Unusual Uptake of 131I in a Cutaneous Benign Fibrous Histiocytoma in a Patient With Thyroid Cancer

Clin Nucl Med. 2018 Jan;43(1):e31-e32. doi: 10.1097/RLU.0000000000001865.

Abstract

A 52-year-old man with papillary thyroid cancer underwent total thyroidectomy and subsequent I remnant ablation. The postablation whole-body radioiodine scanning showed an unexpected focus on the upper right arm. SPECT/CT found that the abnormal focus of radioactivity was from body surface. Histopathology confirmed the diagnosis of benign fibrous histiocytoma.
