neoplasm
• both nulliparous and multiparous females develop mammary tumors with high penetrance
• mammary pads from 6- to 8-month old females show no evidence of preneoplastic growth, indicating that tumor growth is extremely rapid after initiation
• mammary tumors show diverse histology with basal characteristics and include mammary adenosquamous carcinoma with solid and tubular patterns, mammary squamous cell carcinoma, mammary myoepithelioma, hamangiosarcoma, mammary adenocarcinoma with squamous metaplasia
• solid features are present in 30% of tumors, but in several cases, the solid phenotype is intermixed with squamous metaplastic cells
• significant squamous metaplasia is seen in 65% of mammary tumors
• tumors are often estrogen receptor-positive and progesterone receptor-negative
• mammary adenocarcinoma with squamous metaplasia or/and with solid patterns
• mammary adenocarcinomas show high levels of Met amplification and trisomy
• mammary squamous cell carcinoma
• undifferentiated mammary sarcomas
• mammary hamangiosarcoma
• mammary myoepithelioma
