OBJECTIVETo report a case of rectal non-Hodgkin lymphoma with concomitant rectal adenocarcinoma.

METHODSClinical records of a 71 years old male patient with rectal non-Hodgkin lymphoma with concomitant rectal adenocarcinoma admitted on May 19, 2010 to the First Affiliated Hospital of Sun Yet-sen University were retrospectively reviewed. Clinical manifestations, diagnosis, and treatment as well as postoperative pathology were summarized.

RESULTSThe preoperative diagnosis of the patient was severe atypical adenomatous hyperplasia with focal carcinogenesis, and the preoperative staging was T2N0-1M0. The patient underwent a Parks procedure (rectal resection and colo-anal anastomosis) and subtotal resection of left lateral liver. The operation was successful, postoperative recovery uneventful. Postoperative pathology showed moderately differentiated tubular adenocarcinoma with deep muscular invasion, and non-Hodgkin lymphoma with marginal zone cell. Both the distal and proximal resection margins were negative and no vascular and neural invasion were seen. Immunohistochemical staining indicated L26(+), Bcl-2(+), Bcl-6(+), CD3(-), CD23(-), CK epithelial cells(+), and M-CEA luminal border(+). The pathological and immunohistochemistry results of liver specimens showed hepatic mucosa-associated marginal zone lymphoma.

CONCLUSIONSRectal adenocarcinoma and lymphoma occurring at the same site simultaneously is extremely rare with unique pathologic features.

Gingival hyperplasia is a frequent complication in transplant patients who receive cyclosporine or calcium channel blockers. We studied an unusual case involving a renal transplant recipient with post-transplant non-Hodgkin's lymphoma that manifested as gingival hyperplasia. We initially consider that it was a side effect of cyclosporine and nifedipine. The lesion did not respond to dose reductions or the withdrawal of cyclosporine and nifedipine, and the gingival hyperplasia progressed in a localized fashion, becoming ulcerated and bleeding easily. Histological examination revealed the presence of malignant lymphoma.

The aim of this study was to investigate the mechanism, susceptibility, (18)F-FDG positron emission computerized tomography ((18)F-FDG PET/CT) features and the treatment of therapy-related acute myeloid leukemia. One patient with NHL was affected with t-MDS after treatment and then progressed to t-AML. The clinical data including bone marrow cell morphology, flow cytometry, karyotype and PET/CT features were analyzed. The results showed that the primary treatment for NHL refers to varieties of cytotoxic drug such as cyclophosphamide-hydroxydaunomycin-oncovin-prednisone (CHOP) chemotherapy. The interval time from the chemotherapy of NHL to the occurrence of t-MDS was 105 months and t-MDS progressed to AML-M(2) in 2 months. Karyotype analysis results of t-MDS and t-AML were normal. (18)F-FDG PET indicated that the FDG uptake in the bone raised diffusely. The patient showed complete response after second-line therapy (CAG regiments). In conclusion, the occurrence of t-AML/MDS may be associated with the application of the cytotoxic chemotherapeutics. (18)F-FDG PET may be an indicator predicting the transformation of t-MDS to t-AML.
