A case of Lennert's lymphoma in a postgastrectomy patient under strict observation for gastric cancer is descrived with a review of the literature.
A 67-year-old man was admitted to the hospital because of a walnut-sized mass in the left axilla. The mass was relatively hard, painless, and poor in movability. It has a smooth surface.
We suspeced lymph node metastasis of the gastric cancer or malignant lymphoma. Biopsy cytology was performed, but no definite diagnosis was made.
A resection of the left axillar tumor was performed. Histological diagnosis was made as of Lennert's lymphoma.
Anticancer chemetherapy was added following the surgical treatment, and he has been disease-free. The relationship between gastric cancer and Lennert's lymphoma is still obscure. No additional case report has been seen in the literature as far as we could review. This case is extremely rare.
