Background: Generally, young-onset CRC is the “hallmark” of hereditary CRCs with highly penetrant germline mutations. However, the bulk of young-onset CRCs appear to be sporadic and therefore the molecular mechanisms driving cancer initiation and progression are unclear.

Discussion- Young patients present with more advanced-stage disease at diagnosis compared with older patients. The diagnosis of CRC in young patients is usually delayed because it's seldom suspected. Acute bowel symptoms necessitate immediate exploration at which era perforation of the massive bowel with multiple metastatic deposits may be observed. Ileus by tumor occurs more frequently in adolescents than in adults with this cancer.

Conclusion- A 17-year-old female patient with abdominal pain perforation and colon obstruction thanks to sporadic carcinoma with mucinous histology.

Colon Cancer of a Bangladeshi 17-Year-Old Girl without Known Genetic Predisposition Following Enteric Fever Induced Complication.


17 years 9 months old young lady dancer from Bangladesh presented to a tertiary hospital in Dhaka with complaints of pain in the abdomen with distension. She had also a history of lower limb weakness following fever 3 months back and was clinically diagnosed as GBS wherefrom she recovered spontaneously with supportive care. She underwent computer tomography of the abdomen pelvis as ultrasonography failed to detect the cause of her abdominal pain except for a polyp in the gallbladder; that revealed- Neoplastic narrowing in left mid colon dilated bowel loops containing air-fluid levels. Colonoscopy was inconclusive to detect any focal lesions in the colon. Then she moved to another hospital and was clinically diagnosed as a case of mechanical obstruction/ enteric fever-induced perforation / burst appendix. After admission, she found to have septicemia with ARDS. After correction, she underwent her first laparotomy followed by segmental resection of the terminal ileum with illeo-colic anastomosis with proximal defunctioning ileostomy with appendectomy with peritoneal toileting. Laparotomy revealed – severe ileitis due to enteric fever was noted at the entire ileum. Multiple patchy gangrenous point and multiple perforations were found up to 60 cm of distal ileum just proximal to the ileocecal valve and then resection of that segment and ileocolic anastomosis with loop ileostomy was done. Her HPR revealed – Ileal perforation with peritonitis. She developed well and was discharged.

After one month of her initial laparotomy, she was re-admitted for her ileostomy closure that was performed. Two days of post-closure due to abdominal pain, a second re-laparotomy was performed. Per operative, findings were perforation at the previous anastomotic site and then control fistula was done. Ileostomy closure anastomosis was found healthy. After that postoperative, she was well and improved. After that she again developed intestinal obstruction and a colonoscopy was performed that revealed mucosal swelling, slight irregularity and ulceration at the distal descending colon. Biopsy was taken and HP showed poorly differentiated adenocarcinoma, diffuse type. For the staging purpose, PET CT did that revealed - No hypermetabolic lesion is detected in the post-operative site of the colon nor any hypermetabolic abdominopelvic lymph node suggest no local residue, dilated pelvis & ureter, No other visceral, nodal, or osseous hypermetabolic lesion is noted.

Then she was planned for an operative procedure for her malignancy on the transverse colon. After 1 month of her 2nd laparotomy, she underwent 3rd definitive operation- a left hemicolectomy with a proximal defunctioning loop ileostomy was done. Per operatively- there were no ascites, no peritoneal seedlings, the liver was found healthy and free from any form of macro metastatic nodules. There was extensive interloop adhesion was identified, ascending, transverse and descending colon found hugely distended and full of fecal matters. A stricture-like growth was distal descending colon which causes luminal narrowing and resulting in complete obstruction. Few pericolic LNs were found enlarged and hard in palpation, para-aortic LNs and LNs along the axis of IMA were not palpable.

Histopathology revealed an annular ulcerative growth in the colonic mucosa that was about 4.5cm showed poorly differentiated adenocarcinoma, Tumor invades through the visceral peritoneum with lymph node metastasis, 11 out of 11 regional LNs showed metastasis, LVSI- Identified but PNI- Not seen. Histological features suggestive of Microsatellite instability not identified. Further IHC was done that was expressive for CDX2 and CK20 and immunonegative for CK7 which confirmed colonic adenocarcinoma. Her pathological stage- pT4aN2bMx, IIIC.



 According to GLOBOCAN 2018 data colorectal cancer (CRC) is the 3rd most commonly diagnosed and 2nd most deadly malignancy in the world [1]. In 2020, it is estimated that there will be 147950 new cases of colorectal cancer which represents 8.2% of all new cancers cases in the United State2. An estimated 53,200 people will die of this disease in 2020 which represents 8.8% of all cancer death [2]. Five years relative survival of CRC PS 64.6%. CRC is more common in men than women and among those of African American descent [3]. CRC is most frequently diagnosed among people aged 65-74 years, the median age of diagnosed 67 years [2]. The rate of new cases of CRC was 38.2 per 100,000 men and women per year2. For CRC death rate increases with age. CRC is the 2nd leading cause of cancer death in the United State [4]. The percent of CRC deaths is highest among people aged 75-84 years, the median age at death 73 years [5]. The death rate was 13.9 per 100,000 men and women per year2. Approximately 4.2% of men and women will be diagnosed with colorectal cancer at some point during their lifetime [2]. In 2017, there were an estimated 1, 34,087 people living with CRC in the United State [2]. In the United State CRC incidence and mortality has been decreasing among individuals older than 55 years, and this has been largely attributed to population-based CRC screening recommendations in place since the 1980s [6-7]. However, the incidence of CRC among the adolescent and young adult (AYA) population (Particularly those 18-40 yrs) has shown an alarmingly opposite trend. In this population, CRC is being increasingly diagnosed, according to independent analyses from the following two major cancer databases [6, 8]. In the United State the SEER Program and the National Cancer Database (NCDR) [9, 10].

In Canada, A slight decline was observed in the colon and rectal cancers during 2005–2015, regardless of age at diagnosis [24].

For colon cancer, the adjusted incidence rates increased annually over roughly the past four decades by 2.4% in those aged 20 to 29 years, by 1% in those aged 30 to 39 years and by 1.3% in those aged 40 to 49 years [6]. Given the projection of current incidence rates to the year 2030, the largest predicted increase in colon 90% cancer incidence will occur in the 20 to 34 years age group, whereas the incidence rate for colon will decrease by 41%, for those older than age 50 years [11].

This case of colonic cancer aged 17 years is the uncommon presentation and hence should be of interest to clinicians to increase their index of suspicion as early cases are potentially curable.



Although CRC is one of the most frequent tumors in adults, patients rarely occur before the age of 20 years,12-14 with an annual incidence of only one to two cases per one million people in the US, according to only about 80 cases per year [15].

Colorectal carcinoma (CRC) rarely occurs in children and adolescents. It is generally considered to be a disease of an older person; more than 90% of CRC patient is above 55 years old.16 Groups of young patients known to be at increased risk for colorectal carcinoma are those with inflammatory bowel disease, hereditary nonpolyposis colon cancer (HNPCC) and polyposis syndromes of the gastrointestinal tract [17].

We reported this case as a young age sporadic colorectal cancer (YSCC) because the patient was 17 years old and had neither family history of colon cancer nor any other malignancy, and showed MSS (microsatellite stability) without any germline abnormality. She had no risk factors such as inflammatory bowel disease or multiple colon polyp.

YSCC also presents features similar to adult colorectal cancer, such as abdominal pain, altered bowel habit, weight loss and rectal bleeding18. In some pediatric reports, acute presentation, including intestinal obstruction and acute pain mimicking appendicitis account for almost 50% of presentation [19].

However, young patients present with more advanced-stage disease at diagnosis compared with older patients. This may be because of delayed diagnosis and poorer pathological findings16. Recent evidence showed that the incidence of colorectal cancer decreased among older adults, yet this decline didn't appear in adults younger than 50 years. The evaluation of age-related incidence trends of colon and rectal cancers in China during 2005-2015 decreased by -2.2% (95%CI: -3.1, -1.3) per year [25].

The diagnosis of CRC in young patients is often delayed because it is seldom suspected. Acute bowel symptoms necessitate immediate exploration at which time perforation of the large bowel with multiple metastatic deposits may be observed. Intestinal obstruction by tumor occurs more frequently in adolescents than in adults with this cancer [20-21].

Another distinct feature of YSCC its pathological characteristics. It has a higher proportion of patients with nodal metastasis, distant metastasis and poorly differentiated tumors. YSCC also shows aggressive tumor biology, including mucinous component, signet-ring cell carcinoma, and perineural, vascular, and lymphatic invasion [22].

Most CRC in adults is moderately differentiated or well-differentiated adenocarcinoma.14 In contrast, more than half of reported cases of childhood CRC are poorly differentiated mucinous adenocarcinoma and many are of them signet-ring cell type [20,23].

In conclusion, we reported a case of a 17-year-old female patient with abdominal pain perforation and colon obstruction due to sporadic colon cancer with mucinous histology.

She had absolutely no predisposing condition. Her histopathological report revealed multiple regional nodal [11] involvement with lymphovascular invasion. Her cancer diagnosis was delayed by the physician’s failure to consider malignancy in the differential diagnosis. Therefore, even in low-risk young patients, symptoms such as unexplained abdominal pain, rectal bleeding, or change in bowel habits should be considered a representation of significant colorectal lesions.

This case warrants increased awareness and aggressive pursuit of symptoms in young patients without any risk features.
