Abstract:
A woman had a primary pedunculated malignant melanoma. This is a rare form of presentation and may result in clinical confusion with seborrheic keratosis, fibroepithelial papilloma, or granuloma pyogenicum. The aggressive nature of the lesion was indicated by the presence of erosion and bleeding. Though the tumor cells were present only in the pedunculated mass, it had metastasized to regional lymph nodes at the time of surgery.
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.
