Detection of Recurrent Cutaneous Angiosarcoma of Lower Extremity with 18F-Fluorodeoxyglucose Positron Emission Tomography-Computed Tomography: Report of Three Cases
A 72 year old male developed 5 × 3.2 cm purplish-red cutaneous papule in the posterior aspect of left lower limb. There was no lymphedema. The tumour was resected and histopathology revealed angiosarcoma. Staging investigations at the time of surgery were negative. The patient presented with stiffness and discomfort at the operated site one year later. 18F-FDG PET-CT was done. It revealed cutaneous thickening with increased 18F-FDG uptake (SUVmax-3.3) in the left popliteal region [-] but no distant metastasis []. 18F-FDG PET-CT was suggestive of local recurrence only. The patient underwent surgery for removal of the tumour and is doing fine at 18 months follow up.
