Schwannomas are benign peripheral nerve sheath tumors originating from the Schwann cells. Most schwannomas in the head and neck region are solitary; however, multiple schwannomas affecting one or more nerves suggest a possible association with neurofibromatosis type 2 and schwannomatosis. Plexiform schwannoma is a rare variant of conventional schwannoma that is characterized by intraneural multinodular growth. Read More

Granular cell tumours are rare neoplasms that may occur anywhere in the body. The most common locations are the oral cavity, skin and subcutaneous tissue, with only 8% of these tumours occurring at a gastrointestinal site. In the specific case of gastric granular cell tumours, only a few cases have been published until today. Read More

When faced with an uncertain clinical pathosis in the oral cavity, identifying the color of the mucosal lesion helps to narrow down a differential diagnosis. Although less common than red and white lesions, yellow lesions encompass a small group of distinct mucosal pathologic entities. Adipose tissue, lymphoid tissue, and sebaceous glands are naturally occurring yellow constituents of the oral cavity and become apparent with associated developmental or neoplastic lesions.

Zinc finger AN1-type containing 4 (ZFAND4) has emerged as a promising prognostic marker and predictor of metastasis for patients with oral squamous cell carcinoma (OSCC). However, further validation is fundamental before clinical implementation. Hence, this study evaluated the expression pattern of ZFAND4 protein expression by immunohistochemistry using an independent cohort of 125 patients with OSCC, and correlations with the clinicopathologic parameters and disease outcome.

Large-cell neuroendocrine tumors (NETs) are poorly differentiated malignancies of rare incidence and aggressive nature. NETs mostly arise in the lung followed by the gastrointestinal tract, although they are potentially ubiquitous throughout the body. Primary unknown NET has a worse prognosis and shorter survival comparing with other NETs, with limited available data in the literature concerning this subgroup. Read More

A diverse spectrum of benign oral mucosal lesions exists, presenting as either isolated oral findings or in association with dermatological conditions. Oral lesions can closely resemble one another; therefore, it is important for clinicians to be able to recognize their distinctive features and recognize benign versus malignant disease and when a biopsy is warranted. In this continuing medical education series, we review oral anatomy and the clinical attributes of several benign lesions of the oral cavity along with the appropriate management and therapeutic modalities.

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

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

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.
