Synchronous Pulmonary Malignancies: Atypical Presentation of Mantle Cell Lymphoma Masking a Lung Malignancy
نویسندگان
چکیده
We present a case of a pleural space malignancy masked by an atypical presentation of mantle cell lymphoma. Our patient presented with a large pleural effusion and right sided pleural studding, initially attributed to a new diagnosis of mantle cell lymphoma. Rare atypical epithelial cells were also seen amongst the clonal population of lymphocytes. The patient lacked systemic manifestations of mantle cell lymphoma and did not improve with chemotherapy. A pleural biopsy ultimately revealed the presence of an undifferentiated carcinoma, favoring a lung primary. A discussion of synchronous pleural space malignancies involving lymphomas is given.

Synchronous malignancies with an esophageal malignancy are not uncommon. However synchronous esophageal and renal cell carcinoma (RCC) is rare with only 11 cases reported in the world literature, the esophageal malignancies being adenocarcinomas or squamous cell carcinomas. Here, we report the first case of synchronous small cell carcinoma (SCC) of the esophagus with a RCC. SCC of the esophagus...

Extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue type (extranodal MZL) is a distinct subgroup of non-Hodgkin's lymphoma. Pulmonary extranodal MZL is a rare entity and accounts for less than 0.5% of primary pulmonary malignancies. Only a few cases of simultaneous occurrence of lung cancer and pulmonary extranodal MZL have been reported. A 60-year-old woman was referr...
