Description	This chapter describes the 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. pattern seen in benignis any condition that is harmless in the long run neviThis glossary term has not yet been described..

Reticular patternA lesion with a reticular pattern has typical pigment network throughout the entire lesion.

A lesion with a reticular pattern has typical pigment networkNetwork with minimal variability in the color, thickness, and spacing of the lines; symmetrically distributed delicate network light brown, thin network lines throughout the entire lesion.

Patchy reticular patternA patchy network pattern is a benign pattern composed of islands of pigment network symettrically distributed throughout the entire lesion.

Peripheral reticular with central hyperpigmentationIn this benign pattern we see typical pigment network at the periphery of lesion with a central dark structureless area.

Peripheral reticular with central hypopigmentationIn this benign pattern we see typical pigment network at the periphery of a lesion with a central light stuctureles area. This is seen very frequently in compound nevi.

This is a benign pattern composed of regular globulesGlobules with minimal variability in their color, size and shapeGlobules with minimal variability in their color, size and shape

Peripheral reticular with central globulesThis is a benign pattern with peripherl reticulation (pigment network) and regular globules in the center

This is a benign pattern with peripherl reticulation (pigment networkGrid-like pattern consisting of interconnecting pigmented lines surrounding hypopigmented holes.) and regular globules in the center

Homogenous patternstructureless any color

Homogenous brown pattern

This benign pattern is frequently seen in congenital neviis a type of melanocytic nevus (or mole) found in infants at birth. This type of birthmark occurs in an estimated 1% of infants worldwide; it is located in the area of the head and neck 15% of the time.

Homogenous tan pattern

This benign pattern is frequently seen in nevi in redheads

Homogenous blue pattern

This benign pattern is frequently seen in blue nevu

Peripheral rim of globules patternThis pattern is currently seen in growing lesions.

This pattern is currently seen in growing lesions.

Teared globules at the periphery

This pattern is typically seen in Spitz neviThis glossary term has not yet been described.

Peripheral streaks (starburst patternThis pattern consists of peripheral globules, pseudopods or streaks (or a combination of them), located around the entire perimeter of the lesion)

This pattern is typically seen in Spitz / Reed nevi

Multicomponent patterns

This pattern can be seen in a kissing nevus (collision of 2 nevi) or in atypical or malignantThis glossary term has not yet been described. lesions. We recommend either follow up or excision of these lesions.

Multi component pattern

A multi component pattern consists of a combinationThis glossary term has not yet been described. of reticular, globular and homogenous patternstructureless any color in the same lesion. If the multi component pattern is symmetric throughout the lesion we recommend follow up or excision. It the multicomponent patternThis glossary term has not yet been described. is assymetric, we recommend excision of the lesion.
