چکیده

Blue nevi are dermal dendritic melanocytic proliferations presenting as papules, nodules or plaques of blue, blue-gray or blue-brown color. Dermoscopic appearance commonly shows global patterns as homogeneous mono/dichromatic pigmentation and multichromatic pigmentation. Here, we report the case of a blue nevus with the dermoscopic feature of peripheral streaks with branches. With histopathologic deep sections, we confirmed that dermal dendritic melanocytes were distributed in the direction of the streaks. We emphasize that streaks are a rare but important sign of blue nevi.

Correlation of dermoscopic structures of melanocytic lesions to reflectance confocal microscopy.

OBJECTIVE To determine the utility of reflectance confocal microscopy (RCM) in the in vivo evaluation of dermoscopic structures of melanocytic lesions. DESIGN For each described dermoscopic feature, we evaluated by RCM at least 2 melanocytic lesions. A digital camera connected to the confocal computer enabled direct analysis of the dermoscopic structures. To ascertain precision of correlation...

Blue nevus with a starburst pattern on dermoscopy

An 11-year-old girl presented to our department with a blue-gray papule approximately 4 mm in diameter. We suspected that it was a blue nevus or a pigmented Reed/Spitz nevus. On dermoscopic observation, the lesion showed homogeneous black-bluish pigmentation. This dermoscopic feature was suggestive of a blue nevus. However, near-circumferential streaks and a global feature of a "starburst patte...

Amelanotic melanoma mimicking cutaneous epitheliomas.

DERMOSCOPIC APPEARANCE The dermoscopic analysis (Fig 2) revealed peripheral dotted vessels, linear irregular vessels, milky red areas, and white streaks, suggestive of melanoma. However, there were no structures or vascular patterns found in cutaneous epitheliomas, such as leaf-like areas, blue-gray ovoid nests, or arborizing or glomerular vessels. It is noteworthy that no brown, black, gray, o...

Melanoma and satellite blue papule

The colors that are seen in dermoscopy depend on the anatomic level of the skin at which the chromophores are seen. Blue color can be found in a variety of melanocytic and nonmelanocytic lesions. An 89-year-old man presented with a 3-year history of a slow-growing, hyperpigmented patch located on the distal third of the right arm. Dermoscopy showed an atypical network, irregularly distributed g...

Dermoscopic characteristics of melanoma according to the criteria „ulceration“ and „mitotic rate“ of the AJCC 2009 staging system for melanoma

OBJECTIVE The present study was conducted to identify possible dermoscopic patterns, associated with mitotic rate > 1/mm2, histological ulceration in melanoma and metastatic disease. METHODS For this retrospective data analysis all clinical and dermoscopic digital images of primary malignant melanomas between 2008 and 2013 documented at the Department of Dermatology Graz were included, using ...
