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.
