The authors report their experience on diagnosis of maxillo-facial Burkitt's lymphoma using needle aspiration and cytology. In all the 21 patients presenting a histological proved Burkitt's lymphoma, the diagnosis was done before with cytology. This method has a 100% sensibility. Thus, cytologic diagnosis of maxillo-facial Burkitt's lymphoma is very reliable. In tropical areas with little revenues and where Burkitt's lymphoma is frequent, needle aspiration and cytology need to be well known and used.

We reviewed 119 renal biopsies performed between 1964 and 1982 on adults aged 60 or more. The two main indications wer: renal failure (35/119) and nephrotic syndrome (35/119). Histology showed: primary glomerular diseases (76/119), systemic diseases with renal involvement (31/119), arteriosclerosis only (5/19), tubulo-interstitial nephritis only (5/119). No obvious lesion was seen in 2 cases. Additional arteriosclerosis was observed in 21 cases and additional tubulo-interstitial nephritis in 6 cases. Primary glomerular diseases consisted mainly in diffuse membranous glomerulonephritis (18/76). Systemic Lupus Erythematosus (7/31) and amyloidosis (6/31) represented most of the systemic diseases with renal involvement. The usefulness of renal biopsy in diagnosis, treatment and prognosis of a wide variety of renal diseases in elderly adults is demonstrated.
