Metastatic anaplastic large cell lymphoma (ALCL) presenting with small bowel perforation

Lymphoma ranks third in the incidence of small bowel malignancy, with adenocarcinoma being the commonest (1). Anaplastic large cell lymphoma (ALCL) constitutes about two percent of adult non-Hodgkin lymphoma and is a subset of T cell lymphoma histology. It has a bimodal age distribution with regard to incidence with the first peak in adolescence and the second after the sixth decade , with a male predominance. Four cases of primary small bowel ALCL presenting with perforation have previously been reported (1). However, literature regarding metastatic ALCL to the small bowel presenting with perforation is scarce. We report a case of metastatic ALCL which presented as jejunal perforation.
