Background:
Pulmonary lymphomatosis carcinomatous (PLC) is a special type of pulmonary metastasis of carcinoma. It is easy to be misdiagnosed as other pulmonary diseases. In this study the clinical manifestation of PLC is analyzed to improve the understanding of the clinical manifestations of PLC and to avoid or reduce misdiagnosis.
Methods:
A retrospective analysis was performed on 7 PLC patients with autopsy diagnosis in our hospital, their clinical and radiological characteristics were analyzed and summarized.
Results:
The clinical manifestations of PLC mainly expressed as dry cough and dyspnea. Increased lung markings by X-ray were observed with scattered small reticulonodular and fibrous shadow. None of the 7 cases had been diagnosised as PLC before death.
Conclusions:
PLC should be considered when malignant tumor patients are companied by respiratory symptoms, such as cough and dyspnea.
