Sebaceous adenoma
Synopsis

Sebaceous adenomas are most commonly found on the head and neck, which is where sebaceous glands are particularly abundant. Rarely, they may present on other hair-bearing areas of the body, including the trunk and the legs. There are also rare reports of lesions on the oral mucosa.
Although considered rare, the actual incidence of sebaceous adenomas is unknown. There is no racial predilection or increased incidence in a particular geographical location. Sebaceous adenomas frequently appear after the age of 50, with an average age of onset of 60. They typically affect men and women equally. These benign neoplasms do not have the potential for aggressive growth or metastasis, although local recurrence may occur after incomplete removal of the tumor.
The presence of a sebaceous adenoma can be concerning for possible underlying visceral malignancies, usually of the gastrointestinal tract, due to its association with Muir-Torre syndrome (MTS).
