Teratoma with nephroblastoma is a rare disease. The most common site at which teratoma with nephroblastoma occurs is the kidney. The mechanisms underlying the development of teratoma with nephroblastoma have not been fully elucidated.Patient concerns:
In the current report, we describe the clinical characteristics of a 3-year-old girl with a complaint of a painless abdominal mass in the upper right side of the body. Ultrasonography and computed tomography revealed a cystic-solid mass with a clear boundary.Diagnosis:
Surgical resection and a subsequent pathological examination confirmed that the mass contained teratoma tissues and renal blastemal components, which supports the diagnosis of teratoma with nephroblastoma.Interventions:
The patient underwent an exploratory laparotomy through a transverse abdominal incision. Complete resection of the mass was performed in this patient.Outcomes:
The patient's postoperative course was uneventful and she was discharged on the 8th postoperative day. The girl had no complaints during the 2 years follow-up period.Lessons:
Teratoma with nephroblastoma is a rare entity that typically presents in childhood. Due to its rarity, no standardized criteria have been established for the categorization and treatment of these lesions. However, a complete excision of this tumor allows the diagnosis to be confirmed and lowers the risk of recurrence.
