RESUMO

Muscular hernias are an uncommon condition that typically present as subcutaneous nodules on the legs that appear or enlarge while standing or exercising. They are usually asymptomatic, although they may sometimes be tender or painful and may cause cramps, especially in athletes. Physical examination and ultrasound imaging are the key for determining the diagnosis. We present a 67-year-old woman with tender subcutaneous nodules on both lower legs in which dynamic ultrasound examination confirmed the diagnosis of muscular hernias.

RESUMO

BACKGROUND: Vismodegib is approved for advanced cases of basal cell carcinomas not amenable to surgery or radiotherapy. Large studies on the use of vismodegib in clinical practice are scarce. OBJECTIVES: The main objective of the study was to analyse the evolution and therapeutic management of relapses and lack of response in patients who had received vismodegib for locally advanced and/or multiple basal cell carcinomas in a real-life multicentre setting. METHODS: This nationwide retrospective study collected data on patients treated with vismodegib in 15 specialized centres. We included patients who first received vismodegib until intolerable toxicity, maximum response, or progressive disease. Exploratory research variables referred to patient and tumour characteristics, vismodegib effectiveness and safety, relapse rate and management, and mortality. A multivariable logistic regression model was used to identify predictors of complete clinical response. RESULTS: 133 patients with advanced BCC were included in the registry. The objective response rate (ORR) was 77.5% and nearly half of the patients (45.9%) achieved complete remission. Long-term information and detailed information of subsequent treatments after a regime of vismodegib was available for 115 patients. Only 34% of the patients in this group were subsequently treated with other therapies or vismodegib rechallenge. Sixty-nine percent of the patients who had shown a complete remission with vismodegib remained free of recurrence while 30.7% relapsed. Almost half of the patients who received additional therapies after the first course of vismodegib achieved complete tumour remission. Three and 2 out of 9 patients who were rechallenged with vismodegib achieved complete and partial responses, respectively, with an ORR of 55.5%. CONCLUSION: Our study confirms efficacy of vismodegib in routine clinical practice. The risk of recurrence after achieving complete response with vismodegib was lower than previous reports. Rechallenge with vismodegib is feasible and most patients responded to re-treatment.

RESUMO

OBJECTIVES: Calcium depositions are frequent in multiple inflammatory dermatosis, they can be explored by ultrasound (US) but the patterns of these depositions have not yet been described. The aim of this study is to describe different patterns of calcium deposition in inflammatory dermatoses. METHODS: The clinical and US data of 58 patients from 7 different centers with inflammatory dermatosis showing ultrasonography-detected calcium depositions was retrospectively reviewed. RESULTS: Dystrophic calcinosis represented 86.2%, calciphylaxis 8.6%, and metastatic calcinosis 5.2%. Three different sonographic patterns of calcium deposition were found: 1) thin hyperechoic bands, parallel to the surface of the epidermis, generating a strong and wide posterior acoustic shadow; 2) hyperechoic spots or lumps with a narrow acoustic shadow; and 3) a linear hyperechoic band parallel to the walls of a blood vessel with also a narrow acoustic shadow. The predominant pattern in metastatic calcifications was type 1, in dystrophic calcifications type 2, and in calciphylaxis type 3. In dystrophic calcinosis, cutis deposits were longer and wider than in calciphylaxis (P < .05). CONCLUSION: New data on inflammatory dermatoses with calcium deposition may be useful for the diagnosis and monitoring of calcium deposits and could avoid the performance of more invasive tests, such as a skin biopsy.

RESUMO

Abstract Carney complex is a rare genodermatosis characterized by cardiac and cutaneous myxomas, among other tumors. In the majority of cases, cutaneous myxomas precede the diagnosis of cardiac myxomas, which are the main cause of death in these patients. Despite the fact that the diagnosis of cutaneous myxomas is histopathological, high-frequency ultrasonography plays an essential role in the differential diagnosis with other cutaneous and subcutaneous tumors. The authors of the present study describe, for the first time in the literature, the ultrasonographic features of both variants of cutaneous myxomas, superficial and subcutaneous, in a patient with a Carney complex.

RESUMO

Adenoma of the nipple is a very uncommon benign neoplasm of lactiferous ducts. Its clinical presentation is variable and it can be easily misdiagnosed as a malignancy such as mammary Paget disease or breast intraductal carcinoma. Although dermoscopy and imaging tests such as ultrasonography or mammography can be of help, histological examination is mandatory to confirm the diagnosis. We describe the clinical, dermoscopic, and histopathological findings in a patient with nipple adenoma and discuss the clinical and histological differential diagnosis as well as the different treatment options.

RESUMO

Lipomatous metaplasia of the upper dermis is a rare phenomenon scarcely described in the literature which has always been identified in the context of inflammatory or neoplastic processes. Microscopically, it should be distinguished from pseudolipomatosis cutis, dermal lipoma, nevus lipomatosus, and focal dermal hypoplasia (Goltz syndrome). This is the first report of the histologic and ultrasound evaluation of a patient with extensive involvement and the description of the coincidental finding of an anomalous nonseptate subcutaneous tissue.

RESUMO

Los fármacos inhibidores del factor de necrosis tumoral alfa (anti-TNF alfa) son ampliamente utilizados en diversas especialidades médicas. El principal efecto adverso de estos fármacos es el aumento del riesgo de infecciones. Presentamos el caso de un varón de 30 años con espondilitis anquilosante, en tratamiento desde hacía 2 semanas con golimumab, que consulta por lesiones asalmonadas en tronco, palmas y plantas de 10 días de evolución. Con la sospecha de un secundarismo luético se solicitaron pruebas treponémicas y no treponémicas que confirmaron el diagnóstico. Asimismo se solicitó una punción lumbar, aunque no existía sintomatología neurológica, para descartar neurosífilis. Los casos de sífilis en pacientes en tratamiento con anti-TNF alfa son excepcionales en la literatura y no hay protocolos establecidos que nos guíen sobre cómo actuar ante esta situación


Inhibitors of tumor necrosis factor-alpha (anti-TNF-alpha) are widely used in different medical specialties. The main adverse effect of these agents is the increased risk of infection. We report the case of a 30-year-old man with ankylosing spondylitis who had begun receiving golimumab two weeks earlier. He presented with a 10-day history of salmon-colored lesions on trunk, palms and soles. The clinical suspicion was secondary syphilis. Treponemal and nontreponemal tests confirmed the diagnosis of syphilis. Lumbar puncture was also performed, although there was no neurological involvement, to rule out neurosyphilis. Cases of syphilis in patients in treatment with TNF-alpha inhibitors are uncommon in the literature and there are no established protocols
