- PURPOSE: There is no specific treatment guidelines for Henoch-Schonlein (HS) nephritis. Therefore we performed this study to observe the effect of long term steroid therapy combined with azathioprine METHODS: Treatment protocols; 1) Steroid pulse therapy: methylprednisolon 30 mg/kg/dose, maximum 1 gm, intravenously 6 times for alternate day. 2) Oral steroid was given 2 mg/kg/day for 1 month, 1 mg/kg/day for following I month and alternate day oral steroid combined with azathioprine 2 mg/kg/day for 2 years. RESULTS: Time period from HSP to onset of HS nephritis was between 2 weeks to 5 months with mean 7.4+/-7.4 weeks. Clinical remission were seen in 4 cases out of 5 (80%). Mean time period with disappearance of proteinuria and microscopic hematuria were 5+/-2.4 month and 13.3+/-2.9 month respectively. On pathologic findings by ISKDC, 3 cases were grade IIIb, 2 cases were grade IV in first kidney biopsies and showed pathologic improvement in follow up kidney biopsies after 2 years treatment. CONCLUSION: As there no definitive treatment for HS nephritis so far, our study of long term oral steroid therapy with azathioprine was effective in clinical and histologic aspect. Therefore further study in HS nephritis with in a large group will be needed in the future.

- Well differentiated fetal adenocarcinoma of the lung is a subtype of pulmonary blastoma. In this report, CT-guided fine needle aspiration smears were performed at the right upper lobe of the lung in a 45 year-old male patient who had the smoking history of one pack per day for 25 years. The smears disclosed round, papillary, and tubular patterns of cell clusters. The individual cells had relatively uniform, small to medium sized nuclei without nucleoli, and showed vesicular or eosinophilic cytoplasm with indistinct cell border. The morules were seen in the central area of papillary clusters. They were composed of two cell types, outer single layered cuboidal cellular lining and central three-dimensional cluster of cells simulating fetal lung.
These cytologic features need to be differentiated from usual pulmonary adenocarcinoma, carcinoid, and pulmonary blastoma. On histologic findings, the tumor arised in the bronchial epithelium. And the tumor cells had abundant intracytoplasmic glycogen with neuroendocrine feature on histochemical study. In addition, the multiplicity of this tumor is the unique point comparable to the previous reports.
