Congenital gingival granular cell tumor is a rare benign lesion of uncertain origin, which has been found only in newborn infants. This article describes one such case. Our immunohistochemical study employing antibodies against S-100 protein, epithelial membrane antigen, carcinoembryonic antigen, wide-spectrum keratin, desmin and vimentin yielded data supporting the theory of a mesenchymal cell...

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 imm...

granular cell tumors are rare neoplasms of uncertain histogenesis but with a typical histologic appearance composed of cells with characteristic granular cytoplasm. these tumors occur most often in adults as an asymptomatic solitary papule or nodule. multiple granular cell tumors are rare, especially in children and teenagers. we represent a case of multiple granular cell tumors in a 19-year-ol...

Congenital granular cell lesion (CGCL) is a rare non-neoplastic lesion found in newborns also known as Neumann's tumor. This benign lesion occurs predominantly in females mostly as a single mass. The histogenesis and natural history of the lesion remains obscure. It arises from the mucosa of the gingiva, either from the maxillary or mandibular alveolar ridge. The lesion is more common in the ma...
