Resumen
Una rara úlcera sacra de Marjolin, un tipo de cáncer de piel, se desarrolló a partir de un absceso de la espalda baja. Este caso pone de relieve la necesidad de un diagnóstico temprano de las úlceras de Marjolin, incluso con presentaciones atípicas, para mejorar los resultados de los pacientes.
Área de la Ciencia:
- Dermatología Dermatología dermatología.
- Oncología Oncología.
- Patología Patología Patología.
Sus antecedentes:
- Las úlceras de Marjolin son crecimientos malignos de la piel a menudo relacionados con heridas crónicas, particularmente cicatrices de quemaduras.
- Aunque por lo general surgen a lo largo de muchos años, las presentaciones subagudas son menos comunes.
- Este caso involucra una úlcera sacra de Marjolin que se desarrolla después de abscesos de la espalda baja.
Objetivo del estudio:
- Para reportar un raro caso de una úlcera sacra de Marjolin.
- Para enfatizar la importancia de considerar las úlceras de Marjolin en presentaciones de heridas no clásicas.
- Para resaltar la necesidad de sospechas y diagnósticos tempranos.
Principales métodos:
- Presentación del informe de caso.
- Revisión de la historia clínica del paciente centrándose en las heridas crónicas y los abscesos.
- Examen clínico y patológico de la malignidad cutánea.
Principales resultados:
- Se identificó una úlcera sacra de Marjolin en un paciente con antecedentes de abscesos de espalda baja.
- La presentación fue subaguda, diferente del desarrollo típico de la herida crónica.
- El diagnóstico fue confirmado a través de la evaluación clínica y patológica.
Conclusiones:
- Las úlceras sacrales de Marjolin pueden surgir de afecciones subagudas como abscesos, no solo de heridas crónicas.
- La sospecha y el diagnóstico tempranos son cruciales, especialmente en pacientes que carecen de los factores de riesgo clásicos de úlcera de Marjolin.
- Este caso amplía la comprensión de la etiología y la presentación de la úlcera de Marjolin.

01:28Peptic Ulcer Disease II: Pathophysiology
2.2K
Peptic Ulcer Disease (PUD) is characterized by the development of ulcers in the stomach or duodenal mucosa. Its pathophysiology is complex, involving a balance between damaging and protective elements.
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.

01:30Peptic Ulcer Disease I: Introduction
891
Peptic Ulcer Disease (PUD) is characterized by mucosal excavation in the esophagus, stomach, pylorus, or duodenum. It can manifest as acute or chronic based on the extent and duration of mucosal involvement.
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...

Medical treatment strategies for peptic ulcers encompass various methods. The primary goal of treatment is to diminish gastric acidity and strengthen mucosal defense mechanisms.
The therapeutic approach involves ensuring adequate rest, implementing drug therapy, promoting smoking cessation, making dietary modifications, and emphasizing long-term follow-up care.

01:29Drugs for Treatment of Ulcerative Colitis in IBD
535
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

01:22Pathophysiology of Peptic Ulcer Disease: Injurious Factors
1.3K
Peptic ulcers are sores on the stomach's inner lining and the upper small intestine, which are the result of disruptions in the mucosal layer that houses parietal cells which produce gastric acid, and chief cells which secrete pepsinogen.
In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds...
