Alveolar Soft Part Sarcoma (17): A variety of sarcoma having a reticulated fibrous stroma enclosing groups of sarcoma cells, which resemble epithelial cells and are enclosed in alveoli walled with connective tissue. It is a rare tumor, usually occurring between 15 and 35 years of age. It appears in the muscles of the extremities in adults and most commonly in the head and neck region of children. Though slow-growing, it commonly metastasizes to the lungs, brain, bones, and lymph nodes.

Granular Cell Tumor (5): Unusual tumor affecting any site of the body, but most often encountered in the head and neck. Considerable debate has surrounded the histogenesis of this neoplasm; however, it is considered to be a myoblastoma of, usually, a benign nature. It affects women more often than men. When it develops beneath the epidermis or mucous membrane, it can lead to proliferation of the squamous cells and mimic squamous cell carcinoma. OCOSH Code C04.557.450.590.350_BD_BN_CTS_MT_GC
