Evolving Pathology of Anaplastic Thyroid Carcinoma: Integrating Morphology, Immunohistochemistry, and Molecular Insights

Cancer Science, EarlyView.
Schematic overview of progression from differentiated thyroid carcinoma (DTC) to anaplastic thyroid carcinoma (ATC). ATC primarily develops via two pathways: the BRAF p.V600E‐mutated papillary thyroid carcinoma (PTC) pathway and the RAS‐mutated pathway. The origin and progression of BRAF/RAS‐wildtype ATC remain unclear.

Superficial Ewing Sarcoma of the Rectum: A Case Report and the Utility of Molecular Diagnostics

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Ewing sarcoma is an undifferentiated small round cell sarcoma that most commonly presents as a malignant bone tumor in pediatric and young adult patients. The diagnosis is typically confirmed by molecular genetic identification of a fusion protein, most commonly involving members of the FET and ETS gene families.

Advances and Challenges in the Multidisciplinary Treatment of Retroperitoneal Infantile Fibrosarcoma in Early Life

European Journal of Haematology, EarlyView.
ABSTRACT Background and Aims Retroperitoneal Infantile Fibrosarcoma (RIFS) is a rare, locally aggressive pediatric soft tissue tumor. Its retroperitoneal location poses challenges due to proximity and potential invasion of critical structures such as the inferior vena cava (IVC).

Absence of DNA viruses in ameloblastomas

European Journal of Oral Sciences, EarlyView.
Abstract Ameloblastomas (ABs) are rare odontogenic benign tumors. Although studies of the molecular pathogenesis have revealed the presence of mutations and altered gene expression, the etiology is unresolved. Viruses cause 10%–15 % of cancers, but their potential role within benign tumors is less studied.

Perineurioma‐like EMA‐positive calvarial neoplasms: clinicopathological study of eight cases

Histopathology, EarlyView.
Perineurioma‐like, EMA‐positive calvarial neoplasms (PLECN) are a rare group of intraosseous spindle cell tumours that demonstrate overlapping morphologic features of perineurioma and fibroblastic meningioma. These lesions tend to behave indolently but show a propensity for progressive growth.

Cutaneous Leiomyosarcoma of the Skin: An Updated Review of Epidemiology, Pathogenesis, and Management

International Journal of Dermatology, EarlyView.
This review provides an update on the epidemiology, pathogenesis, and clinical/histologic features of cutaneous leiomyosarcoma. Prognostic factors (e.g., depth of tumor involvement, grade, etc.) that can facilitate risk stratification are also discussed, as are treatment approaches for this rare malignancy.

Australian clinical practice guideline: diagnosis and treatment of idiopathic multicentric Castleman disease

Internal Medicine Journal, EarlyView.
Abstract Idiopathic multicentric Castleman disease (iMCD) is a rare condition. The pathogenesis is incompletely understood; however, interleukin‐6 (IL‐6) is a major mediator. The clinical presentation is heterogeneous, from mild constitutional symptoms to severe multi‐organ failure.
