ABSTRACT
BACKGROUND: Staging and monitoring of patients with hidradenitis suppurativa (HS) have been traditionally based on clinical findings. However, the physical examination may show important limitations because of its poor sensitivity for differentiating between different lesion subtypes, and its low sensitivity to define the disease's activity. OBJECTIVE: To develop a consensus ultrasound (US) report that could summarize the relevant anatomical characteristics and staging of patients considering the experience of radiologists and dermatologists working on imaging of HS. METHODS: A questionnaire on different aspects related to US examination in HS was performed. A working group, called DERMUS, composed of doctors from 9 countries who have been working in dermatologic US applied in patients with HS on a regular basis were included to evaluate the different items provided. RESULTS: A consensus US report to evaluate HS patients was established. CONCLUSION: The authors present the first attempt to define a HS standardized sonographic report. This model would be the first effort to include this imaging technique as the first elective medical test for staging and monitoring patients, which can support therapeutic decisions by providing earlier, objective, deeper, anatomical, and comparative evaluations in this difficult to treat disease.

We retrospectively collected cases of surgically proven extradigital glomus tumor (EDGT) and reviewed their demographic, clinical, and sonography features. A total of 18 single, subcutaneous EDGTs were gathered. All but one were located in the extremities. EDGTs typically appear as a small, hypoechoic, homogeneous, or slightly inhomogeneous, well-delimited nodule, disposed horizontally and painful under probe pressure. Intranodular vascularization is always present. Feeding artery and efferent vein are typical but inconstant findings.

BACKGROUND: Infantile hemangiomas (IHs) are the most common benign vascular tumors of childhood. Propranolol is an effective drug in treating IH. A reliable and complementary instrument is necessary to evaluate IH response to propranolol in addition to clinical and photographic assessments. Ultrasonography is a simple and non-invasive technique that enables precise measurements of tumor size and contributes to objective follow-up. OBJECTIVE: To demonstrate the use of serial ultrasonography as an adjunctive tool for assessment of IH treatment with propranolol. PATIENTS AND METHODS: A retrospective study of 19 patients with IH treated with propranolol was conducted from January 2009 to March 2014. Data of individual IH volume at the beginning and at least 6 months after the onset of treatment and overall volume reduction by ultrasonographic measurement were obtained. RESULTS: We observed a statistically significant IH volume reduction of approximately 0.51 cm3 . This volume corresponds to an average reduction of 47% in the final volume compared with the initial volume. CONCLUSION: Ultrasonographic measurements contribute to demonstrate tumor regression and IH response to propranolol. Thus, ultrasonography is an important instrument to guide therapeutic strategies.

OBJECTIVES: To support standardization for performing dermatologic ultrasound examinations. METHODS: An international working group, called DERMUS (Dermatologic Ultrasound), was formed, composed of physicians who have been working on a regular basis and publishing in peer-reviewed articles on dermatologic ultrasound. A questionnaire on 5 critical issues about performance of the examinations was prepared and distributed by e-mail. The areas of discussion included technical aspects, main areas of application, minimum number of examinations per year required for assessing competence, qualifications of the personnel in charge of the examination, and organization of courses. Final recommendations were approved on the basis of the agreement of more than 50% of the members. RESULTS: The minimum frequency recommended for performing dermatologic examinations was 15 MHz. Routine use of color Doppler ultrasound and the performance of spectral curve analysis for assessing the main vascularity of lesions were suggested. Three-dimensional reconstructions were considered optional. The main dermatologic applications were benign tumors, skin cancer, vascular anomalies, cosmetic field, nail disorders, and inflammatory diseases. The minimum number of examinations per year suggested by the group for assessing competence was 300. A physician and not a sonographer was recommended to be the person in charge of performing the examination. On course organization, a minimum of 2 levels of complexity (basic and advanced) was suggested. CONCLUSIONS: There is a need to standardize the performance and quality of dermatologic ultrasound examinations. The present guidelines written by an international group of specialists in the field may support this objective.

BACKGROUND: Scleroderma is a chronic autoimmune disease characterized by progressive connective tissue sclerosis and microcirculatory changes. Localized scleroderma is considered a limited disease. However, in some cases atrophic and deforming lesions may be observed that hinder the normal development. Literature reports indicate phototherapy as a therapeutic modality with favorable response in cutaneous forms of scleroderma. OBJECTIVES: This study had the purpose of assessing the phototherapy treatment for localized scleroderma. METHODS: Patients with localized scleroderma were selected for phototherapy treatment. They were classified according to the type of localized scleroderma and evolutive stage of the lesions. Clinical examination and skin ultrasound were used to demonstrate the results thus obtained. RESULTS: Some clinical improvement was observed after an average of 10 phototherapeutic sessions. All skin lesions were softer at clinical palpation with scores reduction upon pre and post treatment comparison. The ultrasound showed that most of the assessed lesions presented a decrease in dermal thickness, and only five maintained their previous measure. Treatment response was similar regardless of the type of phototherapeutic treatment employed. CONCLUSIONS: The proposed treatment was effective for all lesions, regardless of the phototherapeutic modality employed. The improvement was observed in all treated skin lesions and confirmed by clinical evaluation and skin ultrasound.

FUNDAMENTOS: A esclerodermia é uma doença autoimune caracterizada pela esclerose progressiva do tecido conjuntivo e alterações da microcirculação. A forma cutânea é considerada uma doença autolimitada. No entanto, em alguns casos, ocorrem lesões atróficas, deformantes, que dificultam o desenvolvimento normal. Relatos da literatura apontam a fototerapia como uma modalidade terapêutica com resposta favorável nas formas cutâneas da esclerodermia. OBJETIVOS: Este trabalho teve como objetivo avaliar o tratamento da esclerodermia cutânea com fototerapia. MÉTODOS: Foram selecionados pacientes com diagnóstico de esclerodermia cutânea para o tratamento com fototerapia, os quais foram classificados de acordo com o tipo clínico e o estágio evolutivo das lesões. Utilizou-se o exame clínico e a ultrassonografia da pele como metodologia para demonstrar os resultados obtidos com o tratamento proposto. RESULTADOS: Foi observado o início da melhora clínica das lesões com média de 10 sessões de fototerapia. A palpação clínica mostrou amolecimento em todas as lesões estudadas, com redução nos escores de avaliação estabelecidos. No exame de ultrassom, a maioria das lesões avaliadas mostrou diminuição da espessura da derme, e apenas cinco mantiveram sua medida. Não se observou diferença na resposta ao tratamento de acordo com o tipo de fototerapia instituída. CONCLUSÕES: O tratamento proposto foi efetivo em todas as lesões, independentemente do tipo de fototerapia realizada. A melhora foi observada em todas as lesões tratadas e comprovada pela avaliação clínica e pelo exame de ultrassom da pele.

OBJETIVO: Apresentar os aspectos ultra-sonográficos da esclerodermia localizada e relacioná-los com os aspectos clínicos. MATERIAIS E MÉTODOS: Foram analisadas 23 lesões de esclerodermia localizada em 21 pacientes. Foi utilizado equipamento Logiq 700 com transdutor linear de 6-14 MHz. Foram avaliados, pelo dermatologista, o estágio da doença (inflamatório ou atrófico), e pelo radiologista, a espessura e a ecogenicidade da derme nas regiões afetadas e sãs adjacentes. Foi feito acompanhamento de sete casos após tratamento. RESULTADOS: Todas as lesões apresentaram perda do padrão ultra-sonográfico normal da derme. Os casos de lesão clinicamente atrófica (52,2 por cento; 12/23) corresponderam a redução da espessura e aumento da ecogenicidade da derme e os casos de lesão clinicamente inflamatória (47,8 por cento; 11/23) corresponderam a aumento da espessura e redução da ecogenicidade da derme. Controles pós-tratamento mostraram alterações na espessura da derme. CONCLUSÃO: Os achados ultra-sonográficos nos permitem associar o aumento da espessura e a redução da ecogenicidade da derme com a fase inflamatória da doença, e a redução da espessura e o aumento da ecogenicidade da derme com a fase atrófica da doença. Notamos também que é possível quantificar a espessura da derme e usar essa informação no controle pós-tratamento associada à avaliação clínica.
OBJECTIVE: To describe ultrasonographic findings of localized cutaneous scleroderma and correlating them with clinical findings. MATERIALS AND METHODS: Twenty-three lesions of localized cutaneous scleroderma in 21 patients were evaluated with a Logiq 700 equipment coupled with a 6-14 MHz linear transducer. The disease stage (athrophic or inflammatory) was evaluated by a dermatologist, and the ultrasonographic findings (skin thickness and echogenicity) for both the affected and adjacent healthy regions were evaluated by a radiologist. Seven of the cases underwent post-treatment follow-up. RESULTS: All the affected regions presented loss of the normal ultrasonographic pattern of the dermis. Cases with clinically atrophic lesions (52.2 percent; 12/23) corresponded to reduction in the thickness and increase in the echogenicity of the dermis, and clinically inflammatory lesions (47.8 percent; 11/23) corresponded to decrease in echogenicity and increase in the thickness of the dermis. Post-treatment follow-up demonstrated alterations in the dermis thickness. CONCLUSION: The ultrasonographic findings allow the correlation between increase in the thickness/decrease in echogenicity of the dermis with the inflammatory phase of the disease, and decrease of the thickness/increase in echogenicity of the dermis with the atrophic phase. Also, it could be observed that it is possible to quantify the thickness of the dermis, utilizing this information associated with the clinical evaluation in the post-treatment follow-up.
