HAEMANGIOMAS are well-known formations; they occur all over the body although they are exceedingly rare in the orbit. It is not our intention here to discuss the pathology of these neoplasms or malformations, as this has already been done adequately by Ewing (1940), Boyd (1947), and Willis (1948). For a comprehensive bibliography on orbital tumours and, in particular, on orbital haemangiomas, r...

BACKGROUND Cavernous hemangiomas are rare tumors, mainly localized in the liver and skin, but also reported in the cerebellum and eye fundus as a part of von Hippel Lindau Syndrome. Adrenal hemangiomas are less than 1% of all the adrenal neoplasms and usually are reported as benign, non-functioning tumors, originating from the adrenal cortex and surrounded by normal or hyperplastic adrenal tiss...

Eye tumors of the retinal pigment epithelium (RPE) have been thought generally to be benign, whereas choroidal ones are malignant. To test this assumption in mice, the W/Wv (Kit) mutant genotype was introduced into melanoma-prone transgenic mice whose recombinant simian virus 40 transforming sequences are specifically expressed in pigment cells. W/Wv causes programmed death of neural crest-deri...

despite of the fact that the vulva contains a high density of apocrine and anogenital mammary glands in addition to eccrine glands and folliculosebaceous units, the benign vulvar adnexal tumours are rare. though the varied clinical presentation and diverse histopathological spectrum of vulvar neoplasms has amazed the pathologists, only few studies have been reported in literature. the present f...

Dermoscopy is a non-invasive skin imaging technique, which permits visualization of features of pigmented melanocytic neoplasms that are not discernable by examination with the naked eye. One of the most important features for the diagnosis of melanoma in dermoscopy images is the blue-white veil (irregular, structureless areas of confluent blue pigmentation with an overlying white "ground-glass...
