Abstract:
Synchronous lingual granular cell tumor and squamous cell carcinoma (case report) Dr. D. Sadri* *-Assistant Professor of Oral & Maxillofacial Pathology Dept. – Faculty of Dentistry – Tehran Islamic Azad University. Introduction: For the first time, Abrikossof described granular cell tumor in 1926. It was firstly believed that this tumor originated from skeletal muscle but using electron microscope and immunohistochemistry technique (IHC). It has been generally accepted that this tumor has neural origin. Immunohistochemical markers such as S100, NSE and MBP are expressed by its tumoral cell. Synchronous lingual granular cell tumor and squamous cell carcinoma (SCC) is rare and only one case was reported in 1997 at Mountsinal faculty of medicine. Case Presentation: The present report is the second case in a 46- year – old man with persistant swelling and ulcer on dorsal tongue. Microscopic evaualtion by H & E and IHC technique for S100 protein and cytokeratin marker confirmed this diagnosis.Key words: Granular cell tumor – Squamous cell carcinoma – Dorsal tongue

Coexistence of Granular Cell Tumor with Squamous Cell Carcinoma on the Tongue: A Case Report
Introduction: Granular cell tumors (GCTs) are rare and mostly benign soft tissue tumors. Though they have been reported in all parts of body, they are generally located in the head and neck region, especially on the tongue. Some malign forms exist, but these have been rarely reported. Granular cell tumors have a neural origin and, in immunohistochemical evaluations, they express S-100 and neuro...

Background: Granular cell tumor (Abrikossoff’s tumor) is a rare and slow-growing tumor of the soft tissue. Originated from the Schwann cells, it is often a benign tumor, but it can be malignant in 1-3% of the cases. Malignant cases can cause significant morbidity and mortality. It may develop in many anatomic locations, especially in the head and neck region, and also in skin and subcutaneous t...

The granular cell tumor (GCT) is an uncommon, benign lesion with a preference for subcutaneous sites. In the head and neck, the tongue is the most common site, followed by the larynx. We experienced a case of a 27-year-old woman with lingual squamous cell carcinoma (SCC) surrounded by GCT. The pathological findings established that the lesion was SCC covered by GCT in the midline of the tongue....

Background: Primary intraosseous squamous cell carcinoma (PIOC) of the mouth is a very rare but well-known carcinoma. It is locally invasive and its prognosis is quite poor. It may originate from the walls of an odontogenic cyst or de novo from the remnant epithelium at this region. Because the early symptoms of such malignancies are sometimes similar to those of inflammatory or periodontal dis...

A rare case of squamous cell carcinoma ex pleomorphic adenoma in maxillary sinus is presented. The patient is a 50-year-old woman presenting with a slow-progressive swelling in left side of her face that she has noticed 2 years earlier. The lesion was not painful and caused asymmetry and mild exophthalmos. Microscopic examination revealed that the tumor was composed of two components partly of ...
