title: Myxoma of the upper leg originating from an appendiceal mucinous neoplasm: A case report.
abstract: Myxoma is rare in the upper leg. The current study presents the case of a large tumor in the right upper leg. The tumor extended to pelvic cavity and was found to be connected with a cystic and solid neoplasm that was adjacent to the ascending colon in the right lower quadrant. The large tumor of the upper leg had existed for 15 years and had ulcerated through the skin 4 days prior to admittance. Palliative surgery was performed, with histological findings of a myxoma. Since appendiceal mucinous neoplasms may invade organizations outside of the mucous layer of the appendix and cause secondary peritoneal myxoma, this myxoma of the upper leg probably originated from an appendiceal mucinous neoplasm.
