Cubanichthys cubensis , the Cuban killifish , is a species of killifish from the family Cyprinodontidae , the pupfishes which is endemic to Cuba. Cubanichthys cubensis has a cylindrical body which is slightly broader and taller in the anterior portion. They are a typical size for kiilifish, the males are 3. They are not colourful, the body being a mottled semi-transparent golden buff with a creamy white patch which starts behind the gill covers and forms an diagonal arch which reaches the anal fin and which covers the viscera. A series of horizontal light blue lines start at the gill covers and extend along the body to the caudal peduncle. There is a broken dark line which frequently runs from the lower mandible through the middle of the eye, and proceeding to the upper part of the gill cover.

In this population, anal cancer is one of the most common non-AIDS-defining malignancies. A cross-sectional study to detect anal lesions and HPV infection was performed. Anal mucosa samples were collected from 56 HIV-infected men from Cuba. The cytological diagnosis was done according to Bethesda System. This information may be of importance for local decision makers to improve prevention strategies, including the introduction of HPV vaccine in Cuba. While anal carcinoma is rare in the general population [ 1 ], it is one of the most common non-AIDS-defining malignancies in the era of combination antiretroviral therapy [ 2 ]. It is more frequent among individuals with human immunodeficiency virus HIV infection, particularly in men who have sex with men MSM [ 3 ].
