Successful Treatment of Coexistence of Diffused Large B Cell Lymphoma and Lung Adenocarcinoma, a Case Report

Case of a lung collision tumor consisting of squamous cell carcinoma of the lung and diffuse large B-cell lymphoma

Among the reports of malignant collision tumors, collision tumors consisting of lung cancer and malignant lymphoma are extremely rare. We report case of a lung collision tumor consisting of squamous cell carcinoma of the lung and diffuse large B-cell lymphoma.

Synchronous primary pulmonary adenocarcinoma and extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue: A case report and literature review

RATIONALE

Synchronous pulmonary lymphoma and carcinoma is relatively rare. And synchronous pulmonary lymphoma and adenocarcinoma in the same site is extremely rare.

PATIENT CONCERNS

We presented a 69-year-old female with a tumor mass in right upper lung.

DIAGNOSIS

Pathological and immunohistochemical findings revealed lung adenocarcinoma and extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue.

INTERVENTIONS

The patient received thoracoscopic guided right upper lobectomy and focal lymph node dissection after systemic anesthesia. Besides, 6 cycles of chemotherapy were given based on meprednisone, gemcitabine and cisplatin in local hospital.

OUTCOMES

In the 12-month follow-up, the patient was still alive with no local recurrence, metastasis and lymph node involvement.

LESSON

A comprehensive literature research was performed, and 6 cases of synchronous pulmonary lymphoma and adenocarcinoma in the same site and 10 cases in different sites were identified since 2000. Most patients with synchronous pulmonary lymphoma and carcinoma were middle-aged and elderly with the median age was 64 years presenting a male predisposition. The most frequent type of primary pulmonary lymphoma was B-cell non Hodgkin lymphoma, especially mucosa-associated lymphoid tissue lymphoma, and the lung cancer is predominantly adenocarcinoma.

Coexistence of colon adenocarcinoma, diffuse large B-cell lymphoma, and myelodysplastic syndrome: A case report

RATIONALE

Cases of coexistence of 2 cancers, such as colorectal cancer and diffuse large B-cell lymphoma (DLBCL), colorectal cancer and myelodysplastic syndrome (MDS), and DLBCL with MDS, have been reported, whereas the coexistence of 3 different cancers in a patient is extremely rare. Here we report a case of co-occurrence of colon adenocarcinoma, DLBCL, and MDS in a 78-year-old Chinese man.

PATIENT CONCERNS

He presented to our hospital with palpable lumps in the abdomen without any of the following symptoms including abdominal pain, fever, contact pain, tenesmus, changes in bowel habits and shape, nausea, and vomiting.

DIAGNOSES

The patient was first diagnosed with sigmoid colon adenocarcinoma and DLBCL in the right ascending colon using enhanced computed tomography, colonoscopy, and immunohistochemistry. After resection of the sigmoid adenocarcinoma and DLBCL, MDS was diagnosed according to the results of routine blood tests, bone marrow aspiration smear, and flow cytometry.

INTERVENTIONS

Overall, the patient was treated with surgical resection of the sigmoid adenocarcinoma and DLBCL of the colon, combined with 4 cycles of chemotherapies targeting MDS.

OUTCOMES

Blood test results and follow-up indicated that the treatment regimen showed promising outcomes.

LESSONS

In conclusion, a case of synchronous existence of colon cancer, DLBCL, and MDS is reported, which suggests that careful attention should be paid clinically to checking the state of bone marrow for elderly cancer patients. Efforts are also needed to establish an effective system for distinguishing the origin of multi-existent cancers and to develop effective therapeutic regimens for multi-existent cancers with fewer side effects.

Lymph Node Collision Tumor Consisting of Metastatic Pulmonary Adenocarcinoma and Diffuse Large B-cell Lymphoma

A 67-year-old man presented with a fever and general malaise. Computed tomography showed multiple nodules in the lungs and liver, associated with mediastinal and para-aortic lymphadenopathy. Bone marrow aspiration revealed diffuse large B-cell lymphoma (DLBCL). Renal and liver dysfunction and pancytopenia inhibited chemotherapy administration; the patient subsequently died of multiorgan failure. An autopsy revealed pulmonary adenocarcinoma with metastases to the lungs, liver, and adrenal glands; the DLBCL spread to the liver, spleen, and bone marrow. Adenocarcinoma and DLBCL collision was observed in the mediastinal and para-aortic lymph nodes. This was a rare case of collision metastasis occurring in the lymph node.
