Abstract

Granular cell tumor (GCT) was first described by Abrikossoff in 1926. GCT is a rarely seen soft tissue tumor and is generally benign. While the tumor can be seen in all parts of the body it is generally located on the head and neck region, and especially on the tongue. GCT is rarely seen in the anal-perianal region. In accordance with literature this case was reported because it was thought to be the 27th anal-perianal located GCT case. In this case report, approximately 0,5-1 cm pedunculated polypoid lesion was determined in the perianal region during the physical examination of a 23 year old female patient who applied with palpable mass complaint in the perianal region. Lesion in the patient was totally excited with healthy skin-subcutaneous tissue under local anesthesia. A benign granular cell tumor was detected in the histopathological examination. Positive staining was monitored immunohistochemically with S-100 and neuron specific enolase (NSE). GCT is a rarely seen tumor in the anal-perianal region and its malign transformation rate is very low. Even lesions seen in the perianal region have clinically a benign appearance, a histopathological examination should be conducted and also GCT should be kept in mind during diagnosis. Malign-benign separation of these lesions is difficult so histopathological examination should be conducted with great care. Large local excision in the treatment provides curative treatment. But for those presenting malign transformation further examination must be performed for metastasis. After the treatment local recurrence and metastasis should be considered carefully. Prognosis of metastatic disease is very bad.
