These lesions were also consistent with large-cell calcifying Sertoli cell tumor (LCCSCT). Indeed, the pathology specimens re-evaluated in our institution were diagnosed as LCCSCT (Fig. 2, Fig. 3). Fig. 1. Longitudinal sonogram of the left testis shows multiple diffuse hyperechoic masses with acoustic shadowing. B

Anticonvulsant therapy in brain-tumor related epilepsy

Background. The lifetime risk of patients with brain tumors to have focal epileptic seizures is 10–100%; the risk depends on different histology. Specific guidelines for drug treatment of brain tumor-related seizures have not yet been established. Aim. This review addresses the special aspects of antiepileptic drug (AED) therapy in brain tumor-related epilepsy. Methods. We analyzed the literature up to December 2015. Results. Based on current evidence the management of tumor-related

Physical examination revealed a tumor located in the upper pole of the left testis, which was suspected of being malignant due to its significantly increased density and irregular contours. Blood levels of the following tumor markers were determined: alpha-fetoprotein, human chorionic gonadotropin and lactate dehydrogenase. No abnormalities were found in any of these tests.

Introduction Angiomyofibroblastoma (AMF) is a rare, slow-growing and usually asymptomatic benign mesenchymal tumor that pre-dominantly arises in the genital tract, vulva, perineum and pelvis in women, while angiomyofibroblastoma-like (AMF-like) tumors develop in the inguinal region, scrotum and perineum in men(1). They usually arise in the 5th–6th decade of life. This type of tumor is derived from perivascular stem cells and has capacity of lipoid and myofibroblastic differentiation. AMF-like

Decreased or absent expression of blood group antigens is well known to occur in acute leukemia. In some carcinomas, the malignant solid tumor cells have also been shown to lose normal blood group antigen expression. In both carcinoma and hematologic malignancies, these findings have been associated with a more aggressive behavior of the neoplasm.

About 80% of AMLs present as isolated entities(2), but they are also frequently associated with tuberous sclerosis complex (TSC)(3).

Known as checkpoint inhibitors, these drugs act to upregulate the cellular and humoral immune response to tumor antigens by inhibiting T-cell autoregulation.

Fine-needle versus core-needle biopsy – which one to choose in preoperative assessment of focal lesions in the breasts? Literature review

recommendations of the Polish Ultrasound Society and American College of Radiology, BIRADS 4 and 5 lesions should be evaluated histopathologically. Core-needle biopsy makes it possible to establish a final diagnosis more frequently than fine-needle biopsy, both in the case of benign and malignant lesions. It delivers more information about the nature of a tumor (mutation of HER-2, estrogen and progesterone receptors and Ki-67 index). Its limitations include: underestimation of invasion and failure to

Monitoring the response to neoadjuvant chemotherapy in patients with breast cancer using ultrasound scattering coefficient: A preliminary report

Introduction Neoadjuvant chemotherapy (NAC) was initially used in locally advanced breast cancer (LABC) and the inflammatory form of cancer to downstage locally inoperable disease. Currently, it is recommended for patients with Stage 3 and with early-stage disease with HER-2 (human epidermal growth factor receptors positive or triple-negative (TNBC) breast cancer(1,2). NAC reduces the tumor mass by inducing intracellular damage, which causes cell death and degeneration. Response to treatment

Intra-abdominal fat. Part III. Neoplasms lesions of the adipose tissue

epithelioid tumor at this site is mesothelioma. The last but not least group includes secondary malignant tumors without an adipocyte component located in intra-abdominal fat. This is the most numerous group with prevailing carcinoma foci. For each of these groups, the authors present ultrasound features of individual lesions and discuss their differential diagnosis. In the vast majority of cases, the material for cytological and histological analysis can be obtained during ultrasound-guided procedures

Standards for the assessment of salivary glands – an update

salivary gland parenchymal lesions at different stages of the disease. Pleomorphic adenomas are usually hypoechoic, well-defined and polycyclic in most cases. Warthin tumor usually presents as a hypoechoic, oval-shaped lesion with anechoic cystic spaces. Malignancies are characterized by blurred outlines, irregular shape, usually heterogeneous echogenicity and pathological neovascularization. The accompanying metastatic lesions are another indicator of malignancy, however, final diagnosis should be
