Cysts may be related to high levels of testosterone, hence may be more frequent in users of anabolic steroids. [5] A case has been reported of a sebaceous cyst being caused by the human botfly. [6] Hereditary causes of sebaceous cysts include Gardner's syndrome and basal cell nevus syndrome.
Trichilemmal cysts may be classified as sebaceous cysts, [6] although technically speaking are not sebaceous. [7] "True" sebaceous cysts, which originate from sebaceous glands and which contain sebum, are relatively rare and are known as steatocystoma simplex or, if multiple, as steatocystoma multiplex. Medical professionals have suggested that ...
Epidermoid cyst may be classified as a sebaceous cyst, [15] although technically speaking it is not sebaceous. [16] "True" sebaceous cysts, cysts which originate from sebaceous glands and which contain sebum, are relatively rare and are known as steatocystoma simplex or, if multiple, as steatocystoma multiplex. Medical professionals have ...
Relative incidence of cutaneous cysts. Steatocystoma is labeled at right. Steatocystoma simplex is a skin condition characterized by a skin lesion that occurs with equal frequency in adult women and men, and is typically found on the face, trunk, or extremities. [1]: 679 It is related to Steatocystoma multiplex. [2]
Sebaceous glands are uncommon on the soles of the feet and the palms of the hand, and accordingly, so are sebaceous cysts vanishingly rare in those areas—sufficiently rare that the diagnosis of such a thing might be worth the publication of a letter in a dermatologic journal.
The cysts can be removed via excision, though conventional cyst excision techniques have proven impractical, and a specialized regimen is required. [5] Cryotherapy and electrodessication may also be tried, but since it is a genetic disorder all the modalities have very little effect. Individual cysts can be removed surgically.
Within the latter type, hairs in structures called pilosebaceous units have a hair follicle, sebaceous gland, and associated arrector pili muscle. [17] In the embryo, the epidermis, hair, and glands are from the ectoderm, which is chemically influenced by the underlying mesoderm that forms the dermis and subcutaneous tissues. [18] [19] [20]
