[Neonatal cholestasis: the viewpoint of the pathologist].
No full textThe authors make a review of paediatric-neonatal cholestasis, a troublesome field in clinical and hepatopathology. They focus the main topics and stress the differential aspects in extrahepatic biliary atresia, "neonatal hepatitis", cholestatic syndromes associated with paucity of interlobular biliary ducts and metabolic diseases. The "overlap" areas and differential diagnosis in these chapters are a challenge for the pathologist. The importance of a close collaboration with clinicians is stressed

Primary laryngeal malignant fibrous histiocytoma: a case report.
No full textMalignant fibrous histiocytoma (MFH) of the upper respiratory tract is rare. We report a case of laryngeal MFH in a 78-year-old man. The patient died 8 months after the first surgical treatment. The clinicopathologic features are described, and the importance of electron microscopy and immunohistochemical techniques in the differential diagnosis with so-called "sarcomatoid carcinoma" is stressed. The tumor has an aggressive biological behavior and tends to recur and metastasize
Blue nevus of the uterine cervix.
No full textA case of blue naevus of the endocervix is reported with immunohistochemical and ultrastructural findings. The dendritic melanin-containing cells are analogous to the blue naevi cells of the skin. Electron microscopy showed melanosomes in dendritic cells but no cells with melanin-producing Schwann cells features were observed. Histogenetic hypotheses are discussed
