Abstract:
Cutaneous metastases of primary internal malignancies are rare, with an incidence of 0.7% to 10.4%. Cutaneous manifestations due to breast cancer are the most common metastases dermatologists observe, with a prevalence of 2.4% and an incidence of 23.9%. Presence of cutaneous metastases is usually a late event in disease progression, indicating grave prognosis. Recognition of cutaneous breast cancer metastases significantly alters therapeutic plans, especially when the disease was thought to be successfully cured. F-FDG PET CT imaging can detect cutaneous metastasis and sites of distant metastases and monitor response to therapy. We report 3 patients with cutaneous-predominant breast carcinoma seen by FDG PET/CT.
