Multiple juvenile polyposis. A report of 2 cases
1Department of Anatomical Pathology, Medical University of Southern Africa, Pretoria.
Insights
Multiple juvenile polyposis, a rare condition, was observed in two Black boys. This study details their cases, highlighting the rectosigmoid colon involvement and colectomy treatment.
Area of Science:
- Gastroenterology
- Pediatric Surgery
- Genetics
Background:
- Juvenile polyposis is a rare hamartomatous polyposis syndrome.
- It typically presents in childhood with gastrointestinal bleeding, abdominal pain, or intussusception.
- Genetic mutations in SMAD4 or BMPR1A are often implicated.
Observation:
- Two cases of multiple juvenile polyposis in Black boys aged 10 and 12 years are presented.
- No family history of polyposis was reported in either case.
- Both patients presented with extensive polyposis primarily affecting the rectosigmoid colon.
Findings:
- Surgical colectomy was performed in both patients.
- The first case involved a sigmoid colon segment with predominantly sessile polyps.
- The second case exhibited polypoid lesions throughout the sigmoid colon and rectum.
Implications:
- This report highlights the infrequent documentation of juvenile polyposis among individuals of Black descent.
- It underscores the importance of considering juvenile polyposis in pediatric patients presenting with colorectal polyps, regardless of ethnicity.
- Further research may be needed to understand potential ethnic variations in the presentation or prevalence of juvenile polyposis.
Abstract:
Two cases of multiple juvenile polyposis in black boys aged 10 and 12 years are described. There was no history of polyposis in the families. In both patients the rectosigmoid part of the large bowel mainly was involved and was treated by colectomy. The first case showed a segment of sigmoid colon studded with polyps, which were predominantly sessile. The second case showed polypoid lesions throughout the sigmoid colon and rectum. This rare phenomenon has been infrequently reported among black people.
