Abstract PDF: Background
：Regional lymphadenitis is a common complication after BCG vaccination and has various clinical course. Various treatment, including medical, surgical, and combined are used to treat BCG lymphadenitis, but results are controversial. This study was performed to provide guidelines for surgical approach to BCG lymphadenitis. Materials and Methods：37 patients with BCG lymphadenitis at Yeungnam University Hospital between March 2004 and August 2007 were retrospectively reviewed. Suppurative BCG lymphadenitis were treated by surgical excision or incision and curettage. Non-suppurative BCG lymphadenitis were observed without any treatment and surgical treatment was applied when it became suppurative.
Results
：The mean age was 7.5 months(range 2-47 months) and most prevalent site of lesion was the ipsilateral axilla. Among 37 cases, 20 cases were already suppurative when diagnosed and 2 cases of 17 non-suppurative BCG lymphadenitis showed spontaneous resolution without any treatment. Surgery was performed successfully on 35 suppurative BCG lymphadenitis and postoperative complication was trivial.
Conclusion
：Suppurative BCG lymphadenitis were successfully treated with excision or incision and curettage without any serious complication. So non-suppurative BCG lymphadenitis can be observed expecting spontaneous resolution.

Angiomatoid fibrous histiocytoma is a rare soft tissue tumor that generally affects children and young adults. We report a case of angiomatoid fibrous histiocytoma in an 11-year-old boy who complained of a back mass for 3 years. Surgical excision was performed. The excised specimen showed a 4.0 x 3.6 x 3.0 cm, well circumscribed, grayish white tumor, with multicystic changes. Histological examination showed proliferation of spindle or round shaped tumor cells. There was a dense fibrous pseudocapsule with prominent chronic inflammatory cell infiltrates.

Abstract PDF: Hirschsprung's disease is one of the most common causes of intestinal obstruction in neonates and infants. The underlying pathology of this disease is the absence of the ganglion cells in both the myenteric (Auerbach's) plexus and the submucosal (Meissner's) plexus. Since Hirschsprung's report in 1886, there have been thousands of papers on Hirschsprung's disease but the cause of the absence of the ganglion cells has not been identified. Hirschsprung's disease can be successfully treated with the Swenson, the Duhamel, and the Soave operations even though the pathogenesis is unknown. With the recent progress of molecular biology and genetics, a more detailed approach to the pathogenesis of Hirschsprung's disease can be undertaken. In addition, there have been recent developments in the surgical approach. In this review, recent advances in surgery for Hirschsprung's disease are presented.
