Adverse Local Tissue Reaction and Late-Onset Eosinophilic Gastroenteritis After Primary Total Hip Arthroplasty: A Case Report.

CASE: A 67-year-old woman suffered from chronic diarrhea at 10 years after right total hip arthroplasty. She also had a pseudotumor caused by an adverse local tissue reaction (ALTR) in her right pelvis. We performed revision arthroplasty, in part because we suspected the diarrhea may have been associated with the intrapelvic pseudotumor. She was later diagnosed with eosinophilic gastroenteritis (EGE).

CONCLUSION: Although these two diseases were thought be be related through a similar immune reaction, our patient's clinical course suggests that the ALTR and EGE were independent events.
