Background: Regarding the significance of abdominal masses in children, we aimed to identify the pathology of masses according to the age and sex groups. Materials and Methods: We retrospectively reviewed pathological reports of 461 patients with abdominal mass that underwent resection or biopsy during the study period (25 years). Results: One hundred and eighty six cases (40%) were non-neo...

The biology of pancreatic acinar cell cystadenomas has not been clearly defined. However, a non-neoplastic process, caused by a cell differentiation failure leading to a cystic transformation, has been discussed, as well as a benign neoplastic lesion. Pancreatic acinar cell cystadenomas usually consist of thin-walled unilocular or multilocular cysts, and mural nodules have been described in two...

CIS of the human cervix uteri is widely accepted as a preinvasive lesion that often progresses to invasive squamous carcinoma. Similarly, CIS is believed to arise by progression from cervical dysplasia, the earliest detectable neoplastic change in cervical epithelium (16). However, there is disagree ment as to how often there is progression from dysplasia to CIS and from CIS to invasive carcino...

background: malignant neoplastic lesions of the breast are one of the main causes of cancer death among women. several factors can be influential in the treatment process of breast cancer patients. the expression status of estrogen and progesterone receptors in tumor cells is among the most important determinants affecting the treatment approach and prognosis of these patients. in this paper, w...

cytomorphological changes of mitomycin c on urothelial cells may be misinterpreted as a neoplastic process. a 60-year old male patient who was given an eight-week course of intravesical mitomycin c due to non-invasive low grade transitional cell carcinoma. during his follow-up care, the findings of a urine cytology exam were as follows: nuclear enlargement of cells, wrinkled nuclear membranes, ...

Aim: Thyroid scan with sestamibi is used for evaluation of thyroid nodules with the aim of increasing specificity before surgery. In this study we evaluated the role of Sestamibi thyroid scan in candidates for thyroid surgery. Methods and patients: During two years, 37 patients were studied with solitary thyroid nodules, referred for thyroid surgery due to malignant or suspicious FNAB res...
