All two cases were diagnosed as myeloma-like cast nephropathy. In HIV positive patients biopsy finding confirmed HIV associated changes in addition to myeloma-like cast nephropathy.
Renal needle biopsy was done showing conventional HIV associated nephropathy with coexisting myeloma-like cast nephropathy. Light microscopy revealed foci of tubular cystic dilatation and diffuse tubular dilatation containing eosinophilic, Periodic Acid-Schiff (PAS) negative casts coupled with segmental collapse of capillary tufts and focal glomerulosclerosis.
The pathologic consequence is hemoglobin cast nephropathy which in our case led to acute renal failure and death.

Comparison of the percentage of light chain cast nephropathy cases (33% of all cases associated with plasma cell dyscrasia) with proximal tubular-centered cases (roughly 46% of all cases with underlying plasma cell dyscrasias) emphasizes that the total number of proximal tubulopathies indeed represents a very significant portion of all lesions observed.

The measurement of serum concentration of the clonal FLCs and that of urine level of albumin may be considered the landmarks for screening algorithms in patients with cast nephropathy [69].
In this study, FLC levels were not measured, and histologic evidence of cast nephropathy was insufficient.
The most common cause of renal insufficiency in patients with multiple myeloma, occurring in approximately 30% of patients, is cast nephropathy. (Leung, 2008).
(5-11) There are some morphologic patterns that are readily recognizable at the light microscopic level, especially when the manifestations are florid, including that of myeloma cast nephropathy, nodular glomerulosclerosis associated with light or heavy chain deposition disease, and light and heavy chain (AL and AH) amyloidosis.
