    Abstract:
    Alveolar soft-part sarcoma (ASPS) is a rare malignant neoplasm with uncertain histogenesis and with a distinctive morphology. It has been described in the oral cavity, but this is the first report of ASPS metastasizing to the maxillary tuber region. A 27-year-old male patient, who was under chemotherapy treatment for ASPS of the thigh, presented in our dental clinic with a painless and pedunculated nodule on the right tuber maxillae. The nodule was erythematous with smooth and lobular surface, measuring 3 cm in maximum diameter. An incisional biopsy was performed and the diagnosis of metastatic ASPS was made. Histologically, the tumor was characterized by a proliferation of polyhedral cells in pseudoalveolar pattern. Tumor cells were large, showing granular cytoplasm, periodic acid-Schiff positive diastase-resistant intracytoplasmic material, and vesicular nuclei with prominent nucleoli. Unfortunately, the patient died 2 months after the diagnosis of the oral metastasis. Metastases of ASPS to the mouth are very rare and indicate a poor prognosis.
