Definition

A benign, well-circumscribed tumor of the pelvicoperineal region composed of a prominent vascular and stromal component, the latter showing myofibroblastic differentiation

Clinical Features

  • Incidence

    Angiomyofibroblastoma is uncommon.

  • Age

    These tumors typically occur in adults over a wide age range. In women, approximately 10% occur following menopause.

  • Sex

    Angiomyofibroblastoma more commonly occurs in women.

  • Site

    These tumors arise in the subcutaneous tissue of the pelvicoperineum, with the vulva being the most common location. Clinically, they are often thought to represent a Bartholin gland cyst. Approximately 10–15% occur in the vagina. In men, they occur in paratesticular soft tissue or the scrotum.

  • Treatment

    Local excision is adequate treatment.

  • Outcome

    Angiomyofibroblastoma is benign. Recurrence is rare even after marginal excision.

Macroscopy

These tumors usually measure <5 cm and are well demarcated but lack a capsule. They typically have a soft to rubbery...
