Expression of BMP4 and FOXN1 in orthokeratinized odontogenic cyst compared to odontogenic keratocyst suggests an epidermal phenotype.

Biotech Histochem 2022 May 9:1-9. Epub 2022 May 9.

Department of Oral Medicine and Pathology and Hospital Dentistry, National and Kapodistrian University of Athens, Athens, Greece.

Odontogenic keratocysts (OKC) and orthokeratinized odontogenic cysts (OOC) are odontogenic cysts that share histological and immunohistochemical similarity with epidermal appendages and cutaneous cystic lesions despite exhibiting contrasting biological behavior. In epidermal appendages, BMP4 induces expression of FOXN1, which participates in terminal differentiation of keratinocytes and control of proliferation. We compared BMP4 and FOXN1 expression in OOC and OKC to investigate their role in the epithelial differentiation of these cysts. Read More

Epidermoid cyst in an intrapancreatic accessory spleen with abnormally high CEA level in cyst fluid: a case report.

Autops Case Rep 2022 14;12:e2021369. Epub 2022 Apr 14.

United Christian Hospital, Department of Pathology, Hong Kong, China.

Epidermoid cyst in an intrapancreatic accessory spleen is a rare benign lesion that is difficult to diagnose preoperatively. Cyst fluid analysis for biochemistry markers has been widely used to aid the diagnosis of pancreatic cysts. A high cyst fluid carcinoembryonic antigen (CEA) level (>800 ng/mL) is said to be useful in distinguishing intraductal papillary mucinous neoplasm (IPMN) and mucinous cystic neoplasm (MCN) from other non-mucinous cysts.

Activation of the EGFR/MAPK pathway drives transdifferentiation of quiescent niche cells to stem cells in the testis niche.

Elife 2022 04 25;11. Epub 2022 Apr 25.

Department of Cell Biology, Johns Hopkins University School of Medicine, Baltimore, United States.

Adult stem cells are maintained in niches, specialized microenvironments that regulate their self-renewal and differentiation. In the adult testis stem cell niche, somatic hub cells produce signals that regulate adjacent germline stem cells (GSCs) and somatic cyst stem cells (CySCs). Hub cells are normally quiescent, but after complete genetic ablation of CySCs, they can proliferate and transdifferentiate into new CySCs. Read More

Mucoepidermoid carcinoma - A common neoplasm at an unusual site, mimicking a benign cyst on cytology: Diagnostic pitfall!

J Oral Maxillofac Pathol 2022 Feb 28;26(Suppl 1):S30-S33. Epub 2022 Feb 28.

Department of Pathology, Kasturba Medical College, Manipal, Karnataka, India.

Mucoepidermoid carcinoma (MEC) is known to be a relatively common neoplasm of the major and minor salivary glands that can secondarily involve skin. The clinical manifestations, diagnostic cytology and histopathology of MEC presenting as a clinically benign periauricular cystic nodule have been analyzed. The challenge of accurate diagnosis can be illustrated by the fact that initially, on cytology, this tumor was misdiagnosed as a benign epidermal inclusion cyst due to the presence of mucin-filled cells which were misinterpreted as cyst macrophages.

Identification of Codon 146 Variants in Isolated Epidermal Nevus and Multiple Lesions in Oculoectodermal Syndrome: Confirmation of the Phenotypic Continuum of Mosaic RASopathies.

Int J Mol Sci 2022 Apr 6;23(7). Epub 2022 Apr 6.

Center for Medical Genetics Ghent, Ghent University Hospital, 9000 Ghent, Belgium.

Mosaic RASopathies are a molecularly heterogeneous group of (neuro)cutaneous syndromes with high phenotypical variability. Postzygotic variants in have been described in oculoectodermal syndrome (OES), encephalocraniocutaneous lipomatosis (ECCL) and epidermal nevus syndrome (ENS). This study confirms the continuum of mosaic neurocutaneous RASopathies showing codon 146 variants in an individual with OES and, for the first time, in an individual with (isolated) epidermal nevus.
