Intraductal histiocytes as a simulant of intraductal carcinoma of the prostate

Key Points

• To investigate the potential of histiocytes to mimic intraductal carcinoma of the prostate and the implications for diagnosis.
• Examined aggregates of histiocytes within prostatic ducts.
• Analyzed the appearance and characteristics of histiocytes in relation to IDC-P.
• Emphasized the role of immunohistochemistry in differential diagnosis.
• Histiocyte aggregates appeared solid and extended across intact ducts.
• These aggregates may lead to misdiagnosis as intraductal carcinoma.
• The study highlights the importance of immunohistochemistry in ambiguous cases.
