ReferencesSteatocystoma multiplex (SM), også kendt som steatocystomatosis eller epidermal polycystisk sygdom, er en sjælden, godartet hudlidelse, der er karakteriseret ved flere intradermale talgcyster i varierende størrelse. Klinisk fremstår SM som talrige, glatte, faste og bevægelige cystiske knopper og klumper, ofte uden symptomer. Læsionerne er typisk runde og ensartede i størrelse, fra nogle få millimeter til flere centimeter. Overfladen kan have en gullig nuance, mens de dybere cystere som regel matcher hudfarven. Væsken i cysterne er normalt lugtfri og olieagtig, med varierende grader af klarhed og farve. I modsætning til almindelige cyster er der som regel ingen synlig åbning i huden over cysten. SM kan forekomme overalt på kroppen, men er mest almindelig i områder med mange oliekirtler og hårsække, såsom torso, nakke, hovedbund, armhuler, arme, ben og lyske.
Steatocystoma multiplex (SM, also known as steatocystomatosis, sebocystomatosis, or epidermal polycystic disease) is a rare benign intradermal true sebaceous cyst of various sizes. Clinically, SM presents as asymptomatic, numerous, round, smooth, firm, mobile, cystic papules, and nodules. The lesions are uniform, with a size of a few millimeters to centimeters along the long axis. The superficial lesions are yellowish, and deeper lesions tend to be skin-colored. The fluid in SM is odorless, oily, clear or opaque, milky or yellow. The overlying epidermal skin is often normal, with no central punctum. SM can occur anywhere in the body but is more frequently seen in areas rich in pilosebaceous units such as the trunk (especially the presternal region), neck, scalp, axilla, proximal extremities, and inguinal region.

En 25‑årig mand kom ind med en hudlidelse på arme, bryst og mave. Han havde haft smertefri knuder i 20 år, som først optrådte på brystet og spredte sig til armene i løbet af de sidste 7 år.

Begyndelsen i puberteten skyldes formodentlig hormonstimulering af de pilosebaceous enheder. De opstår oftest på brystet, men kan også forekomme på maven, overarmene, armhulerne og ansigtet. I nogle tilfælde kan cyster udvikle sig over hele kroppen.
