft tissue neoplasms, among which only 2% are malignant, arising from nervous tissue. Here we present a case of a large esophageal granular cell tumor with benign histopathological features which metastasized to the liver, but showing on positron emission tomography-computerized tomography standardized uptake value suggestive of a benign lesion.

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...

INTRODUCTION Granular cell tumor is an uncommon neoplasm that can occur in any part of the body, including the orofacial region. The tumor is usually benign, but there are reports of cases in which the tumor shows a locally aggressive behavior, malignancy, and distant metastases. The most widely accepted hypothesis is that granular cell tumor arises from the altered metabolism of Schwann cells....
