Immunoglobulin G4 (IgG4)-Related Hypophysitis.

We report two different cases of IgG4-related hypophysitis. In the first case, a pituitary lesion was accompanied by lymphocytic meningitis possibly mimicking tuberculous meningitis. The second case was unassociated with involvement of other organs.

Histologic variants of primary focal segmental glomerulosclerosis: presentation and outcome.

Introduction: The clinical significance of histologic variants of primary focal segmental glomerulosclerosis (FSGS) remains unclear. With the aim to determine presentation and outcome of the variants of FSGS in a hispanic population, we studied our cases of this glomerulopathy.

Methods: In this retrospective study, all renal biopsies with FSGS (1998-2009), were classified according to the Columbia's classification.
