Malignant melanoma of the urethra: a rare histologic subdivision of vulvar cancer with a poor prognosis
Malignant melanoma of the urethra is a rare tumour that is difficult to diagnose and treat, resulting in a poor prognosis. In this paper, we present the case of a 65-year-old woman who was referred to a gynaecologist because of a urethral mass that mimicked a caruncle. The tumour was removed by local excision, and a pathological analysis revealed a malignant melanoma. Distal urethrectomy was performed after three months with no evidence of residual tumour. There was no evidence of disease at a six-year followup. In this paper, we compare the epidemiology, treatment, staging, and prognosis of vulvar cancer in general to malignant melanoma of the vulva in particular
Disease, development, and defining indigenous identity : the emergence of machupo virus in post-revolutionary Bolivia
One of the four Latin American Hemorrhagic Fevers, Machupo virus, emerged in
1959 as a hemorrhagic disease in the lowlands of eastern Bolivia. The primary factor in
the emergence of Machupo virus into the human population was the development of the
eastern lowlands, brought about by Boliviaâs National Revolution in 1952. The
Movimiento Nacionalista Revolucionario (MNR) government encouraged mass
migration to eastern Bolivia in the form of resettlement programs in an attempt to
stimulate the development of agriculture. By 1959 when Machupo virus first emerged,
the MNR had distributed over 400,000 parcels of uncultivated land under the Agrarian
Reform Act. The resultant clearing of uncultivated lands by the indigenous population
was the primary factor in the emergence of Machupo virus.
The United States government, in response to the burgeoning communist threat in
the middle of the twentieth century, provided direction, technological assistance, and
economic aid in the colonization and development of Eastern Bolivia, the region endemic
to Machupo virus. Focus shifted from indigenous resettlement to immigration in order to
provide a population the West perceived as capable of successful agricultural
development. This shift was in response to the image of Indians provided for the West in
the accounts of nineteenth-century travel writers who explored the economic advantages
of the eastern lowlands. Travel writers ascribed an identity to the indigenous population
resulting in a status of less than second-class citizenship in the eyes of the West, limiting
them to subsistence agriculture, which contributed to the emergence of Machupo virus
