Pulmonary adenocarcinoma of fetal type is a very uncommon tumor of the lung which simulates an early stage of lung differentiation. This is a primitive appearing epithelial tumor similar to the epithelial component of pulmonary blastoma but lacking the sarcomatous features. Since the report of Kradin et al, 8 more cases have been reported by a variety of name. These tumors are composed of glycogen-rich, non-ciliated tubular epithelial cells forming irregularly shaped tubules or arranged in a papillary pattern. A very remarkable findings of this tumor is the presence of endocrine cells which is confirmed by argyrophilia, immunohistochemistry or electron microscopy. We experienced a case of this tumor which showed hepatocytoid differentiation in addition to the characteristic histologic findings. Immunohistochemical studies performed on a resected tumor tissue showed immunoreactivity for alpha-fetoprotein, neuron-specific enolase and somatostatin, and endocrine type granules were found ultrastructurally. Although this tumor seems to have a relation with pulmonary blastoma in its histology, immunohistochemistry and ontogeny, a distinction between these should be attained because the average survival of the former group is longer as 23 months, while that of the latter is only 4 months.

Mesoblastic nephroma is an important differential diagnosis of a renal mass occurring in the neonatal period or in early childhood. It is a rare monomorphous congenital renal neoplasm most commonly recognized during the first 3 months of life. With the widespread application of ultrasound imaging, many cases are recognized prior to birth. We report a case of mesoblastic nephroma detected by ultrasonograph at 36 weeks of intrauterine fetal life and removed after birth. It showed a well circumscribed, grayish white, solid mass measuring 4x3x2 cm. The tumor was predominantly a classic type with a focal cellular pattern. Immunohistochemical and electron microscopic studies were done.

Following chemotherapy and radiation treatment for infiltrating ductal carcinoma of the left breast, a 50-year-old woman presented with a child's palm sized, crusted patch and surrounding peanut sized granulated nodules on the lesion, which was diagnosed as primary cutaneous aspergillosis caused by Aspergillus fumigatus. No evidence of involvement of other organs or of systemic dissemination by Aspergillus femigatus was found. Also the patient exhibited no other apparent systemic immunologic defects. Extensive excision were performed and the patient received treatment with amphoteriein B. No evidence of recurrent fungal infection was noted during 6 months of follow-up.
