Sialadenitis)3. Maxillary Sinus Retention

Cyst/Pseudocyst4. Necrotizing Sialometaplasia5. Adenomatoid Hyperplasia

Benign Neoplasms :

2. Monomorphic Adenomas3. Ductal Papillomas

Malignant Neoplasms :

1. Mucoepidermoid Carcinoma2. Polymorphous Low-Grade

Adenocarcinoma3. Adenoid Cystic Carcinoma4. Clear Cell Carcinoma5. Acinic Cell Carcinoma

Rare Tumors :

1. Carcinoma Ex-Mixed Tumor/Malignant Mixed Tumor/Metastasizing Mixed

2. Tumor3. Epimyoepithelial Carcinoma4. Salivary Duct Carcinoma5. Basal Cell Adenocarcinoma6. Squamous Cell Carcinoma

Necrotizing Sialometaplasia is a benign condition that typically

affects the palate and rarely other sites containing salivary glands. Recognition of this entity is important because it mimics malignancy both clinically and microscopically.

Clinical Appearance :

Junction of hard and soft palates Unilateral or bilateral Swelling, erythema, tenderness,

followed by ulceration
