Synonym(s): Basal cell epithelioma Basaloma

Contributor(s): William Brewer Jr, Irene Rochlitz, David Scarff

Introduction

  • Cause: common epithelial neoplasm
    • Benign (usually): well circumscribed, ulcerated Neoplasia: basal cell carcinoma nose .
    • Malignant (rarely): poorly circumscribed with scirrhous response.
  • Frequently on head and neck, thorax and back.
  • Diagnosis: histopathology.
  • Treatment: surgical excision. Radiotherapy for extensive malignant lesion.
  • Prognosis: good.

Pathogenesis

Etiology

  • Unknown, but not related to exposure to bright sunlight as in man.

Pathophysiology

  • Tumor arises from basal epithelium.
  • Histologically appear aggressive, with high mitotic rate, but are benign tumors.
  • Very occasionally metastasize to local lymph node.
  • Arise from basal cells epidermis, sebaceous gland, sweat gland, hair follicle.

Timecourse

  • Slow growing (weeks to months).
