The synchronous diagnosis of colorectal malignancy and lymphoma is rare. We report five cases demonstrating this phenomenon with varying presentations, demonstrating the need for vigilance for the possibility of dual pathologies. In two patients colorectal malignancy staging CT scans identified pathological lymphadenopathy consistent with lymphoma. A further two patients had an incidental lymphoma on histological examination of the colorectal malignancy specimen. The fifth patient was found to have suspicious superior mesenteric lymph nodes at laparotomy. Histology confirmed two nodular lymphocyte-predominant Hodgkin lymphomas, a lymphocytic-rich classical Hodgkin's lymphoma, a diffuse large B-cell lymphoma and a B-cell follicular lymphoma.

Pulmonary metastasectomy in patients with pulmonary metastases from primary colorectal cancer seems to improve survival in properly selected patients. Therefore, pulmonary metastasectomy has been inco...
The synchronous occurrence of two different neoplasias is an uncommon event, which may arise between tumors originating in the same organ or in cancer-to-cancer metastasis. We report a rare case of ch...
Burkitt's lymphoma is an undifferentiated non-Hodgkin's B-cell lymphoma. Three clinical subtypes are recognized: African (endemic), American and other areas (sporadic) and human immunodeficiency virus...
Because colonoscopy after colorectal cancer surgery is important for detecting synchronous or metachronous colorectal neoplasms, we designed this study to investigate, by using postoperative colonosco...

The follow up of colorectal cancer after curative surgery has to find loco-regional relapses or synchronous metastases, and to detect adenomas and new cancer on the rest of the colon. The...

Clusters of colonic crypts that appear different from the surrounding mucosa when visualized after staining. They are of interest as putative precursors to colorectal adenomas and potential biomarkers for colorectal carcinoma.
Tumors or cancer of the COLON or the RECTUM or both. Risk factors for colorectal cancer include chronic ULCERATIVE COLITIS; FAMILIAL POLYPOSIS COLI; exposure to ASBESTOS; and irradiation of the CERVIX UTERI.
Aggressive T-Cell malignancy with adult onset, caused by HUMAN T-LYMPHOTROPIC VIRUS 1. It is endemic in Japan, the Caribbean basin, Southeastern United States, Hawaii, and parts of Central and South America and sub-Saharan Africa.
B-cell lymphoid tumors that occur in association with AIDS. Patients often present with an advanced stage of disease and highly malignant subtypes including BURKITT LYMPHOMA; IMMUNOBLASTIC LARGE-CELL LYMPHOMA; PRIMARY EFFUSION LYMPHOMA; and DIFFUSE, LARGE B-CELL, LYMPHOMA. The tumors are often disseminated in unusual extranodal sites and chromosomal abnormalities are frequently present. It is likely that polyclonal B-cell lymphoproliferation in AIDS is a complex result of EBV infection, HIV antigenic stimulation, and T-cell-dependent HIV activation.
