    Background: Pain is not a trivial issue for hidradenitis suppurativa (HS) patients and has been considered a domain in the Core Outcome Set. To date, there is no evidence about pain caused by the ultrasound examinations. Objective: The aim of the study was to assess the presence of pain generated by the ultrasound examinations of HS patients. Methods: A multicentric cross-sectional study for detecting pain during the ultrasound examinations of HS patients using a validated verbal questionnaire immediately after the imaging studies. Statistical analysis included demographic data and possible associations with sex, age, location, clinical (Hurley), and ultrasonographic scoring (SOS-HS). The statistical tests were two proportions Z test, chi(2) test, Student's t test, and ANOVA. A p < 0.05 was considered significant. Results: 317 patients met the criteria. 77.3% of them did not present pain. Of cases with pain, 59.8% were mild, 16.7% moderate, and 23.6% severe. No significant association was found with sex, age, staging, location, or the number of affected regions. Although nonsignificant, severe pain cases were more frequent in the clinical Hurley III and ultrasonographic SOS-HS III stages. Conclusion: Pain generated by the ultrasound examination of HS patients is infrequent.

    Ultrasonography of Facial and Submandibular Hidradenitis Suppurativa and Concomitance with Acne Vulgaris
    (2024) Wortsman, Ximena; Ortiz-Orellana, Gabriela; Valderrama, Yessenia; Ferreira-Wortsman, Camila; Reyes, Francisco; Herane, Maria Isabel
    ObjectivesTo describe the ultrasound characteristics of facial and submandibular hidradenitis suppurativa (HS) and detect acne vulgaris (AV) concomitance in these cases.MethodsWe performed a retrospective study of the ultrasound images of patients with facial HS who had been clinically evaluated by dermatologists. The reported ultrasound diagnostic criteria, severity (mSOS-HS), and activity (US-HAS) staging of HS were used to categorize the patients. The finding of fragments of hair tracts within the key lesions (dilated hair follicles, pseudocysts, fluid collections, and tunnels) was considered a pivotal sign to discriminate HS from AV. Demographic and morphological analysis of the images were considered.ResultsThirty-three patients met the criteria (78.8% male/21.2% female). Of these, the mSOS- HS scoring was stage I in 51.5%, stage II in 27.3%, and stage III in 21.2%. Dilation of the hair follicles and the presence of pseudocysts, fluid collections, and tunnels were detected in the HS cases; 63.1% of pseudocysts, 62.4% of tunnels, and 46.2% of fluid collections contained fragments of hair tracts. In all HS cases, there was a key lesion(s) with fragments of hair tracts. Four (12.1%) patients showed concomitant facial HS and acne ultrasound lesions. The acne lesions were pseudocysts without inner hair tract fragments in all cases, and the SOS-Acne scoring was stage II for all of them.ConclusionFacial HS can be detected on ultrasound and shows a morphology similar to that of HS in other corporal regions. In some cases, facial HS could be concomitant with AV. The subclinical ultrasonographic information can support a better management of these cases.

    Ultrasound in Sports and Occupational Dermatology
    (2021) Wortsman, Ximena; Ferreira-Wortsman, Camila
    Chronic exposure to trauma, friction, or extreme conditions can generate cutaneous or ungual lesions in sports and certain occupations. Although some of these dermatologic conditions are diagnosed with a naked-eye examination, there are cases in which the provision of the underlying anatomic alterations can be helpful for the diagnosis and management. In comparison with computed tomography or magnetic resonance imaging, ultrasound has the highest axial resolution, which is critical for the observation of anatomic changes in the skin and nail. We review the ultrasound characteristics of frequent cutaneous and ungual lesions related to sports and occupations with a clinical correlation. The ultrasound features in some particular conditions such as "biker's and surfer's panniculitis," "fiddler's neck," piezogenic papules, and lipoatrophy semicircularis, among others, are discussed.
