Glomus tumor of renal pelvis: a case report and review of the literature

Malignant glomus tumor of kidney: the first reported case and review of literature

“…The first case of a glomangiomyoma of the renal capsule was reported by Billard et al [4]. This was followed by Siddiqui et al [5], who reported a glomangioma of the renal parenchyma, and then Herawi et al [6] reported a glomus tumor of the renal pelvis and proximal ureter. These reports preceded a case series [7] of 3 benign glomus tumors, which included a solid glomus tumor, glomangioma, and glomangiomyoma.…”

Infiltrating glomus tumor of uncertain malignant potential arising in the kidney

“…Review of the published literature revealed rare involvement of the kidney, with only 6 examples of benign glomus tumor being reported. The first report being by Billard [6] of a glomangiomyoma of the renal capsule, followed by a case report of glomangioma of the renal parenchyma by Siddiqui [7], and glomus tumor of the renal pelvis and proximal ureter by Herawi et al [8]. These reports preceded a case series [9] of 3 benign glomus tumors, including a solid glomus tumor, glomangioma and glomangiomyoma.…”

“…However, occasionally glomus tumors show unusual features, such as large size, location in deep soft tissue or viscera, infiltrative growth pattern, and multicentricity. There are some reported cases of primary benign glomus tumors [6][7][8][9] in the kidney despite this being an uncommon location for mesenchymal tumors. This case differs from the published cases in being a glomus tumor of uncertain malignant potential.…”

Malignant glomus tumor of the stomach with multiorgan metastases: Report of a case

“…1 Although the usual location of a glomus tumor is either the dermis or subcutis of the extremities, it can also infrequently occur in internal organs such as the mediastinum, lung, trachea, and stomach. [1][2][3] Most glomus tumors are benign and solitary but very rarely they have been considered to be malignant ("glomangiosarcoma") based on such histological features as nuclear atypia, necrosis, and mitotic activity. [4][5][6] Despite having the histological features of malignancy, they usually do not metastasize.…”
