DX：Poorly differentiated ductal carcinoma。
They are composed of a mixture of densely packed, small irregular glands as well as solid tumour cell sheets and nests, which entirely replace the acinar tissue. While typical large, duct-like structures and intraductal tumour components are absent, there may be small squamoid, spindle cell, or anaplastic foci (comprising by definition less than 20% of the tumour tissue). There may be some scattered inflammatory cells. Foci of necrosis and haemorrhage occur. The neoplastic cells show marked pleomorphism, little or no mucin production, and brisk mitotic activity. At the advancing edge of the carcinoma, the gland and the peripancreatic tissue are infiltrated by small clusters of neoplastic cells.
