Bronchiolar adenoma with unusual presentation: Two case reports.

World J Clin Cases 2022 May;10(14):4541-4549

Department of Pathology, The Affiliated Hospital of Shandong First Medical University (Liaocheng People's Hospital), Liaocheng 252000, Shandong Province, China.

Background: The clinicopathological features, immunohistochemical characteristics, and genetic mutation profile of two unusual cases of distal bronchiolar adenoma are retrospectively analyzed and the relevant literature is reviewed.

Case Summary: Case 1 was a 63-year-old female patient who had a mixed ground-glass nodule, with mild cells in morphology, visible cilia, and bilayer structures in focal areas. Immunohistochemical staining for P63 and cytokeratin (CK)5/6 revealed the lack of a continuous bilayer structure in most areas, and no mutations were found in epidermal growth factor receptor, anaplastic lymphoma kinase, ROS1, Kirsten rat sarcoma, PIK3CA, BRAF, human epidermal growth factor receptor-2 (HER2), RET, and neuroblastoma RAS genes.

Early differential responses elicited by BRAF in adult mouse models.

Cell Death Dis 2022 02 10;13(2):142. Epub 2022 Feb 10.

Telomeres and Telomerase Group, Molecular Oncology Program, Spanish National Cancer Centre (CNIO), Melchor Fernández Almagro 3, Madrid, E-28029, Spain.

The BRAF gene is frequently mutated in cancer. The most common genetic mutation is a single nucleotide transition which gives rise to a constitutively active BRAF kinase (BRAF) which in turn sustains continuous cell proliferation. The study of BRAF murine models has been mainly focused on the role of BRAF in tumor development but little is known on the early molecular impact of BRAF expression in vivo. Read More

Glucocorticoid Receptor Antagonism Upregulates Somatostatin Receptor Subtype 2 Expression in ACTH-Producing Neuroendocrine Tumors: New Insight Based on the Selective Glucocorticoid Receptor Modulator Relacorilant.

Front Endocrinol (Lausanne) 2021 4;12:793262. Epub 2022 Jan 4.

Drug Research and Development, Corcept Therapeutics, Menlo Park, CA, United States.

Somatostatin exhibits an inhibitory effect on pituitary hormone secretion, including inhibition of growth hormone and adrenocorticotropic hormone (ACTH), and it can have antisecretory and antitumor effects on neuroendocrine tumors (NETs) that express somatostatin receptors. Although the precise mechanism remains unclear, the finding that glucocorticoids downregulate somatostatin receptor subtype 2 (SSTR2) expression has been used to explain the lack of efficacy of traditional SSTR2-targeting analogs in patients with ACTH-secreting NETs. Glucocorticoid receptor (GR) antagonism with mifepristone has been shown to reverse the glucocorticoid-induced downregulation of SSTR2; however, the effects of GR modulation on SSTR2 expression in ACTH-secreting NETs, particularly corticotroph pituitary tumors, are not well known.

J Cardiothorac Surg 2021 Oct 18;16(1):307. Epub 2021 Oct 18.

Department of Cardiothoracic Surgery, The Third Affiliated Hospital, Sun Yat-Sen University, 600 Tianhe Road, Guangzhou, 510630, Guangdong, People's Republic of China.

Background: Bronchiolar adenoma (BA) is a recently proposed diagnostic terminology, which is considered as the expansion of the concept of ciliated muconodular papillary tumors. BA is considered to be a benign neoplasm, but a few previous cases have been reported with the possibility of malignant transformation. Therefore, the genetic and histological nature of BA is controversial so far. Read More

Ann Diagn Pathol 2021 Dec 4;55:151837. Epub 2021 Oct 4.

A.M. Rywlin, MD Department of Pathology, Mount Sinai Medical Center, Miami Beach, FL 33140, USA; Florida International University, Herbert Wertheim College of Medicine, Miami, FL 33199, USA.

Bronchiolar adenomas (BAs)/ciliated muco-nodular papillary tumors (CMPTs), are small, peripheral lung nodules arising predominantly in the elderly that follow a benign course. They can be mistaken for adenocarcinomas on frozen section. Immunohistochemistry (IHC) for basal cell markers highlights the continuous layer of basal cells underlying the tumor cells in BAs.

Division of Pulmonary Sciences and Critical Care Medicine, School of Medicine, University of Colorado Anschutz Medical Campus, Aurora, Colorado.

Lung cancer chemoprevention with the prostacyclin analogue iloprost is the most promising approach to date for intercepting progression of premalignant lung lesions in former smokers. Previous preclinical studies of iloprost used oral delivery, but a study modeling delivery directly to the target organ was needed. and studies have identified gene expression changes following iloprost treatment, including increased e-cadherin and and decreased and vimentin.

Electronic address:

The management of endogenous Cushing's syndrome (CS) typically involves two key steps: (i) confirmation of autonomous hypercortisolism and (ii) localization of the cause to guide treatment. Adrenocorticotropic hormone (ACTH)-dependent CS is most commonly due to a pituitary corticotrope tumor which may be so small as to evade detection on conventional magnetic resonance imaging (MRI). Although biochemical testing (e. Read More
