Platin‑based chemotherapy does not improve survival in patients with non‑metastatic resected typical carcinoid tumors.

Chemotherapy is controversial in non-metastatic typical carcinoid (TC) tumors. Therefore, it was aimed to evaluate the impact of platin-based chemotherapy on the survival of patients with lung TC. The medical records of patients who underwent surgical resection for non-metastatic TC from 2002 to 2020 at our institution were retrospectively reviewed.

Bronchial Carcinoid Tumors with Massive Osseous Metaplasia: A Case Report and Review of the Literature.

Bronchial carcinoid tumors are primary lung neoplasms thought to originate from neuroendocrine cells, i.e. Kulchitsky cells, in the bronchial mucosa, although the type of cellular origin has not been clearly understood.

Intraoperative pathology consultation for pulmonary lesions: errors and deferrals.

The accuracy rate of frozen section constitutes an important step of quality assessment step in pathology practice. This study aimed to investigate pulmonary lesions that were incorrectly diagnosed or postponed for routine examination by pathologists at frozen section examination; it also aimed to discuss the reasons for difficult diagnoses and the various clues enabling the correct diagnosis to be made when such lesions are encountered. This study retrospectively reviewed the medical data of the thoracic surgery cases that underwent frozen section examination between 2009 and 2014.

Molecular markers for patients with thymic malignancies: not feasible at present?

Background: Thymomas and thymic carcinomas are rare malignancies and devising clinically effective molecular targeted therapies is a major clinical challenge. The aim of the study was to analyze BLC2 and vascular endothelial growth factor receptor (VEGFR) expression and KRAS and EGFR mutational status and to correlate them with the clinical characteristics of patients with thymomas and thymic carcinomas.

Materials And Methods: A total of 62 patients (mean age: 50.

The protective effect of ClinOleic against post-surgical adhesions.

Background: Although the English-language literature is full of studies about post-surgical adhesions, no definitive method has yet been identified to prevent them. The goal of this study was to investigate the effect of ClinOleic on reducing post-surgical adhesion formation.

Methods: Surgery was performed on 40 adult female Sprague-Dawley rats that were randomly assigned to receive either intraperitoneal ClinOleic, which was used to mimic chyle (ClinOleic group), soybean oil (soybean oil group), olive oil (olive oil group), or 0.

Why did the patient die? The relationship between ambulance accidents and death of patients: forensic medical issues.

This article's aim is investigating traumatic consequences of ambulance accident on patients and discussing difficulties to give a decision about the relation between death and accident at these cases. The cases were selected among the forensic medical reports concluded between 1996 and 2005 years. They were documented for age, sex, causes of urgent call, localization and extent of traumatic lesion, properties of events and board decisions.

Pulmonary alveolar microlithiasis in a textile worker.

Pulmonary alveolar microlithiasis is a rare lung disease characterized by small calculi, called calsispheritis, in the alveoli. The disease usually presents at age 20 to 30 years and is mostly diagnosed incidentally or detected on routine pulmonary roentgenograms. The radiologic findings are pathognomonic for the disease.

[Cardiac ruptures following myocardial infarction in medicolegal cases].

Objective: Characteristics of legal autopsy cases with cardiac rupture following myocardial infarction are investigated in this retrospective observational study and the results are compared with a control group consisting of acute myocardial infarction cases without rupture.

Methods: Legal autopsy reports of 50 cases with heart tamponade resulting from heart muscle rupture following myocardial infarction, autopsied at the Morgue Department of the Council of Forensic Medicine between the years 1998-2005 were retrospectively reviewed. Findings were compared to control group consisting of 30 myocardial infarction cases without rupture.

Expression of cyclooxygenase-2, c-kit, progesterone and estrogen receptors in uterine smooth muscle tumors: differential diagnosis.

We examined the expression pattern of cyclooxygenase-2 (COX-2) and c-kit in uterine smooth muscle neoplasms and tried to determine the role of these markers in differential diagnosis. Archival tissue from 64 patients with uterine smooth muscle neoplasms (20 leiomyomas (LMs), 22 atypical leiomyomas (ALMs), and 22 leiomyosarcomas (LMSs)) was immunostained with antibodies against estrogen (ER) and progesterone receptors (PR), COX-2 and c-kit. 7 of 20 LM cases and 5 of 22 ALM cases were immunopositive for COX-2, whereas none of the LMS cases stained immunopositive (p< or =0.

Cardiac myxoma: an unusual cause of sudden death in childhood.

Primary tumors of the heart and pericardium are rare in autopsy series. Considering all age groups, the most common cardiac tumor is the myxoma. They may arise in any of the four chambers or, rarely, on the heart valves.

Sudden death due to an unrecognized cardiac hydatid cyst: three medicolegal autopsy cases.

Echinococcosis is a human infection caused by the larval stage of Echinococcocus granulosus. The most common sites of infection are the liver and the lungs. Cardiac hydatid cysts are very rare, even in regions where hydatic cysts are endemic (the Mediterranean, South America, Africa, and Australia).

The accuracy of frozen section (intraoperative consultation) in the diagnosis of ovarian masses.

Objective: Frozen section is an important and helpful adjunct in the intraoperative diagnosis of ovarian tumors. This retrospective study was undertaken to determine the accuracy of frozen section diagnosis of ovarian masses and the reasons of discordance.

Methods: From January 1995 to December 2003, 1494 ovarian specimens were received for histopathological evaluation, and 617 of them were submitted for frozen section examination.

Lymphoepithelioma-like carcinoma of the breast: is it a distinct entity? Clinicopathological evaluation of two cases and review of the literature.

Lymphoepithelioma-like carcinomas (LELCs) are tumors with morphologic features identical to those of undifferentiated nasopharyngeal carcinoma. They are characterized by a pronounced lymphocytic infiltrate, often obscuring the neoplastic epithelial component. LELCs have been described in several organs, but are extremely rare in the breast.

Endometrial clear cell carcinoma metastatic to the paranasal sinuses: a case report and review of the literature.

Background: Paranasal sinus metastasis following endometrial carcinoma is extremely rare and a reflection of disseminated disease.

Case: We report a case of a 72-year-old woman who presented ethmoid and sphenoid sinus metastasis, 14 months after total abdominal hysterectomy and bilateral salpingo-oophorectomy due to an endometrial clear cell carcinoma.

Conclusion: One should recognize the possibility of a metastatic disease to the sinuses in patients presenting with associated symptoms.
