 Abstract
 PDF
- Traditionally, pathologists have used human biological material primarily for diagnostic purposes. More recently, advances in biomedical technology and changes in the research environment have placed new demands on pathologists and their handling of human materials. Moreover, these technological advances have required pathologists to be not only experts in diagnosis, but also managers of biobanks storing human biological material. Consequently, pathologists might now be confronted with unanticipated legal and ethical questions. We investigated seven examples of South Korean legislation concerning human biological material, including "The Bioethics and Safety Act" (2005), and we considered possible conflicts of interest between donors and researchers. We also reviewed international bioethical guidelines and legal precedents from several countries with special regard to pathologic glass slides, paraffin blocks, remaining specimens and other guidelines.
We conclude that a better understanding of the legal and ethical questions concerning human biological material leads pathologists to safer and more conscientious management of these samples.

- BACKGROUND
Langerhans cell histiocytosis (LCH) is a well-known neoplastic disorder of Langerhans cells which has characteristic findings, however, LCH has not been adequately studied in Korea.
METHODS
We analyzed the clinicopathologic features of 20 patients with LCH who were diagnosed between 1997 and 2006 at the Korea University Guro and Anam Hospitals.
RESULTS
The M:F ratio was 3:1 and the age ranged from 2-60 years (mean, 23.8 years [4 in 1st decade, 6 in 2nd decade, 2 in 3rd decade, 5 in 4th decade and 3> or =40 years of age).
The cases were classified as unifocal unisystemic in 13 patients, multifocal unisystemic in 4 patients, and multifocal multisystemic in 3 patients. The bone was the most commonly involved organ (14), followed by lymph node (5), lung (2), skin (2) and ureter (1). The Langerhans cells were immunohistochemically stained with Langerin, CD1a, S-100 protein, and CD68. Langerin and CD1a were specific for Langerhans cells.
CONCLUSIONS
The distribution of the involved organs in patients with LCH was similar to the distribution in Western countries, but lymph node involvement was more frequent, whereas lung involvement was less common. Langerin is considered to be a specific marker for Langerhans cells.
