ABSTRACT
Malakoplakia is a rare chronic inflammatory disease often confused with neoplasia. In this paper we report two cases of pulmonary Malakoplakia, both with typical clinical diagnosis of tuberculosis and lung cancer. A patient with human T-lymphotropic virus type I (HTLV-1) and diagnosis of adult T-cell leukemia/lymphoma, and another patient with human immunodeficiency virus (HIV), which was treated for tuberculosis, but, after pulmonary lobectomy, was evidenced Rodococosis equi, progressed to death...
Malacoplaquia é uma rara doença inflamatória crônica muitas vezes confundida com neoplasia. Neste artigo, relatam-se dois casos de malacoplaquia pulmonar, ambos com quadro clínico sugestivo de tuberculose e neoplasia pulmonar. Uma paciente com vírus T-linfotrópico humano tipo I (HTLV-1) e diagnóstico de leucemia/linfoma de células T do adulto, e um paciente com vírus da imunodeficiência humana (HIV), tratado para tuberculose, mas após lobectomia pulmonar foi evidenciado Rodococose equi, evoluindo para óbito...

Malakoplakia is a rare pseudotumoral inflammatory disease known to affect immunocompromised subjects. We report a 4-year-old boy with malakoplakia of colon who was diagnosed with celiac disease in late infancy; despite aggressive nutritional and medical management for celiac disease, symptoms did not resolve. His nitro-blue-tetrazolium test was compatible with chronic granulomatous disease. In colonic biopsy Michaelis-Gutmann bodies were seen.

Malakoplakia is a rare chronic inflammatory disease, usually involving the urogenital tract. We report a patient who presented with a psoas abscess, and later developed colocutaneous fistula at the site of abscess drainage and multiple spontaneous fistulae away from the site of incision. Histology of the resected specimen showed Michaelis-Gutmann bodies, which are diagnostic of malakoplakia.

A case of a young girl is presented. The main concern was recurrent rectal prolapse not responding to conservative and sclerotherapy. Colonoscopy showed diffuse colitis with superficial ulcerations and pseudopolyps. Colon biopsies finally showed classical features of malakoplakia confirmed by histopathological test. Conservative treatment failed and ultimately proctocolectomy was performed with ileoanal endorectal anastomosis

Reportamos un caso de malacoplaquia del colon que se presentó como hemorragia del tubo digestivo bajo masiva en una paciente femenina de 55 años de edad. Un colon por enema demostró lesiones polipoideas. La colonoscopía reveló nodulaciones pseudo-polipoideas color blanco amarillento, aparentando pequeñas pústulas que se extendían a todo el colon a partir de 2 cm del margen anal. La laparotomía reveló la presencia de masas lobuladas en la luz intestinal y lesiones amarillentas en forma de placas transmulares que infiltraban pared duodenal, así como gran cantidad de ganglios en todo el mesenterio. Realizamos protocolectomía. El estudio microscópico demostró infiltración masiva de histiocitos y numerosos cuerpos de Michaelis-Gutmann. Esta enfermedad se presenta casi exclusivamente en las vías urinarias y es extremadamente rara en el intestino. Enfatizamos en la importancia de un adecuado examen histológico que nos permita un diagnóstico correcto
