Horner syndrome as a manifestation of thyroid carcinoma: a rare association / Síndrome de Horner como manifestação clínica de carcinoma da tireoide: uma associação rara

An 82-year-old patient presented a progressively growing hard thyroid nodule, and left ptosis. Additionally, ophthalmologic evaluation revealed ipsilateral miosis, diagnostic findings of Horner syndrome. Computerized tomography revealed a 7.5-cm thyroid mass infiltrating the main neck vessels. Although clinical and imaging data were suggestive of poorly differentiated thyroid carcinoma, fine-needle aspiration led to the diagnosis of papillary carcinoma. Paliative care was proposed to the patient due to the advanced stage of the neoplasm and to significant comorbidities. Horner syndrome is an infrequent manifestation of thyroid disorders and benign etiologies are more often implied. Malignant thyroid neoplasms represent a rare cause of Horner syndrome. However, an appropriate and prompt diagnosis is paramount for timely treatment of rare thyroid malignancies.

Paciente de 82 anos apresentando-se com nódulo tireoidiano de crescimento progressivo e ptose palpebral esquerda. O exame oftalmológico revelou ainda miose ipsilateral e achados diagnósticos de síndrome de Horner. A tomografia computadorizada mostrou massa tireoidiana de 7,5 cm infiltrando os grandes vasos do pescoço. Apesar dos dados clínicos e imagiológicos sugestivos de um carcinoma pouco diferenciado da tireoide, a citologia aspirativa foi diagnóstica de carcinoma papilar. Em função do estádio avançado da neoplasia e das comorbilidades significativas, foi proposta para terapêutica paliativa. A síndrome de Horner é uma manifestação clínica infrequente em tumores tireoidianos, estando as condições benignas maioritariamente implicadas. As neoplasias malignas da tireoide representam uma causa rara de síndrome de Horner. Contudo, um diagnóstico adequado e expedito é fundamental para o tratamento atempado nos raros casos de malignidade da tireoide.

Síndrome disautonómico de Ross: variaciones de un tema / Disautonomic Ross syndrome: variations about one theme

El síndrome de Ross fue descrito en 1958 como una afección degenerativa del sistema nervioso autónomo definido por la tríada de anhidrosis generalizada, disminución de los reflejos tendinosos y pupila tónica. Desde su descripción inicial se han descrito cerca de cuarenta casos. Comunicamos tres pacientes con variantes de interés que incluyen la presencia de espasmos cíclicos espontáneos del esfínter de iris, el desarrollo conjunto de síndrome de Holmes-Adie en un lado y síndrome Horner posganglionar en el otro, trastornos del desarrollo piloso en el lado de la anhidrosis, alteraciones de la motilidad intestinal, lengua sin papilas gustativas y disfunción sexual.

Ross Syndrome was described in 1958 as a degenerative condition of the autonomic nervous system defined by a triad of generalized anhidrosis, reduction of tendon reflexes and tonic pupil. Since its initial description about 40 cases have been described. We communicate three cases with variants of interest involving the presence of the simultaneous development of syndrome of Holmes-Adie on one side and Horner syndrome in the other, disorders of pilous follicle development on the side of anhidrosis, spontaneous disturbances of intestinal motility, tonque without papillae and sexual dysfunction.

Simple goiter presenting as Horner's Syndrome: a case report

A young female patient presented with goitre and Horner's syndrome. Examination and investigations were suggestive of malignancy of thyroid. However, final histopathological diagnosis turned out to be being goitre. It is unusual and rare for simple goitre to present with Horner's syndrome. The nature of goitre should be confirmed before a definite surgical approah is adapted
