case_images: Breast ultrasonography. (A) A large mass was seen on the surface of the right chest wall, the thickest part of which was about 21.1mm, and the inner part of the mass was uneven and hypoechoic. (B) color Doppler flow imaging(CDFI): abundant blood flow signal is seen inside the mass.

case_images: Ultrasonography showed an inhomogeneous hypoechoic mass in the right breast, accompanied by abundant blood flow signals ( Figure 1 ).
case_images: Chest enhanced scan. (A) A soft tissue mass with irregular shape and cauliflower-like changes was seen in the right breast area, which was connected with the nipple and showed obvious uneven enhancement. (B) The tissue behind the nipple shows thickening and strengthening.

case_images: Histopathologic examination. (A) Papillary and pestle-and-ball heterogeneous hyperplasia of squamous epithelium with koilocyte formation, chronic suppurative inflammation in some areas, and hyperplasia and dilatation of mammary ducts. (B) Squamous epithelial verrucous and papillomatous hyperplasia with some areas of carcinoma, carcinoma areas of highly differentiated squamous cell carcinoma with superficial mesenchymal infiltration of skin and soft tissues.

case_images: Postoperative pathological analysis showed that the lesion tissue was consistent with squamous epithelial warts with squamous cell carcinoma ( Figure 3 ).
