Sinonasal teratocarcinosarcoma (SNTCS) is a rare and highly malignant tumour with combined features of a teratoma and carcinosarcoma. We report the first case of a SNTCS in 23 year old male treated with neo-adjuvant chemotherapy followed by cranio-facial resection. The resection specimen displayed cellular maturation in the neuroectodermal component. The patient presented with a short history o...
Primitive neuroectodermal tumor (PNET) is a rare disease and mostly diagnosed in children and young adults. This tumor is presumed to be of neuroectodermal origin, probably developing from migrating embryonic cells of the neural crest. Carcinoembryonic antigen is a glycoprotein and frequently elevated in patients with a variety of epithelial malignancies. We report hereby a 59-year old male pat...
Ewing sarcoma/primitive neuroectodermal tumor is a rare tumor of soft tissues of thoracopulmonary regions, pelvis and lower extremities. Involvement of visceral organs by primitive neuroectodermal tumor is even rarer, with the kidney being the most commonly involved organ. Involvement of the liver has been reported in the form of metastasis from other primary sources presenting as liver abscess...
Melanotic neuroectodermal tumor of infancy (MNTI) is a relatively uncommon osteolytic-pigmented neoplasm that primarily affects the jaws of newborn infants. Here, we are reporting a case of MNTI presented at the age of 12 years. The objective of this report is to review the incidence, presentation, investigation protocols, management options and outcomes.
Here we report that aloe-emodin (AE), a hydroxyanthraquinone present in Aloe vera leaves, has a specific in vitro and in vivo antineuroectodermal tumor activity. The growth of human neuroectodermal tumors is inhibited in mice with severe combined immunodeficiency without any appreciable toxic effects on the animals. The compound does not inhibit the proliferation of normal fibroblasts nor that ...
The primary neuroectodermal tumor of the ovary is extremely rare, and it manifests in 3 forms: differentiated, primitive, and anaplastic. The medulloblastoma belongs to the subgroup of primitive neuroectodermal tumor of the ovary. Only 3 cases of ovarian medulloblastoma have been reported in the literature, and all of them are presented without information about the specific pathological subtyp...
