An unusual presentation of carcinoma sigmoid colon

Worldwide approximately 1,200,000 new cases of colorectal carcinoma (CRC) are diagnosed annually, and about half of them died. Lack of exercise along with obesity and consumption of red meat are thought to be associated with the development of CRC. Surgery is the primary modality of treatment which depends on size, site, and stage beside other associated factors. Histopathology along with general condition and extent of disease are stablished as an important prognostic factor. Chemotherapy and radiotherapy are used in the adjuvant and palliative setting. Here, we are reporting an interesting case of sigmoid colon carcinoma presenting as an advanced lesion over a very short span of time along with emphasizing the harm of unnecessary multiple investigations for diagnosis putting in the dilemma to both the patient as well as treating physician. This case also explains the interobserver variability as well as difference between the types of scan as well as reporting.
