A case of a low-grade mucoepidermoid tumour showing an unusual pattern of extensive central keloid-like sclerosis is reported. The sparsity of tumour islands renders recognition of its neoplastic nature difficult. It is postulated that the sclerosis results from exaggerated post-inflammatory scarring due to extravasation of mucin from the tumour into the stroma.
