Granular cell tumors.
The skin and subcutaneous tissue and mucosae of the head and neck are areas of predilection for granular cell tumors. These often histogenetically enigmatic lesions have two principal clinicopathologic presentations: an infantile (congenital) epulis form of the gnathic gingiva and a noncongenital soft tissue and aerodigestive form. Recurrences of either form are largely attributable to marginal excision and, for all sites, approach 15%. A malignant granular cell tumor is recognized, but requires rigorous histologic confirmation.
