Definition

Hemangioma is a benign vascular tumor.

Clinical Features

  • Incidence

    Hemangioma of the urogenital tract is rare and reports consist mainly of single cases or small series. However, hemangiomas were detected in 8.8% of kidneys removed for end-stage renal disease.

  • Age

    It occurs at all ages, including infants. The median is in the sixth decade.

  • Sex

    Hemangiomas of the kidney and the bladder occur more frequently in males.

  • Site

    Urogenital hemangiomas arise more frequently in the kidney and the bladder.

  • Treatment

    Surgery is the primary treatment. Embolization of the lesion may be considered to reduce the bleeding.

  • Outcome

    Hemangioma is a benign tumor that does not recur after complete excision.

Macroscopy

Grossly, hemangiomas appear as hemorrhagic lesions ranging in size from 0.5 to 9 cm.

Microscopy

Histologically, hemangiomasconsist of a well-demarcated but unencapsulated proliferation of variably sized blood vessels, lined by flattened endothelial cells with very scant...
