The expression of caveolin-1 and -2 in the retina was examined; Western blot analysis showed that both were present. Immunohistochemistry indicated that caveolin-1 was expressed in the majority of retinal layers, including the ganglion cell layer, inner plexiform layer, outer plexiform layer, and in the vascular endothelial cells of the retina. Caveolin-2 was primarily immunostained in the vess...
Neurofibromatosis type 1 (NF1), also known as peripheral neurofibromatosis or von Recklinghausen's disease, is one of the most common genetic disorders. It is inherited in an autosomal dominant pattern. Multiple cutaneous neurofibromas are hallmark lesions of NF1. Localized and plexiform neurofibromas of the paraspinal and sacral region are the most common abdominal neoplasms in NF1. Herein, we...
Very recently, Requena et al. have demonstrated the detailed clinicopathological features of 9 cases of a benign cutaneous plexiform nerve sheath tumor with hybrid characteristics of perineurioma and cellular neurothekeoma, given the name as a benign cutaneous plexiform hybrid tumor of perineurioma and cellular neurothekeoma, all of which were peculiarly located on the lips. Herein we described...
Schwannomas are slow-growing nerve sheet neoplasms which are rarely found in the female genital system. In this article, we present a patient with Antony A congenital plexiform schwannoma of the clitoris. A 6-year-old girl was brought to our hospital with the history of a firm non-cystic clitoral mass from birth, which had been growing more rapidly during the previous year. The patient was sche...
Ameloblastoma is characteristically considered to be a benign but locally aggressive and infiltrative odontogenic tumor with high recurrence rate. Because of its invasive nature, the rates for ameloblastoma post treatment remains high. Recurrence also seems depend on histological type modalities used. Curettage alone reported have led 90% rate mandibular tumors 100% maxillary in literature. In ...
An immunohistochemical study of the distribution of tyrosine hydroxylase has been performed in the retina of lizards of the genera Podarcis, Anolis and Tarentola. Immunoreactive cells extending their processes into the inner plexiform layer were observed in all three species. Reactive fibres in the outer plexiform layer were also seen in Podarcis and Anolis, and hence they possess not only amac...
In oral cavity neurogenic tumors are rare, especially if they are malignant. Neurofibromas are the benign tumors of nerve sheath origin involving multiple nerve fascicles of the smaller branches of peripheral nerves. They may present as solitary lesions or as a part of generalized syndrome of neurofibromatosis also known as von Recklinghausen's disease (VRD) or very rarely as multiple neurofibr...
