RESUMEN
Acute appendicitis with its characteristic clinical course is one of the most common diagnoses that require urgent surgery. The following three case reports present patients with symptoms typical of acute appendicitis which was, however, not confirmed intraoperatively. Preoperative CT or MRI were not requested because symptoms clearly indicated acute appendicitis. The first case describes a male patient with right-sided diverticulitis, the second case report involves a pregnant woman in 33rd week of gestation with right adnexal torsion due to a dermoid cyst, and in the last report, a case of spontaneous perforation of appendiceal mucinous neoplasm is presented.Key words: right-sided diverticulitis - dermoid cyst - adnexal torsion - mucinous neoplasm - pseudomyxoma peritonei - appendicitis.

Recent knowledge on vitamin D has shown that its active form not only regulates calcium and phosphate metabolism but also has significant antimitotic and cell differentiation effects. It can inhibit proliferation, angiogenesis and metastatic potential in cancer tissue. Insufficient vitamin D plasma levels are found in 20-â60% of cancer patients at dia-gnosis. By many authors, vitamin D deficiency is associated with higher aggressivity of tumor and shorter survival of patients. Even in the absence of clinical studies showing benefit of supplementation on outcome, clear recommendations are currently available for treatment of vitamin D deficiency. Owing to the high prevalence of vitamin D insufficiency in cancer patients and significant risks of its further decrease after antitumor therapy, it should become standard of care to examine 25-âhydroxyvitamin D serum levels and correct vitamin D insufficiency in cancer patients.
