La presencia del melanoma maligno cutáneo en felinos exóticos está pobremente reportada. Una hembra de tigre de Bengala blanca (Panthera tigris tigris), de 6 años, no castrada, solitaria y viviendo en un ambiente adecuado, fue evaluada por la presencia de una masa cerca del ojo izquierdo. La histopatología de la biopsia remitida mostró la presencia de melanocitos con características anaplásicas (pleomorfismo, citomegalia, cariomegalia, binucleación), área hemorrágica y foco inflamatorio fibrinoso. El diagnóstico histopatológico fue melanoma maligno. Dos meses después del diagnóstico, la tigresa manifestó un deterioro considerable con pérdida de peso y presencia de una masa redonda en el cuello. En aquel momento, por su tamaño, el melanoma obstruía totalmente la visión. Con base en esto, y por razones humanitarias, el animal fue eutanasiado. Al momento de la necropsia, se observó metástasis en pulmones, pleura y riñones. Este caso evidencia la importancia de dar a conocer la presentación de melanomas en especies poco reportadas.

Indirect Evidences of Wildlife Activities in Shoals of Western Ghats, a Biodiversity HotspotsThe presence of wildlife fauna and its activities were ascertained with the density of the scat, dung and other markings or droppings of the wildlife abode therein. Attempt was made to find out spatial differences in the activities of the wildlife populations and to comment on the abundance of different preys and predators within shola forests of Western Ghat hill forests, a Biodiversity hotspot in India. An indirect sampling method, Transect Count Method, was employed to count dung/pellet group/scat and other markings in that area. Pachyderms were found to be mostly dominant in Varagaliar and Punnumala shola patches while scats of all the three important predators, viz., tiger (Panthera tigris tigris), Indian wild dog (Cuon alpinus) and leopard (Panthera pardus) were encountered only in Varagaliar shola. Greater abundance was recorded from Indira Gandhi Wildlife Sanctuary than Silent Valley National Park may be because of the restriction of animal movements in the former due to topographical barriers and its existence as isolated shola patches that led to a greater concentration of wild fauna in a relatively segregated forest cover.
