Estimated incidence of round ligament varicosities in pregnancy is not known and often times it is confused with inguinal hernia due to their clinical similarities. When a patient is presented with inguinal mass especially in association with varicosity in the genital region or lower extremity, round ligament varicosity must be considered as a plausible diagnosis. Depiction of bag of worms on color Doppler ultrasonography is diagnostic of the round ligament varicosity and it is known to resolve spontaneously following delivery. We report a case of round ligament varicosities that was diagnosed at 29 weeks of gestation with a brief review of the literatures.

Sometimes a pilomatrixoma on upper neck can be misdiagnosed as primary salivary gland tumor, skin adnexal tumor or metastatic carcinoma. On fine needle aspiration cytology(FNAC), characteristic features are ghost cells, basaloid cells, and calcium deposits, among which presence of ghost cells seems to be the key to recognize it. Here we present a cytologically misdiagnosed case of pilomatrixoma. A 32-year-old man presented a subcutaneous mass on the right posterior neck. It has grown slowly for 1 year, and was nontender, well circumscribed, hard, and movable mass. An Initial FNAC yielded only monomorphic population of highly mitotic basaloid cells, without anucleated ghost cells, chronic inflammatory cells or foreign-body giant cells, suggestive of a poorly differentiated carcinoma. However, that was inconsistent with patient's clinical findings. For further correct diagnosis, FNAC was repeated, which yielded the basaloid cells and foreign-body giant cells. The diagnosis of pilomatrixoma could be made and the mass was excised. This case demonstrates that the pilomatrixoma should be considered in the differential diagnosis of subcutaneous aspirates containing not ghost cells but a dominant population of basaloid cells.

The columnar cell variant of papillary carcinoma is a rare tumor of the thyroid, associated with aggressive behavior, early metastasis, and a rapidly fatal course. We present the fine needle aspiration cytologic(FNAC) findings of columnar ceil variant of papillary carcinoma with cytohistologic correlation. In the smears, the tumor fragments showed mainly papillary pattern and a few scattered individual cells were present around the papillary fragments. The tumor cells were columnar or cuboidal and exhibited pseudostratification of the nuclei. The nuclei were oval to elongated with finely stippled chromatin and inconspicous nucleoli. Neither nuclear grooves nor intracytoplasmic inclusion was found. The FNAC diagnosis was consistent with papillary carcinoma. Total thyroidectomy was done and the histologic finding of the mass showed a predominantly papillary and focal solid proliferation of columar cells with marked nuclear pseudostratification. The unique histopathologic features and highly aggressive nature of columnar ceil variant of papillary carcinoma require that this variant should be differeniated from common papillary carcinoma of the thyroid.

Recently, we experienced a case of Angioimmunoblastic T-cell lymphom (AITL) in a 60-year-old man presented with lymphadenopathy, which is first cytological report in Korea. The cytological features showed a heterogeneous population of small to medium-sized lymphocytes, immunoblasts, and plasma cells. Characteristically, there were also a distinct population of follicular dendritic cells admixed with lymphoid cells, forming the so-called dendritic cell-lymphocyte complexes. Histological features showed the classic morphologic features of AITL. Recognition of the characteristic cytological features can suggest the possibility of AITL.

에크린 한공암종은 흔하지 않으며, 전이성 에크린 한공암종은 매우 드문 암이다. 에크린 한공암종은 표피내 한관에서 기원하는 피부 부속기 악성 종양으로, 대부분 에크린 한공암종은 항암치료와 방사선치료에 효과가 없으며, 따라서 유일한 치료방법은 전이되기 전에 국소 및 광범위 절제술을 시행하여야 한다. 본 환자는 두피에 발생한 에크린 한공암종이 점점 진행하여 피부, 림프절, 폐 등으로 전이하였고, 다수의 광범위 절제술에 이어 항암치료와 방사선치료를 받았지만, 결국 폐전이가 악화되어 사망하였다. 본 저자들은 항암치료와 방사선치료에 불응한 에크린 한공암종 1예를 치료에 대한 문헌고찰과 더불어 보고하는 바이다.
재래식 메주에서 분리한 유산균들의 각종 효소활성 및 기능성

전통 재래식 메주 3종을 수집하여 호기성 생균수, 유산균 수, 효모 및 곰팡이의 수를 측정한 결과 각각 10?~10? CFU/g, 106~108 CFU/g, 107~108 CFU/g의 분포를 나타내었고, 일반적으로 메주의 발효에 가장 크게 관여하고 있는 효모 및 곰팡이이 외에도 유산균 역시 메주의 발효에 깊이 관여하고 있는 주요 균주인 것으로 나타났다. 재래식 메주로부터 몇 종의 유산균을 분리한 후, 3종의 우수균주를 선별하여 동정을 실시한 결과, Leuconostoc mesenteroides, Lactobacillus plantarum, Lactococcus lactis로 밝혀졌으며, 이들을 각각 Lm-SMm, Lp-SMm, Ll-GAm로 명명하였다. 3종 유산균의 효소 활성을 측정한 결과, 모두 protease, lipase, α-amylase 활성을 나타내었고 특히 Ll-GAm이 상대적으로 높은 효소 활성을 나타내었다. DPPH를 이용하여 항산화 효과를 측정한 결과, Lm-SMm, Lp-SMm, Ll-GAm은 각각 45%, 48%, 60%의 free radical 소거 효과를 나타내었고, MTT assay를 이용하여 HT-29 인체 결장암 세포 성장억제 효과를 측정한 결과 각각 45%, 67%, 70%의 성장억제 효과를 나타내었다. 따라서 전통메주로부터 분리한 우수한 유산균은 장류제조 산업에 있어서 적용성이 있을 것으로 생각되어지며, 메주 제조에 있어서 스타터로 사용되었을 때 장류제품의 품질을 향상시킬 수 있을 것으로 기대된다. Three kinds of Korean traditional Meju were selected and the counts of microorganisms in these Meju were determined. The counts of total aerobic bacteria, lactic acid bacteria and yeasts and molds were 10?~10?, 10?~108 and 10?~10? cfu/g, respectively in three Meju and lactic acid bacteria were important microorganisms in the fermentation of Meju. Therefore, we isolated three kinds of dominant lactic acid bacteria from these Meju. They were identified as Leuconostoc mesenteroides (98%, Lm-SMm), Lactobacillus plantarum (99%, Lp-SMm) and Lactococcus lactis (98%, Ll-GAm). Then, enzyme activities and physiological functionalities of three lactic acid bacteria were investigated. Protease, lipase and α-amylase activities were detected in three lactic acid bacteria, Ll-GAm showed relatively higher activities than other two lactic acid bacteria. Lm-SMm, Lp-SMm and Ll-GAm showed 45, 48 and 60% of antioxidative activity to 1,1-diphenyl-2-picryhydrazyl (DPPH), and exhibited 45, 67 and 70% of inhibitory effects in HT-29 human colon cancer cells, respectively. These results indicate that three lactic acid bacteria isolated from traditional Meju, especially Ll-GAm are applicable to Meju preparation for soybean paste industry.
