[Mediterranean lymphoma in Peru. Its treatment with oral oxytetracycline].

A new Peruvian case of malabsorption associated with primary diffuse lymphoma of the small bowel and mesenteric lymph glands is reported, having found no alpha chains either in blood or in urine. Like in most of the 8 previous cases, medium oral doses of oxytetracycline supressed diarrhea, markedly atenuated steatorrhea, restored the sense of well-being to the patient, and significantly increased his body weight. Critic is made on the denominations "mediterranean lymphoma" and "primary upper small intestinal lymphoma" ("PUSIL") that have been inappropriately assigned to the condition.
