Solitary fibrous tumors (SFTs) are a rare type of sarcoma and ubiquitous in nature, occurring anywhere in the body. Although only a few hundred cases have been described so far, certain histological features, such as hypercellularity and high mitotic index, have been associated with a more malignant course. Tumor sizes larger than 10 cm have also been associated with higher recurrence rates. There are clinical recommendations for two distinct patient groups, those with small and benign SFTs or those with large and malignant SFTs. There are few that acknowledge the unique group of those with large but benign tumors. A case involving a 62-year-old man who underwent surgical resection of a large but benign solitary fibrous tumor of the pelvis is described.

Adult-Onset Pediatric-Type Follicular Lymphoma of the Parotid Gland.

Pediatric-type follicular lymphoma (PTFL) is an extremely rare B-cell lymphoma that primarily affects children and young adults, typically in individuals under 25 years old, with a median age of 15 years. Here, we report a rare case of PTFL in a 27-year-old adult male who presented with a slow-growing mass near his left ear. Initial CT scans of the neck revealed two oval-shaped, smooth, well-defined, homogeneously enhancing soft tissue density lesions in the superficial lobe of the left parotid gland.

Background: Routine screening to detect silent but deadly cancers such as pancreatic ductal adenocarcinoma (PDAC) can significantly improve survival, creating an important need for a convenient screening test. High-resolution proton (1H) magnetic resonance spectroscopy (MRS) of plasma identifies circulating metabolites that can allow detection of cancers such as PDAC that have highly dysregulated metabolism.
Methods: We first acquired 1H MR spectra of human plasma samples classified as normal, benign pancreatic disease and malignant (PDAC).

Background: Human papillomavirus (HPV) is a common infection of the anogenital tract. Although most infections clear, persistent infections with oncogenic types can predispose to cancer. While the natural history of anogenital HPV infection in cisgendered women is relatively well understood, there are significant knowledge gaps regarding HPV prevalence and clinical implications of genital HPV infection in transgender women (TGW) with neovagina(s).

Canine acanthomatous ameloblastoma (CAA) is an invasive benign epithelial odontogenic tumour most commonly affecting the mandible of large breed dogs. To the author's knowledge, this report describes the first computer-aided design patient-specific implant (PSI) that has been placed for a critical sized bone defect in mandibular reconstruction of a dog in the UK. The aim was to restore mandibular stability using a regenerative approach combining a titanium locking plate and compression-resistant matrix infused with recombinant human bone morphogenetic protein-2 (rhBMP-2) to bridge the 85 mm mandibular defect created by a segmental mandibulectomy.

Breast cancer (BC) is a prevalent malignancy in women, often necessitating tumor resection and breast reconstruction surgeries. However, the post-operation scars can be of concern, as hypertrophic scars (HS) can profoundly impact patients' quality of life. Our study used the bidirectional Mendelian randomization (MR) method to explore the potential relationship between BC and HS.
