AI Article Synopsis
- Alveolar soft-part sarcomas are unique soft-tissue tumors with unclear origins, commonly found in the head and neck regions, particularly in the orbit and tongue.
- A case study highlights a 28-year-old female with a sarcoma in her left masseter, presenting with chronic pain and numbness in her left lower lip.
- Imaging revealed a distinct mass, and a biopsy confirmed the tumor's characteristics, showing positive markers for myoglobin, actin, and desmin, which are important for diagnosis.
Article Abstract
Alveolar soft-part sarcomas are clinically and morphologically distinct soft-tissue sarcomas, with an unknown histogenesis. When the tumors affect the region of the head and neck, they are often located in the orbit and tongue. We report a case of an alveolar soft-part sarcoma in the left masseter of a 28-year-old female. The patient had chronic pain and paresthesia of her left lower lip. Panoramic radiography and computed tomography showed a well-delimited radiolucent mass in the left ramus. An incisional biopsy was performed, and the sample submitted for histopathological study. The tumor showed positive periodic acid-Schiff diastase-resistant granules. Immunohistochemically, the tumor cells were diffusely positive for myoglobin, and focally positive for actin and desmin.
