Malignant sweat gland tumor of breast arising in pre-existing benign tumor: A case report

Figure 2 Breast magnetic resonance imaging showing a well-circumscribed oval mass of the left subareola. A: The lesion attached to cutaneous layer of subareola and compressed the breast parenchyma. It showed a T1 hyper-intensity compared to signal in muscle. Thin fatty layer was seen between the mass and breast parenchyma (arrowheads). Breast implant was noted in the retromammary area; B: On T2-weighted axial image, the lesion showed a high signal intensity; C, D: On post-contrast fat saturation T1-weighted coronal (C) and sagittal (D) images, the mass showed a well-circumscribed thin and even enhancing wall. There was a small enhancing mural component in the inner wall of the mass (arrows).
