Sánchez M.D.The American Journal of Dermatopathology: February 1990 Extraordinary Case Reports: PDF Only Buy Abstract A case of follicular lymphomatoid papulosis was studied by light- and electron-microscopic methods. The nature of atypical cells was analyzed with monoclonal antibodies. This case proved to be mainly a type B lymphomatoid papulosis with a predominance of T-helper markers in atypical lymphoid cells. All previously reported cases of this rare variant corresponded to type A lymphomatoid papulosis. Therefore we believe this to be the first case report of type B follicular lymphomatoid papulosis. © Lippincott-Raven Publishers.
