Coexistence of malakoplakia and multifocal diffuse large B cell lymphoma of colorectum.
We report a case of concurrent multifocal diffuse large B cell lymphoma and malakoplakia of colorectum in a 36-year-old man presenting with recurrent bloody diarrhoea. Malakoplakia has been described in association with a variety of malignant and nonmalignant conditions. To the best of our knowledge, this is the third report of coexistence or association of malignant non-Hodgkin lymphoma and malakoplakia in the literature, and the first report ever in the colorectum.
