Summary of "Well-Differentiated Liposarcoma/Atypical Lipomatous Tumor of the Oral Cavity: Report of Three Cases and Review of the Literature."

Atypical Lipomatous Tumor/Well Differentiated Liposarcoma (ALT/WDLS) is a soft tissue sarcoma of intermediate malignant behavior, most frequently affecting the retroperitoneum and lower extremities. Oral liposarcomas are very rare neoplasms, the most common histological subtype being ALT/WDLS. In this study, three additional cases of ALT/WDLS located on the tongue (2 cases) and the lower lip (1 case), respectively, are described. Analysis of the salient clinicopathologic features of 63 oral ALT/WDLS cases previously reported in the English language literature, as well as of the 3 cases presented in this study, indicates that the indolent biologic behavior of this tumor justifies its designation as a locally spreading malignant neoplasm, affording a rather conservative surgical approach.

Medical and Biotech [MESH] Definitions

A malignant tumor derived from primitive or embryonal lipoblastic cells. It may be composed of well-differentiated fat cells or may be dedifferentiated: myxoid (LIPOSARCOMA, MYXOID), round-celled, or pleomorphic, usually in association with a rich network of capillaries. Recurrences are common and dedifferentiated liposarcomas metastasize to the lungs or serosal surfaces. (From Dorland, 27th ed; Stedman, 25th ed)

The oval-shaped oral cavity located at the apex of the digestive tract and consisting of two parts: the vestibule and the oral cavity proper.

A variant of well-differentiated epidermoid carcinoma that is most common in the oral cavity, but also occurs in the larynx, nasal cavity, esophagus, penis, anorectal region, vulva, vagina, uterine cervix, and skin, especially on the sole of the foot. Most intraoral cases occur in elderly male abusers of smokeless tobacco. The treatment is surgical resection. Radiotherapy is not indicated, as up to 30% treated with radiation become highly aggressive within six months. (Segen, Dictionary of Modern Medicine, 1992)

A benign, slow-growing tumor, most commonly of the salivary gland, occurring as a small, painless, firm nodule, usually of the parotid gland, but also found in any major or accessory salivary gland anywhere in the oral cavity. It is most often seen in women in the fifth decade. Histologically, the tumor presents a variety of cells: cuboidal, columnar, and squamous cells, showing all forms of epithelial growth. (Dorland, 27th ed)

A dental specialty concerned with pathology of the oral cavity.
