A 67-Year Old Woman with a Carcinoid Tumor of the Coccyx with Liver Metastases

#392

Introduction: Neuroendocrine tumors (NETs) are tumors of the interface between the endocrine and nervous system. They are characterized by the presence of secretory granules, as well as the ability to produce biogenic amines and polypeptide hormones. The clinical behavior of NETs is extremely variable; they may be functioning or non-functioning, ranging from very slow-growing tumors, which are the majority, to highly aggressive and very malignant tumors. Many case reports of rare sites of primary NETs outside the gastrointestinal tract have been described, as tumors with neuroendocrine characteristics can occur in virtually any organ or tissue. Nevertheless, this is the first case of a metastatic coccygeal carcinoid tumor ever described.

Aim(s): To describe the clinical presentation, diagnosis and treatment of a patient with a carcinoid tumor of the coccyx and with liver metastases.

Materials and methods: Clinical history, laboratory tests, magnetic resonance imaging studies and light microscope micrographs are reviewed.
