RESUMEN
The ligamentum nuchae is a midline structure extending from the occiput to the spinous process of the 7th cervical vertebra. Radio-opaque formations in the soft tissues behind the processes of the cervical spine has been known to radiologists since Barsony's description in 1929. It may actually be a normal sesamoid, or it may have developed as a result of previous trauma. But this remains hypothetical in that histological endochondral ossification sequence has not yet been demonstrated. These are generally asymptomatic and of clinical significance only in so far as they may be confused with fracture or tumors. Two patients who had clinical symptoms with or without previous trauma visited and they were relieved of their clinical symptoms by surgical excision. Then, we report on two unusual cases which were symptomatic.

Glomangiosarcoma is a histopathologically defined extremely rare malignant tumor that accompanies a glomus tumor usually, but its has benign clinical course characteristically. It shares common ultrastructural and immunohistochemical features with glomus tumor, and transformed possibly from glomus tumor". Glomangiosarcoma shows more sarcomatous appearance histologically than glomus tumor, however with no malignant behavior(i.e. recurrence or metastasis) was expressed. We experienced a case of glomangiosarcoma form subungual region treated by marginal excision and no recurrence or metastasis was developed untill 1 year and 6 months postoperatively.
