Epitheloid hemangioendothelioma (EHE) is a rare vascular neoplasm of intermediate malignant potential. EHE commonly involves lungs, liver soft tissue, and bone. EHE is extremely rare in tongue and up to our best knowledge only nine cases of EHE of tongue reported in the literature. Clinically EHE usually presents as an asymptomatic mass. Microscopically, EHE exhibits proliferation of epitheloid cells and spindle shaped endothelial cells. Epitheloid cells show cytoplasmic vacuoles with few cells containing RBCs. A 34-year-old male presented to our institution with the chief complain of swelling on the base of the tongue from eight months. Surgical excision was done. An extensive work up of immunohistochemistry was done using different markers including CD 31, CD 34, Ki 67, Factor VIII, and BCL2. Correlation of histopathology and immunohistochemistry confirmed the diagnosis of EHE. The follow up period of 2 years was uneventful.

Centrally occurring salivary gland tumors are rare. Because of a considerable overlap between the clinical and histopathological features, this group of tumors often produces a diagnostic difficulty to the clinicians and oral pathologists. Acinic cell carcinoma (ACC) is an unusual, low-grade, malignant salivary gland tumor that represents approximately 2% of the salivary gland tumors with almost 90% arising in the parotid gland. The rest involve the submandibular and the minor salivary gland. ACC of the jaw is extremely rare and, to our knowledge, only 8 cases have been reported in the English literature. Herein, a case of primary intraosseous ACC of the mandible in a 31-year-old woman is presented. The present case is unique, as the central ACC has never been reported in a patient in the third decade of life. The complete surgical removal of the tumor was carried out under general anesthesia along with the extraction of teeth #31, #32, #41, and #42. The follow-up period of 1-year was uneventful.

Dear Editor-in-Chief Myxoid tumors of oral cavity encompass a broad spectrum of lesions, primarily neoplastic.(1) The significant variations in the biological behaviour; ranging from completely harmless to malignant neoplasm they require an accurate histopathological diagnosis to ensure a proper treatment. (2) Because of the considerable overlapping between the clinical and histopathological features, this group of tumors often produce a diagnostic difficulty to the clinicians and oral pathologists.(3) An exhaustive review of the literature reveals that there is no approved classification of myxoid tumors of oral cavity. A simple working classification of myxoid tumors is proposed here.

Pilomatrixoma is a benign tumor of hair follicle first described as calcifying epithelium (1). It accounts for 1% of all the benign skin tumors (2). It is a slow-growing, firm, dermal or subcutaneous neoplasm, usually measuring fewer than 3 cm in diameter. Pilomatricomas are considered benign; rarely recur after surgical excision (3). However, cases of pilomatrixoma with local recurrence and local invasiveness have been reported in the literature.
