title: Attending rounds: an older patient with nephrotic syndrome.
abstract: Nephrotic syndrome in older adult patients is a common clinical conundrum. Membranous nephropathy (MN) is a lesion frequently found to underlie the nephrotic state in such patients. Determining with reasonable certainty whether the nephrotic syndrome and MN is primary (idiopathic) or due to an underlying disease such as neoplasia can be a daunting clinical challenge. By way of a presentation of an illustrative case and a focused review of the relevant literature, the approach to evaluation of such patients, with an emphasis on the putative causative role of neoplasia in MN, is analyzed and a potential contemporary pathway for acquiring the correct diagnosis is offered.
