Papular acne scars. A common cutaneous finding.

PMID: 2140672  

One hundred thirty-three patients were examined for the presence of a cutaneous eruption consisting of small, asymptomatic, hypopigmented, follicular papules on the upper part of the trunk. The papules were present in 57% of patients who had a history of acne vulgaris and in 9% of patients who denied ever having had acne. Biopsy specimens from five patients revealed circumscribed, perifollicular or parafollicular lesions in which both elastic and collagen fibers were attenuated in comparison with those in normal adjacent dermis. These changes are consistent with scar. We conclude that the papules are a scarring process secondary to acne vulgaris and propose calling the lesions papular acne scars. They appear closely related to or identical with changes previously termed perifollicular elastolysis, postacne anetoderma-like scars, and papular elastorrhexis.

Longer TA repeat but not V89L polymorphisms in the SRD5A2 gene may confer acne risk in the Chinese population.

DOI: ada.2018.73162  PMCID: PMC5872244  PMID: 29610568   Several studies have reported that the V89L and TA repeat polymorphisms [(TA)n] of the SRD5A2 gene were associated with SRD5A2 activity. The activity of dihydrotestosterone, which is converted from testosterone by SRD5A2, is responsible for sebum secretion and the formation of acne. We hypothesized that abnormalities in SRD5A2 action could contribute …
