“…Most important is hemangiopericytoma; it has a potentially malignant nature, 11 as opposed to the virtually consistently benign nature of the glomus tumor. Thus, with one anecdotal exception, 28 examples of metastatic glomus tumors have not been reported despite the occasional vascular expansion, 3,18,20 as also demonstrated in the present case. Even recurrences seem to remain a local problem.…”

Glomangiosarcoma of the hypothenar eminence: a case report

“…Recurrences are infrequent and metastases have been seen in 5 cases [3,4,6,12,18]. All of them were glomangiosarcomas arising de novo, so this group may be considered the most aggressive, with a metastases rate of 52.5%.…”

“…Metastases are reported and the first case was described by Kreutz in the maxilla, with a large primary mass (10 × 5 × 5 cm) of the thigh [12].…”

“…This neoplasm may appear in different anatomical locations, though it is most frequently reported at the lower extremity [2,10,12,13,14,15,18].…”

Lower Extremity Glomus Tumors: Comprehensive Review for Surgeons
