Nodular BCC

Causes/Factors

The primary cause is prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds. Other risk factors include:

  • Fair Skin: Light-skinned individuals are more susceptible.
  • Chronic Sun Exposure: Especially without adequate sun protection.
  • History of Skin Cancer: Previous BCCs or other skin cancers increase the risk.
  • Immunosuppression: Weakened immune system due to conditions or medications.
  • Age: BCC is more common in older adults.

Symptoms

  • Nodular BCC: typically a pearly nodule with rolled edge on face or sun-exposed site. May have a central ulcer
  • Superficial BCC: lesions appear as red scaly plaques with raised smooth edge. Often on trunk or shoulders.

Diagnostic Tests

  • Referral to a dermatologist for input
  • Skin biopsy

Management

  • Excision
  • Cryotherapy
  • For topical BCC: flurouracil (efudex) or imiquimod

Complications/red Flags

  • Local Tissue Destruction: If left untreated, BCC can invade surrounding tissues and structures.
  • Disfigurement: Lesions on the face can cause disfigurement if not properly treated.
  • Recurrence: BCCs may recur, especially if not completely removed.
