BACKGROUND: Over the past decade numerous epiluminescence microscopy (ELM) criteria and algorithmic methods have been developed to improve the diagnosis of cutaneous melanocytic lesions.
OBJECTIVE: Our purpose was to compare the sensitivity, specificity, and diagnostic accuracy of 3 algorithmic methods (pattern analysis, ABCD rule of dermoscopy, and the 7-point checklist) on a series of highly atypical melanocytic lesions. We also determined the diagnostic value of distinct ELM ...

BACKGROUND: Amelanotic malignant melanoma is a subtype of cutaneous melanoma with little or no pigment on visual inspection. It may mimic benign and malignant variants of both melanocytic and nonmelanocytic lesions.
OBJECTIVES: To evaluate whether dermoscopy is also a useful technique for the diagnosis of amelanotic/hypomelanotic melanoma (AHM).
METHODS: We conducted a retrospective clinical study of 151 amelanotic/hypomelanotic skin lesions from 151 patients with a mean age of 47 years ...

OBJECTIVE: To determine the predictive dermoscopic features of amelanotic and hypomelanotic melanoma.
DESIGN: A total of 105 melanomas (median Breslow thickness, 0.76 mm), 170 benign melanocytic lesions, and 222 nonmelanocytic lesions lacking significant pigment (amelanotic, partially pigmented, and light colored) were imaged using glass-plate dermoscopy devices and scored for 99 dermoscopic features. Diagnostic models were derived from and tested on independent randomly selected ...

IMPORTANCE: Nodular melanoma (NM) is a rapidly progressing potentially lethal skin tumor for which early diagnosis is critical.
OBJECTIVE: To determine the dermoscopy features of NM.
DESIGN: Eighty-three cases of NM, 134 of invasive non-NM, 115 of nodular benign melanocytic tumors, and 135 of nodular nonmelanocytic tumors were scored for dermoscopy features using modified and previously described methods. Lesions were separated into amelanotic/hypomelanotic or pigmented to assess ...

Negative pigment network: An additional dermoscopic feature for the diagnosis of melanoma
[ PUBLICATION ]
BACKGROUND: The negative pigment network (NPN) is seen as a negative of the pigmented network and it is purported to be a melanoma-specific structure.
OBJECTIVES: We sought to assess the frequency, sensitivity, specificity, and odds ratios (ORs) of NPN between melanoma cases and a group of control lesions.
METHODS: Digitalized images of skin lesions from 679 patients with histopathological diagnosis of dermatofibroma (115), melanocytic nevus (220), Spitz nevus (139), and melanoma (205) ...

Although the long experience acquired with the widespread use of dermoscopy has allowed the establishment of criteria for the recognition of benign and malignant skin lesions, very few data are available on cutaneous melanoma metastases. As the characteristic clinical aspects are multiform and even histological evaluation may sometimes be difficult, we have studied and characterized the patterns of cutaneous melanoma metastases in dermoscopy. In this paper, we report dermoscopic data on ...

Pigmented nodular melanoma: the predictive value of dermoscopic features using multivariate analysis
[ PUBLICATION ]
BACKGROUND: Nodular melanoma (NM), representing 10-30% of all melanomas, plays a major role in global mortality related to melanoma. Nonetheless, the literature on dermoscopy of NM is scanty.
OBJECTIVES: To assess odds ratios (ORs) to quantify dermoscopic features of pigmented NM vs. pigmented superficial spreading melanoma (SSM), and pigmented nodular nonmelanocytic and benign melanocytic lesions.
METHODS: To assess the presence or absence of global patterns and dermoscopic criteria, ...

BACKGROUND: Whether timing of sentinel lymph node biopsy (SLNB) in cutaneous melanoma improves survival is not yet clear. The aim of this study was to investigate if the timing of SLNB influences long-term melanoma mortality.
METHODS: A 10-year retrospective cohort study was conducted on 748 cutaneous melanoma patients who underwent excision of the SLN. Hazard ratios and 95% confidence intervals were estimated from Cox proportional hazards models.
RESULTS: After adjusting for sex, age, ...

BACKGROUND: Differential diagnosis of melanoma from melanocytic nevi is often not straightforward. Thus, a growing interest has developed in the last decade in the automated analysis of digitized images obtained by epiluminescence microscopy techniques to assist clinicians in differentiating early melanoma from benign skin lesions.
PURPOSE: The aim of this study was to evaluate diagnostic accuracy provided by different statistical classifiers on a large set of pigmented skin lesions ...

BACKGROUND/PURPOSE: The relationship between diseases and alterations of the airborne chemicals emitted from the body has been found in many different pathologies and in particular for various forms of cancer. Metabolism of cancer cells is greatly altered during their lifetime; then, modification of chemicals is supposed to be large around cancer tissues. Positive hints in this direction were provided, as an example, on studying the breath composition of lung cancer-affected subjects. ...

Amelanotic melanoma (AM) is a rare subtype of melanoma with little or no clinically visible pigment; it is more difficult to diagnose than pigmented melanoma (PM), and has a worse prognosis. In the attempt to find a genetic explanation for the distinction between AM and PM, we conducted a case-case study, matching AM and PM patients, and testing them for germline mutations in high- (p16INK4A, p14ARF, CDK4) and low-penetrance (MC1R) melanoma susceptibility genes. Similar CDKN2A mutations ...

BACKGROUND: The morphologic capillary microscopy (capillaroscopy) pattern of acrocyanosis is characterized by hemorrhages, pericapillary edema, and widened capillaries. These findings can result in a difficult differential diagnosis with systemic sclerosis (SSc).
OBJECTIVE: We sought to quantify the characteristics of the capillaroscopy pattern that distinguishes patients with acrocyanosis from patients with SSc and control subjects.
METHODS: A videomicroscope with fiberoptic ...

BACKGROUND: The clinical and dermoscopic differentiation between lentigo maligna (LM) and solar lentigo (SL)/initial seborrheic keratosis (SK) may be difficult.
OBJECTIVE: Our aim was to identify digital epiluminescence microscopy (DELM)-specific criteria that can be helpful in distinguishing LM from SL/SK and to propose a new model of LM dermoscopic progression based on a study of DELM-histopathological correlation.
METHODS: A total of 167 consecutive doubtful pigmented lesions of the ...
