Basaloid follicular hamartoma (BFH) is a rare benign follicular tumor with varied clinical presentation. A 64-year-old male presented with a gradually enlarging plaque on the scalp of 10 years duration, the surface of which showed a unique cobblestone like appearance and dilated follicular openings discharging keratinous material. Histology was initially reported as trichofolliculoma. As the clinical picture was not suggestive of trichofolliculoma, the histopathology was reviewed. A final diagnosis of BFH was made based on the characteristic features such as distorted hair follicles with peripheral extensions of basaloid cells in a branching and anastomosing pattern. A periodic follow-up of such lesions is essential due to the risk of malignant transformation to basal cell carcinoma.
