RESUMO
Cystic lesions in the retrorectal or presacral space present a broad differential diagnosis. Rare but typical lesions at this site are those related to embryonic development, which are the most frequent presacral congenital lesions in adults. Amongst these tumors, epidermoid cysts and cystic hamartomas are the most common lesions. Cystic masses, which are asymptomatic in approximately 50% of the cases at diagnosis, may show complications such as infection or malignant degeneration. Initial diagnosis is based on imaging techniques although definite lesion characterization, essential due to their malignancy risk, is given by the pathological analysis of the surgical piece.

Las lesiones del espacio retrorrectal o presacro plantean un amplio diagnóstico diferencial. Una patologíatípica aunque rara de esta localización son las masas quísticas relacionadas con el desarrollo embrionario, que constituyen las lesiones congénitas presacras más frecuentes en el adulto. De éstas, los quistes epidérmicos y los hamartomas quísticos son las más comunes. Asintomáticas hasta en la mitad de los casos al diagnóstico, las masas quísticas pueden presentar complicaciones infecciosas e incluso degeneración maligna. El diagnóstico inicial se basa en las pruebas de imagen, aunque la caracterización definitiva, de gran importancia dado el riesgo de malignización, viene dada por la anatomía patológica de la pieza quirúrgica. Presentamos dos casos clínicos de lesiones quísticas retrorrectales diagnosticadas en nuestro centro (AU)

Large intestine infection due to spirochetes was described in 1967 and is mainly related to two pathogens, Serpulina pilosicoli and Brachyspira aalborgi. Clinically, infection presents as diarrhea and/or rectorrhagia and is more frequent among homosexuals. Its prevalence is difficult to estimate but significant differences have been described according to the socioeconomic level of the area studied. We describe three cases of diarrhea due to spirochetes, which are of interest due to the lack of published cases in Spain. Based on these cases, we describe the main characteristics (morphological, therapeutic, etc.) of this infection.
