ABSTRACT
Primary low-grade lymphoma of the mucosa-associated lymphoid tissue (MALT) type lymphoma of the bladder is rare. A relationship between MALT lymphoma of the urinary bladder and chronic cystitis has been proposed by some reports. Additionally a relationship between MALT lymphoma of the urinary bladder and Helicobacter pylori has been reported. Here we present a case of regression of urinary bladder MALT lymphoma after antibiotic therapy, using H. pylori eradication protocol in an elderly patient, who had a high risk of treatment related mortality in curative systemic chemotherapy. The patient is a 74-year-old woman who had a history of chronic cystitis. She was diagnosed with stage IIA primary MALT lymphoma of the urinary bladder and was treated with H. pylori eradication triple therapy for 2 weeks. After 2 months, there was a marked regression of the bladder MALT lymphoma lesion in a computed tomography scan of the abdomen.

La cistitis intersticial se define como un síndrome clínico caracterizado por un incremento de la frecuencia urinaria, urgencia miccional y/o dolor abdominal o perineal en ausencia de infección urinaria o enfermedad conocida del aparato urinario. Se divide de acuerdo a los hallazgos citoscópicos en ulcerativa o no. La base del diagnóstico es clínica apoyada en scores de probabilidad y pruebas invasivas. Con la comprensión de la fisiopatología se ha desarrollado un abanico de posibilidades terapéuticas. Comunicamos el caso de una paciente sintomática por cuatro años con diagnóstico de cistitis intersticial con úlcera de Hunner por cistoscopia y excelente respuesta a la amitriptilina. Es una enfermedad que produce considerable alteración de la calidad de vida, por lo que es importante que los médicos estén familiarizados con este cuadro.
Interstitial cystitis is characterized by over 6 months of chronic pain, pressure and discomfort felt in the lower pelvis or bladder. It is often relieved with voiding, along with daytime frequency and nocturia in the absence of an urinary tract infection. The disorder can be divided clinically into two groups -ulcerative and non-ulcerative- based on cystoscopic findings and response to treatment. Management follows an approach of applying the least invasive therapy that affords sufficient relief of symptoms. We report a case of a patient with interstitial cystitis. The diagnosis was performed by symptoms and lesion in the cystoscopy and excellent response to amitriptyline.
