sebaceous adenoma

particularly common in the skin of aged dogs. On the eyelids they arise from the meibomian glands.

sebaceous cyst

a benign retention cyst containing sebum.

sebaceous epithelioma

basal cell tumor with sebaceous differentiation.

sebaceous gland

holocrine glands in the skin that secrete sebum usually through the hair follicles. They vary in size and activity between species and location. In dogs, large sebaceous glands are located on the dorsum of the tail (see tail gland) and at mucocutaneous junctions. In cats, large glands are located also on the dorsum of the tail, on the lip margins and under the chin (see submental organ).

sebaceous gland secretion abnormality

includes sebolith, seborrhea.
