Primary Hepatic Neuroendocrine Tumor and its Metastasis to Breast; Case Report of an Unusual Malignancy
Introduction: Neuroendocrine tumors (NETs) are rare tumors with varied clinical presentations. Entero-pancreatic and respiratory systems are usually involved but it can also affect unusual sites like the liver. Purpose: This paper presents a case of a 45 years female who developed progressive and disabling symptoms of mass effect and carcinoid but remained undiagnosed for many years due to extremely low suspicion of such a tumor in liver. Methods: Diagnosis was made after extensive radiological, histopathological, and biochemical investigations. By that time, disease had spread to her breast which is also not a typical feature of NETs. Findings: Diagnosis of rare tumors at an unusual site is challenging and requires high clinical suspicion and appropriate workup.
