Twelve cases of distal digital keratoacanthoma (DKA) affecting the subungual area or the proximal nail fold are reported. The distal phalanx of the toe was affected in three cases. Spontaneous resolution occurred in one; one other recurred after surgery. We also discuss the link between DKA and incontinentia pigmenti subungual ...
Farnsworth T A - - 1998
Primary intracranial melanomas are rare and occur mainly in young adults. Originating from leptomeningeal melanoblasts and extending into the parenchyma, the tumours closely resemble meningiomas, from which they are radiologically difficult to distinguish despite progress in neuroimaging. Definitive diagnosis is usually made on histopathological examination, though confirmed only after post-mortem ...
Lale A M - - 1998
Haemangiomas are the commonest benign tumours of the head and neck in childhood, but they are extremely rate on the palate. We report a case of a palatal haemangioma presenting with feeding difficulties in a young infant. Clinical diagnosis and pathological features are discussed and we suggest a classification which ...
Tornesello A - - 1998
Veno-occlusive disease of the liver (VOD) is an important complication in children with Wilms' tumour. Although in most patients this complication resolves uneventfully, fatal cases have been reported. Several observations strongly suggest that actinomycin-D is the likeliest cause of VOD in Wilms' tumour, but VOD seems to be rather uncommon ...
Sharma M C - - 1998
Gliofibromas are rarely encountered astrocytic tumours comprising of astrocytic and benign fibroblastic components. They commonly occur in first two decades of life. However, the exact behaviour is not fully known and their histogenesis is also still debatable. We report three cases of gliofibroma in which we studied proliferative markers (MIB-1) ...
