  • Cutaneous adnexal tumors are a group of skin tumors consisting of tissues that have differentiated (i.e. matured from stem cells) towards one of the four primary adnexal structures found in normal skin: hair follicles, sebaceous sweat glands, apocrine sweat glands, and eccrine sweat glands. (wikipedia.org)
  • However, more recent studies have found them to be hair follicle tumors and commonly term them spiradenomas and spiradenocarcinomas, respectively. (wikipedia.org)
  • Further confusing the situation, SA-like and SAC-like tumors are also 1) manifestations of the inherited disorder, CYLD cutaneous syndrome (CCS), and 2) have repeatedly been confused with an entirely different tumor, adenoid cystic carcinomas of the salivary gland. (wikipedia.org)
  • Here, SA and SAC are strictly defined as sporadic hair follicle tumors that do not include the hereditary CCS spiradenomas and heridtary spiradenocarcinoms of CCS or the adenoid cystic carcinomas. (wikipedia.org)

  • Sebaceous glands, or holocrine glands, secrete sebum, which serves to lubricate the skin and make it more impervious to moisture. (medscape.com)
  • Sebaceous glands secrete SEBUM. (wakehealth.edu)
  • The major salivary glands are in close relation with oral cavity structures, although they are not part of the oral cavity. (medscape.com)
  • The glands deposit sebum on the hairs, and bring it to the skin surface along the hair shaft. (wikidoc.org)
  • Here, the sebum traverses ducts which terminate in '''sweat pores''' on the surface of the skin. (wikidoc.org)
  • Sebum is one cause of some people experiencing "oily" hair if it is not washed for several days. (wikidoc.org)
  • Sebum acts to protect and waterproof [[hair]] and skin, and keep them from becoming dry, brittle, and cracked. (wikidoc.org)
  • The prescription drug [[isotretinoin]] significantly reduces the amount of sebum produced by the sebaceous glands, and is used to treat acne. (wikidoc.org)
  • Importance to other animals== Certain species of [[Demodex mite]]s feed on sebum and are commonly found in the sebaceous glands of mammals, including those of humans. (wikidoc.org)
  • The normal function of these glands is to produce sweat, which cools the body via evaporation. (medscape.com)
