80 cases of Cysticercosis were studied and analysed, which were diagnoses by biopsy at Seoul National University in the past three years from January-1978 to March-1980. The results were summerized as follows. 1. The relative incidence ratio of cysticercosis among 18,941 surgical specimens was 0.42%. 2. The age group between 11 and 50 years old occupied 87.5%. 3. Of the 80 cases, there were 38 males and 42 female patients, without significant sex predominence. 4. The common sites of cysticercosis were upper extremities (35.0%) and anterior surface of the trunk (37.5%) 5. Epidemiologically, there was marked predominence of rural area over urban area. 6. There were 8 cases (10%) of definite cerebral cysticercosis and 4 cases (5%) of suspicious cerebral cysticercosis. 7. In the cases of nodular masses of extremities, the parasitic infection, especiaily cysticercosis celluiosae, must be included in differential diagnosis distinguished from other soft tissue tumors.
