  • The two component pattern and the multi-component symmetric pattern are commonly encountered in patients with the atypical mole syndrome. However, if it is an outlier lesion compared with the patient’s other neviThis glossary term has not yet been described. then one should consider a biopsy or close digital monitoring to ensure stability.
  • The homogeneous tan to pink nevus is a common pattern seen in nevi in individuals with type I-II skinThis glossary term has not yet been described.. However, this pattern can also be seen in amelanotic and hypomelanotic melanomas. Thus, if such lesions appear to be outliers, caution should be exercised.
  • The tiered peripheral globular patternThis glossary term has not yet been described. is associated with nevi having a spitzoid morphologyThis glossary term has not yet been described. on dermoscopyThe examination of [skin lesions] with a 'dermatoscope'. This traditionally consists of a magnifier (typically x10), a non-polarised light source, a transparent plate and a liquid medium between the instrument and the skin, and allows inspection of skin lesions unobstructed by skin surface reflections. Modern dermatoscopes dispense with the use of liquid medium and instead use polarised light to cancel out skin surface reflections.. While the managementThis glossary term has not yet been described. of spitzoid lesions remains controversial, if such a lesion develops in older ageprocess of becoming older, then one should consider a biopsy.
  • The typical starburst patternThis pattern consists of peripheral globules, pseudopods or streaks (or a combination of them), located around the entire perimeter of the lesion is associated with Reed’s nevi. While this is usually a benignis any condition that is harmless in the long run pattern, on rare occasions melanoma can masquerade itself as a starburst pattern lesion. Thus, a classic starburst pattern in individuals under the age of 12 can be monitored, however, such lesion in older individuals should be viewed with suspicion.
