Analysis of Parasitic Diseases by Biopsy in Kyunghee Medical Center(1972~1983) / 감염

BACKGROUND: Tissue biopsy is of significant importance to the parasitic diseases. This report describes in order to know the species and frequency of human parasitic infection diagnosed by biopsy at the department of anatomical pathology, KyungHee Medical Center. Finally, we estimated the trend of parasitic diseases of tissue in a feature, in Korea. METHOD: 262(0.57%) cases of parasitic infection were reviewed for analysis of the different types of parasitic infection, 45,651 biopsied materials were submitted for routine histopathological examination during a period of 12 years from 1972 to 1983 at the department of anatomical pathology, KyungHee Medical Center. RESULTS: They consisted of 136 cases of cysticercosis, 73 clonorchiasis, 16 amebiasis, 12 paragonimiasis, 9 ascariasis, 9 sparganosis, 4 scabies, 1 taeniasis, 1 enterobiasis and 1 anisakiasis. 136 cases of cysticercosis were mainly of the skeletal muscle and subcutaneous tissue. The 73 cases of clonorchiasis occurred mainly in the liver and gallbladder. In the 16 cases of amebiasis, the liver and the rectum were the main loci. In 12 cases of paragonimiasis, pleura was the main site. CONCLUSION: The frequency of parasitic infections found in biopsied specimens was found to decrease as the years passed by, but some disease such as sparganosis showed a possible increase. Tissue biopsy is an important method for detection of tissue or ectopic parasitic infections.

A Case of Tick Infestation in Chest Wall by Ixodes Nipponensis / 감염

We report herein an unusual case of tick bite. A 56 year old woman complained of erythematous nodular skin lesion on the left upper chest. An excision biopsy specimen of the lesion showed darkish-red nodule, in which there was a tick. It was identified as an adult female of Ixodes nipponensis by the scanning electron microscopic examination.
