Area of Science:

  • Oncology
  • Radiotherapy
  • Oral Medicine

Background:

  • External beam radiotherapy for head and neck malignancies can cause adverse oral effects.
  • Oral and salivary tissues are susceptible to damage when within the radiation field.

Observation:

  • A patient presented with widespread oral melanotic hyperpigmentation.
  • This condition developed following radiotherapy for metastatic cervical lymph node carcinoma.

Findings:

  • The observed oral melanotic hyperpigmentation is a potential adverse effect of radiotherapy.
  • This represents a previously undescribed consequence of radiation treatment, specifically oral melanotic macules.

Implications:

  • Highlights a novel side effect of radiotherapy in head and neck cancer patients.

  • Suggests the need for increased awareness and monitoring of oral tissues post-radiation.
  • May inform future treatment planning and patient counseling regarding radiotherapy side effects.
