Steroidogenic Factor 1 (SF1) Immunohistochemical Stain Is Sensitive and Specific for the Cytopathologic Identification of Intrapancreatic Ectopic Splenic Tissue

Diagnostic Cytopathology, EarlyView.
ABSTRACT Background Accessory spleens result from failure of splenic fusion during development and are occasionally located in the pancreatic tail, radiographically appearing as solid or solid/cystic lesions. Fine needle aspiration (FNA) easily identifies accessory spleens in most samples based on architecture and using CD8 to highlight splenic ...

Pancreatic Adenocarcinoma: Diagnosis by Ultrasound‐Guided Fine‐Needle Aspiration—Cyto‐Histological Correlation and Experience at a Multidisciplinary Tertiary Reference Center

Diagnostic Cytopathology, EarlyView.
ABSTRACT Background Pancreatic adenocarcinoma (PDAC) is characterized by its poor prognosis. Cytology is essential for diagnostic confirmation and ancillary studies. The endoscopic ultrasound (EUS) set a precedent, facilitating cytological sampling through fine‐needle aspiration (FNA), with a sensitivity of 93% and a specificity of 95%.

Activation of Gαq sequesters specific transcripts into Ago2 particles

Scientific Reports, 2022
The Gαq/phospholipase Cβ1 (PLCβ1) signaling system mediates calcium responses from hormones and neurotransmitters. While PLCβ1 functions on the plasma membrane, there is an atypical cytosolic population that binds Argonaute 2 (Ago2) and other proteins ...

Treatment responses to antiangiogenetic therapy and chemotherapy in nonsecreting paraganglioma (PGL4) of urinary bladder with SDHB mutation: a case report [PDF]

, 2018
Paraganglioma (PGL) is a rare neuroendocrine tumor. Currently, the malignancy is defined as the presence of metastatic spread at presentation or during follow-up.

Cytomorphology and Molecular Profile of Hyalinizing Clear Cell Carcinoma of the Lung: A Case With Mucinous Differentiation

Diagnostic Cytopathology, EarlyView.
ABSTRACT Hyalinizing clear cell carcinoma (HCCC) of the lung is an exceedingly rare salivary gland‐type neoplasm with limited cytomorphologic description. We report a case highlighting these features. A 3 mm incidental left‐airway lesion enlarged to 7 mm over 5 months, prompting radial endobronchial ultrasound (EBUS)‐guided transbronchial biopsy. Touch

Deceptive Thyroid Pathologies: Anaplastic Thyroid Carcinoma Mimics and Clinical Implications

Head &Neck, EarlyView.
ABSTRACT Background Beyond follicular‐derived thyroid carcinomas, lymphomas, and metastatic disease, there are rare pathologies of the thyroid gland that represent a challenge. We report patients with unusual malignancies that mimic similar aggressive cancers. Methods Retrospective case series.

Molecular–clinical characteristics and treatment outcomes in 163 metastatic colorectal neuroendocrine carcinomas with a comparison to colorectal adenocarcinomas

International Journal of Cancer, EarlyView.
What's New? Colorectal neuroendocrine carcinoma (CR‐NEC) is a rare digestive neuroendocrine neoplasm that frequently exhibits an adenocarcinoma component. Nonetheless, the underlying biology of CR‐NEC remains poorly understood. This study examined molecular and clinical features and palliative chemotherapy outcomes of metastatic CR‐NEC, with comparison
