Pigmentary demarcation lines are borders of abrupt transition between more deeply pigmented skin and that of lighter pigmentation. We describe two patients with pigmentary demarcation lines associated with pregnancy symrnetrially involving the buttocks and flexor as jects of legs. Hormonal changes in pregnancy and compression by the enlarged uterus of Sl and S2 peripheral nerves may be responsible for these changes.

PURPOSE: In young male patients who suffered several kinds of trauma with subsequent suspicious reflex sympathetic dystrophy syndrome, we performed three-phasic bone scan in order to investigate its usefulness. MATERIALS AND METHODS: Patients with narrow range of age (21-25. mean 22.8+/-1.3, all male) were included with suspicious reflex sympathetic dystrophy syndrome of 12 feet and 5 hands. Only one was bilateral feet case and 16 were ipsilateral (Rt:13, Lt:3). The etiologic traumas were 4 fractures, 4 sprains, 3 blunt trauma, 2 cellulitis, 1 tendon tear, 1 crush injury, 1 overexercise, and 1 unknown. Radiologically 3 showed osteoporotic changes. Three-phasic bone scans were performed 21.2+/-7.3wks after trauma. RESULTS: According to symptom complex, confirmatory reflex sympathetic dystrophy syndrome 4 cases and suspicious 13 were analyzed. All confirmatory cases (100%) showed increased uptake at delay phase with periarticular accentuation. Of confirmatory 4 cases, 2 showed increased uptake in all three phases (perfusion: P, blood pool: B, and delay: D), and other 2 revealed decreased P but, both increased B and D. Of suspicious 13 cases, 9(69.2%) had increased D (4 periarticular and 5 focal), 2 decreased D, and 2 symmetric D. In 12 foot cases, so-called weight bearing patterns - increased contralateral sole at P and B - were revealed in 7(58.3%). CONCLUSION: Diffuse periarticular increased uptake at delay phase of three-phasic bone scan was a compatible finding to reflex sympathetic dystrophy syndrome in young male patients whose symptom complex strongly designated post traumatic reflex sympathetic dystrophy syndrome.

The cytologic findings in fine needle aspiration of a case of myxoid liposarcoma of the mediastinum are described. The smear and cell block of the aspirate revealed solid clusters with background of amorphous material and scattered single tumor cells. The clusters were moderately cellular and consisted of atypical lipoblasts in varying stages of differentiation and delicate plexiform capillaries. Good correlation was found between the histologic and cytologic findings in the fine needle aspirates. The differential diagnosis between myxoid liposarcoma and other myxoid soft tissue tumors is discussed,

Hyalinizing trabecular adenoma is an uncommon benign thyroid tumor that is recently described in the literature. This tumor is easily confused with medullary carcinoma on surgical specimens and with papillay carcinoma on cytologic specimens. Herein we report the cytologic characteristics of a case of histologically proven hyalinizing trabecular adenoma of the thyroid gland. Cytologically, the aspirate showed trabecular or individually dispersed polygonal cells with finely stippled chromatin pattern, nuclear grooves, and eosinophilic nuclear pseudoinclusions. No colloid materials were noted in the background.

Many researchers report that the measurement of urine calcium concentration during antenatal period is helpful in prediction of having preeclampsia,but some don`t. The purpose of this clinical study is to evaluate the relationship of low calcium level in urine and the develpoment of preeclampsia, and effects of other variables. 24hour urine were collected and measured for the concentration of calcium and creatinine from 769 pregnant women who visited our department of obstetrics at Young-Dong Severeance hospital, Yonsei university medical college for antenatal care from March 1, 1993 to May 31, 1996. One group of 41 women developed preeclampsia and the other didn`t. There were no diffrences in ages and gestational age at urine collection between two groups, but a group with preeclampsia had an increased mean arterial blood pressure. There were signiificant difference in calcium concentration in urine and ratios of concentration of calcium and creatinine from urine collected between gestational ages of 25 weeks and 32 weeks and also in those women younger than 25 years old and their first pregnancy. Our study suggests that the measure ment of calcium level and ratios of urine calcium concentration and creatinine concentration at gestational ages between 25 weeks and 32 weeks in women younger than 25 year old with their first pregnancy is quite helpful inpredicting the develpoment of preeclampsia.

Spontaneous coronary artery dissection(SCD) is a rare entity that is infrequently diasnosed antemortem. The majority of patients have presented with acute myocardial infaction or sudden death. the etiology, prognosis and treatment of this entity remain ill-defined. We report two cases of SCD which were diagnosed by coronary agniogram and intracoronary ultrasound.
