Abstract

Merkel cell carcinoma is an aggressive non-melanomatous cutaneous tumour of neuroendocrine origin with an increasing incidence in the recent years. It is a tumour of the elderly and immunosuppressed, which most often appears on sun-exposed areas of the body. The clinical features of the cutaneous or subcutaneous lesions hardly contribute to the diagnosis, and, hence, histopathology and immunohistochemistry play a vital role in diagnosis. The latest staging system by the American Joint Committee on Cancer includes non-nodal invasion to adjacent structures i.e. bone, muscle, fascia, or cartilage into the criteria, in additionto size and depth of invasion. The management reliesheavily on a multidisciplinary approach due to rarity of incidence of this disease. According to the international guidelines, surgical management is still the preferred choice. The beneficial role of adjuvant radiotherapy has now been more clearly documented. Data is insufficient to assess whether chemotherapy improves disease-free or overall survival.
