Superficial leiomyosarcoma, a rare soft tissue tumor, can occur in the head and neck. This case report details a successful postauricular leiomyosarcoma excision with no recurrence at 26 months.

Area of Science:

  • Oncology
  • Pathology
  • Surgical Oncology

Background:

  • Superficial leiomyosarcomas are uncommon soft tissue neoplasms, typically affecting the lower extremities.
  • Their occurrence in the head and neck region is exceptionally rare, often leading to diagnostic challenges and delays.

Observation:

  • A case of a 46-year-old male presenting with a postauricular leiomyosarcoma is described.
  • The tumor was completely resected with wide surgical margins (3 cm).

Findings:

  • Immunohistochemical analysis confirmed the leiomyosarcoma diagnosis, showing positive staining for smooth muscle actin, vimentin, and desmin.
  • The patient experienced an uncomplicated postoperative recovery and remained disease-free at a 26-month follow-up.

Implications:

  • Accurate histological diagnosis through immunohistopathology is crucial for superficial leiomyosarcoma.
  • Ear, Nose, and Throat (ENT) surgeons must consider superficial leiomyosarcoma in the differential diagnosis of head and neck lesions due to its distinct clinical behavior and management requirements.
