The surgical pathologist plays a crucial role in the multidisciplinary team. In nearly all cases, a tissue diagnosis is required to confirm the disease process before treatment begins. Even in settings where the diagnosis appears straightforward, a timely and appropriate report is necessary. The pathologist is also responsible for providing many of the more specific data elements that will guide treatment decisions: examples include evidence of virally driven malignancy, margin status, and the precise depth to which tumor invades. Each of these diagnoses and findings has its own specific set of difficulties and limitations, which require nuanced interpretation by a well-informed pathologist.

Blood sampling is often performed during animal studies. This is more challenging in mice than in larger animal species owing to their size and lack of blood vessel visibility. Guidelines for blood sampling in mice and papers on animal welfare often refer to the submandibular, cheek, buccal, and anterior facial veins.

Head and neck squamous cell carcinoma (HNSCC) is genetically complex and difficult to treat. Detection in the early stage is challenging, leading to diagnosis at advanced stages with limited treatment options. This study examined the collagen triple helix repeat containing 1 gene (CTHRC1) as a potential biomarker and therapeutic target in HNSCC.

Fibro-osseous tumors of the craniofacial bones are a heterogeneous group of lesions comprising cemento-osseous dysplasia (COD), cemento-ossifying fibroma (COF), juvenile trabecular ossifying fibroma (JTOF), psammomatoid ossifying fibroma (PsOF), fibrous dysplasia (FD), and low-grade osteosarcoma (LGOS) with overlapping clinicopathological features. However, their clinical behavior and treatment differ significantly, underlining the need for accurate diagnosis. Molecular diagnostic markers exist for subsets of these tumors, including GNAS mutations in FD, SATB2 fusions in PsOF, mutations involving the RAS-MAPK signaling pathway in COD, and MDM2 amplification in LGOS.

Introduction: Large melanomas, while relatively uncommon, present significant diagnostic challenges due to their size and potential to mimic other malignancies, leading to delays in appropriate treatment. Initial misdiagnosis is a substantial concern, impacting patient outcomes. This case highlights the importance of immunohistochemistry in cancer diagnosis, and of appropriate therapeutic management, which here included excision surgery of the tumor mass.

Background: Adenoid cystic carcinoma (ACC) is a rare malignant tumor that accounts for <1 % of head and neck malignancies, with an estimated involvement of the tongue at approximately 3 %.
Case Presentation: This report presents a case of a 42-year-old male with no significant history of tobacco or alcohol use, who developed a painless, progressively enlarging mass on the ventral surface of his tongue over the course of eight months. Initial surgical resection confirmed the diagnosis of ACC, which necessitated a right hemiglossectomy followed by radiotherapy to address potential residual disease.
