- The dysplastic nevus is a rare form of melanocytic nevus in Korean people. During the past 5 years the authors experienced 5 cases in the St. Mary's Hospital and Kang Nam St. Mary's Hospital. The criteria and the histologic findings of dysplastic nevi are debated in the western literature. Clinically, all cases were greater than 5 mm in size with ill defined irregular borders and irregularly distributed pigmentation. Histopathologically, all cases showed numerous discrete individual nests of melanocytes located in the dermoepidermal junction and the papillary dermis and were characterized by extension of dermoepidermal component of the nevus at the "shoulder" beyond the dermal component of the nevus. There was no cytologic atypia of nevus cells in all cases. Our cases lacked personal or family history of malignant melanoma. Therefore, we believe our cases are nonfamilial, sporadic and benign nevi with no prognostic significance. A brief review of the literature and a discussion on the term "dysplastic" and clinicopathologic correlation are made.

- Wilm's tumor, which is the most mommon renal tumor in childhood, has rarely been reported in adult. Diagnosis of Wilm's tumor in an adult is more apt to be accidental and is almost never suspected in the adult until discovered at operation or necropsy. Recently, we experienced a caseof Wilm's tumor in 20-year-old female patient with chief complaints of right flank pain and he maturia for two months. Renal angiogram revealed a huge renal mass replacing the upper portion of the right kidney. Nephrectomy was done under the impression of renal tumor. Grossly, the tumor was rather soft and relatively well circumscribed, measuring 13 x 8.3 cm in dimension with adhesion to renal capsule and perirenal adipose tissue. The cut surfaces revealed grayish brown in color with areas of multifocal necrosis and hemorrhage. Histologically, the tumor was composed of mainly ovoid or polygonal shaped undifferentiated blastemal cells with large areas of necrosis.
