Fine‐needle aspiration cytology of Sister Mary Joseph's (paraumbilical) nodules

During a period of 5 years (2001-2005), six cases of Sister Mary Joseph's nodule (umbilical metastasis) were diagnosed by fine needle aspiration cytology (FNAC). In all the cases, FNAC of umbilical nodules was the first investigation and subsequently the patients were investigated for the primary tumor. The primary carcinoma was found in the stomach in three cases, ovary in two cases and one case was of non-Hodgkin's lymphoma. Based on our findings, we suggest FNAC as an initial diagnostic procedure in cases suspected of umbilical metastasis. It is not only simple, fast, accurate and inexpensive but can also save the patient from other invasive diagnostic procedures.
