Progressive multifocal leukoencephalopathy and idiopathic CD4+lymphocytopenia: a case report and review of reported cases.

Progressive multifocal leukoencephalopathy (PML) is a well recognized demyelinating neurological disorder caused by JC virus. Idiopathic CD4(+) lymphocytopenia (ICL) is a syndrome first described by the Centers for Disease Control and Prevention as a CD4(+) count <300 cells/mm(3) or a CD4(+) count that is <20% of the total T cell count on 2 occasions, with no evidence of human immunodeficiency virus (HIV) infection on testing, and absence of any defined immunodeficiency or therapy that depresses the levels of CD4(+) T cells. To the best of our knowledge, this is the third reported case of PML and ICL, and also the first reported case of the use of cidofovir to treat PML in a patient not infected with human immunodeficiency virus.

An unusual case of ocular involvement in primary systemic nonfamilial amyloidosis.

A case of primary amyloidosis with vitreous involvement was diagnosed by study of a specimen obtained by pars plana vitrectomy. Vitreous opacities had been interpreted clinically as a vitreous hemorrhage. Medical evaluation after study of the vitreous specimen failed to demonstrate evidence of amyloidosis, although postmortem examination 19 months later established the systemic diagnosis of nonfamilial systemic primary amyloidosis. Both eyes were obtained postmortem. Amyloid involvement of the vitreous, retina, and choroid was found. There was also amyloid deposition in the trabecular meshwork, although the intraocular pressure was normal. Amyloid was deposited along the anterior, pupillary, and posterior surfaces of the iris. The histochemistry, ultrastructure, and treatment of this condition are discussed.
