Multiple Cutaneous Leiomyomas Showing Increased FDG Uptake

Clin Nucl Med. 2020 Oct;45(10):827-829. doi: 10.1097/RLU.0000000000003213.


Cutaneous leiomyomas are rare, sporadic, or inherited benign tumors arising from smooth muscle cells of the skin associated with various disorders. We present a case of multiple cutaneous leiomyomas showing increased FDG uptake with SUVmax of 19.9. This case indicates cutaneous leiomyoma should be considered as a rare differential diagnosis in patients with hypermetabolic cutaneous lesions. Careful correlation with clinical history is needed to avoid misdiagnosis.
