This case report details a rare subcutaneous leiomyosarcoma that developed in radiation dermatitis. This finding is novel, as no prior instances of this specific cancer arising in radiation-affected skin have been documented.

Area of Science:

  • Oncology
  • Dermatology
  • Pathology

Background:

  • Radiation dermatitis is a known complication of radiotherapy.
  • Leiomyosarcomas are malignant tumors arising from smooth muscle tissue.

Observation:

  • A 59-year-old patient presented with slow-growing nodules in an area of chronic radiation dermatitis.
  • The dermatitis resulted from radiotherapy for a mediastinal tumor treated 34 years prior.

Findings:

  • Histopathological examination confirmed the nodules as subcutaneous leiomyosarcoma.
  • This represents the first reported case of leiomyosarcoma developing within radiation dermatitis.

Implications:

  • Highlights a potential long-term complication of radiotherapy, emphasizing the need for vigilant monitoring of radiation dermatitis.
