Background: The detection rate of human papillomavirus (HPV) in Bowen's disease (BD) varies greatly., Objectives: To detect HPV DNA in BD samples using next-generation sequencing (NGS) and compare HPV detection rates between pelvic and non-pelvic BD., Materials and Methods: We evaluated 99 patients with BD in our institution. DNA was extracted from formalin-fixed and paraffin embedded (FFPE) tissue blocks. The presence of HPV DNA material was detected using special kit-based NGS technology. Clinical characteristics and HPV detection rates were then compared between pelvic and non-pelvic BD samples., Results: HPV was detected in 26 (26.3%) BD samples. A total of 10 types of α-HPV was detected: HPV 16, 53, 31, 58, 66, 26, 27, 57, 45, and 72. The most common HPV type was 16 (12.1%). Only two types (27 and 57) were frequently classified as cutaneous type, and the rest were mucosal types. The HPV detection rate was significantly higher in pelvic BD (45.2%) compared to non-pelvic BD (17.6%)., Conclusion: The present study suggests that sexually transmitted mucosal α-HPV plays a significant role in the pathogenesis of BD, especially in the pelvic region.

Atypical presentations of genital herpes are more commonly described among immuno-compromised patients. Furthermore, verrucous lesions may be attributed to acyclovir resistant strains of herpes simplex virus as well as co-infection with fungi and other viruses in this patient population. We describe the first case of verrucous genital herpes infection in an immuno-competent patient.

Background: The natural history of HIV-associated body habitus changes is unclear. In this report, we describe a novel manifestation of HIV-associated lipoaccumulation., Methods: We noted the presence of suprapubic fat pads (pubic lipomas [PLs]) in several patients with preexisting HIV-associated body habitus abnormalities. Subsequently, we evaluated the prevalence of and associated risk factors for development of PLs by undertaking an observational cross-sectional study among patients with known lipodystrophy who attended a metabolic clinic in northern Italy. Inclusion criteria were a physician-confirmed diagnosis of lipodystrophy according to the Multicenter AIDS Cohort Study definition and, for those affected with PL, a readily noticeable PL on physical examination., Results: We evaluated 582 patients with lipodystrophy: 214 female (36.7%) and 368 male (63.3%). The overall PL prevalence was 9.4% (95% confidence interval [CI]: 7.2% to 12.1%; P < 0.0001). PLs were more common among obese than nonobese individuals (34.5%, 95% CI: 17.9% to 5l.3% vs. 8%, 95% CI: 5.9% to 10.6%, respectively; P < 0.0001) and those with preexisting dorsocervical fat pads, commonly called "buffalo humps" (BHs) (18.5%, 95% CI: 12.7% to 25.4% vs. 6.1%, 95% CI: 4.03% to 8.83%, respectively, P < 0.0001; relative risk = 3.02, 95% CI: 1.84% to 4.96%, P < 0.0001). The PL prevalence in the nonobese HIV-infected population (body mass index [BMI] <30, n = 550) was 8.0% (95% CI: 5.9% to 10.6%; P < 0.0001). Logistic regression analyses identified the following factors as associated with a greater likelihood for PL: BMI >30 (beta = 0.18, SE = 0.04; P < 0.001), female gender (beta = 1.06, SE = 0.31; P < 0.001), and shorter duration of HIV infection (beta = -0.005, SE = 0.003; P = 0.04). We used a chain graph model to evaluate risk factors for BH and PL simultaneously. A nonnull interaction between these entities was evident, and this association seemed to be independent of factors positively associated with both (BMI and gender)., Conclusions: PL is a newly recognized manifestation of HIV-associated lipoaccumulation that is more likely to occur among those with coexisting dorsocervical fat pads, suggesting the possibility of a common pathogenesis between the 2 entities. Likewise, PLs are more common among women, obese individuals, and those with a shorter duration of HIV infection. We suggest that PL should be considered part of the HIV-associated lipodystrophy syndrome.

We report on a patient who presented with an unusual manifestation of primary herpes simplex virus (HSV) infection. Furthermore, this case again shows that even the correct use of a condom has limited protecting value. We emphasize the usefulness of informing patients carefully about transmission risks of HSV.
