Primary Pulmonary Epithelioid Angiosarcoma Presenting in a 59-Year-Old Woman: A Report of a Rare Case.

Primary pulmonary angiosarcomas are rare malignancies, with aggressive clinical behavior and poor prognosis. Here we present a case of a rare primary pulmonary epithelioid angiosarcoma in a 59-year-old woman who initially presented with right-sided chest pain and shortness of breath. Chest X-ray revealed right lower lobe atelectasis, while a chest computed tomography angiography (CTA) showed a large right hydrothorax with collapse of most of the right lung.

A Primary Telangiectatic Mandibular Osteosarcoma With Germ-Line Malignancy-Associated DNA Damage Repair Gene Polymorphisms: A Case Report.

Primary mandibular telangiectatic osteosarcomas are very rare lesions, with only nine cases reported. Histologically, these lesions show multiple cystic blood-filled cavities traversed by neoplastic bone in septa lined by high-grade malignant cells. Here, we report an 81-year-old woman who presented with a mandibular mass, which was surgically resected and analyzed by histologic examination and whole exome DNA sequencing.

A Rare Case of Solitary Fibrous Tumor of the Kidney.

Solitary fibrous tumor (SFT), originally described in the pleura, is a rare mesenchymal neoplasm characterized by a wide spectrum of clinical presentations and histopathological features. Over the years, SFTs have been reported in various anatomical locations, including soft tissues, visceral organs, and, uncommonly, the kidney. While SFTs primarily arise from the pleura, their occurrence in the kidney is an infrequent phenomenon, accounting for a minute fraction of all renal tumors.

A unique presentation of a rare renal cancer: Appearance of bone metaplasia in tubulocystic renal cell carcinoma.

Tubulocystic renal cell carcinoma is a rare cancer that was not defined as a distinct entity until the early 2000s. Due to the recency of its classification, it remains poorly understood and leaves much room for future research. This report looks at a unique case of this rare subtype of renal cancer.
