Pedunculated malignant melanoma

Insights

A rare pedunculated malignant melanoma presented aggressively with erosion and bleeding. Despite localized tumor cells, it had already metastasized to lymph nodes.

Area of Science:

  • Dermatology
  • Oncology
  • Pathology

Background:

  • Primary malignant melanoma can present in rare forms.
  • Pedunculated presentation is uncommon for melanoma.

Observation:

  • A case of a woman with a primary pedunculated malignant melanoma was observed.
  • The lesion exhibited erosion and bleeding, suggesting aggressive behavior.
  • Differential diagnoses included seborrheic keratosis, fibroepithelial papilloma, and pyogenic granuloma.

Findings:

  • Tumor cells were confined to the pedunculated mass.
  • Metastasis to regional lymph nodes was confirmed at surgery.

Implications:

  • This rare presentation can lead to diagnostic challenges.
  • Early metastasis highlights the aggressive potential of such lesions.
  • Prompt diagnosis and treatment are crucial for pedunculated malignant melanoma.
