Granular cell type of ameloblastoma.

Dent Res J (Isfahan) 2018 May-Jun;15(3):224-227

Department of Oral and Maxillofacial Surgery, School of Dentistry, Isfahan University of Medical Sciences, Isfahan, Iran.

Ameloblastoma is a locally invasive tumor derived from odontogenic epithelium. An uncommon variant of ameloblastoma is granular cell type, which cannot distinguish from other ameloblastoma subtypes by clinical and radiographic findings alone. Only review of it's microscopic features allows distinction from other subtypes. Read More

Oral Verruciform Xanthoma within Lichen Planus: A Case Report and Literature Review.

Case Rep Dent 2018 22;2018:1615086. Epub 2018 Apr 22.

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

Background: Verruciform xanthoma is an uncommon benign tumor, which exhibits a wide range of clinical patterns. The occurrence of the lesion in patients with immune-mediated mucocutaneous diseases may suggest a role of localized epithelial cell damage and chronic inflammation in its pathogenesis.

Mucocele of the dorsal surface of the tongue: A case report.

J Clin Exp Dent 2018 May 1;10(5):e495-e498. Epub 2018 May 1.

Department of Oral Medicine and Pathology, Dental School, University of Athens, Greece.

Mucoceles represent one of the most common lesions of the oral cavity, developing as a result of saliva accumulation. The most frequent affected area is the lower lip, followed by floor of mouth, ventral tongue and buccal mucosa. Despite numerous reports of mucoceles originating on the ventral surface of the tongue, only scarce cases of such a lesion identified on the dorsal tongue surface have been described. Read More

Epidermal growth factor receptor (EGFR) density may not be the only determinant for the efficacy of EGFR-targeted photoimmunotherapy in human head and neck cancer cell lines.

Lasers Surg Med 2018 Jul 19;50(5):513-522. Epub 2018 May 19.

Department of Otorhinolaryngology and Head and Neck Surgery, Center for Optical Diagnostics and Therapy, Erasmus Medical Center, Rotterdam, The Netherlands.

Objective: The aim of this study was to investigate the effects of targeted photoimmunotherapy (PIT) in vitro on cell lines with various expression levels of epidermal growth factor receptor (EGFR) using an anti-EGFR targeted conjugate composed of Cetuximab and IR700DX, phthalocyanine dye.

Materials And Methods: Relative EGFR density and cell binding assay was conducted in three human head & neck cancer cell lines (scc-U2, scc-U8, and OSC19) and one reference cell line A431. After incubation with the conjugate for 1 or 24 hours, cellular uptake and localization were investigated by confocal laser scanning microscopy and quantified by image analysis. Read More

Department of Surgery, Boca Raton Regional Hospital, Charles E. Schmidt College of Medicine, Florida Atlantic University, Boca Raton, FL, USA.

Granular cell tumor (GCT) is a rare submucosal neoplasm most commonly localized in the oral mucosa; with one-third of all cases found in the tongue, with less than 30 cases of perianal GCT reported in the literature, making it a rare anal neoplasm. Wide local excision is the gold standard of treatment and follow-up includes annual colonoscopy due to the high incidence of reoccurrence. Here we describe a rare case of benign perianal GCT in a 29-year-old female who presented asymptomatically; however, pathology report revealed a S100 positive immunostaining pattern. Read More

This lesion is not encapsulated and can be characterized by a pseudo invasive growth pattern, represented by the tumoral cells that infiltrate between adjacent connective tissue elements. Diagnostic difficulties may arise because histopathological features of the pronounced pseudoepitheliomatous hyperplasia can be confused with a well-differentiated oral squamous cell carcinoma.

Department of Oral Pathology, I.T.S. Centre for Dental Sciences and Research, Murad Nagar, Ghaziabad, Uttar Pradesh, India.

Background: The B cell lymphoma-2 gene is a proto-oncogene whose protein product inhibits apoptosis. Its role is associated with keeping cells alive, but not by stimulating them to proliferation, as other proto-oncogenes do. Increased expression of protein product of Bcl-2 gene appears in the early phase of carcinogenesis leading to apoptosis impairment and in consequence to the progression of neoplastic changes.

Dept of General Surgery, Peoples College of Medical Sciences, Bhanpur bypass road, Bhopal.

Congenital granular cell tumor is a rare benign neoplastic growth affecting the gingival mucosa of neonates. Prenatal ultrasound diagnosis has recently come to focus and in spite of several reports on immune-histochemical and other advanced marker studies, the cause and origin of the lesion remains debatable till date. Review of literature on prenatal diagnosis and histopathology along with immunohistochemistry is discussed. Read More

Proflavine Hemisulfate as a Fluorescent Contrast Agent for Point-of-Care Cytology.

PLoS One 2015 11;10(5):e0125598. Epub 2015 May 11.

Biomedical Engineering Department, University of Arkansas, Fayetteville, Arkansas 72701, United States of America.

Proflavine hemisulfate, an acridine-derived fluorescent dye, can be used as a rapid stain for cytologic examination of biological specimens. Proflavine fluorescently stains cell nuclei and cytoplasmic structures, owing to its small amphipathic structure and ability to intercalate DNA. In this manuscript, we demonstrated the use of proflavine as a rapid cytologic dye on a number of specimens, including normal exfoliated oral squamous cells, cultured human oral squamous carcinoma cells, and leukocytes derived from whole blood specimens using a custom-built, portable, LED-illuminated fluorescence microscope.
