“…Furthermore, some congenital acral naevi have a homogeneous blue pattern, as reported by Garrido‐Ríos et al . Samimi et al . reported that ultrasonography is a reproducible tool that can assist in the differential diagnosis between blue naevus and melanoma metastases, but there should be a clinical suspicion present.…”

Background Cutaneous metastases of malignant melanoma (CMMM) can be confused with other skin lesions. Dermoscopy could be helpful in the differential diagnosis. Objective To describe distinctive dermoscopic patterns that are reproducible and accurate in the identification of CMMM Methods A retrospective study of 146 dermoscopic images of CMMM from 42 patients attending a Melanoma Unit between 2002 and 2009 was performed. Firstly, two investigators established six dermoscopic patterns for CMMM. The correlation of 73 dermoscopic images with their distinctive patterns was assessed by four independent dermatologists to evaluate the reproducibility in the identification of the patterns. Finally, 163 dermoscopic images, including CMMM and non-metastatic lesions, were evaluated by the same four dermatologists to calculate the accuracy of the patterns in the recognition of CMMM. Results Five CMMM dermoscopic patterns had a good inter-observer agreement (blue nevus-like, nevus-like, angioma like, vascular and unspecific). When CMMM were classified according to these patterns, correlation between the investigators and the four dermatologists ranged from κ = 0.56 to 0.7. 71 CMMM, 16 angiomas, 22 blue nevus, 15 malignant melanoma, 11 seborrheic keratosis, 15 melanocytic nevus with globular pattern and 13 pink lesions with vascular pattern were evaluated according to the previously described CMMM dermoscopy patterns, showing an overall sensitivity of 68% (between 54.9–76%) and a specificity of 81% (between 68.6–93.5) for the diagnosis of CMMM. Conclusion Five dermoscopic patterns of CMMM with good inter-observer agreement obtained a high sensitivity and specificity in the diagnosis of metastasis, the accuracy varying according to the experience of the observer.

“…In addition, the use of echography may help to differentiate blue nevi from a blue-colored melanoma metastasis, because blue nevi are generally dish-shaped and have a homogeneous echo whereas melanoma metastases are potato-shaped and show an inhomogeneous echo. 36 …”

Blue color is found in a wide range of malignant and benign melanocytic and nonmelanocytic lesions and in lesions that result from penetration of exogenous materials, such as radiation or amalgam tattoo or traumatic penetration of particles. Discriminating between different diagnostic entities that display blue color relies on careful patient examination and lesion assessment. Dermoscopically, the extent, distribution, and patterns created by blue color can help diagnose lesions with specificity and differentiate between benign and malignant entities. This article provides an overview of the main diagnoses whereby blue color can be found, providing simple management rules for these lesions.

“…Acoustic shadowing and retrolesional echogenicity may assist the diagnosis between benign naevus and melanoma (18) Quantitative discrimination of pigmented lesions seems possible using three-dimensional high-resolution ultrasound reflex transmission imaging (19). Blue naevi are also hypoechoic, and often have a dish shape or an ovoid shape ( Fig.3a and 3b) (20). …”

“…They are often visible or palpable, and may simulate a benign blue naevus. However, the shape of the lesion is different for a blue naevus and a recurrence of melanoma (20). Moreover, ultrasound examination is able to detect subclinical in transit recurrence in some cases.…”
