Abstract:
Solitary fibrous tumors are an uncommon slow growing benign neoplasm originally described as a pleural neoplasm but can also be found in the lung, mediastinum, peritoneum, or any other sites including the head and neck. Malignant solitary fibrous tumors (MSFT) are extremely rare and only few cases have been published in the literature. There have been 19 cases reported of MSFT in the head and neck, but there are no reports of MSFT located within the scalp in the English language literature. We present a case of MSFT arising in the scalp and describe our experience with the clinical presentation, surgical management, and outcome in this pathological condition.
Insights
Malignant solitary fibrous tumors (MSFT) are rare, with no prior English reports in the scalp. This case details the first scalp MSFT, covering its presentation, surgical treatment, and outcome.
Area of Science:
- Oncology
- Pathology
Background:
- Solitary fibrous tumors (SFT) are uncommon, slow-growing neoplasms.
- While typically pleural, SFTs can occur in various extrathoracic locations, including the head and neck.
- Malignant solitary fibrous tumors (MSFT) are exceptionally rare.
Observation:
- This report details the first documented case of a malignant solitary fibrous tumor (MSFT) arising in the scalp.
- The case includes observations on the clinical presentation of this rare scalp neoplasm.
Findings:
- The study presents a unique case of MSFT in the scalp, a location not previously reported in English literature.
- It details the surgical management strategies employed for this rare condition.
Implications:
- This case expands the known anatomical distribution of malignant solitary fibrous tumors.
- It provides valuable insights into the clinical course and surgical treatment of MSFT in the scalp for future reference.
