Objectives: After studying the article titled “Sister Mary Joseph Nodule: A Cohort Study of an Unusual Umbilical Mass,” you will be able to:
Identify the characteristics associated with a Sister Mary Joseph nodule
Discuss the likely metastatic pathways responsible for a Sister Mary Joseph nodule
Develop a protocol for a complete sonographic examination when there is a suspicion of a Sister Mary Joseph nodule
A Sister Mary Joseph nodule is typically found during a third-trimester fetal sonographic examination in neonates in pediatric patients in adults
A Sister Mary Joseph nodule is a malignant lesion with a poor prognosis a malignant lesion with good long-term survival a malignant lesion easily resected a benign lesion that is easily removed surgically
A Sister Mary Joseph nodule is typically found as a chest wall mass in the periumbilical region in the groin region in the supraclavicular region
The most common physical finding associated with a Sister Mary Joseph nodule is a 5- to 10-cm soft mass an inflamed, painful protruding mass a large, painful edematous mass a firm, painless nodule
The most common primary tumor site for a metastatic Sister Mary Joseph nodule is lung gastrointestinal system female reproductive sites breast
The most common cause for delay in the diagnosis of a Sister Mary Joseph nodule as a metastatic lesion is because the mass is considered an umbilical hernia a lipoma a hematoma a ventral hernia
The most likely route of metastasis for a primary cancer to the periumbilical region is thought to be the arterial circulation the venous circulation direct extension the lymphatic system
Definitive diagnosis of a cancerous lesion in the periumbilical region is made by CT MRI sonography biopsy
Average survival after diagnosis of a metastatic Sister Mary Joseph nodule is less than 2 months 6 months 10–11 months 24 months
The term Sister Mary Joseph nodule was first used in 1846, in the first report of cancer involving the umbilicus 1928, by Dr William Mayo of the Mayo Clinic 1939, after the death of Sister Mary Joseph 1949, in a textbook on physical examination findings
