In human subjects with peripheral retinal detachments, visual deficits are not restricted to the detached retina but are also present in the non-detached tissue. Based upon studies on a rabbit model of rhegmatogenous retinal detachment, we propose a glial cell-mediated mechanism of spread of retinal degeneration into non-detached retinal areas which may also have importance for the understandin...

A schwannoma is a benign tumor arising from a schwann cell and occurs mainly in the nerve sheath in the intradural extramedullary region. Schwannomas have been well described as occurring in the lumbar spine, but total cystic degeneration of schwannomas is rarely reported. The authors describe the clinical and radiographic evaluations and treatment of a rare case of an intraextradural totally c...

A case of carcinosarcoma arising within an otherwise benign cystic teratoma is reported. The patient, a 78 year old nulliparous woman, presented with right sided abdominal pain of short duration and subsequently underwent a bilateral salphingo-oophorectomy. Slicing of the left ovary revealed a unilocular cyst containing hair admixed with soft yellow material with a thin wall apart from a solid ...

Spinal muscular atrophy (SMA) is a neuromuscular disorder characterized by degeneration of alpha motor neurons resulting in hypotonia, progressive muscular weakness and atrophy.30 Spinal muscular atrophy is one of the leading hereditary causes of infant mortality,31 it comprises the second most common fatal progressive diseases after cystic fibrosis.28 Spinal muscular atrophy is the most common...

A case is described of primary hyperparathyroidism in a patient with both a parathyroid cyst within the thymus gland and a concomitant parathyroid adenoma. The parathyroid adenoma contained microcystic areas of degeneration, and it is thought that the parathyroid cyst reflected degenerative change in a pre-existing adenoma. Parathyroid cyst should be considered in the differential diagnosis of ...

Proliferating trichilemmal cysts, also known as pilar tumors, are slow-growing lobulated masses most commonly found on the scalp of elderly women. We present the case of a 69-year-old woman with a 25-year history of multiple enlarging scalp masses. The patient was evaluated for surgical consultation after the dominant mass presented with malignant degeneration. A CT of the head revealed multipl...

Case details: The present study reports 77 years old, with no family history cancer, presented gynecomastia an irregular mass infra-axillary region, central cystic degeneration, classified as BIRADS IV-A. patient evolved multiple lytic bon...
