[Deep cystic colitis located in a previous surgical anastomosis]. / Colitis quística profunda localizada en anastomosis quirúrgica previa.

Deep cystic colitis is a rare disease of which about one hundred cases have been reported in the medical literature. Two forms are known, segmental and localized, the latter being the most frequent. We offer a case of a patient who developed a picture of deep localized cystic colitis on a previous surgical anastomosis, a very infrequent association. The value of intraoperative biopsy in these cases is discussed. It is necessary to be aware of this entity and its clinicopathologic correlations to differentiate it, especially from the therapeutic and prognostic points of view, from well differentiated colorectal carcinoma and colloid (mucoid extracellular) carcinoma.

[Lymphoma of the cecum]. / Linfoma del ciego.

A description is offered of a toxic and febrile young patient with diarrheic syndrome of twenty days evolution secondary to extranodal lymphoma of cecal location. A concomitant immunity deficit--selective IgA deficit--appeared in the form of chronic mucocutaneous candidiasis and discoid lupus, and in the absence of familial antecedents. As a result of this case study, an association of gastrointestinal lymphoma of unusual location with an underlying immune disorder, the literature was reviewed.
