A previously healthy woman, aged 38 years, presented with a 3-month history of fatigue, dyspnea on exertion, significant weight loss, and severe left flank pain; her symptoms restricted any work activities. Laboratory test results were notable for hypercalcemia (corrected serum calcium, 12.8 mg/dL), anemia (9.3 g/dL), and lactate dehydrogenase elevation (>1.5 times the upper limit of normal). A CT scan revealed a 14-cm left renal mass and multiple lung and mediastinal lymph node metastases. A surgical open biopsy was performed; histopathological analysis concluded clear cell renal carcinoma (RCC) with 30% sarcomatoid features. The patient was diagnosed with International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) poor-risk metastatic RCC with sarcomatoid features. She started first-line systemic treatment.

To understand the clinicopathological and molecular genetic characteristics of aggressive renal mucinous tubular and spindle cell carcinoma (MTSCC). The clinical features, histology, immunophenotype, molecular characteristics and prognosis of 4 cases of metastatic/recurrent renal MTSCC that were submitted to the Peking University Third Hospital (2 cases), Institute of Urology, Peking University (one case) and Zhejiang Provincial People's Hospital (one case) from 2015 to 2020 were retrospectively reviewed and analyzed. Among the four patients, two were male and two were female.

Background: Hepatic sarcomatoid carcinoma (HSC) and hepatic sarcoma (HS) are rare malignancies. Without pathology, the differential diagnosis between these two tumors is difficult due to their frequent overlaps in clinical presentations and imaging features. Currently, there are limited analyses about the ultrasound (US), contrast-enhanced ultrasound (CEUS) and contrast-enhanced computer tomography (CECT) characteristics of HSC and HS.

Purpose: Most bladder cancers are pure urothelial carcinomas, but a small portion, approximately 5-10%, have variant histology or are non-urothelial in nature. This research sought to examine the features of and treatment strategies for different types of urothelial carcinoma with variant histologies and non-urothelial bladder cancer.
Methods: The study cohort comprised individuals with non-urothelial and variant urothelial bladder cancers treated at two medical centres in Ankara, Turkey, between 2005 and 2024.

Desmoplastic malignant peritoneal mesothelioma (DMPM) is an extremely rare and aggressive subtype of sarcomatoid malignant mesothelioma, originating from the mesothelial lining of body cavities. It is characterized by significant local invasiveness and poor prognosis. The nonspecific symptoms of DMPM often result in delayed diagnosis.

Purpose: The clinicopathologic features, mutational status, immunohistochemical markers, and prognosis of Pulmonary sarcomatoid carcinoma (PSC) remain uncertain.
Methods: This study included 81 PSC and 337 lung adenocarcinomas (LUAD). Progression-free survival (PFS), overall survival (OS), and other clinical data were examined.
