Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the digestive tract and are generally asymptomatic. A 39-year-old female patient was hospitalized in 2012 at Clinical Department of Internal Medicine, Sestre milosrdnice University Hospital Center, for a focal hypodense irregular circular lesion located in segment III of the left hepatic lobe, accidentally found by ultrasonography and verified by computed tomography. The findings were also verified with nuclear magnetic resonance and esophagogastroduodenoscopy. A biopsy sample of the lesion was analyzed by histologic and immunohistochemical methods and identified as GIST. The patient underwent surgical operation (tumor excision with terminoterminal anastomosis created between the second segment of duodenum and jejunum and resection of liver segment III). The histopathologic findings matched GIST with a high probability of relapse according to the localization, size, mitotic activity and Ki-67 values. Therefore, therapy with imatinib at a dose of 400 mg/day was administered. Three years after the operation, the patient is still in remission.

A prospective study, which lasted from September 2014 to October 2016, covered the subjects who were examined for various benign tumor changes on the skin. The examinees were divided into 2 groups. The first group A (92 examinees) was composed of the examinees who inhabited a rural area. The second group B (98 examinees) was consisted of examinees who lived in an urban environment. The analyzed examinees gravitate towards rural and urban areas of Banja Luka, Gradiska, Stanari, Prijedor and Teslic in Bosnia and Herzegovina. The aim of this study is to analyze the attitude of examinees from rural and urban areas towards skin tumors. Parameters that were used for comparison of results are: personal attitude to skin tumors and previous skin examinations. There was no statistically significant difference in terms of prejudices among the respondents: that there is no risk of skin cancer, if a person is not exposed to the sun, and/or if changes in the skin are innate, as well as in the number of examinees who said they were not afraid of a skin tumor. In group A the number of examinees that have no opinion about skin tumors is three times higher, while in group B the number of examinees who said that they had a phobia of skin cancer is three times higher. It turned out that regular self-examination of the skin in group A is performed only by 7 (7.6%) examinees, while in group B it is done by 21 (21.5%) examinees, which proved to be statistically significantly different. Occasionally skin examination by a specialist family doctor (and/or a dermatologist) has been performed by 3 (3.3%) examinees of group A and 10 (10.3%) from group B. 4 (4.1%) examinees from group B and no one from group A perform dermoscopic examination occasionally. It was found that regular dermoscopy inspections or skin examinations by a specialist family doctor and/or dermatologist have not been done by any examinees from both analyzed groups. Attitude toward skin tumors of group A is more leisurely (less responsible), so for that group there is a possibility of higher risk degree for late diagnosis of malignant skin tumors.

The prospective study, which took place from February 2011 to March 2014, included respondents who were sent for computerized dermoscopy because of non-melanocytic skin tumours. Respondents were divided into 2 groups. The first one, group A (45 respondents), consisted of respondents who had expressed concern about the observed changes in the skin and the desire for examination. The second one, group B (50 respondents) were respondents that did not come for examination due to changes on the skin, but for other reasons, so they had indirectly detected suspicious skin lesions. The aim of this study is to analyse the importance of early suspicion of non-melanocytic malignant skin tumours by specialists in primary and secondary health care. Parameters for comparison were respondents' subjective attitude of non-pigment skin lesions and dermoscopy and/or PH findings. It has been shown that changes in the skin that bleed are sometimes highly suspect of NMSC because group A had 5 such cases and NMSC was detected in 4 cases, and group B had 7 respondents with haemorrhage and there were 4 with NMSC. In group B, out of 12 respondents who said that they had found suspicious skin lesions caused by trauma, there were 8 NMSC, while in group A there were 3 cases, which is a statistically significant difference. In group B, out of 16 respondents who claimed that they had had suspicious skin changes dormant for years, NMSC has been proven in 3 cases, and in group A there was not NMSC which is also a statistically significant difference. It was confirmed that the claims of the respondents are unreliable and that all patients should be addressed to computer dermoscopy, in patients with visible changes that arise even a slightest suspicion of NMSC.
