The diagnosis of seborrheic keratosis is, in general, a clinical one, but in s ome cases, the differential diagnosis between pigmented seborrheic keratosis and malignant melanoma is difficult. Dermoscopy may improve the early diagnosis of vulvar melanoma and thus play a role in the preoperative classification of pigme nted lesions at this particular site. We report the first case of a pigmented se borrheic keratosis of the vulva clinically mimicking a malignant melanoma, whose dermoscopic features have been investigated together with their pathologic corr elates. Dermoscopically our case shows the absence of comedo-like openings and the presence of the pseudo-network. Dermoscopy is therefore a useful method for the differential diagnosis of pigmented lesions even in the vulva. 展开更多

In order to investigate the possible role of dermoscopy in the non-invasive classification of combined nevi, we analyzed dermoscopic features of a series of combined nevi consecutively excised. Two dermatologists expert in dermoscopy retrospectively evaluated all images based on the presence of dermoscopic findings to analyze which epiluminescence microscopy features were more frequently associated with each type of combined nevus. Dermoscopy may provide useful information in the non-invasive diagnosis of combined nevi, allowing a conservative management, but this may be limited to combined nevi including a blue nevus component. Conversely, combined nevi including a Spitz nevus component may be difficult to classify even by dermoscopy, thus requiring careful monitoring or surgical excision. 展开更多

Completely amelanotic melanomas are rare and therefore often misclassified, with tragic consequences for patients. The use of dermoscopy for these lesions has not been validated yet because of the lack of studies that are based on large series. The analysis of the vascular pattern, which is often the only dermoscopic parameter to be seen, is therefore essential for a correct diagnosis. We present a case of “ true” amelanotic melanoma on the forehead of an 89- year- old man, which clinically mimicked squamous cell carcinoma. The patient was investigated both clinically and by focusing on his dermoscopic features and their pathologic correlates. The dermoscopic diagnostic algorithms routinely used for pigmented lesions are not helpful in diagnosing amelanotic melanoma because they are based on specific parameters not normally seen in amelanotic lesions. In the light of our experience, pattern analysis is the most reliable method for diagnosing these particular lesions correctly because it allows in- depth morphologic analysis of the few parameters found. 展开更多
