Sebaceous gland extrusion

The extrusion of a sebaceous gland through a follicular infundibulum is a rare dermatopathology image that raises two fundamental questions: Is it an artifact?. Can a full gland be expelled just as its secretion does?. The answer is not easy and there are no bibliographic references to help us solving the doubt. These two images correspond to the case of an 18-year-old male patient who consulted for a rapidly evolving yellowish nummular lesion on the cheek. An oily secretion was released from it. The patient denied manipulation of the lesion. With the clinical judgment of sebaceous gland hyperplasia, the lesion was excised. The presence of an extruded sebaceous gland was the only histological finding (Figures 1,2). Excision was curative.
