A Simplified Working Classification Proposed for Myxoid Tumors of Oral Cavity

Myxoid tumors of the oral cavity encompass a broad spectrum of lesions, primarily neoplastic (1). Significant variations in the biological behavior ranging from completely harmless to malignant neoplasm require an accurate histopathological diagnosis to ensure a proper treatment (2). A considerable overlapexists between clinical and histopathological features of these group of tumors, which often produces a diagnostic difficulty to clinicians and oral pathologists (3). There is no approved working classification for myxoid tumors of the oral cavity in the literature. A simple working classification of myxoid tumors is proposed here (Table 1)
