Congenital Oral Masses: An Anatomic Approach to Diagnosis.

Radiographics 2019 Jul-Aug;39(4):1143-1160

From the Department of Radiology and Biomedical Imaging, University of California, San Francisco, 505 Parnassus Avenue, San Francisco, CA (M.C.C., Y.L., D.J.S., O.A.G., C.M.G., J.L.C.) and the Russell H. Morgan Department of Radiology and Radiological Science, Johns Hopkins University School of Medicine, Baltimore, MD (B.P.S.).

Although congenital oral masses are rare, they are readily detectable during fetal US screening. Most congenital oral masses are benign, but some may cause mechanical airway obstruction, resulting in poor outcomes at delivery. The radiologist's ability to describe these abnormalities and their physiologic sequelae accurately can have a substantial effect on perinatal treatment. Read More

Cutaneous Non-Neural Granular Cell Tumors Harbor Recurrent ALK Gene Fusions.

Am J Surg Pathol 2018 09;42(9):1133-1142

Departments of Pathology.

Non-neural granular cell tumor (NNGCT; also known as primitive polypoid granular cell tumor) is a rare neoplasm composed of large ovoid cells with abundant granular cytoplasm, variable nuclear pleomorphism, and the potential for regional lymph node spread. In contrast to conventional granular cell tumor (GCT), NNGCT lacks S100 expression and can exhibit greater nuclear atypia and mitotic activity. Therefore, we investigated clinicopathologic features of 12 NNGCT, and also used next-generation sequencing to identify potential driver events in a subset of NNGCT and 6 GCT. Read More

Oral peripheral nerve sheath tumors: A clinicopathological and immunohistochemical study of 32 cases in a Brazilian population.

J Clin Exp Dent 2017 Dec 1;9(12):e1459-e1465. Epub 2017 Dec 1.

DDS, MSc, PhD, Professor, Area of Pathology, School of Dentistry, Federal University of Uberlândia, Uberlândia, MG, Brazil.

Background: Oral peripheral nerve sheath tumors (OPNSTs) are reactive or neoplastic diseases that develop from proliferation of the nerve itself or their limiting sheaths. Here we describe the clinicopathologic data of OPNSTs observed in a sample of the Brazilian population and evaluate the expression of molecules associated with neural biology to determine their usefulness in the diagnosis.

Material And Methods: Descriptive study of cases diagnosed as OPNSTs, from the Pathology Laboratory at the School of Dentistry/ Federal University of Uberlandia, followed by an immunohistochemical study of S-100, CD57, neurofilament protein (NFP) and epithelial membrane antigen (EMA). Read More

A rare case of perianal granular cell tumor: case report and literature review.

J Surg Case Rep 2017 Jun 6;2017(6):rjw186. Epub 2017 Jun 6.

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

Granular cell tumor mimicking a squamous cell carcinoma of the tongue: a case report.

BMC Res Notes 2017 Jan 3;10(1):14. Epub 2017 Jan 3.

Department of Oral Medicine (Oral Pathology), Dental School, Faculdade de Odontologia, Universidade Federal de Goiás, Praça Universitária, S/N, Setor Universitário, Goiânia-Goiás, CEP 74605-220, Brazil.

Background: Granular cell tumor is a rare benign tumor that can present a pseudoepitheliomatous hyperplasia of the covering epithelium. 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.
