Summary
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.
