I and 2.) The pathoIogica1 diagnosis was giant hemoIymph node.* The first follow-up visit was March 2, 1957. The patient was re-examined and found to be entireIy free of symptoms reIative to dysphagia. His weight remained constant and he was eating soIid food. An inguina1 hernia found at this time was repaired without complication. From June 14, 1957, through JuIy 14, 1959, the patient was seen on five separate admissions. He had no compIaint of dysphagia and examination faiIed to revea1 a recurrence. He was found to have arterioscIerotic heart disease with right bundle branch bIock, functiona capacity (grade 2) and moderateIy Iimited activity. There were no aberrations of the hemogram on any admission and eosinophils varied from z to 8 per cent.
from the right posterior side of the superior mediastinum. This tumor was situated above the azygos vein and posterior to the esophagus. SeveraI Iarge bIood vesseIs entered the capsuIe which were ligated before removing the mass. PostoperativeIy, the Iung expanded we11and the patient was ambuIant in a few days. He was discharged from the hospital on May 24, 1956. The pathology section reported that, grossly, the tumor was we11encapsulated, IobuIated and soft, and measured 7.0 by 6.0 by 4.0 cm. The coIor was pinkish red and cross section showed it was divided by fibrous septa. MicroscopicaIIy, the capsuIe was we11 defined and moderateIy vascuIar. There was no eIastic tissue or smooth muscIe tissue. The tumor was divided into irregular Iobules by fibrous trabecuIae. The capsule was pierced by bIood vesseIs. AIong the trabeculae were communicating sinuses fiIIed with blood ceIIs and lymphoid eIements. The Iymphoid tissue was predominantIy made up of smaI1 mature Iymphocytes. There were scattered atypica1 centers that resembled Malpighian bodies. Other cells present were eosinophils, poIymorphonucIear Ieukocytes and occasiona Iarge mononucIear ceIIs. (Figs.
SUMMARY
There have been six previous cases of giant hemoIymph node of the mediastinum reported * SIides were reviewed by D. A. C. Broders and the diagnosis corroborated.
