Nodular fasciitis is a benign, self-limited myofibroblastic proliferative lesion of unclear aetiology. It is often misdiagnosed as a malignant tumour due to its rapid growth, high cellularity, and increased mitotic activity.
We present a case of nodular fasciitis occurring in the medial canthus of a 64-year-old, otherwise healthy, woman. The patient complained of rapidly enlarging asymptomatic subcutaneous nodule over a period of 6 months. The tumour was firm, smooth, and indolent with limited mobility. Fine-needle aspiration was inconclusive, and the CT scan showed a well-defined nodular lesion in the soft tissue without bone destruction. A local excision was performed, and the histopathological findings were consistent with nodular fasciitis.
Although rare, nodular fasciitis is the most common pseudosarcoma of soft tissues. Local excision is recommended; however, the tumour often regresses spontaneously, and recurrence is exceedingly rare.
Awareness of nodular fasciitis and its benign nature is essential to avoid misdiagnosis and subsequent inappropriate aggressive treatment of the patient.
结节性筋膜炎是一种病因不明的良性、自限性肌成纤维细胞增生性病变。由于其生长迅速、细胞丰富且有丝分裂活性增加,常被误诊为恶性肿瘤。
我们报告一例发生在一名64岁健康女性内眦部的结节性筋膜炎病例。患者主诉在6个月内出现一个迅速增大的无症状皮下结节。肿瘤质地坚硬、表面光滑,生长缓慢,活动度有限。细针穿刺活检结果不明确,CT扫描显示软组织内有一个边界清晰的结节性病变,无骨质破坏。进行了局部切除,组织病理学检查结果与结节性筋膜炎一致。
结节性筋膜炎虽然罕见,但却是最常见的软组织假肉瘤。建议进行局部切除;然而,肿瘤通常会自发消退,复发极为罕见。
认识结节性筋膜炎及其良性性质对于避免误诊和随后对患者进行不适当的积极治疗至关重要。
