Furrow Pattern Acral Nevus

The parallel furrow pattern is regarded as the prototype of the three major dermoscopic patterns of acral melanocytic nevus. A and b, pigmented lesion on the left plantar surface. Dermoscopy contributes to the early diagnosis of melanoma and the reduction of unnecessary skin biopsy [1], [2]. 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. However, they preferentially transfer melanin to the keratinocytes associated with the furrow.

A and b, pigmented lesion on the left plantar surface. Here, the melanocytic pigmentation is visible on the parallel sulci of the skin marking. The parallel furrow pattern has pigment in the furrows (sulci) of the foot or hand ( fig. Lesions with a parallel furrow pattern and acral nevi that grow and become an elongated shape along the furrow are often benign. Fig 1 a and b, pigmented lesion on the left plantar surface.

Web the furrow ink test is a quick and easy method to facilitate the correct identification of furrows and ridges on volar skin and facilitates dermoscopic diagnosis of pigmented lesions in acral sites. Web there are three distinct patterns of acquired acral nevi that signify benignity. Dermoscopy contributes to the early diagnosis of melanoma and the reduction of unnecessary skin biopsy [1], [2]. Web the images displayed on this article illustrate the pattern of parallel ridges in one case of racial melanosis and another case of congenital melanocytic nevus, phototypes v and iv respectively, without obliteration of the acrosyringia, which are the superficial openings of the eccrine glands on the epidermis ( figures 1, 2, 3 and 4 ). Fig 1 a and b, pigmented lesion on the left plantar surface.

Web acral melanocytic nevi have three major dermoscopic patterns: Web the parallel furrow pattern most often appears in naevi on the side of the foot. Pigmentation on the ridges of the surface skin markings is detected in early acral melanoma, whereas pigmentation along the furrows of the skin markings is seen in acral nevus. In benign acral nevus, the following four dermoscopic patterns can be seen: 5 peas in a pod pattern (parallel furrow + globules on ridges) (congenital nevi) The parallel furrow pattern is regarded as the prototype of the three major dermoscopic patterns of acral melanocytic nevus. Web pigmentation pattern on dermoscopy is completely opposite between early acral melanoma and acral nevus; Web the furrow ink test is a quick and easy method to facilitate the correct identification of furrows and ridges on volar skin and facilitates dermoscopic diagnosis of pigmented lesions in acral sites. A and b, pigmented lesion on the left plantar surface. Web the images displayed on this article illustrate the pattern of parallel ridges in one case of racial melanosis and another case of congenital melanocytic nevus, phototypes v and iv respectively, without obliteration of the acrosyringia, which are the superficial openings of the eccrine glands on the epidermis ( figures 1, 2, 3 and 4 ). Fig 1 a and b, pigmented lesion on the left plantar surface. Web recentresearch has revealed that acral nevi may be located at he tips of rete ridge sassociated with the crista intermedia and limitans; Web pigmentation on the ridges of the surface skin markings is characteristic of early acral melanoma. The lattice pattern is a variant of parallel furrow with perpendicular pigmented lines connecting pigment in the furrows. Here, the melanocytic pigmentation is visible on the parallel sulci of the skin marking.

These Methods Have Been Discussed Here Based Upon A Series Of Literature Reviews, The Authors’ Own Experience And, Also, Iconography.

Web pigmentation pattern on dermoscopy is completely opposite between early acral melanoma and acral nevus; The fibrillar pattern appears more likely in lesions on weight bearing sites, and the lattice pattern on the arch of the foot. Web the parallel furrow pattern most often appears in naevi on the side of the foot. Web pigmentation on the ridges of the surface skin markings is characteristic of early acral melanoma.

Web Acral Melanocytic Nevi Have Three Major Dermoscopic Patterns:

The parallel furrow pattern is regarded as the prototype of the three major dermoscopic patterns of acral melanocytic nevus. The parallel furrow pattern has pigment in the furrows (sulci) of the foot or hand ( fig. Web the confirmation of benign and melanocytic lesions of acral volar skin, on the other hand, is more accurate when using the ink furrow test. Web dermoscopic images were collected from the 48 patients of acral lentiginous melanoma with ridge pattern melanomas and 62 patients of benign nevus on the acral area with furrow pattern, from january 2013 to march 2014 at the severance hospital at the yonsei university health system, seoul, korea.

Here, The Melanocytic Pigmentation Is Visible On The Parallel Sulci Of The Skin Marking.

Web there are three distinct patterns of acquired acral nevi that signify benignity. The lattice pattern is a variant of parallel furrow with perpendicular pigmented lines connecting pigment in the furrows. Here, the melanocytic pigmentation follow and crisscross the skin markings. 3 fibrillar pattern (soles only) 4 homogenous pattern;

Dermoscopy Is A Helpful Tool That Can Assist Experienced Users In Differentiating Between Melanoma And Benign Melanocytic Nevi.

The second, by lallas et al., uses six dermatoscopic variables to assess the likelihood of alm under the acronym. Fig 1 a and b, pigmented lesion on the left plantar surface. In benign acral nevus, the following four dermoscopic patterns can be seen: A and b, pigmented lesion on the left plantar surface.
