Q: Which of the following tumors is known for its potential for spontaneous regression?

Malignant melanoma. ***Osteogenic sarcoma*** - Osteogenic sarcoma, or **osteosarcoma**, is a **malignant bone tumor** that typically does not resolve spontaneously and often requires aggressive treatment [1]. - It commonly presents with **pain and swelling** in long bones, and its prognosis is poor without intervention. *Retinoblastoma* - Retinoblastoma can exhibit **spontaneous regression**, especially in bilateral cases, where the tumor may shrink without treatment over time. - It primarily affects the **retina** in children, ideally diagnosed early to preserve vision and life. *Cholangio carcinoma* - Cholangio carcinoma is an aggressive form of **bile duct cancer** that does not resolve spontaneously and usually has a poor prognosis. - Symptoms typically include **jaundice** and bile duct obstruction, requiring surgical intervention. *Malignant melanoma* - Malignant melanoma is a highly aggressive skin cancer that does not undergo spontaneous resolution and often metastasizes quickly. - Early recognition is crucial for treatment, as it is associated with significant **morbidity and mortality**. **References:** [1] Cross SS.
