Abstract: Objective To study the clinical characteristics, diagnosis, treatment and prognosis of primary pulmonary peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). Methods Two cases of primary pulmonary PTCL-NOS were studied and relevant literature were reviewed. Results Case 1 diagnosed as primary pulmonary PTCL-NOS was a 44 years old woman and disease progressed after GLD (Gem+L-OHP+DXM) chemotherapy regimen. At last, the patient died of respiratory failure after one month. Case 2 diagnosed as primary pulmonary PTCL-NOS was a 46 years old man and reach partial response after CHOP regimen, and still alive now.Conclusion Primary pulmonary PTCL-NOS is very rare. It is easy to be misdiagnosed due to non-specific clinical and imaging manifestations. Acquiring enough tissue specimens for pathologic examination is the key to a definitive diagnosis. At present, there is no standard chemotherapy regimen for these patients, the prognosis is relatively poor.
