Reconstruction of Rapidly Growing Merkel Cell Carcinoma of the Cheek With Multidisciplinary Cooperation

초록

Merkel cell carcinoma (MCC) is a rare and very aggressive skin cancer. An 83-year-old female presented with a 1.5 cm-sized non-tender mass on her left cheek and was diagnosed with MCC. The margin of MCC was well-defined and there was no cervical node metastasis on pre-operative computed tomography. Three weeks after the first visit, the mass rapidly increased in size. We checked the magnetic resonance imaging, a rapid-growing 2.5 cm sized nodular region and metastatic cervical lymph node were found. We performed wide excision of the MCC and neck lymph need dissection with multidisciplinary cooperation. The soft tissue defect was about 6.0x5.0 cm(2) in size and reconstructed with radial forearm free flap. On permanent biopsy, the size of MCC was 3.0x2.3 cm(2). There was no recurrence of MCC with radiation therapy during an 18-month follow-up. We experienced an older patient with a rapid-growing MCC and cervical lymph node metastasis in a brief time. With our experience, we discuss the evaluation and treatment plan of the rapid-growing MCC for good results.
