Abstract:Purpose: Particulate debris created by accelerated polyethylene wear in totaly replaced hips causes adverse local reactions. We report an extreme form of such a reaction in a patient who developed progressive thigh pain, weakness and numbness after total arthroplasty of his left hip. Methods: An abdominopelvic computed tomogram showed a large intrepelvic cystic mass interpreted as a malignant tumor. Dark greyish-green fluid was aspirated from the cyst and cytopathologic examination showed necrotic debris without malignant cells. Biopsy revealed necrosis and abundant foreign body granulation tissue with polarizable debris. Results: During surgical removal of the cyst a defect of the inner acetabular wall was noted. After successful revision arthroplasty with allograft bone the clinical symptoms improved. Conclusion: A foreign-body reaction to wear debris may produce an intrapelvic mass and corresponding symptoms. Cytologic and histologic examination of the mass or fluid may aid in interpreting the clinical picture and imaging studies.

Title:Inflammatory pseudotumor simulating malignancy: a rare complication after total hip arthroplasty
Abstract:Namen: Tujkov drobir, ki nastaja po vstavitvi popolne kolčne endoproteze, povzroča neželene lokalne odgovore gostitelja. Prispevek povzroča o izraziti obliki takšnega odgovora bolnika, pri katerem je po popolni artroplastiki levega kolka prišlo do naraščajoče stegenske bolečine, izgube mišične moči in odrevenelosti. Metode: Računalniška tomografija spodnjega dela trebuha in medenice bolnika je pokazala veliko cistično tvorbo. Ocenili smo jo kot maligni tumor. Z aspiracijsko biopsijo ciste smo dobili sivo-zeleno tekočino, s citološko preiskavo je bil ugotovljen nekrotični drobir brez malignih celic. Z biopsijo smo potrdili nekroze in obilno granulacijsko tkivo tujkovega tipa z drobirjem, ki je pod polarizacijskim mikroskopom značilno lomil svetlobo. Rezultati: Med kirurško odstranitvijo cistične tvorbe smo opazili defekt kostnine notranje stene kolčnice. Po uspešni revizijski artroplastiki in uporabi homolognih kostnih presadkov so bolnikove težave izzvenele. Zaključki: Vnetna reakcija tujkovega tipa na obrabne delce endoproteze lahko povzroči rast medeničnega tumorja in posledične simptome. Citološka in histološka preiskava tumorja ali njegove tekoče vsebine lahko pomaga razložiti klinično sliko in izvide slikovnih diagnostičnih preiskav.
