Background: Uterine carcinosarcomas (UCS) constitute 3-4% of all uterine malignancies and 16% of deaths caused due to uterine neoplasms.

Aim: In this study, we aimed to perform DNA-based mutation analysis in 12 genes (KRAS, NRAS, EGFR, C-KIT, BRAF, PDGFRA, ALK, ERBB2, ERBB3, ESR1, RAF1, PIK3CA) to determine the molecular subtypes of UCS using next-generation sequencing (NGS) in patients with aggressive UCS and poor prognosis. We aimed to compare the results of our analysis with clinicopathological data to contribute to the development of targeted therapy approaches related to the molecular changes of UCS.

Article Synopsis
  • - The study explored the clinical and prognostic features of acral metastases in 46 patients, focusing on their treatments and how those treatments affected survival rates, using data from patients treated between 2015 and 2019.
  • - It included 64 acral metastatic lesions, primarily affecting the lower extremities (75%), with most originating from lung adenocarcinomas, and pain being the most reported symptom.
  • - Treatment methods varied and were categorized into surgical (either excisional or palliative) and non-surgical options, but no significant link was found between primary tumor type and the timing of acral metastasis diagnosis.

Postinfectious glomerulonephritis (PIGN) is an immune-mediated glomerulonephritis caused by bacterial infections. Treatment of PIGN includes appropriate treatment of underlying infection and supportive treatment of the nephritic syndrome. Immunosuppressive drugs may be used to treat PIGN who have a renal failure with or without crescents and suggested only to the patients who does not have an active infection.

Malignant mesothelioma of the tunica vaginalis testis (MMTVT) is an extremely rare tumour, usually mimicking benign pathologies of the scrotum. Our case is an 84-year-old male patient who appealed with a painless, left-sided scrotal swelling longer than 2 months. Although the level of tumour markers was normal, ultrasonographic examination results forced us to perform an inguinal scrotal exploration.

Background: Many children with kidney diseases can be diagnosed and treated without a biopsy. However, biopsy is a valuable method for the diagnostic and prognostic evaluation of children with kidney diseases.

Aims: To evaluate the clinical and pathological profiles of the kidney biopsies in our department to provide epidemiological data for clinical practice.

Purpose: The aim of this study was to evaluate the importance of Ki-67 in Human Epidermal Growth Factor Receptor 2 (Her-2) positive breast cancer patients.

Methods: We reviewed the records of patients diagnosed with Her-2-positive non-metastatic breast cancer between 2005 and 2011. Paraffin-embedded tissue samples were stained with MIB-1 mouse monoclonal antibody to find Ki-67 levels.

Article Synopsis
  • Hematoma is a significant factor in graft loss, and this study examined how microporous polysaccharide hemospheres (MPH) affect graft survival and associated neutrophil levels.
  • In a rat model, the MPH group demonstrated a significantly higher graft survival rate (97.86%) compared to control and saline groups, indicating that MPH positively impacts graft survival.
  • The study found that neutrophil counts were highest in the hematoma group, with MPH reducing neutrophil levels, suggesting that increased neutrophils correlate with lower graft survival.

Cervicovaginal smear screening is well known to reduce morbidity and mortality rates of invasive cervical carcinoma. Herein, we report a case of 56-year-old woman whose cervicovaginal smear was found to consist of malignant cells characterized by high nuclear/cytoplasmic ratio, scant rim of cytoplasm, coarsely granular nuclear chromatin and irregular nuclear membrane that were all reminiscent of a malignant lymphoma. Histopathological examination of the hysterectomy and unilateral adnexectomy specimen confirmed the presence of a diffuse large B-cell non Hodgkin's lymphoma involving the cervix, endometrium, myometrium, serosa and the right ovary.

Purpose: Several studies performed on pancreatic-duodenal homeobox 1 (PDX1) have demonstrated a loss of expression and negative tumor modulator effect in gastric carcinoma. Relations between PDX1 and gastric metaplasia, differentiated type of gastric carcinoma, and the early stage of the disease have been exhibited in previous reports. The aim of this study was to examine expressions of PDX1, caudal type homeobox 2 (CDX2) and mucin (MUC) profiles to address the role of PDX1 in gastric carcinogenesis and its relationship with CDX2.

Laryngeal malignant tumors are mainly composed of squamous cell carcinomas. Glandular carcinomas of the larynx are rare tumors that constitute less than 1% of all laryngeal malignancies where "adenocarcinoma not otherwise specified" is the most common histologic subtype. Here we report a case of a 70-year-old female patient with primary laryngeal mucinous adenocarcinoma.
