Abstract
BACKGROUND

Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer with high incidence in older and immunocompromised patients. Its occurrence in the nasal dorsum is extremely rare and poses significant diagnostic and therapeutic challenges.

CASE SUMMARY

We report the case of a 65-year-old woman with diabetes mellitus and hypertension who presented with a dorsal nasal mass. The initial differential diagnosis favored hemangioma-based clinical examination on imaging. Histopathological examination after excision revealed MCC, necessitating a complex management strategy. A 3 cm × 2 cm nasal mass, initially suspected to be a hemangioma, was excised but revealed MCC with positive margins. Positron emission tomography–computed tomography confirmed metastatic cervical lymphadenopathy. The patient underwent bilateral neck dissection, revealing metastases in seven nodes. Residual activity was treated with radiation therapy, leading to a favorable response after 6 months.

CONCLUSION

This case highlights the importance of considering MCC in the differential diagnosis of nasal masses, and integrated management.

Core Tip: Merkel cell carcinoma (MCC) is a rare, aggressive neuroendocrine skin cancer often misdiagnosed owing to its non-specific presentation. This case report details the diagnostic and therapeutic challenges of MCC in the nasal dorsum of a patient with diabetes and hypertension. Emphasizing multidisciplinary collaboration, it highlights the role of advanced imaging, histopathological analysis, and tailored treatment strategies. By sharing insights from a unique clinical scenario, this report adds to the growing body of literature on MCC and underscores the importance of early recognition and comprehensive care in managing atypical presentations of this malignancy.
