Primitive non-neural granular-cell tumor (PNGCT) is a rare tumor of uncertain lineage. It was first described by Le Boit et al. [1] as “primitive polypoid granular cell tumor” after analysis of four cases. Since then various other names have been proposed. Lazar et al. called it “primitive non-neural granular cell tumor” [2] and Chaudhry et al. coined the term “dermal non-neural granular cell t...
The etiology and histogenesis of granular cell tumor are still debated. Granular cell tumor of the newborn is considered to be a different entity than the adult form of this lesion with different immunohistochemical features. We present a case of a rare gingival granular cell tumor in a newborn and review the literature. Gingival granular cell tumor must be clinically differentiated from terato...
Introduction: Granular cell tumors (GCTs) are rare and mostly benign soft tissue tumors. Though they have been reported in all parts of body, they are generally located in the head and neck region, especially on the tongue. Some malign forms exist, but these have been rarely reported. Granular cell tumors have a neural origin and, in immunohistochemical evaluations, they express S-100 and neuro...
Granular cell tumors are an uncommon soft tissue neoplasm. Malignant granular cell tumors comprise <2% of all granular cell tumors, are associated with aggressive behavior and poor clinical outcome, and are poorly understood in terms of tumor etiology and systematic treatment. Because of its rarity, the genetic basis of malignant granular cell tumor remains unknown. We performed whole-genome se...
We report on a case of extraluminal tracheal granular-cell tumor which was interpreted as a Hurthle-cell neoplasm of the thyroid on fine-needle aspirate. Review of the literature reveals only one other such case. The patient was a 35-yr-old female who presented with an enlarged thyroid. Aspiration cytology revealed a syncytium of cells with abundant granular cytoplasm interpreted as a thyroid f...
BACKGROUND Granular cell tumors are rare neoplasms which can occur in any part of the body. Granular cell tumors of the orbit account for only 3 % of all granular cell tumor cases. Computed tomography and magnetic resonance imaging of the orbit have proven useful for diagnosing orbital tumors. However, the rarity of intraorbital granular cell tumors poses a significant diagnostic challenge for ...
Granular cell tumor is a rare tumor of unknown etiology that more commonly affects the oral cavity but can also occur at other sites. The majorities of granular cell tumors are benign and present as a singular dermal nodule. We discuss a case of granular cell tumor of the fourth toe in a 54-year-old patient that was treated with conservative surgery, instead of amputation, and reconstruction wi...
