ABSTRACT
Objective To investigate the clinicopathological features of glomus tumor and its differential diagnosis. Methods Clinical, morphologie and immunohistoehemical representations were described in 11 cases of glomus tumor. Results The tumors were located at the hyponychial in 7 cases, forearm subcutaneous in 2 cases, knee subcutaneous in 1 case, gastric antrum forewall in 1 cases. Localized pain was the primary symptom. 9 giomus tumors were histopathologically classified as solid type, and 2 glomangiomatous type. The prominent morphologic features of glomus tumor were as follows the tumor cells were small, round, uniform, the tumor cells arranged around capillary vessel or expansion of the small vein showing nest pattern,some tumor cells in fasciation pattern; focally myxoid change in the stroma were seen. Immunohistochemistry 11 cases were positive for SMA and Vimentin; while other markers including CK, CD117, CD34, CgA, Syn, Desmin, S-100 and HMB45, were all negative. All 11 cases were without any evidence of recurrence or metastasis in followed-up for 12-30 months. Conclusion Glomus tumor is extremely rare. The diagnosis depends on the histology and immunohistochemistry. Glomus tumor is rare in visceral sites. It may be misdiagnosed and needs to he differentiated from other tumors.
