Ectomesenchymal chondromyxoid neoplasm. An unusual presentation. A case report.

Ectomesenchymal chondromyxoid tumor (ECMT) is a rare benign intraoral tumor. Clinically, it presents as a slow growing, painless, firm, submucosal swelling exclusively occurring on the anterior dorsum of the tongue. Till date not more than 45 cases have been reported in literature. Histopathologically the tumor is characterized by a well circumscribed, lobular proliferation of round, polygonal, ovoid or fusiform cells in a net-like pattern in a myxoid to chondromyxoid background. Here, we present a rare case of ECMT occurring in a 17 years old male who presented to us with chief complaint of slow growing painless mass arising from anterior Dorsum of the tongue measuring about 1.5cms×1.5cms. Mass was completely resected as excisional biopsy, it was found un encapsulated with muscle entrapment.
