Introduction: Glomus tumor are uncommon tumors of mesenchyme consist of cells of the normal glomus body, smooth muscle and vasculature. Glomus tumor often occurs in the skin of distal extremities and visceral organ invasion is rare. We present a 54-year-old female with an accidentally found renal tumor.
Case presentation: A 54-year-old female with past history of dyslipidemia and hypothyroidism. Asymptomatic renal tumor was noted under computed tomography accidentally. The image showed a heterogenous tumor around 4cm in diameter with calcifications and septa in the upper pole of the left kidney. Due to the suspicion of malignancy, she received surgical resection of renal tumor. Immunohistochemical stains were performed with resected tumor cells, which revealed immunoreactivity for Smooth Muscle Actin (SMA) and Muscle Actin. Pathology report showed renal glomus tumor. No adjuvant therapy was given to this patient. There was no recurrence during follow-up so far.
Conclusion: Renal glomus tumor is rare and there are few cases reported before and most cases are benign tumor. Malignant glomus tumor is relative scarce and the diagnosis is based on pathological characteristics. Mainly treatment of renal glomus tumor is surgical resection, either partial or radical nephrectomy. This case demonstrated a benign renal glomus tumor under pathological examination after partial nephrectomy. Prognosis of renal glomus tumor is ideal. The patient was disease-free as yet without recurrence.
