Carcinoma Lung Presenting as Sister Mary Joseph’s Nodule

Abstract

Metastatic nodules of the umbilicus from malignant neoplasms are known as Sister Mary Joseph’s nodule and they represent an advanced malignancy. These nodules are mostly adenocarcinomas with the commonest primary sites in intraabdominal organs. Here, we describe case of a patient with squamous cell carcinoma of lung who presented with metastatic umbilical nodule as the initial presentation of the tumor. Metastatic umbilical nodules from lung carcinoma and that too from squamous cell carcinoma are very rare. Patients presenting with umbilical nodules should be investigated without any delay and metastatic nodule should be included in the differential diagnosis especially in elderly patients.
