ABSTRACT
RESUMEN Introducción: el Síndrome de Sjögren es una exocrinopatía autoinmune caracterizada por un infiltrado inflamatorio, con predominio de linfocitos en glándulas exocrinas y tejidos extraglandulares. La lesión glandular se caracteriza por la hiposecreción en mucosa oral y ocular. Caso Clínico: paciente femenina de 13 años de edad, procedente del municipio de Consolación del Sur, en la provincia de Pinar del Río, con Síndrome de Sjögren, cuya manifestación clínica inicial fue extraglandular, con el riñón como principal órgano afectado bajo la forma de acidosis tubular renal distal tipo I. Conclusiones: se demuestra que la realización de una minuciosa anamnesis, exploración clínica y la utilización de distintas herramientas diagnósticas, hacen posible un diagnóstico precoz de la enfermedad y de sus manifestaciones extraglandulares.
ABSTRACT Introduction: the Syndrome of Sjögren is an exocrinopatía autoinmune characterized by an infiltrated inflammatory, with linfocitos prevalence in glands exocrinas and knitted extraglandulares. The glandular lesion is characterized by the hiposecreción in mucous oral and ocular. Clinical case: a 13-year-old female adolescent with Sjögren's Syndrome is presented, whose initial clinical manifestation was extra-glandular, with the kidney as the main affected organ in type-I distal renal tubular acidosis. Conclusions: it is demonstrated that the realization of a meticulous anamnesis, clinical exploration and the use of different diagnostic tools, they make possible a precocious diagnosis of the illness and of their manifestations extraglandulares.
ABSTRACT
INTRODUCTION: Cystadenoma is an uncommon epithelial neoplasia that arises from the salivary glands. The malignancy can affect structures such as the larynx, nasopharynx, buccal mucosa, and palate. OBJECTIVE: To describe a case of a giant cystadenoma of the floor of the mouth treated at a public hospital in midwestern Brazil. CASE REPORT: The patient was a 46-year-old woman with complaints of difficulties in articulating words and swallowing solid food and vocal fatigue. The progression of the disease since the initial consultation, the results of clinical examinations, and the outcome of surgery are described. FINALS COMMENTS: Cystadenoma must be considered in the differential diagnosis of cystic injuries in the floor of the mouth if the patient's symptoms are suggestive of this malignancy.
ABSTRACT
This article describes the location, anatomy, histology and ontogeny of adult Schwarziana quadripunctata exocrine glands. These glands appear either as individualized organs (salivary gland system and Dufour gland) or as epidermis differentiation (tegumentary glands). Variations in the occurrence and degree of development among colony components with regard to their degree of maturity are also described.
O presente artigo descreve a localização, a anatomia, a histologia e o desenvolvimento das glândulas exócrinas presentes em operárias, rainhas e machos de Schwarziana quadripunctata. As glândulas apresentam-se como órgãos individualizados (glândulas do sistema salivar e glândula de Dufour) ou como simples diferenciações da epiderme (glândulas tegumentares). As variações na ocorrência e no grau de desenvolvimento dos componentes da colônia, ou de seu grau de amadurecimento, também são apresentadas.
