Sebaceous hyperplasia
Sebaceous hyperplasia is a skin condition. It forms non-malignant lesions, typically found in middle-aged individuals.[1] They are filled with sebum and can turn into a sebaceous tumor if left untreated. Sebum will typically come out of the lesion if squeezed. Sometimes this might hurt the person who has it.
