Merkel cell carcinoma.

Area of Science:

• Oncology
• Dermatology
• Pathology

Background:

• Merkel cell carcinoma (MCC) is an uncommon but aggressive neuroendocrine skin cancer.
• MCC exhibits a high potential for metastasis, particularly in older individuals with sun-exposed skin lesions.

Purpose of the Study:

• To outline the diagnostic and management strategies for Merkel cell carcinoma.
• To emphasize the importance of early recognition and specialized care for MCC patients.

Main Methods:

• Diagnosis involves integrating patient history, clinical presentation, radiological imaging, and pathological examination.
• Treatment recommendations include prompt surgical excision with a 1-2 cm margin and simultaneous sentinel-node biopsy.
• Adjuvant radiation therapy may be considered for the tumor site.

Main Results:

• Suspicion should arise from rapidly growing, non-tender cutaneous tumors on sun-exposed areas in older patients.
• Multidisciplinary findings are essential for accurate diagnosis.
• Timely surgical intervention and sentinel-node biopsy are critical.

Conclusions:

• Merkel cell carcinoma requires a high index of suspicion and prompt, specialized management.
• Integrated diagnostic approaches and timely, aggressive treatment are key to improving outcomes.
• Care should be centralized in experienced medical facilities.
