Merkel Cell Carcinoma: A Case Series

Area of Science:

• Oncology
• Dermatology
• Surgical Oncology

Background:

• Merkel cell carcinoma (MCC) is a rare cutaneous malignancy known for its aggressive nature and high metastatic potential.
• Early detection and prompt management are crucial for improving patient outcomes in MCC.
• Understanding the clinical behavior and treatment responses in MCC is essential for refining therapeutic strategies.

Observation:

• Three male patients with MCC presented with cutaneous lesions on the thorax, buttock, and forearm.
• Management involved wide local excision, lymph node dissection, and adjuvant radiotherapy.
• Outcomes varied, with one patient in remission, one with residual disease, and one with distant metastasis who deceased.

Findings:

• The case series illustrates the diverse clinical presentations and treatment pathways for Merkel cell carcinoma.
• Adjuvant radiotherapy following surgical resection is a key component of MCC management.
• Patient prognosis in MCC is significantly influenced by the stage at diagnosis and the presence of metastasis.

Implications:

• This series underscores the complexity of MCC management and the need for standardized treatment protocols.
• Establishing local or national databases for MCC patients is vital for improved monitoring and research.
• Further research into MCC's aggressive behavior and metastatic potential is warranted to develop more effective therapies.
