Our data provide the first complete picture of the epidemiology of scabies in rural Egypt. The epidemiologic characteristics of the disease should be considered in the design of disease control programs for other villages with scabies epidemics. Our findings revealed that good control was achieved with the following: increased awareness and better case finding, education of the staff at the rural health unit, improved hygiene measures, and massive treatment campaigns using effective drugs such as topical permethrin and oral ivermectin.

Our study provides the first picture of the epidemiology of leprosy in a high-prevalence village in rural Egypt. Leprosy detection campaigns should be initiated and directed towards high-prevalence villages. Provision of leprosy control activities in rural health units is necessary in order to detect new cases. The risk for leprosy is associated with HLA-DR2 and -DQ1 markers, and these markers appear to increase personal susceptibility to leprosy in this village.

PRIMARY bronchiolo-alveolar adenocarcinoma is rare in domestic animals. It has been observed in cattle (Charan and others 1996), buffalo (Charan and Iyer 1978/79), dogs and cats (Walzi and Hunyady 1967, Stunzi and others 1974, Bostock and Owen 1975), but appears not to have been reported in camels. The following communication describes a spontaneously occurring primary bronchiolo-alveolar adenocarcinoma in a dromedary camel (Camelus dromedarius) in Saudi Arabia. During routine meat inspection of camels slaughtered at Al-Ahsa abattoir in the eastern region of Saudi Arabia, one female camel of a local breed, about 12 years old, exhibited multiple welldefined pale yellowish grey spherical masses of various sizes in both lungs. These were seen projecting from the lung surface or embedded in the lung tissue and measured between 1 and 10 cm across. The consistency was rather frail and the cut surface had a smooth appearance (Fig 1). The bronchial lymph nodes were
