Background/objectives: Acne vulgaris (AV) is the common form of acne, characterized by a polymorphic eruption of inflammatory non-papules, pustules, nodules, blackheads, and whiteheads. Acne was eighth among the top 10 disorders in terms of prevalence in 2010. The objective of this study was to see if there was any association between acne vulgaris and BMI in the young adult population.Methods: This is a single-center retrospective study conducted at King Abdulaziz Medical City, Riyadh, Saudi Arabia. Adult patients diagnosed with acne vulgaris from January 2017 to June 2022 were enrolled. The estimated sample size was reached using consecutive, non-probability sampling.Results: A total of 596 participants were selected as a match to the criteria of the research objectives. Of the participants, slightly more than half were males (52.5%) and the rest were females (47.5%). There was a nearly equal number of cases and controls, around 48.7% of the patients had acne while the rest did not. The majority were of the age group 18 to 19 years followed by 22 to 23 years (25.2%). A majority had a normal BMI of 18.5 to 24.9 (40.4%). A significant difference was found between the means of the BMI of the participants who had acne and those who did not (p<0.05). Conclusion:No significant association was found between age group, gender, BMI, and acne. To fully comprehend how dietary factors affect the severity of acne, more studies are required.

The distribution of lentigines offers great insight into the multitude of potential-associated genetic or acquired conditions. In this report, we described a unique presentation of lentigines limited to the palms and soles in a healthy individual. Personal and familial history, clinical examination, serological testing, and whole-genome sequencing were all unremarkable. The benign clinical features and absence of associated medical conditions support the likely lentigo simplex with an isolated palmoplantar distribution. To date, no similar distribution has been reported. This case extends the breadth of view into all possible presentations of lentigines.
