Sebaceous cyst. A sebaceous cyst is a term commonly used to refer to either: [ 1] Both of the above types of cysts contain keratin, not sebum, and neither originates from sebaceous glands. Epidermoid cysts originate in the epidermis and pilar cysts originate from hair follicles. Technically speaking, then, they are not sebaceous cysts. [ 2] ".

Steatocystoma multiplex, is a benign, autosomal dominant congenital condition resulting in multiple cysts on a person's body.

Epidermoid cyst. Relative incidence of cutaneous cysts, where epidermoid cysts constitute a plurality (blue area). An epidermoid cyst or epidermal inclusion cyst[ 1] is a benign cyst usually found on the skin. The cyst develops out of ectodermal tissue. Histologically, it is made of a thin layer of squamous epithelium .
A sebaceous gland or oil gland[ 1] is a microscopic exocrine gland in the skin that opens into a hair follicle to secrete an oily or waxy matter, called sebum, which lubricates the hair and skin of mammals. [ 2] In humans, sebaceous glands occur in the greatest number on the face and scalp, but also on all parts of the skin except the palms of ...

Trichilemmal cysts are clinically and histologically distinct from trichilemmal horns, hard tissue that is much rarer and not ...
Sebaceous hyperplasia is a disorder of the sebaceous glands in which they become enlarged, producing flesh-colored or yellowish, shiny, often umbilicated bumps. [ 1] Sebaceous hyperplasia, primarily affecting older patients in high-concentration areas like the face, head, and neck, typically has a 2-4 mm diameter and causes no symptoms.
Sebaceous carcinoma is a neoplastic growth of sebaceous glands. It is predominantly seen in the head and neck region given the high density of sebaceous glands in this region. The periocular region, which includes the meibomian, Zeis, and sebaceous glands of the caruncle and eyelid, is the most common site accounting for up to 75% of SGc. [ 6]
Cock's peculiar tumour is a sebaceous cyst linked growth that can resemble a squamous cell carcinoma. [1] The name is given after a 19th-century English surgeon Edward Cock. [2] The proliferating cyst is usually solitary, but it often arises from a simple trichilemmal cysts in the hair follicle epithelium and these are multiple in 70% of cases.
