Abstract

Rationale:

Burkitt lymphoma (BL) is an endemic tumor in Africa but rare sporadic cases are diagnosed in Europe.

Patient concerns:

A 60-year-old woman was hospitalized with fulminant hematemesis and a history of recurring melena.

Diagnoses:

The upper gastrointestinal endoscopy revealed a tumor of the antrum.

Interventions:

Emergency gastrectomy was performed.

Outcomes:

Gross findings revealed an ulcerated tumor with elevated margins and several perigastric and extragastric lymph nodes. Histological examination showed proliferation of atypical lymphocytes with a Ki67 index of 100%; they were marked by CD20, CD79a, bcl-6, and CD10 and were negative for CD3, CD5, CD23, TdT, bcl-2, and Cyclin D1. The tumor cells crossed the serosa and presented invasion of the lymph nodes. The patient died 10 days after surgery due to bronchopneumonia and acute renal failure.

Lessons:

In our department, only one gastric BL was diagnosed in a 61 consecutive lymphomas of the gastrointestinal tract (1.64%). Less than 200 reports about gastric-BL have been published to date. This case highlights the difficulty of diagnosis of rare variants of aggressive gastric lymphomas in medium-income countries without screening programmes.
