Parallel Furrow Pattern

Parallel Furrow Pattern - No lines or rounded structures. Linear pigmentation, predominantly localized to the furrows. Complete asymmetry suggests the lesion may be malignant, but may also be seen in some atypical naevi. Web in contrast, the main dermoscopic pattern of acral nevus is the parallel furrow pattern (pfp) showing linear pigmentation along the sulci of the skin markings. The fibrillar pattern appears more likely in lesions on weight bearing sites, and the lattice pattern on the arch of the foot. Diffuse, scattered, central or peripheral. Diffuse pigmentation of different shades of brown colour not respecting furrows or ridges. Linear pigmentation of the ridges. A combination of many pigmentation patterns; Genetic alterations are also different between the two types of lesion.

A Combination Of Many Pigmentation Patterns;

Diffuse pigmentation of different shades of brown colour not respecting furrows or ridges. Web as according to the literature, the dermoscopic pattern of parallel ridges has 86% sensibility and 99% specificity to detect acral melanomas, and benign lesions often present the parallel furrow pattern. Web the parallel furrow pattern most often appears in naevi on the side of the foot. Complete asymmetry suggests the lesion may be malignant, but may also be seen in some atypical naevi.

Web In Contrast, The Main Dermoscopic Pattern Of Acral Nevus Is The Parallel Furrow Pattern (Pfp) Showing Linear Pigmentation Along The Sulci Of The Skin Markings.

Uniform pigment may also be called ‘ homogeneous ’ (benign), and an irregular pattern may be called ‘ heterogenous ’ (atypical or malignant). Web parallel ridge pattern (furrows remain relatively hypopigmented) asymmetrical structure and colours; Web benign dermoscopy pattern [1] [2] parallel furrow pattern. And they may be relatively featureless.

The Furrows Are Relatively Hypopogmented.

Web acral melanocytic nevus is characterized by a parallel furrow pattern, whereas acral melanoma has a parallel ridge pattern. The fibrillar pattern appears more likely in lesions on weight bearing sites, and the lattice pattern on the arch of the foot. Dermoscopy of acral lentiginous melanoma Genetic alterations are also different between the two types of lesion.

Lines In Furrows Or On Ridges.

Web symmetrical pigment pattern is typical of benign skin lesions. Lines + dots, lines + circles, lines +. Linear pigmentation, predominantly localized to the furrows. Diffuse, scattered, central or peripheral.
