Congenital self-healing reticulohistiocytosis (CSHRH) typically presents at birth or in the first few weeks of life as a widespread eruption of cutaneous red-brown papulonodules that resolve spontaneously without involvement of other organs. While multiple lesions are common, a solitary lesion is rare. We describe a solitary type of CSHRH in a full-term, male neonate. He had an erythematous papule with a yellowish crust on the left heel without any systemic symptoms. Four weeks later, the skin lesion had disappeared spontaneously.

The clinical and pathological features of trichoadenoma are presented. Trichoadenoma is very rare, and as far as we know, no report on the trichoadenoma has been published in korea literature. We experienced a case of trichoadenoma occured in a 29 year-old male, who had a 0.9x0.7x0.4cm sized and slowly growing mass in the right buttock. The histopathological findings and histogenesis of trichoadenoma were discussed and a brief review of the literature was made.

Sebaceous epithelioma is a relatively rare tumor, mostly occuring in the face or scalp. The histogenesis and clinical and pathological features of sebaceous epithelioma have not been clearly defined, and a few other diagnostic terms have been used so far instead of sebaceous epithelioma. Two cases of sebacous epitheliomas were presented. No recurrence or metastasis was observed in our cases, so sebaceous epithelioma is considered to be a benign tumor. A brief review of the literature, concerned about the biological behavior, histogenesis and pathological findings of the sebaceous epithelioma, was made.

Peritoneal mesothelioma is a rare disease which arises from the mesothelial lining cells in the peritoneum and spreads to the peritoneal wall, omentum and other abdomina1 organs. Aabestos is one etiologic factor and the other factors are genetic cause, radiation, exposure to toxic materials and recurrent yeritonitis. We experienced a case of multiple small nodular peritoneal mesothelioma after exposure to asbestos for over 20 years. He was a sailor and had worked in the engine department of the ship, in which he wrapped up the pipe of engine in asbestos. This person came to our hospital because of inconvenience due to a distended abdomen. Tumor markers were all within normal limits and there was no evidence of tuberculosis in the abdomen and chest. The CT findings of the abdomen were as follows: There was abundant ascites in the abdominal cavity and multiple small nodules on the parietal peritoneum and especially on the lower abdomen. The omentum thickened diffusely. It was difficult to distinguish from peritoneal mesothelioma and peritoneal carcinomatosis or intestinal tuberculosis. The laparoscopic findings were as follows: There were multiple small nodules on the parietal peritoneum and omentum. The small nodules were a gray white color and uneven compared to tuberculous peritonitis. Therefore, we observed the malignant mesothelial cells by means of the light microscope and electron microscope and concluded that this case was peritoneal mesothelioma.

PURPOSE: It is known that single umbilical artery is frequently associated with gastrointestinal or urogenital anomaly, however, routine renal sonography has been debated in healthy neonate with isolated single umbilical artery. This study is designed to determine the usefulness of routine renal sonography in apparently healthy infants with an isolated single umbilical artery. METHODS: Thirty healthy neonates with a single umbilical artery without a major anomaly from January 1995 to July 2002 were enrolled. The authors investigated the clinical background of babies and their mothers after renal sonography after 72 hours of age. When the abnormalities were found at the first renal sonography, the severity of hydronephrosis and degree of obstruction and renal function were analyzed by follow up renal sonography, voiding cystourethrography(VCUG) and technetium-99m-dimercaptosuccinic acid(DMSA) scan or technetium-99m-mercaptoacetyl-triglycerine (MAG3) scan. RESULTS: Among the 30 healthy patients with isolated single umbilical artery, five patients(16.7%) showed abnormalities on first renal sonography with one major(3.3%) and four(13.4%) minor renal anomaly(minimal or mild hydroneohrosis). One major renal anomaly(severe hydronephrosis) showed severe decreased renal function on MAG3 scan without reflux, and the other four minor regressed spontaneously on follow up study. CONCLUSION: The value of routine early renal sonograpy for detecting renal anomaly in healthy infants with an isolated single umbilical artery remained unclear because most of the anomalies would regress spontaneously in the follow up study.

PURPOSE: Ultrasonography is being widely used as a standard test in obstetric care, studies on congenital hydronephrosis. Focusing on specific prenatal history and frequently associated anomalies in newborn infants with hydronephrosis, this investigation was intended to suggest particulars that need to be considered in making an accurate diagnosis of fetal hydronephrosis. METHODS: From May 2000 to May 2005, retrospective study was conducted on 67 patients (93 kidney) who had been diagnosed by renal ultrasonography during neonatal periods. Hydronephrosis was defined as having a pelvic diameter more than 5 mm, and was classified into three groups according to their severity;mild (grade I, II), moderate (grade III) and severe (grade IV). RESULTS: This study included 67 cases with 54 male and 13 female infants. There were 35 cases with a specific prenatal history in 22 infants such as oligohydramnios, intrauterine growth retardation, preeclampsia and others. 33 cases in 23 infants had associated anomalies such as urogenital anomalies, cardiac anomalies. Of these 67 infants (97 kidneys), 49.5% was mild, 30.1% moderate, 20.4% severe hydronephrosis. Infants with moderate hydronephrosis had more specific prenatal history and associated anomaly than the mild hydronephrosis did (68.2% vs 31.8%, P<0.001 73.7% vs 26.3%, P<0.001). CONCLUSION: Particular attention should be paid for cases with congenital hydronephrosis with a specific prenatal history to find out any associated congenital anomalies (such as urogenital or cardiac anomalies). This will enable clinicians to establish a more appropriate treatment and postnatal care.

PURPOSE: To evaluate the relationship between focal aggravation of the macular edema on retinal thickness change analysis (RTCA) of optical coherence tomography (OCT) and fluorescein angiographic findings in patients after an intravitreal triamcinolone injection (IVTA). METHODS: From May 2004 to April 2005, RTCA in a fast macular thickness map (FMTM) of OCT was performed before and 4 weeks after IVTA in patients who had macular edemas caused by diabetic retinopathy and retinal vein occlusion. Patients underwent IVTA, and focal aggravation of the edema was detected. After overlapping the OCT findings onto angiographic pictures, the relationship between the focal aggravation on OCT and the leaking point on angiography was investigated. RESULT: In the patient group, focal aggravation was found in 5 of 27 eyes (18.5%); in the control group, only 2 of 30 eyes (6.7%) showed focal aggravation. As compared with angiographic pictures, 4 eyes with focal aggravation showed no relation to the leakage on angiography. CONCLUSIONS: Focal aggravation of macular edemas after IVTA on RTCA are not related to the leakage on angiography and could be an error from several artifacts.
