Nasopharyngeal cyst after adenoidectomy in a child with liver transplantation

Summary 

We report a very unusual case of a liver transplanted child referred to our Department under clinical suspicion of malignancy. The patient underwent an adenotonsillectomy under general anesthesia without perioperative problems. The post-operative pathological diagnosis was follicular hyperplasia.

Six months later, the patient had a progressive impairment of his breathing. Oropharyngeal examination and magnetic resonance imaging showed a cyst mass hanging behind the soft palate. The patient was scheduled for excision-biopsy of the cystic mass, which was performed without complications. Pathologic diagnosis of the tissue removed in this second operation was granulation tissue. The child is alive and well 5 years after the last surgical procedure.
