Verruga peruana is a vascular hyperplasia that is sometimes histologically mistaken for a malignant neoplasm. An infiltrative pattern with nuclear pleomorphism and mitoses is prominent in some lesions. From a series of lesions of verruga peruana, we selected five atypical lesions, two of them closely resembling epithelioid angiosarcoma. We used histologic criteria as well as morphometry and flow cytometry to further characterize the atypical features of the lesions. Histology and morphometry evidenced marked nuclear pleomorphism. Flow cytometry failed to reveal aneuploidy and disclosed about 10% of the cells to be in the S, G2 and M phase.
The history of human Bartonellosis, a unique South American biphasic bacterial disease, is reviewed. The course of this disease and its natural history offer many puzzling problems. Its geographic distribution, its absence of a natural reservoir, the development of transient immunosuppression during the acute hematic phase, and the subsequent development of vascular proliferations are highlighted. These vascular proliferations represent a unique example of tissue reactivity recalling the vascular proliferations of patients with AIDS. In addition, the authors review the life and times of Daniel Alcides Carrión, a Peruvian medical student who in 1885 by self-experimentation linked both phases of the disease and died in doing so. Carrión's life, and the impact of his experiment on the subsequent study of Bartonellosis by Peruvian and international scholars, epitomize the constant struggle of the Peruvian medical profession (past and present) to upgrade domestic biomedical research and to find a national identity.
A written account implicating Phlebotomus sand flies as vectors of Carrion's disease and cutaneous leishmaniasis in Peru was published by Cosme Bueno in 1764. Bueno's report precedes other publications implicating sand flies in the transmission of human pathogens by nearly a century and a half.
