Acne medicamentosa
medical condition
Acne medicamentosa is acne that is caused or aggravated by medication. Because acne is generally a disorder of the pilosebaceous units caused by hormones, the medications that trigger acne medicamentosa most frequently are hormone analogs. It is also often caused by corticosteroids; in this case, it is referred to as steroid acne.
Although the masculinizing hormone testosterone is most often blamed, and although men with acne secondary to bodybuilding hormones are seen from time to time, the major hormonal medications that cause acne are the progestin analogues present in hormonal contraception. Other medications can produce acneiform eruptions (usually pimply bumps and pustules that look like acne).
Some conditions mimic acne medicamentosa. The most common mimic is folliculitis produced by an overgrowth of the Malassezia species, often secondary to oral or systemic corticosteroids, or secondary to broad-spectrum antibiotics such as the tetracycline family used in acne. This is often misinterpreted as 'tetracycline-resistant acne'.
Begin with the source’s own compact description: “Acne medicamentosa” is medical condition. The dossier treats that line as a proposition to test through Acne, medicamentosa and medical, not as a finished interpretation.
Why this record matters
The phrase “medical condition” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Nov 15, 2025. The linked authority identifier is Q4674429. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
