Background:
Seminoma is a rare event in old male population. In this report, we present a rare case of primary seminoma in the lung of a 76-years-old man.
Case Presentation:
The patient was a 76-year-old man admitted with respiratory tract symptom and hemoptysis. The Chest Routine Scan and CT showed there was a consolidation area in the basal segments at the lower lobe of left lung. Bronchoscope also exhibited a neoplasm in left lung. During left lower lobectomy, we found that adherence occurred widely in left thoracic wall, and the pleural membrane was shrinkage. No chemotherapy or radiotherapy was given. Patient was died at 140 days after the surgery mainly due to the dyscrasia and secondary seminoma in left 7th to 9th ribs. Placental alkaline phosphatase (PLAP) and CD117 were found to be positive with immunohistochemical studies. Along with other evidences, this case was identified as the manifestations of seminoma.
Conclusion:
Although primary seminoma of the lung is rare in old male population, the diagnosis should be taken into serious consideration in order to improve the treatment. And in this case, primary lung seminoma is associated with high degree of malignancy and metastasis.
