Timely Diagnosis Helps Save 10-Year-Old from Rare 900g Tumor at Rainbow Children’s Hospital, Chennai

Chennai: Rainbow Children’s Hospital has successfully treated a 10-year-old boy diagnosed with a rare and high-risk mediastinal germ cell tumor weighing nearly 900 grams, underscoring the importance of early diagnosis in pediatric conditions that may initially present with mild symptoms.

The child was initially treated for recurrent chest infections before further evaluation revealed a serious underlying condition. A multidisciplinary team conducted detailed investigations, including an ultrasound-guided biopsy, which confirmed a mediastinal germ cell tumor. The diagnosis was supported by significantly elevated alpha-fetoprotein (AFP) levels, indicating malignancy.

The patient underwent five cycles of chemotherapy over three months to reduce tumor size. However, the mass continued to occupy more than 75% of the chest cavity, necessitating surgical intervention due to its proximity to the heart and major blood vessels.

According to Dr. Dhinesh Balaji J D, the surgical team opted for an open chest procedure via sternotomy to safely access and remove the tumor. The approach, commonly used in cardiac surgeries, allowed better visualization and protection of critical structures, ensuring complete removal without complications.

The tumor, weighing approximately 850–900 grams, was successfully excised. The child required ventilator support for 24 hours post-surgery, resumed oral intake the following day, and was discharged within four days. Follow-up imaging conducted several weeks later confirmed no residual tumor.

Dr. Nandhini G highlighted the role of coordinated multidisciplinary care, noting that expertise across pediatric surgery, oncology, anesthesia, and critical care contributed to the successful outcome.

Gunasekhar C stated that the case reflects the hospital’s focus on early diagnosis and timely intervention, particularly in complex pediatric conditions.

Medical experts note that mediastinal germ cell tumors are rare and often develop without obvious symptoms. They emphasize that persistent respiratory issues or unexplained breathing difficulties in children should be evaluated promptly to rule out serious conditions.

The case involved a team of specialists across multiple disciplines, highlighting the importance of collaborative care in managing complex pediatric cases.
