Aim: It was aimed to investigate the relationship of disease clinical stage between the maximum diameter of primer lesion (MDPL), maximum of standardized uptake value (SUVmax), mean of standardized uptake value (SUVmean), metabolic tumor volume (MTV) and total lesion glycolysis (TLG) values derived from positron emission tomography/computed tomography (PET/CT). Patients and Methods: Lung cancer patients diagnosed histopathologically between 01.01.2012 and 31.12.2014 in Necmettin Erbakan University Nuclear Medicine Department of Meram Medical Faculty scanned for PET/CT for lung cancer diagnosis and staging, were included in this study. MDPL, SUVmax, SUVmean, TLG and MTV derived from PET-CT scanning and their histopathological subtypes, other clinical and radyological information of patients were noted. The non-small cell lung cancer (NSLC) were graded according to tumor diameter, nodal and involvement metastasis (TNM) staging system. The small cell lung carcinoma (SCLC) diagnosed were categorised as limited or extensive stage. Results: In this study, the mean age of 118 men and 12 women, totally 130 patients, was evaluated 63,46 ±9,96. The patients were classified as 106 NSCLC (81.5%) ve 24 SCLC (18.5%). The histopathologically diagnosed NSCLC patients were consists of 62 squamous cell cancers, 39 adeno cancers, and 5 other subtypes. It was observed that there was no significant relationship between the MDPL, SUVmax, SUVmean, MTV and TLG values among SCLC. Additionally, it was also found that there was no correlation between these parameters with the SCLC stage. MDPL, SUVmax, SUVmean, MTV and TLG parameters were related with stage in NSCLC patients. Conclusion: Higher SUVmax, SUVmean, MTV, and TLG values of the primary tumor were predicting the more advanced clinical stage in NSCLC. [ABSTRACT FROM AUTHOR]

In this study we reviewed 7 neuroendocrine tumors of bladder among 690 bladder carcinomas with their clinicopathologic characteristics diagnosed in Antalya region, in two medical centers. In each case, the following clinical data were recorded: age, sex, presenting symptoms, location of the tumor, clinical staging, treatment, follow-up and outcome. This study indicates that neuroendocrine carcinoma of the urinary bladder is as aggressive as its pulmonary counterpart and the overall prognosis of this tumor is very poor.

Small Cell Carcinoma of the bladder accounts for less than 1% of all bladder tumors. Small Cell Carcinoma of the bladder has an aggressive behaviour and is usually metastatic at diagnosis. Due to its infrequent occurence, the literature on this entity is limited; which unsurprisingly leads to an uncertanity in defining an ideal therapeutic approach. This report, overviews the literature while describing a 70- year- old female patient who is diagnosed with small cell carcinoma of the bladder arising in an unusual localization.

Mesanenin küçük hücreli karsinomu, tüm mesane tümörleri içinde 1% den az sıklıkta izlenir. Agresif davranışından dolayı tanı konulduğunda sıklıkla metastaz yapmıştır. Nadir görülmesi nedeniyle az sayıda literatür bilgisi vardır. Bu durum ideal tedavide belirsizliğe neden olmaktadır. Bu olguda mesane tavanında yerleşim gösteren, mesanenin küçük hücreli karsinomu tanısı alan 70 yaşındaki kadın hasta literatür eşliğinde sunuldu.

Neuroendocrine tumors (NETs) are a heterogeneous group of tumoral lesions originating from diffuse endocrine system cells. They occur mostly in the gastrointestinal system and the lung. Primary NETs of the female reproductive tract are rare. In a widely used classification, primary small cell neuroendocrine carcinomas (SCNECs) and large cell neuroendocrine carcinomas (LCNECs) of the endometrium were included in a subgroup of poorly differentiated neuroendocrine carcinomas. SCNECs of the endometrium are very rare and they are often combined with other epithelial neoplasms. Their myometrial and extrauterine invasions are common during the initial diagnosis due to their aggressive behaviors. In this article, we present a rare case of primary endometrial SCNEC detected within the benign endometrial polyp and without invasion of myometrium and extrauterine tissues in a 70-year-old female patient presenting with postmenopausal bleeding. Histopathologically, the tumor cells showed positive staining with Synaptophysin, the Ki-67 labeling index was 80-90%, the mitotic index was 15/10 per HPF and there was no necrosis and lymphovascular invasion.

Merkel cell carcinoma, also known as small cell carcinoma of the skin, is a malignant cutaneous neuroendocrin tumor. The diagnosis of this tumor is rare but it has high tendency for local recurrence, regional lymph node and distant metastases and also has a high mortality rate. For these reasons, immunohistochemical studies are necessary for making a definitive diagnosis and also for excluding a diagnosis. In this publication, we discuss a case of mixed Merkel cell carcinoma and squamous cell carcinoma in the context of the contemporary literature. [ABSTRACT FROM AUTHOR]

Small cell carcinoma of the bladder isa rare entity characterized clinically by an aggressive behavior with a high incidence of systemic metastases. The frequency of small cell carcinomas in the urinary bladder is 0.5% of all bladder tumors. We present a case of a small cell carcinoma of the bladder in a 48-year-old man and a review of the literature. [ABSTRACT FROM AUTHOR]
