Living with Pelvis syndrome

A rare condition present from birth with a skin growth near the bottom, and differences in the genitals, spine, kidneys, and anus.

Understanding Pelvis syndrome

PELVIS syndrome is a rare condition that combines several differences in the pelvic area, present from birth.

The name stands for perineal hemangioma, external genitalia malformations, lipomyelomeningocele, vesicorenal abnormalities, imperforate anus, and skin tag. In plain terms, it involves a strawberry-like skin mark near the bottom, differences in the genitals, a fatty growth with a spinal sac, kidney and bladder differences, a closed anus, and skin tags. Signs are seen in newborns and infants.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Strawberry mark (hemangioma)
  • Closed or misplaced anus
  • Differences in the genitals
  • Missing or extra kidney
  • Urine flowing backward (vesicoureteral reflux)
  • Skin tags

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists, cancer specialists, digestive system specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
