(a) Ultrasonography shows a hypoechoic area in the lateral region of the right. (b) Magnetic resonance imaging shows enhanced lesions in the lateral region of the right breast.

Ultrasonography (US) revealed a hypoechoic area in the lateral region of the right breast, which was diagnosed as ductal carcinoma in situ (DCIS) using vacuum-assisted biopsy (Figure 1(a)). Magnetic resonance imaging (MRI) revealed wide enhanced lesions in the lateral region of the right breast, with a maximum diameter of 76 mm (Figure 1(b)).
Ultrasonography shows a solid mass lesion subcutaneously in the lateral region of the right breast.

The largest diameter of the mass was 1.0 cm, and it had a smooth surface (Figure 2).
(a) Contrast-enhanced computed tomography shows enhanced solid mass lesions in the deep tissue in addition to the superficial tissue of the reconstructed breast. (b) Second-look ultrasonography shows the mass in deep adipose tissue of the reconstructed breast.

CT revealed multiple enhanced solid mass lesions in the subcutaneous and deep tissues of the reconstructed breast (Figure 3(a)). On second-look US, the mass in the deep tissue of the reconstructed breast was 1.2 cm in diameter (Figure 3(b)).
(a) Histopathological findings. The macroscopic image shows multiple tumors localized within the superficial and deep adipose tissues of the reconstructed breast (red dotted circle). (b) The microscopic image of the deep tumor shows tumor cells exhibiting typical features of IMPC separated by a mesh-like stroma (H&E staining, x40).

Macroscopically, the tumor was localized within the superficial and deep adipose tissues of the reconstructed breast (Figure 4(a)). Histopathology of a deep tumor identified IMPC with a tumor diameter of 1.5 cm (Figure 4(b)).
