Soft Tissue Chondroma—Result of Surgery in a Local Hospital and Review of the Literature: 軟組織軟骨瘤: 地區醫院之手術治療成效及文獻回顧

Background/PurposeThis was a retrospective case series that aimed to study the clinical features and results of surgery for soft tissue chondroma, which is a benign extraskeletal cartilage tumour.MethodsTen patients with a histological diagnosis of soft tissue chondroma were recruited between 2001 and 2012. Tumours involved the hand and wrist (n = 4), foot (n = 3), popliteal fossa (n = 2), and deltoid (n = 1).ResultsThe most common complaints were progressive enlargement of the size of the mass (50%) and pain (50%). Radiographs showed calcified soft tissue mass in 90% of cases. Marginal excision was performed. The mean follow-up duration was 27.6 months. There was one suspected recurrence case with a mass over the index finger. Surgical re-excision was performed and the second histological diagnosis was bizarre parosteal osteochondromatous proliferation. At final follow-up, nine out of ten cases were symptom free. One patient had residual finger joint stiffness and deformity.ConclusionThe results of marginal excisions for soft tissue chondroma is satisfactory with low complication and recurrence rates.

中 文 摘 要本文是一個回顧性的系列病例報告,目的為探討良性軟組織軟骨瘤的臨床表徵和手術的治療成效。我們收集了10宗於2001至2012年間在本醫院處理的軟組織軟骨瘤病例。軟組織軟骨瘤影響的位置包括手和手腕(4病例),足部(3病例),膕窩(2病例) 及三角肌(1病例)。最常見的病徵為腫瘤變大(50%)及疼痛(50%)。90% 的病例於X線片中顯示鈣化軟組織腫塊。所有病人接受了邊緣切除手術,病理診斷為軟組織軟骨瘤。平均隨訪時期為27.6個月。一位病人懷疑手指局部復發並再次接受切除手術,其病理診斷為奇異的骨膜旁骨軟骨性增生。在末次隨訪,該病人有手指關節僵硬和畸形的情況,其餘的人皆沒有徵狀。總結:邊緣切除軟組織軟骨瘤手術的結果是令人滿意的,並發症和復發率不高。
