Case Report

Cylindroma - a case report: benign but not banal!


A Pavli, S Lee 李啟焱, S Mann


The diagnosis of cylindroma can be challenging due to the rarity of the tumour and its broad differential diagnosis. We present a case report of a solitary benign cylindroma on the right scalp of a 51-year-old patient which was initially thought to be a basaloid follicular hamartoma based on biopsy. We outline the differential diagnosis of cylindroma, as well as the histopathological features and the pathological differences between cylindroma and basaloid follicular hamartoma. The ethical dilemmas surrounding the management of benign solitary cylindromas, including the potential for malignant transformation, risks associated with operating, and cost for the patient, are also discussed.
