Desmoplastic small round cell tumor (DSRCT) is a rare neoplasm of young adults and it is characterized by polyphenotypic differentiation. We experienced a case of abdominal DSRCT that occurred in a 19-year-old female who presented with painful swelling of her right forearm. The tumor was cytokeratin-negative and it exhibited some tumor cells with intranuclear inclusions. Molecular demonstration of EWS-WT1 fusion transcripts is particularly useful to confirm the diagnosis of DSRCT without epithelial differentiation. We report here on a case of cytokeratin-negative DSRCT that showed an unusual feature of intranuclear inclusions.

Correct discrimination of the first and the second twin is important. Case: (1) The first fetus, whose amnionic cavity was closest to the cervix at 19 weeks, even though its body was higher than the second fetus, was found to be closer to the cervix by 23 gestational weeks than its twin. (2) The result of the chromosomal study of dichorionic twins at 17 gestational weeks was male with 9 inversion of the presumed first, and female with trisomy 21 of the presumed second. AT 19 gestational weeks, the sex and order of the two were found to be reversed at sonography for selective termination. In diamnionic twins, the fetus in the amnionic sac closest to the cervix is nominated as the first.

Ectopic paragonimiasis has been diagnosed in many organs such as the mesentery, ovary, pleura, central nervous system, subcutis and very rarely in the liver. However, simultaneous involvement of the colon and liver, which mimics colonic cancer with liver metastasis, is quite unusual, and to our knowledge has never been reported. Our case is a 63 year old woman who visited our hospital because of upper abdominal pain. Radiologically, space occupying lesions were detected in the transverse colon, mesocolon and left hepatic lobe. After the radical presection, they were proved to be an ectopic paragonimiasis forming multiple cavitary parasitic granulomas with Charcot-Leyden crystals and degenerating eggs.

A 33-year-old-woman with twin pregnancy underwent genetic amniocentesis in our hospital at 16 weeks of gestation. Fetal chromosomal analysis showed 46,XY,inv(9) and 47,XX,+21. The affected twin was terminated by ultrasonographically guided intracardiac injection of 3 ml potassium chloride solution at 19 weeks of gestation. A healthy 2570 g male infant was born by cesarean section with Apgar scores of 8 and 9 at one and five minutes, respectively.

The spindle and epithelioid cell nevus, is known also as Spitz's nevus or benign juvenile melanoma. The histologic picture of the lesion often closely resembles that of a malignant melanoma, but spindle and epithelioid cell nevus hehaves benignly. Criteria for accurate histological diagnosis of this nevus now exist. However, a difficult lesion occasionally brings one to the worrisome situation even now. We experienced four cases (three children and one adult) of spindle and epithelioid cell neveus with nodular or macular skin lesions. In children (7/F, 9/F, 4/M), all of the lesion show a solitary pinkish red or light brown nodular firm masses, 0.7 cm to 1.0 cm in greatest dimension, which are located at the left posterior thigh, posterior neck and right anterior neck region, respectively. In adult (36/F), the lesion shows a light brown, erythematous macule, 0.8 cm in greatest diameter, in the skin of the back. Microscopically, both spindle and epithelioid cells are found in all the four cases, but epithelioid cells predominate in children and spindle cells predominate in adult.

PURPOSE: Laparoscopic approaches to the anterior abdominal wall are difficult because of the inherent limitations of laparoscopic surgery. METHODS: A 25-year-old young female visited to our hospital with an incidentally-found palpable abdominal mass. Computed tomography revealed a 7-cm round enhancing mass arising from the left posterior rectus sheath. The patient underwent laparoscopic excision of the inner mass arising from the anterior abdominal wall. RESULTS: The operation lasted for 45 minutes and there was no measurable bleeding during the procedure. Pathological assessment revealed that the tumor was a DTF 7.0 cm in size. The patient was discharged on the second postoperative day in good condition, and is currently being followed on a routine basis for surveillance without adjuvant therapy. CONCLUSION: Laparoscopic approach for the anterior abdominal wall tumor could be feasible in select patients. This minimally-invasive approach helps to ensure good cosmetic outcomes and quality of life.

PURPOSE: We evaluated the surgical outcomes and complications of new pediatric intraocular lens in congenital cataract. METHODS: A retrospective study was carried out on 29 eyes of 22 patients diagnosed with congenital cataract that underwent optic capture following lens emulsification. New pediatric intraocular lens (LJC 575A, Lucid Korea, Seoul, Korea) implantation into the bag was performed with posterior capsulorrhexis and anterior vitrectomy. RESULTS: After follow-up of 17.79+/-7.08 months, 15 eyes showed a visual acuity of 0.5 or above, and 10 (71.4%) of the 14 eyes showed a visual acuity of 20/470 or above. As for complications, posterior synechia developed in 8 eyes, exudative membrane was found in 3 eyes, iris capture by IOL haptic was found in 1 eye, and slight opacification of posterior capsule was identified in 1 eye. CONCLUSIONS: Use of new 8 mm pediatric intraocular lens in congenital cataract may be considered selectively.
