Epidemiological data indicate that the daily consumption of extra‑virgin olive oil (EVOO), a common dietary habit of the Mediterranean area, lowers the incidence of certain types of cancer, in particular bladder neoplasm. The aim of the present study was to evaluate the antiproliferative activity of polyphenols extracted from EVOO on bladder cancer (BCa), and to clarify the biological mechanisms that trigger cell death. Furthermore, we also evaluated the ability of low doses of extra‑virgin olive oil extract (EVOOE) to modulate the in vitro activity of paclitaxel or mitomycin, two antineoplastic drugs used in the management of different types of cancer...

An inflammatory myofibroblastic tumor (IMT) is a distinctive neoplasm composed of myofibroblastic and fibroblastic spindle cells, accompanied by inflammatory infiltration of plasma cells, lymphocytes, and eosinophils. IMTs rarely occur in the urinary bladder. It is important to distinguish this tumor from other malignant spindle cell tumors. Herein, we report a patient with an IMT showing muscle invasion, who underwent a transurethral resection of the bladder tumor and, at a later date, partial cystectomy. The resected tumor specimen revealed a proliferation of spindle-shaped cells on a background of plasma cells and lymphocytes...

Uterine fibroids are the most common uterine neoplasm of uterus and the female pelvis and the most common indication for hysterectomy worldwide. When the fibroid is large and fills the whole pelvis or is pedunculated, it becomes difficult to differentiate from ovarian mass clinically. Cervical fibroids pose enormous surgical difficulty by virtue of their relative inaccessibility and proximity to the anterior bladder, posterior rectum, and distorting the normal anatomical relationship of pelvic structures. A cervical fibroid especially with degenerative changes mimics an ovarian tumor and poses a clinical dilemma...

OBJECTIVES: Studies on alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) activity in the sera of patients with malignant neoplasms show that cancer cells in many organs may release ADH isoenzymes into the blood. The aim of this study was to investigate the differences in the activity of ADH isoenzymes and ALDH in the sera of patients with bladder cancer (BCa), and with different grades of the disease. MATERIAL AND METHODS: Blood samples were taken from 39 patients with BCa (15 patients with low-grade and 24 with high-grade BCa) and from 60 healthy subjects...

We describe a hernia of the swim bladder, with a concurrent mycotic granulomatous inflammation, and carcinoma of the swim bladder in a wild mullet (Mugil cephalus) referred for an exophytic dorsal mass. Grossly, the mass was white, soft, and composed of multiple cystic gas-containing chambers connected by a funnel-shaped tissue segment to the coelomic swim bladder. Histologically, the mass was characterized by cysts of variable size, multifocally contiguous with the subepithelial rete mirabile, supported by abundant fibrous tissue...

Diffuse large B cell lymphoma (DLBCL), currently the most common type of non-Hodgkin lymphoma (NHL), is an aggressive B cell neoplasm that typically presents in older adults as a rapidly enlarging mass. The enlarging mass typically represents a lymph node, although extranodal disease can occur in a significant percentage (40%) of cases. The most common extranodal sites of involvement include the gastrointestinal tract and skin; primary bladder lymphoma represents only 0.2% of extranodal non-Hodgkin lymphomas...

Primary gastric chorioadenocarcinoma (PGC) is a rare and rapidly invasive tumor. Choriocarcinoma is usually known to be of endometrial origin and gestational; however, it has been reported in other extragenital organs, such as the gall bladder, prostate, lung, liver, and the gastrointestinal tract. Human chorionic gonadotropin related neoplasms of the stomach are seldom discussed in the literature. We report a case of PGC in a 56-year-old man treated with a standard non-gestational choriocarcinoma chemotherapy regimen, EMA/CO (etoposide, methotrexate, actinomycin D, cyclophosphamide, vincristine), with a complete response and good tolerability...

a) Objective: An increase in cell-free DNA was observed in the plasma of many cancer patients. This major biomarker can be used to differentiate patients with malignant neoplasms from those with benign neoplasms or healthy patients. Depending on the characteristic of the tumor, there are qualitative variations in the circulating cell-free DNA. Today, studies on the concentration of fragments of circulating cell-free DNA and their respective sizes in patients with bladder cancer are not plentiful in the literature...

BACKGROUND: Inflammatory pseudotumour refers to a non-malignant tumour-like mass resulting from an inflammatory reaction that is composed of granulation tissue with leukocyte infiltration that commonly occurs in the paediatric or young adult population. These tumours occur more commonly in the lungs and the orbit but rarely does it affect the gastrointestinal tract. It poses a clinical diagnostic challenge since it is a benign condition than can mimic the malignant counterpart. Our case is a rare presentation of the caecal pseudotumour in the presence of a right undescended abdominal testis evaluated as a caecal tumour with a differential diagnosis of a testicular malignancy...

A 92-year-old man had noticed enlargement of a mass in the right scrotum and inguinal region for nine months. The patient was introduced to our department for right testicular tumor. Physical examination showed an over fist-sized, hard mass in the right scrotum. Magnetic resonance imaging (MRI) showed the mass, which consisted of fatty and solid contents. In addition, MRI revealed a bladder tumor simultaneously. Computed tomography revealed no distant metastases. The patient underwent right high orchiectomy with the mass resection and transurethral resection of the bladder tumor (TURBT)...

Advances in immunotherapy have changed the therapeutic landscape in many malignancies. Immune checkpoint inhibitors have already received regulatory approval in melanomas, lung, renal and bladder carcinomas. A common feature of these neoplasms is the increased mutational load, related to a possible increase number of tumor neoantigens that are recognized by the immune system. The mechanisms that DNA damage could confer to the mutational load and the formation of neoantigens and how this could be exploited to advance our immunotherapeutic strategies is discussed in this review...

Small cell neuroendocrine carcinoma (SNEC) is a rare form of malignancy. It mainly presents as bronchogenic neoplasm, and the extrapulmonary form accounts for only 0.1% to 0.4% of all cancers. These extrapulmonary tumors have been described most frequently in the urinary bladder, prostate, esophagus, stomach, colon and rectum, gall bladder, head and neck, cervix, and skin. Primary SNEC of the sinonasal tract is extremely rare with only less than 100 cases reported in the literature. Because of extreme rarity and aggressiveness of the tumor, the management for this entity varies considerably mandating multimodality approach...

BACKGROUND Radiotherapy is explicitly indicated as one of the excluding factors in diagnosing overactive bladder syndrome (OAB). Nevertheless, symptoms of OAB such as urgent episodes, incontinence, pollakiuria, and nocturia, which are consequences of irradiation, led us to test the effectiveness of VESIcare®/Solifenacin in patients demonstrating these symptoms after radiation therapy of small pelvis organs due to malignant neoplasm. MATERIAL AND METHODS We conducted an observatory clinical study including 300 consecutive patients with symptoms of post-irradiation bladder; 271 of those patients completed the study...

The expression status of ZKSCAN3, a zinc-finger transcription factor containing KRAB and SCAN domains, as well as its biological significance, in human bladder cancer remains largely unknown. In the current study, we aimed to determine the functional role of ZKSCAN3 in bladder cancer progression. Immunohistochemistry in tissue specimens detected ZKSCAN3 signals in 138 (93.2%) of 148 urothelial neoplasms, which was significantly higher than in non-neoplastic urothelial tissues [76 (84.4%) of 90; P=0.044]. Correspondingly, the levels of ZKSCAN3 gene were significantly elevated in bladder tumors, compared with those in adjacent normal-appearing bladder mucosae (P=0...

Hepatobiliary cystadenomas are mucinous cystic neoplasms arising in the liver, extrahepatic bile ducts or gall bladder. Extrahepatic cystadenomas are rare neoplasms requiring complete excision as there is a chance for recurrence and malignant transformation. Angiomyolipoma (AML) belongs to the perivascular epithelioid cell group of neoplasms, and kidney is the commonest site involved. We report a case of an unusual combination of extrahepatic biliary cystadenoma with angiomyolipoma in an adult female without evidence of tuberous sclerosis...

BACKGROUND: Autoantibodies against N-terminal domains and linker subdomains of envoplakin (EVPL) and periplakin (PPL) were frequently detected in sera of paraneoplastic pemphigus(PNP) patients. OBJECTIVES: To further investigate finer epitopes of EVPL and PPL, and evaluate their associations with clinical aspects of PNP. METHODS: We produced 12 overlapping truncated fragments of these regions in Escherichia coli, and measured their reactivities to sera of 65 PNP patients and 50 healthy volunteers by enzyme-linked immunosorbent assays (ELISA)...

Malignant priapism secondary to penile metastases is a rare condition. This term was originally used by Peacock in 1938 to describe a condition of painful induration and erection of the penis due to metastatic infiltration by a neoplasm. In the current literature there are 512 case reports. The primary tumor sites are bladder, prostate and rectum. The treatment has only palliative intent and consists of local tumor excision, penectomy, radiotherapy and chemotherapy. We present one case of malignant priapism originated from prostate cancer, and two from urothelial carcinoma of the bladder...
