Recurrent granular cell tumor: how to treat.

Granular cell tumor is an uncommon lesion usually located in the head and neck region (50%) with a female sex predominance. It is believed to be of primitive neuroectodermal origin. Typical clinical presentation is a small, uninflamed, slowly growing, yellowish mass approximately 2 cm in diameter. Granular cell tumor has a peculiar clinical behavior ranging from clearly benign, locally aggressive, or manifestly malignant. Treatment is surgical excision, but recurrences are possible. In this article, we present a case of recurrent benign granular cell tumor with the discussion of the treatment modalities. The patient was a 16-year-old girl with a 3-year history of a painless mass on the right side of her neck. The mass was excised two times at different centers and diagnosed as granular cell tumor after the pathologic examination. The time interval between the operations and recurrences was approximately 1 year. On physical examination, a yellowish, firm, nodular mass measuring approximately 2 x 1 cm was noted. Cervical lymph nodes were evaluated with ultrasonography preoperatively to exclude metastasis and no pathologic lymph nodes were noted. The lesion was excised under local anesthesia with a 1-cm safe margin and the resulting defect was closed primarily after undermining of the wound edges. Postoperatively, the wound began to heal with a hypertrophic scar and immediate precautions were taken. Topical steroid treatment and silicone blocks were applied. Now the patient is in the sixth postoperative month and followed up every month for signs of recurrence.
