Abstract
|
|
|
|
Granular cell tumor (GCT) is a relatively rare tumor. GCT can originate from any site of human body, including subcutaneous tissue, skin, breast, digestive system and respiratory system. It occurs mostly in the head and neck region, especially in the oral cavity and tongue. Histopathologically, GCT consists of polymorphic and polygonal cells. The cytoplasm of cells has abundant eosinophilic granules. In immunohistochemical studies, these eosinophilic granules appear positive for S-100 protein. Surgical excision is the first choice of treatment of GCT; recurrence is rare when proper excision is done with a sufficient margin. We have experienced a case of GCT that originated from the postauricular area, and report this case with a review of literatures.
