Uncommon Presentation of a Giant Cell Tumor of the Tendon Sheath of the Hand: A Case Report.

A giant cell tumor of the tendon sheath (GCTTS) presents as a rare neoplasm demanding a heightened index of suspicion for precise diagnostic evaluation, especially when manifesting in the digital phalanges, as it is part of a group of neoplasms known as tenosynovial giant cell tumors (TCGTs). An accurate and timely diagnosis is crucial, as it significantly enhances treatment outcomes for this heterogeneous group of lesions. We describe the case of a male patient who presented with multiple nodules in the fourth finger of his left hand and was ultimately diagnosed with a localized form of a GCTTS, an unusual presentation for localized forms of this entity. Our objective is to outline the diagnostic and therapeutic approach, discussing options for differential diagnosis and treatment modalities. To achieve this, we conducted a literature review and compared our findings and the observed evolution in our patient. Early recognition of hand tumors allows for timely diagnosis, facilitating optimal resections during surgical procedures. This, in turn, reduces morbidity and enhances the functionality of the affected extremity, as detailed in the current case.

Hernia interna por divertículo de Meckel: una causa rara de obstrucción intestinal / Internal Hernia due to Meckel's Diverticulum: A Rare Cause of Intestinal Obstruction

Resumen El divertículo de Meckel (DM) es el remanente del conducto onfalomesentérico y se considera la malformación congénita más común del tracto gastrointestinal. La mayoría de los pacientes son asintomáticos; sin embargo, aquellos en los que se desarrollan síntomas, estos pueden manifestarse como: dolor abdominal, hemorragia de tracto gastrointestinal, perforación u obstrucción intestinal. El objetivo de este reporte es presentar un caso de hernia interna secundaria a un divertículo de Meckel, siendo esta una causa poco frecuente de obstrucción intestinal.

Abstract Meckel's diverticulum is the remnant of the omphalomesenteric duct and is considered the most common congenital malformation of the gastrointestinal tract. Most patients are asymptomatic, however patients who develop symptoms can manifest: abdominal pain, gastrointestinal tract bleeding, intestinal perforation or obstruction. The objective of this report is to present a case of internal hernia secondary to a Meckel's diverticulum, a rare cause of bowel obstruction.

"Sigma Volvere" acerca del vólvulo de sigmoides, diagnóstico y manejo quirúrgico, reporte de serie de casos / "Sigma Volvere" About Sigmoid Volvulus, Diagnosis and Surgical Management. Case Series Report

Resumen Presentar la experiencia en el diagnóstico clínico-radiológico y tratamiento de vólvulo sigmoideo. Se incluyeron casos con clínica sugestiva de obstrucción intestinal secundaria a vólvulo de sigmoides. Los factores de riesgo fueron: sexo masculino, mayor estancia hospitalaria, edad mayor a 70 años y la tríada clásica. Los estudios de imagen resultaron concluyentes, siendo la radiografía de abdomen y la tomografía simple de abdomen, los de elección para el abordaje diagnóstico. El vólvulo de sigmoides tiene un patrón clínico-radiológico predecible, un examen físico minucioso y estudios de gabinete de primera línea pueden ser concluyentes. La opción terapéutica para estos pacientes fue la cirugía.

Abstract To present the experience in clinical/radiological diagnosis and treatment of sigmoid volvulus. Cases with symptoms suggestive of intestinal obstruction secondary to sigmoid volvulus were included. The risk factors were: male sex, longer hospital stay, age over 70 years and the classic triad. Imaging studies were conclusive, with abdominal radiography and simple abdominal tomography being the tests of choice for the diagnostic approach. Sigmoid volvulus has a predictable clinical-radiological pattern, a thorough physical examination and first-line cabinet studies can be conclusive. The therapeutic option for these patients was surgery.
