Summary
Merkel cell carcinoma (MCC), a rare neuroendocrine cancer, requires early diagnosis. This case report details facial MCC, highlighting clinical, histopathological, and dermoscopic features for improved identification of this rare tumor.
Area of Science:
- Dermatology
- Oncology
- Pathology
Background:
- Merkel cell carcinoma (MCC) is a rare, aggressive neuroendocrine skin cancer.
- Known risk factors necessitate early diagnosis and prompt treatment.
- Facial presentation of MCC requires careful clinical and diagnostic evaluation.
Observation:
- An 82-year-old woman presented with a facial Merkel cell carcinoma.
- Clinical and histopathological characteristics of the tumor were documented.
- Dermoscopic examination revealed specific vascular patterns and milky-red areas.
Findings:
- The case highlights the importance of dermoscopy in diagnosing rare skin cancers.
- Atypical vascular patterns and milky-red areas are key dermoscopic clues for MCC.
- Differential diagnosis considerations for facial nodules are discussed.
Implications:
- Enhanced understanding of MCC dermoscopy aids in early and accurate diagnosis.
- This case contributes to the literature on the morphologic presentation of MCC.
- Improved diagnostic criteria can lead to more timely and effective treatment strategies for Merkel cell carcinoma.
