Subcutaneous leiomyosarcoma, a rare facial cancer, requires prompt recognition. Effective treatment involves wide surgical excision and potentially radiotherapy to prevent recurrence and metastasis.

Area of Science:

  • Dermatopathology
  • Surgical Oncology
  • Soft Tissue Sarcoma Research

Background:

  • Cutaneous leiomyosarcoma is a rare soft tissue malignancy.
  • Facial leiomyosarcoma is exceptionally uncommon.
  • Subcutaneous leiomyosarcoma exhibits a higher recurrence and metastasis rate compared to superficial dermal types.

Observation:

  • This case report details a rare instance of subcutaneous leiomyosarcoma on the face.
  • Histologic examination and immunohistochemical studies were performed.
  • The observed neoplasm demonstrated deep tumor invasion, high malignancy grade (3B), and significant size.

Findings:

  • Leiomyosarcoma of the face is exceedingly rare.
  • The deep subcutaneous variant is hypothesized to originate from vascular smooth muscle.

  • The reported case presented with aggressive features, necessitating wide excision and adjuvant radiotherapy.
  • Implications:

    • Dermatologic surgeons and pathologists must be aware of subcutaneous leiomyosarcoma characteristics.
    • Subcutaneous leiomyosarcoma has a greater propensity for recurrence and metastasis than superficial types.
    • Optimal treatment involves wide surgical excision (3-5 cm margins) including subcutaneous tissue and fascia, potentially combined with postoperative radiotherapy.
