Ephrin-A1, formerly called B61, is a new melanoma growth factor; it is angiogenic and chemoattractant for endothelial cells. EPH-A2, or ECK (a receptor for ephrin-A1), is ectopically expressed in most melanoma cell lines; the pathology where this expression is first manifested and the possible role of the receptor in tumor progression are unknown. To(More)
Background beta-Catenin is a crucial member of the E-cadherin/catenin complex, which plays a major role in cell-cell adhesion. beta-Catenin is also known to be involved in signal transduction pathways. Many studies have demonstrated changes in the expression of beta-catenin in colorectal carcinomas, suggesting a role for beta-catenin in neoplastic(More)
Angiokeratoma corporis diffusum (ACD) is still often thought to be synonymous with Anderson-Fabry disease, a deficiency of alpha-galactosidase. It is important, however, to consider other possible enzyme deficiencies in patients with ACD. We report an 8-year-old boy with neurodevelopmental delay who was diagnosed as having fucosidosis following recognition(More)
Using silver (Ag) staining to demonstrate nucleolar organizer region-associated proteins (AgNORs), pigmented naevi exhibiting features of melanocytic dysplasia have been examined and compared with benign intradermal and compound naevi and with malignant melanomas. A highly significant difference was found between the numbers of AgNORs demonstrated in benign(More)
Using Ulex europaeus I lectin (UEA1) to demonstrate endothelial cells, we have previously shown that frequency of capillary invasion correlates closely with maximum tumor thickness in primary cutaneous melanoma. UEA1 demonstrates both vascular and lymphatic capillaries; however, only vascular capillaries possess basement membranes. In order to ascertain(More)
BACKGROUND Controversy exists concerning the necessary margin of excision for cutaneous melanoma 2 mm or greater in thickness. METHODS We conducted a randomized clinical trial comparing 1-cm and 3-cm margins. RESULTS Of the 900 patients who were enrolled, 453 were randomly assigned to undergo surgery with a 1-cm margin of excision and 447 with a 3-cm(More)
Schwannomas are benign encapsulated tumours arising from the sheaths of peripheral nerves. They present as slowly enlarging solitary lumps, which may cause neurological defects. Multiple lesions are rare, but occur in patients with neurofibromatosis type 2 or schwannomatosis. Positive outcomes have been reported for surgical excision in solitary(More)
Sebaceous carcinomas are uncommon amongst cutaneous malignancies. These lesions can broadly be classified into 2 groups; (i) periorbital, which behave aggressively, and (ii) extraorbital, which are reported to metastasize rarely. A retrospective review has identified 12 cases of primary sebaceous carcinoma treated at Canniesburn Hospital over the decade(More)
From a retrospective analysis of 180 surgical interventions for soft tissue sarcoma of the limbs and trunk, it was concluded that complete excision of the tumour can usually be achieved without sacrifice of major artery, vein, nerve or bone. In this series five major arteries were resected but only one required reconstruction. None of six resected major(More)
