An Unusual Klebsiella Septic Bursitis Mimicking a Soft Tissue Tumor

Abstract

Because of its subcutaneous location prepatellar bursitis is frequently complicated by an infection. Gram-positive organisms, primarily Staphylococcus aureus account for the majority of cases of septic bursitis. Local cutaneous trauma can lead to direct inoculation of the bursa with normal skin flora in patients with occupations, such as mechanics, carpenters and farmers. A 71-year-old male was admitted to our department with a history of pain and swelling of his right knee over a 20 year period. Physical examination revealed a swollen, suppurative mass with ulceration of the skin and local erythema which mimicked a soft tissue tumor at first sight. Magnetic resonance imaging of the knee revealed a 13*12*10cm well-circumscribed, septated, capsulated, fluid-filled prepatellar bursa without evidence of tendinous or muscular invasion. The mass was excised en bloc, including the bursa and the overlying skin. The defect was closed with a split thickness skin graft. The patient had 100 degrees flexion and full extension after 45 days postoperatively, and he continued to work as a farmer.

An Unusual Klebsiella Septic Bursitis Mimicking a Soft Tissue Tumor

Öz

ilt altı yerleşiminden dolayı prepatellar bursitlerde enfeksiyon görülmesi sık olur. Gram pozitif mikroorganizmalar, özellikle stafilokokkus aureus en sık etkendir. Tamirciler, halıcılar ve çiftçiler gibi travmaya çok maruz kalan meslek gruplarında direk olarak etken cilt florasından bursaya ulaşabilir. 71 yaşında erkek hasta 20 yılı aşan ağrı ve şişlik nedeni ile kliniğimize başvurdu. Diz üstündeki eritemli,ülseratif ve akıntılı kitle ilk bakışta yumuşak doku tümörüne benziyordu. Manyetik Rezonans incelemede 13*12*10cm boyutlarında iyi sınırlı,septalı,kapsüle sıvı dolu prepatellar bursanın tendinöz veya kas invazyonu yoktu. Kitle üzerindeki cilt ile beraber çıkartıldı ve defekt kısmi kalınlıkta cilt grefti ile kapatıldı. Hastanın 45 gün sonraki kontrolünde 100 derece fleksiyonu ve tam ekstansiyonu vardı ve eski işini yapabiliyordu
