Pachydermodactyly: a case report and discussion of the pathologic entity.

Numerous case reports have described idiopathic hypertrophy of the skin on the dorsum of the hands. Many different and confusing names have been assigned to these conditions. A case report of a patient with pachydermodactyly is presented, with a discussion of the literature, in an effort to clarify the identification, treatment, and nomenclature of idiopathic hyperkeratosis and acanthosis of the dorsum of the hands.

Light-microscopic analysis of sectioned Sézary cells: an accurate alternative to electron microscopy.

The prognostic implications of circulating Sézary cells in mycosis fungoides (MF) are not known, and the significance of fluctuating Sézary cell counts in either MF or the Sézary syndrome has not been assessed. Such studies have been hampered by the inaccuracy of counts performed on routine blood smears and the unavailability of electron microscopy for routine purposes. The present studies conducted on the peripheral blood of 35 patients with either MF or the Sézary syndrome show that Sézary cell counts performed by light microscopy of sectioned Epon-embedded lymphocyte fractions are as accurate as those carried out at the ultrastructural level.

Hydrops fetalis, hydramnios and hepatic vascular malformation associated with cutaneous hemangioma and chorioangioma.

A premature baby presented with severe hydrops fetalis due to a multifocal angiomatous malformation of the liver. There were two other small vascular tumors: hemangioma of the skin and chorioangioma. Hydramnios and placental edema were also present.
