Resumen
La gastritis colágena, una afección rara, implica el engrosamiento subepitelial del colágeno. Este informe de caso detalla su diagnóstico en una mujer joven adulta que presenta síntomas gastrointestinales.
Área de la Ciencia:
- Gastroenterología
- Patología
Sus antecedentes:
- La gastritis colágena (GC) es un trastorno gastrointestinal raro.
- Se define por la deposición excesiva de colágeno subepitelial (>10 μm) en el estómago.
- La GC puede presentarse con síntomas gastrointestinales superiores inespecíficos.
Objetivo del estudio:
- Informar un caso de gastritis colágena en una mujer joven adulta.
- Destacar las características diagnósticas de la GC en la endoscopia y la histología.
Principales métodos:
- Una mujer joven adulta se presentó con síntomas gastrointestinales superiores.
- Se realizó una endoscopia gastrointestinal superior, que reveló mucosa gástrica atrófica.
- Se obtuvo una biopsia para examen histopatológico.
Principales resultados:
- La histopatología confirmó un aumento de la deposición de colágeno exclusivamente en la capa subepitelial.
- La tinción de tricrómico de Masson resaltó eficazmente el engrosamiento colágeno.
- Los hallazgos fueron consistentes con los criterios diagnósticos de gastritis colágena.
Conclusiones:
- La gastritis colágena es una afección rara que puede afectar a adultos jóvenes.
- Los hallazgos endoscópicos de mucosa atrófica pueden justificar una mayor investigación.
- El examen histopatológico con tinciones específicas es crucial para diagnosticar la gastritis colágena.
