Ductal Carcinoma in situ (Med Power)

Ductal Carcinoma in situ (Med Power) • This is a medium power view of ductal carcinoma in situ (DCIS). • The black arrows point to the intact basement membrane surrounding the ducts and confining the neoplastic cells to the duct. • The blue arrows point to the profound nuclear atypia which can even be spotted from this power. • In this type of DCIS the duct is not filled with neoplastic cells but close attention to the cytologic detail of the lining cells reveals their abnormality.
