FOREIGN-BODY HISTIOCYTOSIS REACTION AFTER HIP-REPLACEMENT WITH CONCOMITANT METASTATIC ADENOCARCINOMA IN THE SAME LYMPH-NODE

Infiltration of regional lymph nodes by macrophages has been shown aft er total joint arthroplasty. These pelvic lymph nodes were obtained mo st often from patients during staging procedures for carcinoma and may be a diagnostic pitfall in the frozen section diagnosis of nodal meta stasis. We report an unusual case of association in the same lymph nod e between histiocytosis and prostatic carcinoma metastasis. Histiocyto sis was caused by wear debris from two different prostheses. Inductive ly coupled plasma mass spectrometry verified this diagnosis. Copyright (C) 1998 by W.B. Saunders Company.
