Differential Diagnosis for a Bleeding Umbilical Mass
- Single most likely diagnosis
- Umbilical granuloma: This is the most common cause of a bleeding umbilical mass, especially in newborns. It occurs when the umbilical stump doesn't heal properly, leading to the formation of a granuloma that can bleed.
- Other Likely diagnoses
- Umbilical polyp: A benign growth that can cause bleeding from the umbilicus.
- Omphalitis: An infection of the umbilical stump that can cause bleeding, discharge, and other symptoms.
- Umbilical hernia with incarceration or strangulation: Although less common, an umbilical hernia can cause a mass and bleeding if it becomes incarcerated or strangulated.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Omphalomesenteric duct cyst or sinus: A congenital anomaly that can cause bleeding, infection, or intestinal obstruction if not treated promptly.
- Umbilical metastasis (Sister Mary Joseph nodule): A rare but potentially life-threatening condition where cancer metastasizes to the umbilicus.
- Rare diagnoses
- Umbilical endometriosis: A rare condition where endometrial tissue grows in the umbilicus, causing cyclic bleeding and pain.
- Umbilical leiomyoma: A rare benign tumor that can cause a bleeding umbilical mass.
- Patent urachus: A congenital anomaly where the urachus (a tube connecting the bladder to the umbilicus) fails to close, potentially causing bleeding or urinary leakage from the umbilicus.
