Background: True thymic hyperplasia results from stressful situations such as chemotherapy. It commonly presents as an anterior mediastinal mass; cervical location is exceptional. The aim of this work is to illustrate a case of an incidental ectopic cervical thymic hyperplasia in a patient treated for Hodgkin lymphoma.
Case reprt : Here we report a case of a cervical true thymic hyperplasia in a 12-year-old girl who had a Hodgkin lymphoma treated by radiotherapy and chemotherapy. She was referred to our department for a left cervical mass. The PET scan showed a hypermetabolic adenopathy. Mediastinal MRI was unremarkable. The patient underwent resection of the cervical mass under general anesthesia. Pathological examination confirmed the diagnosis of a true thymic hyperplasia.
Conclusion : Residual ectopic tissue may persist during its migration to its final position in the anterior mediastinum. True thymic hyperplasia may result from chemotherapy for lymphoma in the pediatric population. However, its presence in the cervical region is exceptional. Histological examination is necessary for diagnosis if imaging techniques are unable to rule out malignancy.
