Summary Folliculosebaceous cystic hamartoma (FSCH) is a rare cutaneous hamartoma composed of dilated folliculosebaceous units associated with mesenchymal elements. Two cases of FSCH with typical histopathological features are reported. Patient 1 was a 60‐year‐old man presented with a normal skin‐coloured asymptomatic nodule on his scalp. Patient 2 was a 70‐year‐old man with an asymptomatic nodule on his right auricle that had persisted for the previous 15 years. In all, 34 cases of FSCH have been reported in the English literature. Clinically, the lesions are asymptomatic, usually rubbery to firm in consistency, and usually occur on or above the neck (> 90%). Most lesions do not exceed 25 mm in diameter (> 90%). Histopathologically, FSCH shares several similar features to sebaceous trichofolliculoma, but it is usually possible to differentiate these two tumours.
