RESUMO

Pilomatrixoma or pilomatricoma is a benign adnexal neoplasm originating from the hair matrix, the inner sheath of the hair follicle, and the hair cortex. Although it is considered rare in adults, numerous cases have been documented in the literature. We present a case of an elderly male who sought consultation due to a newly appearing nodular lesion on his left forearm. Several benign and malignant entities were included in the original differential diagnosis. High-frequency ultrasonographic features suggested a cystic neoplasm with calcification and mild intralesional vascularity. Ultimately, histopathological examination confirmed the diagnosis of pilomatricoma. In this study, our aim is to review the importance of the available diagnostic tools, such as dermoscopy, and the emerging utility of cutaneous high-frequency ultrasonography. Some rarer pathological variants are also discussed, including perforating, anetodermic, bullous and pigmented pilomatricoma. We hope that exposure to these clinical, dermoscopic, ultrasonographic, and histopathological images will encourage clinicians to consider pilomatricoma in their differential diagnosis when approaching nodular lesions, regardless of location and patient's age.

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

Alkaptonuria is a rare autosomal recessive metabolic disorder with wide systemic involvement including pigment deposition. We present an unusual case diagnosed by an image obtained via telemedicine showing pigment deposition in the earlobe. We highlight how this clue may allow prompt diagnosis of alkaptonuria and prevent disease progression.

RESUMO

Erythromelalgia is an infrequent syndrome with a profound impact on quality of life. Its management is usually challenging and multiple treatments have been reported with variable response rates. To the best of our knowledge, we present the first case of erythromelalgia successfully treated with topical oxymetazoline.

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

Interstitial granulomatous dermatitis (IGD) is a rare dermatosis generally seen in the setting of rheumatic diseases, but also hematological disorders, internal malignances, infections, or drug induced. Herein, we report an exceptional case of an IGD with a clear chronological association with tocilizumab onset and cessation in a patient with adult-onset Still's disease. We review the granulomatous cutaneous reactions so far reported with this novel therapy: sarcoidosis, granuloma annulare, and IGD. Tocilizumab is a humanized anti-interleukin 6 receptor monoclonal antibody useful for the treatment of various systemic inflammatory disorders. Lately, it has found useful also for granulomatous diseases such as giant cell arteritis and even a promising response in IGD. Therefore, we believe our case adds the possibility of an IGD presenting as a paradoxical reaction.

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

RESUMO

Palmoplantar epidermoid cysts can range in clinical presentation from an asymptomatic slowly enlarging mass to a painful nodule. We report two cases: an epidermoid cyst on the sole and another on the palm. This article reviews the possible etiology, diagnosis, and prognosis of palmoplantar epidermoid cysts.
