Uroplakin II Expression in Breast Carcinomas Showing Apocrine Differentiation: Putting Some Emphasis on Invasive Pleomorphic Lobular Carcinoma as a Potential Mimic of Urothelial Carcinoma at Metastatic Sites

<div>Histological findings. (a) IPLC case 2: nuclear enlargement and eosinophilic cytoplasm observed in tumor cells (×400). (b) cILC case 2: nuclear enlargement of the tumor cells is modest compared with that of IPLC. Reduced cytoplasm in the tumor cells is observed (×400). (c) AC case 2: cytoplasmic abundance and eosinophilia of the tumor cells are more prominent than those of IPLC (×400). (d) AM case 3: the cytoplasmic abundance and eosinophilia of the constituent cells are conspicuous but the nuclei are less atypical than those of IPLC and AC (×400). IPLC: invasive pleomorphic lobular carcinoma; cILC: classic invasive lobular carcinoma; AC: apocrine carcinoma; AM: apocrine metaplasia.</div>
