RESUMO
Oral schwannomas (OSs) are uncommon benign nerve sheath tumors accounting for 1% of all schwannomas and may arise from either soft tissue or bone. Cellular schwannoma is a rare histological variant of schwannoma which is characterized by increased cellularity. The most common intraoral site of occurrence is the tongue followed by the floor of the mouth and palate. Here, we are reporting a rare case of intraoral cellular schwannoma involving both facial and palatal gingiva of the right maxilla in a young Indian male patient.
RESUMO
Fibromyxoma is a locally aggressive rare benign tumor of mesenchymal origin with or without odontogenic epithelium. The etiology of this tumor remains unknown and it is responsible for approximately 3-8% of all cysts and tumors. Another locally destructive benign lesion is central giant cell granuloma (CGCG) which contains osteoclast-like multinucleated giant cells. CGCG accounts for about 7% of all benign jaw tumors, which usually affects younger females. A hybrid lesion with histologic features of both central fibromyxoma and CGCG has not been reported in the literature so far. In the present article, we report the first case of a hybrid tumor comprising odontogenic fibromyxoma with CGCG in a female along with a brief review of its clinical presentation, radiographic features, histological features, and management.
