RESUMEN
A síndrome de arlequim é uma rara desordem autonômica que se caracteriza por anidrose e falta de rubor unilateral da face, podendo acometer as regiões cervical e torácica. De forma paradoxal, há rubor e sudorese compensatórios no lado contralateral à alteração. É idiopática na maioria dos casos, mas pode ser congênita, secundária a lesões estruturais e à iatrogenia pós-cirúrgica. O tratamento é direcionado ao fator causal. Descreve-se caso de paciente com diagnóstico de síndrome de arlequim idiopática, sendo realizada aplicação de toxina botulínica na hemiface acometida pelos sintomas compensatórios com boa resposta terapêutica
Harlequin syndrome is a rare autonomic disorder characterized by anhidrosis and lack of unilateral flushing of the face, which may affect the cervical and thoracic regions. Paradoxically, there is compensatory flushing and sweating on the contralateral side to the alteration. It is idiopathic in most cases, but it can be congenital or secondary to structural or post-surgical iatrogenic lesions. Treatment is directed at the causative factor. We describe the case of a patient with a diagnosis of idiopathic Harlequin Syndrome with botulinum toxin application in the hemiface affected by compensatory symptoms with good therapeutic response.
RESUMEN
Subungual basal cell carcinoma (BCC) is a rare disorder associated with many factors, including contact with some topical and oral substances. A differential diagnosis and an early approach are important to minimize the functional damage of the limbs affected by this type of tumor. We report a case of subungual BCC in a 70-year-old woman that was managed by surgical excision. The patient's medical history included the previous use of arsenic. We emphasize the contribution of an early diagnosis to achieve better treatment results in this instance.
RESUMEN
Descrito por Jadassohn e também conhecido como nevo organoide, o nevo sebáceo é considerado hamartoma que exibe má-formação folicular, sebácea, écrina e apócrina de graus variados. Durante a idade adulta, de dez a 30% dos pacientes com nevo sebáceo de Jadassohn têm risco de desenvolver neoplasia cutânea ou anexial. Relatamos caso de paciente com nevo sebáceo de Jadassohn associado a múltiplas neoplasias (benignas e malignas) de diferentes linhagens e ressaltamos a importância do conhecimento dessa entidade e do exame do couro cabeludo por parte do dermatologista.
Described by Jadassohn and also known as organoid nevus, nevus sebaceous is considered a hamartoma that exhibits follicular, sebaceous, eccrine and apocrine malformations of varying degrees. Between 10% and 30% of patients with sebaceous nevi of Jadassohn are at risk of developing cutaneous or adnexal neoplasia during adulthood. The authors describe the case of a patient with nevus sebaceous of Jadassohn associated with multiple tumors (benign and malignant) of different strains, highlighting the importance of the dermatologist physician's knowing this entity and how to perform an examination of the scalp.
