Background and importance

Asymptomatic myelomeningoceles are usually more of cosmetic deformities and left without evaluation and untreated, amongst low socio-economic strata. Such midline swellings, if left neglected may become the seat for malignancies, usually of squamous cell origin.

Clinical presentation

The authors report a case of an 18-year-old male patient who developed leiomyosarcoma within chronically neglected cervical myelomeningocele.

Conclusion

A non-healing ulcer of any aetiology is a bed for carcinogenesis. Neglected myelomeningoceles, for any reason, may convert a benign entity to a malignant pathology. To our best knowledge, this is the first case of a leiomyosarcoma arising de novo from myelomeningocele.

颈部脊髓脊膜膨出中的平滑肌肉瘤：一个被忽视的病例中的罕见并发症

背景和重要性

无症状的脊髓脊膜膨出通常更多是美容畸形，并且在社会经济阶层较低的情况下未经评估和治疗。这种中线肿胀，如果被忽视，可能会成为恶性肿瘤的发生地，通常是鳞状细胞起源的。

临床表现

作者报告了一例 18 岁男性患者，他在长期被忽视的颈部脊髓脊膜膨出中发展出平滑肌肉瘤。

结论

任何病因的不愈合溃疡都是致癌的温床。无论出于何种原因，被忽视的脊髓脊膜膨出都可能将良性实体转变为恶性病变。据我们所知，这是第一例由脊髓脊膜膨出新发的平滑肌肉瘤病例。
