The RhD antigen is expressed only in human red blood cells (RBC).Its immunogenicity and clinical application are only next to ABO blood group system, and is widely used both for blood typing and prevention of hemolytic disease of the newborn. The traditional anti-Rh(D) is derived by fractionation of plasma from individuals who have been sensitized by pregnancy or transfusion, or have been deliberately immunized to produce anti-Rh(D). Because of the limited source of plasma, researchers began the study of monoclonal and recombinant antibody. Monoclonal and recombinant anti-Rh(D) antibodies may provide alternatives to the current plasma derived polyclonal IgG anti-Rh(D), but up to now,none of them have yet proved effective in humans for prevention of RhD immunity and hemolytic disease of the newborn.

Subungual exostosis is a solitary fibrus nodule on the inner border of the terminal phalanx of the great toe. Rarely, the terminal phalanges of other toes, particularly the little toe, or even the fingers are involved. The first appearance is a small pinkish growth projecting slightly beyond the inner free edge of the nail, which pushes upward and backward. A case of Subungual exostosis affecting 20 year old man, who has been suffering from bean sized nolule on subungual area of terminal phalanx of left 5th toe. The skin iesion developed 1 year ago, and increased size insidiously and tendemess on pressure or tight shoes was noted. Diagnosis was confirmed by histopathologic and radiologic studies, and treated witb complete excision of tumor mass.
