Abdominal tuberculosis with a Pseudo-Sister Mary Joseph nodule mimicking peritoneal carcinomatosis

Umbilical nodule - A not always innocuous abdominal finding

ABSTRACT

Sister Mary Joseph's nodule is an umbilical nodule found in patients with metastatic abdominal cancers. It is quite rare finding and needs a high index of suspicion for diagnosis. Detection of Sister Mary Joseph's nodule should warrant widespread search for abdominal carcinoma and it universally carries quite poor clinical prognosis. Here, we describe the case of a 28-year-old patient who presented with Sister Mary Joseph's Nodule and was found to have metastatic signet ring cell gastric carcinoma on investigation. A brief discussion about this rare condition is also presented.

Calcified Sister Mary Joseph nodule as the presenting complaint of advanced low-grade serous ovarian cancer

A healthy 38-year-old woman presented with a hard umbilical mass that has been growing for a few months in duration with no other significant symptoms and signs. Computed tomography images identified a lobulated densely calcified umbilical mass, left ovarian cysts, a subcentimeter calcified omental nodule, and nonspecific punctate pelvic calcifications. Histopathology of the mass revealed low-grade serous carcinoma with postsurgical diagnosis of International Federation of Gynecology and Obstetrics (FIGO) stage IV ovarian cancer. This case presentation emphasizes the importance of increased awareness of interpreting radiologists of a seemingly benign appearing imaging finding such as umbilical calcification on CT as a sign of intra-abdominal/pelvic malignancies.
