Primary gastric Hodgkin lymphoma and metachronous early gastric carcinoma: a case report

Primary Gastric Hodgkin lymphoma is seen very rarely. Primary gastric Hodgkin lymphoma and gastric carcinoma in same patient is very very rare entity. Almost all of the primary gastric lymphoma cases are non-Hodgkin lymphoma type. We report the case of 45-year-old man with 3-month history of abdominal pain and weight loss. Upper gastrointestinal endoscopic examination revealed an ulcerated polypoid mass on greater curve of stomach and histopathological examination of biopsy showed adenocarcinoma. After near total gastrectomy, gastric Hodgkin lymphoma diagnosis was made, and postoperative 4 courses of doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD) regimen were administered, and then total 3,600 cGy radiotherapy was delivered. After 7 years, during control examination, early gastric carcinoma was diagnosed. Our case is very rare entity of gastric Hodgkin lymphoma and metachronous gastric carcinoma. This case also shows the importance of follow-up of patients not only for the relapse of primary disease but also for the development of secondary malignancy which can be diagnosed at early curable stage.
