[Prostate leiomyosarcoma with perineal exophytic mass]. / Leiomiosarcoma prostático con masa exofítica perineal.

Report on one case of prostate leiomyosarcoma, an infrequent and usually highly aggressive urologic neoplasia. Emphasis on the imaging and pathoanatomical diagnosis, highlighting the high value of the later as immunohistochemistry is usually essential to establish its nature. Choice treatment is oncologically radical surgery. Quite often this is impossible to carry out and so chemo- and radiotherapy schedules are commonly associated as neoadjuvant, adjuvant or palliative therapies. The reported case showed aggressive evolution unresponsive to management. Also, during the condition development a rare complication such as occurrence of an exophytic tumoral mass in the perineum appeared.

[Eosinophilic cholecystitis associated with rupture of hepatic hydatid cyst of the bile ducts]. / Colecistitis eosinofílica asociada a ruptura de un quiste hidatídico hepático en vías biliares.

Eosinophilic cholecystitis is a rare finding characterized by an inflammatory infiltrate composed primarily of eosinophils. We report a case of eosinophilic cholecystitis associated with hepatic hydatic cyst ruptured into the biliary tract. The release of hydatid cyst content into the biliary tract may have induced a hypersensitivity reaction with numerous eosinophils in the gallbladder wall.

[Incidence of digestive system neoplasms. Trends. Soria 1981-1990]. / Incidencia neoplásica de aparato digestivo. Tendencias. Soria 1981-1990.

The aim of this study was to evaluate, to compare and to identify the various incidence rate trends in digestive tract malignant tumours in the province of Soria. Tumor sites and histological types, patient's age, sex and town and area residence were studied. All new cases of digestive tract malignant tumours were collected during the 1981-1990 period. 30.4% of all malignant tumours in men (1906 patients) and 29% in women (1,256 patients) came from digestive tract sites. Incidence rates for each site were calculated for the two 1981-1985 and 1986-1990 subperiods. The histology, rates and trends of the tumours were compared with the other national and international cancer registries. Gastric cancer showed the highest adjusted rate for men (35.1 x 10(5) and colo-rectal cancer one for women (14.7 x 10(5). The lowest rates were for men in the gallbladder (0.5) and liver (1.1) sites; and for women in the gallbladder (1.6), whose diminishing trend was significant (2.92/0.75) (p < 0.05) and liver (0.5). Colorectal cancer showed a marked increase between the two subperiods for both sexes (men: 13.1/27.6) (women: 9.8/19.2). Pancreas cancer trends ascended for both sexes (men: 1.22/2.74) (women: 0.13/1.46). Gastric cancer rates in Soria are higher than the rest of the cancer registries in Spain while gallbladder, liver, and colorectal, cancer rates are one of the lowest for both sexes. Trends are significantly increasing in colorectal sites for both sexes (p < 0.01), and for women only in the pancreas (p < 0.05). The other cancer rate sites showed lesser variations and are not statistically significant.

[Nasal hemangiopericytoma]. / Hemangiopericitoma nasal.

We are submitting a case of haemangiopericytoma of the nasal fossae, diagnosed and treated in our department. This is the second case we have seen as the first one was published by J. Marin and al. (1) in 1979. The patient in question is male, 35 years of age, who suffered from a tumour in the nasal partition, in the left nasal fossa and which made itself evident through repetitious epistaxis. The tumour was removed and there has not, so far, been any relapse. We have carried out a study of the available literature concerning haemangiopericytomas located in the nasal fossae and in the paranasal sinuses and come across 50 cases. In 1987 Chawla compiled 23 cases (2). Of the 50 cases, only 6 are described as being located in the nasal wall. We are submitting a list of all the cases that we have published and gathered with the age and sex of each patient and year of their publication.
