Merkel Cell Carcinoma Occurring Within A Squamous Papilloma of the External Ear Canal - A Case of Spontaneous Regression

Abstract

Merkel Cell Carcinoma (MCC) is a rare, malignant neuroendocrine tumour belonging to the broad category of cancers called small round blue cell tumours. We present a case of this rare tumour occurring in a squamous papilloma of the external auditory canal of a patient, which regressed spontaneously and was subsequently excised with no evidence of recurrence.
