Summary
Deep soft tissue leiomyomas (DSTL) are rare tumors. This study details two cases, highlighting their uncertain prognosis and potential for metastasis despite benign morphology.
Area of Science:
- Oncology
- Pathology
- Surgical Pathology
Context:
- Deep soft tissue leiomyomas (DSTL) are exceptionally rare.
- Limited histological and clinical data exist, particularly concerning their malignant potential.
- Accurate characterization is crucial for patient management and prognosis.
Purpose:
- To present two unique cases of deep soft tissue leiomyomas.
- To detail their histological, immunohistochemical, and clinical characteristics.
- To discuss the diagnostic challenges and prognostic implications of DSTL.
Summary:
- Two DSTL cases in women (43 and 63 years) from head and perineum regions are described.
- Morphological features included good borderline, fibrous pseudocapsule, and classical leiomyoma appearance, with dystrophic calcification or myxohyaline degeneration.
- Immunohistochemistry confirmed smooth muscle origin (actin, desmin positive; S-100 negative). One case showed recurrence after 5 years.
Impact:
- This report contributes valuable data on rare DSTL, aiding in their diagnosis and classification.
- Highlights the potential for metastasis despite benign histological features, emphasizing the need for vigilant follow-up.
- Informs clinical decision-making and prognostic assessment for patients with DSTL.
