Angiomyxoma

Last edited: 4/16/2026

Overview

Aggressive angiomyxoma (AAM) is a rare, locally aggressive soft tissue neoplasm typically found in the pelvic region, affecting both sexes but predominantly women. It presents as a slowly growing, polypoid or cystic mass with a tendency to recur due to incomplete excision 1.

Diagnosis

  • Clinical Presentation: Slowly growing, polypoid or cyst-like tumor in the vulva, vagina, pelvic floor, or perineum 1.
  • Demographics: Predominantly affects women aged 18 to 63 years; also seen in men 1.
  • Histology: Characterized by stellate and spindle-shaped cells in a collagenous stroma with abundant hyaluronic acid; notable vascular component with medial hypertrophy 1.
  • Imaging: Not specified in the abstract; typically requires MRI or CT for detailed anatomical assessment 1.
  • Immunohistochemistry: Not detailed in the abstract; typically confirms fibroblast-like nature of neoplastic cells 1.
  • Electron Microscopy: Neoplastic cells resemble fibroblasts rather than myofibroblasts 1.
  • Management

  • Surgical Excision: Complete surgical removal is crucial to prevent recurrence 1.
  • Recurrence Management: Close follow-up required due to high recurrence rates (6/9 cases recurred within 9-84 months) 1.
  • Adjuvant Therapy: Not specified in the abstract; no mention of chemotherapy or radiation 1.
  • Special Populations

  • Pregnancy: Not addressed in the provided abstracts 1.
  • Pediatrics: Not addressed in the provided abstracts 1.
  • Elderly: No specific considerations noted; management principles likely similar to other age groups 1.
  • Comorbidities: No specific guidance provided regarding comorbidities 1.
  • Key Recommendations

  • Ensure Complete Surgical Excision: Essential to minimize recurrence risk (Evidence: Moderate) 1.
  • Implement Long-term Follow-up: Due to high recurrence rates, regular monitoring is necessary post-surgery (Evidence: Moderate) 1.
  • Consider Multidisciplinary Approach: Given the aggressive nature and recurrence potential, collaboration with surgical specialists is advised (Evidence: Expert opinion) 1.
