Unsafe abortion in adolescents is of great public health challenge and it occupies a large armamentarium in contemporary adolescent reproductive health issues. This case report was that of induced unsafe abortion, done without analgesia and inside a sitting room, in a 15‑year‑old, secondary school girl, nullipara; complicated by gangrenous uterus and bowel for which she had subtotal hysterectomy, bowel resection, and anastomosis. Primary preventive strategies should be the cornerstone of prevention with more emphasis on advocacy for adolescent sexuality and reproductive health education, information, and family planning/emergency contraception.Keywords: Adolescent; complication; unsafe abortio
