RESUMEN
A 67 year-old male was admitted in the ICU because of multi-organ failure due to sepsis secondary to Fournier's gangrene. He had sustained radical prostatectomy in the last 48 hours. Peritoneal fluid and fatty tissue biopsies grew Aspergillus Fumigatus without concomitant pulmonary involvement. Postoperative acquisition via exogenous and endogenous routes is discussed, as this nosocomial entity is very rarely reported apart from peritoneal dialysis, especially in non-immunosuppressed patients.

A woman, followed for chronic myeloid leukaemia, presented for a routine examination. Her medical history was marked by recurrent Helicobacter pylori gastritis and polymyalgica rheumatica. She was under dasatinib and hormone replacement therapy. At clinical examination, she complained about digestive disorders with altered bowel habits. Biology, including leucocyte count, remained normal. A colonoscopy was performed. Endoscopic examination revealed a colonic mucosa covered by multiple tiny nodular lesions (<5mm) from the hepatic angle to the sigmoid and with an abnormal pattern of vascularisation (Fig. 1). Staged biopsies were taken. Microscopic examination revealed discrete achi-tectural distortions. The stroma contained a mixed inflammatory infiltrate composed of neutrophils, eosinophils and lymphocytes. Immunohistochemistry for CD3, CD5, CD20 and CD79 did not bring arguments for a lymphoma. There were no malignant or dysplastic cells. (Fig. 2). What is your diagnosis?

We report a case of colorectal involvement by a mantle cell lymphoma (MCL) that had been considered before as inflammatory bowel disease. Diagnosis of low-grade MCL can be difficult, and here we highlight the importance of thorough histopathological examination in case of supposed inflammatory bowel disease that does not react to therapy.
