Pigmentary dermarcation lines are boundaries between more deeply pigmented skin and areas of lighter pigmentation. We report 4 cases of pigmentary demarcation lines of pregnancy associated with erythema which developed in the third trimester of pregnancy and were symmetrically located in the buttock and posteromedial portion of the lower extremities. After delivery, the erythema disappeared within 3-7 days, followed by slow resolution of the brownish pigmentation.

Retroperitoneum is often the site of occurrence of schwannoma, but reports on schwanoma of the adrenal gland is exceptional and only 4 cases have been documented in the literature. This report is to add one such case occurred in a 53 year-old male who had anorexia, nausea and indigestion for one month. Whole body bone scan and abdominal CT scan revealed a 10 cm sized solid mass at upper pole of the left kidney. Under the impression of renal cell carcinoma, an operation was performed. The tumor was well encapsulated and appeared not to involve the kidney. The cut surfaces were light yellow and seemed to be composed of several hard lobules with areas of mucoid, cystic and calcific changes. No adrenal gland was identified grossly. But microscopically, the tumor was found to be partly surrounded by a small portion of adrenal cortical tissue. Histologically the tumor was a typical schwannoma with Verocay bodies, although modified in some extents by mucoid degeneration, cystic change, hyaline change and focal calcification. It is worthwhile to remember that the retroperitoneal schwannoma commonly had a huge size, sometimes involving the adjacent structures.

Prurigo pigmentosa(PP) is a rare dermatosis with an unknown cause characterized by intensely pruritic papules that resolve with reticulate pigmentation. It is a disease entitity commonly reported in Japan but seemingly rare in other parts of the world. We report 5 cases that clinically and histopathologically fulfilled the characterisitics of PP and were treated with dapsone resulting in significant clinical improvement.

OBJECTIVE: To evaluate the intrauterine hypoxic effect in term small-for-date (SGA) neonates by comparing the umbilical venous erythropoietin (EPO) concentration between appropriately-grown (AGA) and SGA neonates at delivery and to determine the variables that correlate with the umbilical venous EPO concentration by multiple regression analysis. METHODS: 183 term singleton neonates (gestational weeks > OR =37) were enrolled and divided into 136 cases of AGA (10th-90th percentile of birth weight for the gestational age) and 47 cases of SGA (< 10th percentile of birth weight for the gestational age. At each delivery, blood gas values, concentration of EPO by radioimmunoassay and the number of nucleated erythrocytes (NRBC) per 100 white blood cells in smear of umbilical venous blood were obtained. The placentas were examined microscopically for presence of pathological infarct. Statistical analysis was done by Mann-Whitney U test, x2 test, and univariate and multiple regression analysis using SPSS statistical package (version 10). RESULTS: The median umbilical venous EPO concentration, fetal hemoglobin level were significantly higher in SGA neonates than those in AGA neonates. There was no difference in number of NRBC between AGA and SGA neonates. Multiple regression analysis model with level of NRBC, presence of placental infarct and SGA provided prediction of EPO level in umbilical venous blood at delivery (regression equation: EPO=-103.94+4.75NRBC+68.07placental infarct+36.40SGA F=15.57. r2=0.47). CONCLUSION: Term SGA neonates was considered to have compensatory, not pathological intrauterine hypoxic effect by showing increased level of EPO and normal level of NRBC in umbilical venous blood at delivery, compared with thoses of AGA. In the suspected cases of SGA antenatally, measurement of NRBC level and placental pathologic examination for infarct can be informative for estimating the extent and duration of intrauterine hypoxia.
