Placental mesenchymal dysplasia.

abstract：CONTEXT:Cytologic features of low-grade neuroendocrine carcinoma are well described in primary sites. There are fewer reports of the cytologic features specific to metastatic liver lesions or the frequency of misdiagnosis. OBJECTIVE:To identify discriminating cytologic features and characterize the rate of misdiagnosi...
