common acquired nevi and an otherwise normal clinical examination. Congenital melanocytic nevi are often classified according to their size [1] . Another attempt of classification in two groups has recently been proposed: type I, the most frequent, with a single lesion involving one anatomic area and type II, less common, with a larger lesion and dozens of smaller ones, with a similar pattern o...

A well known but often neglected fact is that malignant melanoma frequently originates ih a pigmented nevus that has remained quiescent for many years. The urgent need for eradication of such lesions before malignant transformation occurs cannot be stressed too often, In addition to emphasizing the validity of the above statements, the case here reported presents features which are somewhat uni...

BACKGROUND Marathon running has surged in popularity; it is generally believed to be healthy, but may be associated with medical risks. Over the past decade, we observed 8 ultramarathon runners with malignant melanoma. UV exposure, immunosuppression due to long-term intensive exercise, or both have been discussed as potential triggers in these patients. To further evaluate risk factors for mali...

OBJECTIVE To compare identification of the border of lentigo maligna (LM) with digital epiluminescence microscopy (DELM) with clinical and Wood light assessment. DESIGN The borders of lesions identified clinically with the Wood light, with DELM, and after excision by Mohs micrographic surgery were traced onto plastic sheets. The borders defined on the tracings were compared for congruence and...

Bilateral diffuse uveal melanocytic hyperplasia (BDUMH) is a rare but well known paraneoplastic syndrome,' associated with systemic malignancy. An essential feature of this syndrome is a preponderantly benign looking cytology of the melanocytic tumours.' We describe the clinical and histopathological features ofBDUMH with active proliferation and bilateral ciliary body malignant melanomas. The ...

The aim of this work was to explore the potential infrared thermal imaging as an aiding tool for diagnosis skin cancer lesions, using artificial intelligence methods. Thermal parameters tumours were retrieved from thermograms and used input features two machine learning based strategies: ensemble deep learning. strategy outperformed one, showing good predictive performance differentiation melan...

OBJECTIVE (a) To determine whether children given chemotherapy for haematological malignancy have significantly more melanocytic naevi than age matched children in the local population; (b) to establish whether any observed variation in naevus counts from normal is seen at the start of maintenance chemotherapy. DESIGN Follow up of 29 consecutive children starting maintenance chemotherapy, wit...

Dermoscopy is a non-invasive tool that is largely recognized and used in the diagnosis of pigmented and non-pigmented skin tumors. A steadily increasing number of publications on alternative applications of dermoscopy suggest, however, that dermoscopy aids also the recognition of skin manifestations in general dermatology. The increasing use of dermoscopy in general dermatology can be partially...
