Hyaline bodies may be found in the optic disc and in several parts of the retina as a nonspecific finding (Wolter, 1959). The term drusen ("colloid bodies") is usually reserved for large hyaline bodies of the optic disc and Bruch's membrane. Lorentzen (I966), postulated that drusen of the optic disc had an irregular dominant pattern of inheritance after an examination of the relatives of 49 aff...

Osteochondral lesions of the talus are generally the result of trauma and often result in persistent pain and disability. Various treatment options have evolved to treat these challenging problems, ranging from conservative management to marrow stimulation and cartilage or chondrocyte transplantation. Microfracture is the first line of treatment for many of these lesions. However, there is conc...

Background. Castleman's disease is a benign lymphoproliferative disorder. The disease may be localized or multicentric. Three histologic variants are recognized: hyaline vascular, plasma cell, and mixed types. Case. A 20-year-old man presented with large left axillary mass. The histologic examination of the resected mass showed follicular pattern with large nodules of mantle cells arranged conc...

A nine year old boy with localised Castleman disease of the hyaline-vascular subtype developed a calcifying fibrous pseudotumour. This pathological association does not appear to have been described before. In this case, the development of this very unusual soft tissue tumour-like process was thought to be related to a previous fine needle aspiration biopsy, which was performed because of lymph...

Two patients are reported in whom initial misdiagnoses of medullary cancer or trabecular hyaline adenoma for papillary carcinoma were made.

Heavy metal metals are non-biodegradable, have a remarkable ability to transfer through food chains and are potentially toxic for organisms.They are introduced tomarine environment via different anthropogenic sources. In this study, the ability of titanium dioxide nano-particle in transfer of Cr, Cu, Pb and Se metal through an aquatic food chain involving Ceratium tripos as the phytoplankton Da...

We describe here a three year-old girl with classic clinical and histological features of juvenile hyaline fibromatosis. We found a history of similar skin findings in her eldest sister, in whom the disorder took a rapidly progressive and fatal course in the second year of life, suggesting either a very severe form of juvenile hyaline fibromatosis, or the possibility of infantile systemic hyali...
