Prise en charge thérapeutique des paragangliomes malins: revue de littérature à travers un cas illustratif

Malignant paragangliomas pose a real challenge for the practitioners. They are rare complex tumors, very heterogeneous in their evolution and prognosis. Given the rarity of this tumor group, there is no consensus on therapeutic management. Through this illustrative case study, we report the case of a 29 year old female patient followed for malignant paraganglioma due to which she initially had surgery. After a six month interval, multifocal recurrence was detected on Octreoscan PET-CT (Positron Emission Tomography- Computer Tomography). The patient underwent monthly injection of Somatuline for one year and then discontinued therapy due to disease progression. Cytoreduction was then performed followed by radiotherapy. After a year, the patient had massive disease progression. Dacarbazine-based chemotherapy was initiated. The patient had an almost complete metabolic response after eight cycles. This study aims to highlight the different therapeutic options in the management of malignant paragangliomas.
