摘要

Soft-tissue sarcomas (STS) are rare tumors that account for 1% of all adult malignancies, with over 100 different histologic subtypes occurring predominately in the trunk, extremity, and retroperitoneum. Alveolar soft part sarcoma (ASPS) is a rare form of soft-tissue sarcoma arising from connective tissue. It is often seen in adolescents and young adults and has high propensity for recurrence and metastasis. Clinically, it mimics hemangioma or arteriovenous malformations.

In our case, a 23 year-old female presented with 2 months history of foreign body sensation in throat, muffled voice, dysphagia and occasional moderate amount of hemoptysis. Per oral examination revealed left tonsil vascular mass. Computer Tomography (CT) Neck revealed a vascular mass arising from left tonsillar fossa. Histopathology post surgical excision revealed the mass to be alveolar soft part sarcoma (ASPS). CT staging and Magnetic Resonance (MR) Neck 3 months following surgical excision showed no residual tumour or distant metastases.

The occurrence, radiological investigation and management of this disease is discussed.

We are reporting this first case of oropharynx alveolar soft part sarcoma in Malaysia due to rarity of its occurrence.
