Background: The presence of a lymphoma associated with a solid synchronous neoplasm or collision neoplasm has been rarely in the literature, and a detailed characterization of these cases is lacking to date.Objective: To describe the main clinicopathological features of synchronous/collision tumors.Methods: A systematic search in PubMed, Scielo, and Virtual Health Library literature databases for cases or case series of synchronous or collision lymphoma and other solid neoplasms reported up to March 2021 was performed. Three reviewers independently screened the literature, extracted data, and assessed the quality of the included studies. The systematic review was performed following the Preferred Reporting Items for Systematic Meta-Analyses guidelines.Results: Mean age of patients was 62.9 years (52.9% men). A total of 308 cases were included (62% synchronous and 38% collision). The most frequent location of both synchronous and collision tumors was the gastrointestinal tract with the most common solid neoplasm being adenocarcinoma, and the most frequent lymphoma diffuse large B-cell lymphoma (21.7%) and mucosa-associated lymphoid tissue lymphoma (20.4%). Of the total number of mucosa-associated lymphoid tissue lymphomas and gastric adenocarcinomas, the presence of Helicobacter pylori infection was documented in 47.3% of them. Only 2% of all cases had a previous history of lymphoma. Thus, in most cases (98%), lymphoma was discovery incidentally. In addition, nodal lymphoma was associated with metastasis in 29 (9.4%) cases as collision tumor, most commonly (90%) in locoregional lymph nodes of the solid neoplasm. Conclusions:The frequent association of some type of B-cell lymphoma and adenocarcinoma in synchronous/collision tumors of the gastrointestinal tract points to common pathogenic mechanisms in both neoplasia, particularly related to chronic inflammation in this location. In most cases, lymphoma identified in locoregional lymph nodes or distant of a carcinoma seems to represent an incidental finding during the carcinoma diagnostic/therapeutic approach. A synergy between carcinoma and lymphoma (involving inflammation and immunosuppression mechanisms) may favor tumor progression and dissemination. A better understating of the interactions lymphoma/carcinoma in the setting of synchronous/collision tumors may help to improve patient management and prognosis.

BackgroundPatients with malignant melanoma have an increased risk of developing secondary hematologic malignancy, and patients with hematologic malignancies have an increased risk of developing melanoma. Rarely, sentinel lymph node biopsies (SLNBs) collected for melanoma staging might harbor lymphoma or even carcinoma, which may represent a second primary malignancy (SPM). Biopsied lymph node(s) might serve as the first site of recognition for a SPM. Yet, there has been little systematic investigation regarding the characteristics of incidental SPMs detected on SLNB for melanoma staging.MethodsA series of cases of lymphomas and carcinomas were detected incidentally during SLNB for melanoma staging from two tertiary academic centers between 2000 and 2021.ResultsFifteen cases of incidentally detected SPMs were reviewed, comprising 12 lymphomas and three carcinomas. The most common incidentally detected second malignancy was chronic lymphocytic leukemia/small lymphocytic lymphoma (60%, 9/15). There were three cases of incidentally detected metastatic carcinoma. Of all incidentally detected malignancies, 2/3 carcinomas and 4/12 lymphomas represented first‐time diagnoses of SPM in a melanoma patient. Forty percent of cases (6/15) also harbored metastatic melanoma in the sentinel lymph node.ConclusionsIt is possible to incidentally detect SPMs in SLNBs for melanoma staging. Early detection of SPMs in melanoma patients has implications for the treatment of both incidental SPM and melanoma.
