A rare case of colonic malakoplakia at the bottom of an adenoma mimicking an invasive carcinoma.

We present the case of a 47-year-old man with a history of refractory multiple myeloma who was referred to our hospital for the presence of a colonic lesion suspected of having signs of deep submucosal invasion. After a surgical resection, the histological study revealed that it was a case of malakoplakia that had developed at the base of a tubular adenoma.

[Primary choriocarcinoma of the stomach. A case report].

Primary gastric chorioadenocarcinoma (PGC) constitutes less than 1% of all gastric cancers; it is more common in men. Approximately one third of patients already have metastatic disease at the time of diagnosis. We present the case of a 70-yearold male patient, diagnosed as gastric adenocarcinoma in anthropylorus, who underwent radical distal gastrectomy.

Primary squamous cell carcinoma of the sigmoid colon: a case report and literature review.

Primary squamous cell carcinoma of the colon is extremely rare. The etiology is poorly understood, and currently, there are different hypotheses about the origin of this malignant neoplasm. Here, we report a case of an 87-year-old male with a moderately-differentiated nonkeratinizing squamous cell carcinoma of the colon.

[Impact of the Epstein Barr virus on gastric cancer in Peru].

Unlabelled: Epstein Barr Virus (EBV) is responsible of 10% of Gastric Cancer (GC), correlating with better survival rates. In Peru, there were not studies about prevalence and clinical characteristics of CG EBV positive.

Objective: Determine prevalence and clinicopathological characteristics of GC EBV positive.
