title: Foreign body histiocytosis reaction after hip replacement with concomitant metastatic adenocarcinoma in the same lymph node.
abstract: Infiltration of regional lymph nodes by macrophages has been shown after total joint arthroplasty. These pelvic lymph nodes were obtained most often from patients during staging procedures for carcinoma and may be a diagnostic pitfall in the frozen section diagnosis of nodal metastasis. We report an unusual case of association in the same lymph node between histiocytosis and prostatic carcinoma metastasis. Histiocytosis was caused by wear debris from two different prostheses. Inductively coupled plasma mass spectrometry verified this diagnosis.
