The authors describe 10 cases of sebaceoma that manifested prominent infundibulocystic structures in all cases and, additionally, conspicuous squamous metaplasia in 6 neoplasms. All tumors occurred on the scalp or the face (2 cases lacked clinical information) and presented as a solitary lesion, measuring from 5 to 20 mm. The patients' age ranged from 22 to 89 years. The main component of all tumors was small, uniform basaloid cells (immature sebocytes) intermixed with mature sebocytes clearly arranged in nodules, classifying the lesi
