Abstract

Malignant melanoma is an aggressive tumor with poor prognosis that can have widespread metastases at presentation. Melanoma is known to undergo neuroendocrine differentiation. We report a case of a 60-year-old woman with malignant melanoma showing a metastatic lesion in the thyroid expressing somatostatin receptors as evident by Ga-DOTANOC PET/CT and metabolically active widespread subcutaneous metastases on F-FDG PET/CT imaging.

摘要

恶性黑色素瘤是一种预后不良的侵袭性肿瘤，其在发病时可能已经广泛转移。众所周知，黑色素瘤会发生神经内分泌分化。我们报告了一例 60 岁女性恶性黑色素瘤病例，其甲状腺转移病灶表达生长抑素受体，Ga-DOTANOC PET/CT 可见，F-FDG PET/CT 代谢活跃的广泛皮下转移。
