Malakoplakia in a healthy young female patient

Malakoplakia is a rare granulomatous disease that occurs commonly in the urinary tract and secondarily in the gastrointestinal tract. Most reported cases of malakoplakia are associated with immunosuppressive diseases or chronic prolonged illness. Here, we report a rare case of malakoplakia in a young healthy adolescent without any underlying disease. A 19-year-old female was referred to our hospital following the discovery of multiple rectal polyps with sigmoidoscopy. She had no specific past medical history but complained of recurrent abdominal pain and diarrhea for 3 months. A colonoscopy revealed diverse mucosal lesions including plaques, polyps, nodules, and mass-like lesions. Histological examination revealed a sheet of histiocytes with pathognomonic Michaelis-Gutmann bodies. We treated the patient with ciprofloxacin, the cholinergic agonist bethanechol, and a multivitamin for 6 months. A follow-up colonoscopy revealed that her condition was resolved with this course of treatment.

Pulmonary malakoplakia: A report of two cases.

Malakoplakia of lung is an unusual condition that has been reported to occur in association with immunocompromised state, particularly in those with acquired immunodeficiency syndrome. We present two cases of pulmonary malakoplakia in immunocompetent individuals. The diagnosis was made on histopathological examination of surgically resected specimen.

Malacoplaquia renal: relato de caso / Renal malakoplakia: a case report

Relata-se caso clássico de malacoplaquia acometendo rim de paciente de 44 anos. Abordam-se aspectos histopatológicos além da patogenia da lesão.

This is a report of 44 years old patient with renal malakoplakia. We study histopathological aspects and pathogenesis of this lesion.

Malakoplakia of the kidney--a case report.

Malakoplakia is a rare disease expressed as a special type of inflammatory reaction to infection with various bacteria and fungi. We present a case of renal malakoplakia in a 30-year-old female patient. The symptoms were not characteristic enough for making the ture diagnosis preoperatively. A preoperative diagnosis of renal cell carcinoma was made in this case.

Malacoplaquia intestinal / Colonic malakoplakia

Malacoplakia is a chronic granulomatous disease of unknown origin. However immunodeficiency states (immunossuppressive medication, old people, renal transplantation, leukaemia, diabetes mellitus, malnutrition and others) have been associated with patients with malacoplakia. An infectious cause of malakiplakia is suggested by the finding of coliform bacteria in the phagolysosomes of macrophages. The histologic study is characterized by a infiltrate of large macrophages (Hansenmann cells) with pathognomonic inclusions containing siderocalcific structures (Michaelis-Gutmann bodies). Most of the cases reported in literature, involve the genitourinary tract, but other structures can be affected (brain, bone, adrenal glands, lymph nodes, intestine, and others). A 66-year-old man whith a abdominal mass, went to our hospital with a colonic tumour diagnosis. The patient was submitted to a surgery, with resection of the rigth colon. The disease was invading a portion of the retroperitoneal tissue that was removed. The histopatologic study showed the pathognomonic sign of malakoplakia (Hansenmann cells and Michaelis-Gutmann bodies). Norfloxacin have been used to the complementar treatment with total cure of the patient

Malacoplasia do intestino grosso, bexiga e retroperitônio: relato de caso / Malacoplakia of large bowel, bladder and retroperitoneum: report of a case

Os autores relatam um caso de malacoplasia acometendo o intestino grosso, bexiga e retropertônio, doença rara, principalmente pelo comprometimento de mais de um órgäo. Trata-se do segundo caso observado em nosso Serviço, envolvendo os mesmos órgäos. Estudam os meios diagnósticos e terapêuticos e däo ênfase à associaçäo sulfametoxazol-trimetoprim (SMZ-TM) e ácido ascórbico, que se mostrou eficiente a longo prazo na resoluçäo da enfermidade

Malacoplaquia en colon y retroperitoneo: informe de dos casos / Colonic and retroperitoneal malakoplakia: a report of two cases

Se informan dos pacientes con malacoplaquia extravesical. El primero corresponde a un caso de autopsia de malacoplaquia colónica asociada a un adenoma velloso que se manifestó por dolor lumbar, rectorragia y fiebre en un hombre de 34 años con neurofibromatosis. El segundo a una mujer de 43 años con manifestaciones clínicas vagas e imagen tomográfica de tumor retroperitoneal que fue sometida una lumbotomía. El diagnóstico histopatológico inicial fue de sarcoma de bajo grado. La información obtenida de la revisión de la literatura nos permitió identificar 58 casos de malacoplaquia colónica, unicamente uno asociado a un adenoma velloso y cuatro de localización retroperitoneal. No existe un cuadro clínico característico de la malacoplaquia intestinal o retroperitoneal. Con frecuencia las imágenes radiográficas muestran lesiones de bordes irregulares, por lo que ocasionalmente la impresión clínica es de neoplasia maligna. Esto complica la interpretación morfológica. Por ello, es necesario informar los casos de esta entidad con el objeto de crear experiencia en su diagnóstico

Malacoplaquia renal unilateral en un paciente pediátrico / Renal malacoplakia: study in a pediatric patient

La malacoplaquia renal es una rara enfermedad inflamatoria, granulomatosa, descripta inicialmente por Michally Goodman en 1902. Hasta 1984 se habían descripto en la literatura aproximadamente 200 casos. Se presenta una niña de 10 años, estudiada en 1988 y controlada hasta la actualidad en nuestra Institución. Ingresa con una infección urinaria a Scherichia Coli. Se le realiza diagnóstico ecográfico de alteraciones renales derechas, compatibles con una nefritis bacteriana. Se completan los estudios con urograma excretor y tomografía computada. La paciente es nefrectomizada, teniendo diagnóstico anatomopatológico de malacoplaquia renal. Siendo la ecografía un método de screening utilizado diariamente en los niños con infección urinaria, consideramos de importancia conocer esta rara enfermedad, dado que el tratamiento definitivo es la nefrectomía
