Summary
Alveolar soft-part sarcoma (ASPS) is a rare tumor. This case highlights the first reported instance of ASPS metastasizing to the liver in Nigeria, emphasizing the need for early diagnosis and treatment.
Area of Science:
- Oncology
- Pathology
Background:
- Alveolar soft-part sarcoma (ASPS) is a rare, slow-growing malignancy.
- ASPS commonly metastasizes to the lungs, bones, lymph nodes, and brain.
- Liver metastasis from ASPS is exceptionally rare, with this being the first reported case in Nigeria.
Purpose of the Study:
- To report the first case of alveolar soft-part sarcoma with liver metastasis in Nigeria.
- To highlight the diagnostic challenges and clinical presentation of ASPS in the African region.
- To emphasize the importance of early diagnosis and prompt surgical intervention for ASPS with metastasis.
Main Methods:
- Case report of a 57-year-old male patient.
- Clinical presentation of a persistent left calf mass.
- Initial diagnosis as soft-tissue sarcoma, with subsequent death prior to histological confirmation.
Main Results:
- The patient presented with a calf mass suggestive of soft-tissue sarcoma.
- Systemic effects of the tumor led to the patient's demise.
- The case represents the first documented instance of liver metastasis from ASPS in Nigeria.
Conclusions:
- Alveolar soft-part sarcoma can metastasize to the liver in Northeast Africa.
- A high index of suspicion is crucial for early diagnosis of ASPS.
- Prompt surgical excision with clear margins is essential to prevent mortality.
