Background: Dermal clear cell sarcoma (DCCS) is a rare malignant mesenchymal neoplasm. Owing to the overlaps in its morphological and immunophenotypic profiles with a broad spectrum of tumors exhibiting melanocytic differentiation, it is frequently misdiagnosed as other tumor entities in clinical practice. By systematically analyzing the clinicopathological characteristics, immunophenotypic features, and molecular biological properties of DCCS, this study intends to further enhance pathologists' understanding of this disease and provide a valuable reference for its accurate diagnosis.

The spindle cell variant of papillary thyroid carcinoma (PTC) is exceptionally rare and poses significant diagnostic challenges due to its morphological overlap with other spindle cell lesions of the thyroid. We report a novel case of spindle cell variant PTC in a 66-year-old woman presenting with a TI-RADS 4 thyroid nodule, initially classified as Bethesda III on fine-needle aspiration. Histopathological examination revealed a biphasic tumor composed predominantly of bland spindle cells arranged in solid sheets and fascicles, admixed with entrapped thyroid follicles.

To explore the clinicopathological and molecular genetic characteristics of anaplastic lymphoma kinase (ALK)-rearranged renal cell carcinoma (RCC), including a rare case with the TPM1-ALK gene subtype. Three cases of ALK-rearranged RCC diagnosed in the Department of Pathology, the First Affiliated Hospital of Zhengzhou University, Zhengzhou, China from January 2020 to December 2024 were collected. Their clinical pathological and next-generation sequencing (NGS) data were analyzed.

Initial management typically includes thoracic endovascular aortic repair (TEVAR) or aortic graft replacement to achieve hemostasis, followed by esophagectomy with aortic graft replacement and greater omentum wrapping to eliminate the source of infection. We report a case of successful endoscopic closure of a chronic esophageal fistula secondary to AEF.

Existing microscopy approaches are often unable to identify and contextualize rare but biologically meaningful events due to limitations associated with simultaneously achieving both high-resolution imaging and a cm-scale field of view. Here, we present multiscale cleared tissue axially swept light-sheet microscopy (MCT-ASLM), a platform combining cm-scale imaging with targeted high-resolution interrogation of intact tissues in human-guided or autonomous modes. Capable of capturing fields of view up to 21 mm at micron-scale resolution, MCT-ASLM can seamlessly transition to a targeted imaging mode with an isotropic resolution that approaches ∼300 nm.
