This article briefly reviews the life histories of five recent bloodthirsty leaders to discern shared features of their early childhoods and their cultures related to this trait. Three features of societies that foster transformation of widespread latent into manifest bloodthirstiness are noted. Two areas especially warranting further study are the contributions of genetic-organic factors and the relation of this trait to the power drive.

Inflammatory pseudotumor of the kidney with extensive metaplastic bone.

Inflammatory pseudotumor (IPT) of the kidney is a very rare lesion. We describe an 8-year-old boy with IPT of the kidney presenting as a single episode of hematuria. The case highlights a new feature, metaplastic bone, not previously described in IPT. This new feature may be helpful in establishing the correct preoperative and histopathologic diagnosis of IPT of kidney and avoiding inappropriately aggressive therapy. Despite its rarity, IPT of the kidney should be kept in mind in the differential diagnosis of a solitary renal mass.
