[Incidence and mortality due to cancer in Navarre, 1998-2002. Trends in the last 30 years]. / Incidencia y mortalidad por cáncer en Navarra, 1998-2002. Evolución en los últimos 30 años.

Between 1998-2002, 16,952 new cases of cancer were registered in Navarre. In men, the most frequently diagnosed cancers were in the following order: prostate, lung, colon and rectum, bladder and stomach, which accounted for 63.2%. In women, the sites were breast, colon and rectum, corpus uteri, stomach and ovary, which accounted for 57.6% of the cases. In the same period, 1998-2002, 4,127 men and 2,470 women died from cancer. Sixty percent of all deaths due to malign tumours in men were due to cancer of the lung, prostate, colon and rectum, stomach and bladder. In women this was due to cancers of colon and rectum, breast, stomach, pancreas and lung, which accounted for 49% of the cases. In men in Navarre there has been an increase in the incidence rates of cancer of the prostate, kidney and non-Hodgkin lymphoma. Avoidable cancers such as those related to smoking (lung, oral cavity and pharynx or pancreas) continue to rise, and represent a greater global risk of dying from cancer in the latest period studied than in the decades of the 1970s and 1980s. From 1995 up to the present, mortality due to cancer has moved from occupying the second place to become the first cause of death among men in Navarre. The global risk of death due to cancer in men is now equal to the first period studied, 1975-1977. Amongst women the global risk of death due to cancer fell by 25% between 1975 and 2002, basically at the cost of breast and stomach cancer. Tumours related to smoking increased both in mortality and in incidence and appear as a significant health problem amongst women in Navarre. Breast cancer has increased in incidence, with lower mortality figures than those of the first period 1975-1977. Invasive cancer of the cervix remains at very low rates in comparison with many European countries, including Spain. In both sexes colorectal and skin cancer has increased, while the incidence and mortality of stomach cancer continues to fall.

[Unavoidable epistaxis in the nasal infestation of leeches]. / Epistaxis debida a infestición nasal por sanguijuela.

An adult man is presented with a case of epistaxis due to leech (Limnatis linotica) intranasal parasitation. The geographical area where infection was performed is in the province of Teruel, northwest Spain. The only presented symptom was an incoercible nasal haemorrhage with low flow which didn't cease by anterior tamponade. 7 days after the process began he was heeded at the Emergency Service, Alcañiz Hospital, where the exam of left nasal fossa showed the presence of a olive-green long mass, very mobile. The treatment consisted on the leech extraction with a dissection forceps. Haemorrhage stopped immediately after the mild intervention and, reexamination the nasal fossa 15 days after, it was no wound or infectious complication observed. The patient was infested when drinking water from a fountain placed in rural area.

[Retroperitoneal lipoma (with areas of myxoid degeneration)]. / Lipoma retroperitoneal (con áreas de degeneración mixoide).

Retroperitoneal tumors of lipomatous origin are usually liposarcomas. Only a minority of adipose tumors of the retroperitoneum show histological criteria of benignity. We present the case of a 52-year-old woman, diagnosed of a retroperitoneal lipoma with areas of myxoid degeneration. The tumor involved the left kidney and was resected completely.
