Introduction: Choriocarcinoma is a fast-growing, malignant, and rare gestational trophoblastic tumour. Although the prognosis of this tumour is very good, serious complications such as preeclampsia and haemorrhagic shock can occur. Case Presentation: A 31-year-old female patient, who was diagnosed with choriocarcinoma, returned to the hospital with severe abdominal pain a few days after her first cycle of chemotherapy treatment. Upon further examination, the presence of free fluid in her abdomen and high β-hCG levels were identified. Consequently, an emergency laparotomy was performed discovering that the uterine tumour, which was adherent to the right colon and appendix, had ruptured. A total hysterectomy and right oophorectomy were performed, and the patient is now doing well. Conclusions: This case elucidates the need for improved diagnostic methods and classification systems along with swift management of gestational trophoblastic diseases.

Hirschsprung's disease is a rare disease characterized by the complete absence of ganglionic cells in the colon, thereby causing loss of peristalsis movement of the bowel. Most cases are diagnosed before the age of one. Here, we present a case of a newborn baby boy who was not feeding well and then developed a distended abdomen and began bilious vomiting. Blood mucoid stools were also observed. The diagnosis of Hirschsprung's disease was confirmed through a full-thickness rectal biopsy, and the Duhamel surgical procedure was performed as a course of treatment all within the first few days of birth. No complications were reported, and the baby was safely discharged after seven days. This case demonstrates the importance of timely treatment after prompt diagnosis due to the early recognition of the severe symptoms. Even though this disease is rare, pediatricians should be trained to recognize and treat the child to prevent further detrimental outcomes.
