We describe a 23-year-old man showing typically clinical and histological features of targetoid hemosiderotic hemangioma. About 35 cases of this newly-described entity have been reported since the first description by Santa Cruz and Aronherg in 1988. It is important to distinguish these tumors from patch stage Kaposi's sarcoma, retiform hemangioendothelioma and progressive lymphangioma.

Acute colonic pseudoobstruction was first reported in 1948 by Sir H. Ogilvie. It is characterized by an acute, abrupt right-sided colonic distention in the absence of physical reasons for obstruction. If untreated, it may progress to cecal perforation, peritonitis, and death. Although primary cases have been reported, 87 percent of cases were secondary results of medical or surgical conditions. The most common medical conditions were infections, cardiac disease, and neurologic problems. In surgical conditions, cesarean section has been reported as the most common cause of Ogilvie's syndrome. In 1995, the first case of Ogilvie's syndrome complicated after a cosmetic surgical procedure(abdominoplasty) was reported by Bradley et al. We report a case of Ogilvie's syndrome complicated after breast reconstruction with TRAM flap that developed in the postoperative third day in 35-year old woman. The complications are primarily related to decreased flap perfusion. No reference of intestinal pseudoobstruction was found in the literature conducted in regard to complications of TRAM flap breast reconstruction.

Sparganosis is an infection caused by the migrating larvae of the cestode genus Spirometra. The most common clinical presentation of a sparganosis is a slow-growing, sometimes migratory, sub-cutaneous mass. In this report, a case of eosinophilic panniculitis by sparganum in a Korean woman is presented. The diagnosis was confirmed from the histopathologic findings, the micro-ELISA tests and a living sparganum derived from the patient while excising the new lesion

Neonatal lupus erythematous is a rare syndrome, which is characterized by a transient lupus dermatitis, hematologic abnormalities and isolated congenital heart block. We detected the atrioventricular dissociation, bradycardia and pericardial effusion by fetal echocardiography in a female fetus at 25th weeks of gestational age. The baby was born in the 38th week of pregnancy by Cesarean section with 1790 gram of body weight. In spite of atrioventricular dissociation with bradycardia and pericardial effusion, cardiac pacemaker was not needed during neonatal period because she was doing well, no evidence of congestive heart failure and around 80 beat per minute of heart rate. The serologic markers for diagnosis of neonatal lupus are the autoantibodies specific to SS-A/Ro and/or SS-B/La. These antibodies are produced by the mother and passed to the fetus through the placenta. Autoantibodies of cytoplasmic SS-A antigens or SS-B antigen were found in the blood of this patient and her mother. We report a case of neonatal lupus syndrome with congenital atrioventricular dissociation with Rt. Bundle branch block and hematologic abnormality.

The Mainz classification for renal cell tumors was introduced in 1986 and it's utility has been reported in several histogenetic and genetic studies of renal cell tumors. We present a study of 127 cases of renal cell tumors with clinicopathologic correlation, DNA content analysis, and histogenesis studied by histochemical and immunohistochemical staining. The 127 renal cell tumors classified by the Mainz classification were 87 clear cell, 17 chromophilic, 13 chromophobe and 3 sarcomatoid renal cell carcinomas, 5 oncocytomas and 2 adenomas. These subtypes showed significant correlation not with age, sex, Robson's stage, DNA ploidy or tumor recurrence but with nuclear grade (p=0.001) and tumor size (p=0.001). Hall's colloidal iron (p=0.002) and carbonic anhydrase II (p=0.013) stains, representing the origin of distal nephron especially of collecting duct, were significantly correlated with specific subtypes of renal cell tumors, especially chromophobe cell renal carcinoma. This study demonstrates that the Mainz classification suggests several morphologically different subtypes and variants of renal cell tumors and that some of them may have originated from the distal nephron, particularly from the collecting duct.

PURPOSE: To investigate the clinical courses after panretinal photocoagulation (PRP) in diabetic retinopathy patients. METHODS: We performed a retrospective study on 138 patients, 229 eyes, who have been treated with the PRP more than a year ago from June 1996 to September 2000. RESULTS: After PRP, 30% of the patients showed decreased visual acuity. The degree of decline in visual acuity was the biggest in the patients who visited 2 weeks after the treatment (p=0.005). Thirty one percent of patients showed complete regression of neovascularization and 25% showed partial regression. Sixty seven percent (38 eyes) of the patients with no previous diabetic control showed visual loss after the treatment. There were also visual losses in 16% (15 eyes) of patients with oral hypoglycemic agents and 33% (27 eyes) with insulin therapy (Spearman correlation, r=0.221, p=0.001). In the case of low visual acuity group (or=20/40). On the other hand, 62% of the patients maintained good visual acuity and only 12% showed low visual acuity in good visual acuity group. Within one year after PRP, 44 eyes (19%) of patients developed macular edema, 51 eye (22%) of patients showed vitreous hemorrhage and 3% developed tractional retinal detachment. Ten (20%) out of 51 eyes which showed vitreous hemorrhage had the operation. CONCLUSIONS: Better visual acuity before PRP and strict diabetic control affect the good prognosis after panretinal photocoagulation.

Purpose: To report a case of retrobulbar optic neuritis after COVID-19 infection.Case summary: A 20-year-old Korean man, without any previous relevant medical history, presented with sudden blurred vision in the left eye that began 6 days after a COVID-19 infection. At his initial visit, the best-corrected visual acuity in the left eye was counting fingers at 30 cm. The pupil showed a grade 2 relative afferent pupillary defect. The fundus exam was normal in both eyes. In the visual evoked potential (VEP) exam, the P100 amplitude of the left eye was decreased and delayed. Orbit magnetic resonance imaging showed asymmetric enlargement and mild enhancement in the left optic nerve. No other lesions were observed around the optic nerve. Steroid pulse therapy was started after a diagnosis of retrobulbar optic neuritis. After 1 month, the patient’s visual acuity had improved to 1.0 in the left eye. The relative afferent pupillary defect and visual field defect disappeared. On VEP, the P100 amplitude recovered, and the delay disappeared. Conclusions Retrobulbar optic neuritis is a possible neuro-ophthalmological complication of COVID-19 infection. In such cases, high-dose steroid pulse therapy may be helpful, as in the treatment of other forms of optic neuritis.
