Usefulness of polymerase chain reaction analysis in a case of clinically and histologically atypical nodular granulomatous secondary syphilis.

We report a case of a nodular granulomatous secondary syphilis histologically resembling tuberculids in a patient with positive quantiferon test and serology for syphilis. Polymerase chain reaction (PCR) analysis led to the diagnosis. We underline the usefulness of PCR in clinically and histologically doubtful cases in order to avoid misdiagnosis and delay treatment.

Exploring the Relationship Between Dermatology Life Quality Index, Eczema Area and Severity Index, and Sleep Numerical Rating Scale and Pruritus Numerical Rating Scale in Patients with Atopic Dermatitis Treated with Dupilumab.

Objective: Patients with atopic dermatitis (AD) experience decreased quality of life (QoL). Here we describe the relationship between severity and QoL-related scores in patients with moderate-to-severe AD treated with dupilumab. Patients and Methods: This was a real-life, retrospective, and observational study involving patients with AD treated with dupilumab. Treatment effectiveness was evaluated based on the changes in the eczema area and severity index (EASI), sleep quality numerical rating scale ,and pruritus numerical rating scale (PNRS), as well as the dermatology life quality index (DLQI). The relationship between each of them was analyzed. After the first data collection at baseline, patients were re-evaluated at 3 subsequent follow-ups (4, 8, and 12 months). Results: A total of 52 patients were enrolled in the study. At 4 months, the change in DLQI is more correlated with PNRSs (r = 0.643, P < 0.001) than the other scores considered. At 8 months, however, the change in DLQIs correlates similarly both with PNRSs (r = 0.644, P < 0.001) and with the change in EASIs (r = 0.633, P < 0.001). At 12 months of treatments, however, the trend reverses and the correlation with EASIs becomes higher (r = 0.735, P < 0.001) than PNRSs (r = 0.0.659, P < 0.001). Conclusions: The results of our study show that the reduction in the impact on QoL for AD patients in the first months of therapy with dupilumab correlates more with the control of pruritus than with the disappearance of skin lesions.

Not only monkeypox infection: Keratoderma blenorrhagicum.

We report the case of a 18-year-old boy affected by keratoderma blenorrhagicum mimicking monkeypox infection. PCR test in urine and urethral swab positive for chlamydia trachomatis and a biopsy performed on a lesion of the palm of the hand led to the correct diagnosis. The current monkeypox outbreak is an evolving situation, thus a better understanding of morphological, clinical and temporal features could help in prompt diagnosis of this infection.

Folliculosebaceous units are a frequent finding in early lichen sclerosus of the foreskin.

BACKGROUND: Folliculosebaceous units (FSU) has been considered an early target of inflammation in vulvar lichen sclerosus (VLS). This diagnostic clue is not reported in lichen sclerosus (LS) of the foreskin (FLS) that is normally hairless. We evaluated the presence and inflammation of FSU and sebaceous glands (SG) in LS of the foreskin. METHODS: Histological specimens from therapeutic circumcision were assessed in order to evaluate the frequency and inflammation of FSU and SG in LS. RESULTS: Ninety-eight cases, grouped into 46 early (group 1) and 52 overt (group 2) FLS were included in the study. SG-FSU were found in 95.7% of group 1, and 65.4% of group 2 cases. Their density was inversely correlated with patient age (P=0.0014). We observed perifollicular inflammation in all cases with visible SG-FSU and frequent FSU abnormalities. CONCLUSIONS: SG and FSU were frequent in early FLS and decreased in advanced disease and adults. We hypothesize that SG and FSU are involved in the inflammatory process leading to FLS. These data, which need further investigation, could help to better understand the pathogenesis of FLS.
