'MUCINOUS ADENOCARCINOMA OF COLON MIMICKING CYSTIC LYMPHANGIOMA: REPORT OF AN UNUSUAL PRESENTATION WITH BRIEF REVIEW OF LITERATURE.'

Retroperitoneal masses present with a diverse group of lesions; ranging from benign to malignant. These lesions can be solid or cystic, single or multiloculated, and the contents may range from serous to mucinous uid. Mucinous adenocarcinoma of retroperitoneum is rare. We present a case of retroperitoneal mucinous adenocarcinoma of colon in a 25-year-old male, mimicking a benign cystic lesion on radiology. Cytology along with histopathology helped in making a denitive diagnosis of malignancy in this case.
