PURPOSE: To evaluate the CT findings of focal organizing pneumonia and to correlate them with pathologic findings to help differentiating from lung cancer. MATERIALS AND METHODS: We evaluated radiologic and pathologic findings of five patients with solitary pulmonary nodule which were confirmed as focal organizing pneumonia pathologically. RESULTS: On CT scan, focal organizing pneumonia had irregular margin contacting the pleura in all five cases. The shape of the nodules were spherical to wedge or elliptical and the size from 3.5cm to 5.5cm (average 4.2cm) in largest diameter. On postcontrast CT scan, all nodules showed enhancement and four cases showed central low density components. Two nodules contained air within the nodule. In four cases, pleural changes such as effusion and/or focal thickening were noted. No lymphadenopathy was found in all cases. Pathologically, the enhancing portion on CT showed findings of organizing pneumonia such as granulation tissue with fibroblast proliferation in alveolar space and interstitial thickening. The central low density areas on CT were due to ischemic necrosis, abscess and exudate, transudate and infiltration of foamy histiocyte. CONCLUSION: The possibility of focal organizing pneumonia should be considered when peripherally located solitary pulmonary nodule had enhancing component with no combined lymphadenopathy on CT scan.

Herein, polyorchidism possessing of more than the usual number of testicles, which was found in two patients, is reported. Both patients had three testes, and one presented with painful swelling of the right scrotum caused by torsion of the testis and the other revealed a non-palpable testis in the right hemiscrotum. Both patients were managed surgically with orchiopexy and an orchiectomy, respectively, followed by the insertion of an artificial testis.

Peripheral blood stem cells(PBSC) were collected for autologous transplantation for the first time in Korea wish Fenwal CS-3000 Plus blood cell separator. Twenty-nine procedures were performed for 7 patients without any incidents. GM-CSF(400ug) was administered daily for 5 days before PBSC collection and the collections were performed 3-6 successive days. A total of 3.5-11.4 x 109 mononuclear cells(MNCs) were collected from 7,000mL blood processed per procedure. The number of MNCs collected was mainly dependent on the concentration of MNCs in patient's blood(r = 0.68, p<0.01). We concluded that the PBSC trans plantation program could be set up without difficulty in Korea since the Fenwal CS-3000 Plus blood cell separator is already available in many institutions and the procedure used in this study is easy to follow.
