Infiltrating Metastatic Ductal Carcinoma Initially Presenting as Axillary Lymph Node Metastases Diagnosed with PET/CT and MRI: Case Report and Brief Review of Occult Breast Carcinoma
Introduction The concept of occult breast carcinoma (OBC) was first described in 1907 by Halsted, who described this type of breast cancer to arise from small, undetectable tumours in the breast that had already metastasized to the lymph nodes. Although the breast is the most likely site for the primary tumour, non-palpable breast cancer presenting as an axillary metastasis has been reported, but with a low frequency of less th Read More
