CARCINOMA COLON SIGNET-RING CELL TYPE: A RARE CASE REPORT

ABSTRACT

Carcinoma colon ranks third among the commonest cancer in the world, while seen less common in the Asian countries however lately an increasing trend has been observed. Majorly the elderly population is at an increased risk of colon cancer however early onset of the disease has also been observed in past few years. Various histologic subtypes with different prognoses are present, but the most common histological type is Adenocarcinoma (1). Signet-ring cell carcinoma (SRCC) is a known rare subtype of colorectal carcinoma (< 1%) officially recognized by the WHO, mucinous types are aggressive with poor outcomes and are most commonly diagnosed around the fourth to fifth decade of life comprising only 1% of colorectal cancers. So we report a case of a 40-year-old male with adenocarcinoma colon of signet ring cell type. The patient presented with localized abdominal discomfort with only generalized weakness and fatigue which was later evaluated to be a near-obstructing right-sided colonic mass. Patient was taken up for surgery and was found to have diffuse carcinomatosis
