序論:

挺側関節骨軟骨腫はあまり一般的ではありません。我々は3例に対して単純限界切除を行った。

INTRODUCTION: Para-articular osteochondromas are not very common. We performed simple marginal excision for three cases.

症例紹介:

膝蓋骨下脂肪パッドの関節周囲骨軟骨腫を3例経験した。症例はすべて男性で平均年齢は43歳であった。症状は膝前部痛と酷似しており、腫脹の増大と可動域の低下がみられた。単純縁切除術を行ったところ、症状は改善し、術後平均51ヶ月の間に再発や悪性転化は認められなかった。

PRESENTATION OF CASE: We encountered three cases of para-articular osteochondroma of the infrapatellar fat pad. All patients were men, with an average age of 43 years. The symptoms were very similar to those of anterior knee pain, which were increasing swelling and reduction of the range of motion. After simple marginal excision was performed, the symptoms improved and no recurrences or malignant transformation occurred during the mean postoperative period of 51 months.

DISCUSSION:

47例の関節外骨軟骨腫が報告されており、切除が標準治療となっている。局所再発は1例のみで、悪性転化は一度も報告されていない。しかし、一部の報告では切除法の指定がなく、単に"切除"と記載されていました。したがって、当院では3例とも単純な限界切除法を用いた。

DISCUSSION: Forty-seven cases of para-articular osteochondroma have been reported, and excision is the standard treatment. Local recurrence has been reported in only one case, and malignant transformation has never been reported. However, in some reports there was no specification of the excision method, which was simply referred to as "excision." Thus, we used a simple marginal excision for all three of our cases.

結論:

単純辺縁切除術で効果的に治療できた膝蓋骨下脂肪パッド関節外骨軟骨腫の3例を報告する。

CONCLUSION: We report three cases of para-articular osteochondroma of the infrapatellar fat pad that were effectively treated using simple marginal excision.
