A Rare Case of Neuroendocrine Tumor with Liver Metastasis

Öz

Neuroendocrine tumors arise from neuroendocrine system cells, and constitute a heterogeneous group of neoplasms. In this case report, a case of non-functional neuroendocrine tumor presented with diffuse liver metastases is discussed. Radiological and nuclear medicine examinations of a 61-year-old male patient admitted to our clinic with complaints of abdominal pain and abdominal swelling revealed multiple hypodense mass lesions consistent with diffuse metastasis in the liver. Liver biopsy showed neuroendocrine tumor in hepatic metastases. Surgical resection as a treatment option was not applicable because of her advanced age and diffuse liver metastases. Long-acting somatostatin analogue was prescribed for the patient. In the follow-up, despite reduction in the patient’s symptoms. In conclusion, it should be kept in mind that although neuroendocrine tumors, which are rare, have been asymptomatic until recently, despite their slow course, they may present as non-functional with extensive liver metastasis.

Nadir Karaciğer Metastaz Nedeni; Nöroendokrin Tümör (Bir olgu Nedeniyle)

Öz

Nöroendokrin tümörler, nöroendokrin sistem hücrelerinden köken alan heterojen bir neoplazma grubundan oluşmaktadırlar. Bu olgu sunumunda diffüz karaciğer metastazı ile seyreden non-fonksiyone bir nöroendokrin tümör olgusu tartışılmıştır. Kliniğimize karın ağrısı ve karında şişlik şikayetleri ile başvuran 61 yaşındaki erkek hastanın yapılan radyolojik incelelemelerde karaciğerde diffüz metastazla uyumlu çok sayıda hipodens kitle lezyonları saptandı. Yapılan karaciğer biyopsisi, hepatik nöroendokrin tümör metastazı ile uyumlu bulundu. Diffüz karaciğer tutulumu birlikte hastanın yaşının ileri olması nedeni ile cerrahi rezeksiyon düşünülmedi. Hastaya uzun etkili somatostatin analoğu başlandı. Takiplerde hastanın semptomları geriledi Sonuç olarak nadir görülen nöroendokrin tümörleri yavaş seyrinin aksine tümüyle yakın zaman kadar asemptomatik seyretmesine karşın, yaygın karaciğer metastazıyla birlikte afonksiyone olarak prezente olabileceği göz önünde bulundurulmalıdır.
