EtiopathogenesisThis section has been translated automatically.
These are sebaceous gland complexes without hair follicles. They can be idiopathically dislocated but also occur in the context of exfoliative inflammation (e.g. in Stevens-Johnson syndrome). Occasionally eruptive ectopic sebaceous glands are observed in colon cancer (Lynch syndrome) (De Felice C et al. 2005). They have also been described in connection with Muir-Torre syndrome (Ponti G et al. 2015).
LocalizationThis section has been translated automatically.
V.a. localized at the edge of the labial red, anal funnel, glans penis ( Tyson glands), large labia and eyelids.
Not infrequently, ectopic sebaceous glands are also found in the esophagus.
The Montgomery g lands, which are arranged circularly in the areolae mammae, are erroneously included among the ectopic sebaceous glands because of their clinical aspect, since histologically they have glands comparable to an accessory nipple.
Clinical featuresThis section has been translated automatically.
Harmless, mostly multiple, up to 0.1 cm large, isolated but also aggregated to smaller beds, completely symptom-free, yellow to yellow-white, mostly hardly, occasionally also granularly palpable, reactionless nodules. On the lips the sebaceous glands are very often found in the skin-near area of the lip red, on the commissures and on the inside. Puberty seems to stimulate their appearance. Patients should be convinced of the harmlessness of the findings (see rare exceptions).
