Abstract:
This clinical and histopathological study was performed with 147 cases of benign mielanocytic tumors and 19 cases of malignant melanomas, which were obtained as surgical specimens from 1974 to 1984 at Department of Clinical Pathology, Catholic Medical College. The results were as follows: 1, In 89 cases of acquired benign melanocytic nevi, the average age of intradermal type(64 cases) was 34. 7 years and that of compound type(24 cases) was 24. 6 years. 2. In 30 cases of congenital nevus, nevus cells were present in the lower two thirds of reticular layer of the dermis in 93. 3% and in the subcutis as well in 3.3%. A case of giant congenital nevus with balloon cell appearance was found. 3. Of the 147 benign melanocytic tumors, a pigmented spindle cell nevus and a desmoplastic nevus were observed. 4. Blue nevi were 11 in number and excised from the face in 7, buttock in 2, shoulder in 1, upper arm in 1, and all were common type histopathologically. 5. Twelve malignant melanornas which were possible to be re-examined histopathologically were composed of 5 nodular type, 3 acral lentiginous type, 1 superficial spreading type and 3 metastatic malignant melanoma.
