TL;DR: The parallel ridge pattern (PRP) is considered the dermoscopic hallmark of acral melanoma (AM), but it was recently shown that approximately one‐third of AMs do not display a PRP dermoscopically, rendering their detection more troublesome.

Palmar and plantar melanomas differ for sex prevalence and tumor thickness but not for dermoscopic patterns.
Aimilios Lallas,Dimitrios Sgouros,Iris Zalaudek,Masaru Tanaka,Toshiaki Saida,Luc Thomas,Harald Kittler,Ken Kobayashi,Hiroshi Koga,A. Phan,Caterina Longo,Elvira Moscarella,Alexandros Katoulis,Giuseppe Argenziano +13 more
TL;DR: Plantar and palmar AMs show sex-related and thickness-related differences, but do not differ with respect to their dermoscopic features, according to the localization on palms or soles.

Oblique view dermoscopy changes regular fibrillar pattern into parallel furrow pattern.
TL;DR: It is proved that the fibrillar pattern is directly caused by an oblique arrangement of melanin pigment columns in the slanting stratum corneum with a three-dimensional reconstruction method using specimens of acral nevi of parallel furrow or fibrillsar patterns.
Detection of Iron Deposition in Dermal Fibrocytes Is a Useful Tool for Histologic Diagnosis of Nephrogenic Systemic Fibrosis
Julia Miyamoto,Akiko Tanikawa,Atsuyuki Igarashi,Hiroshi Hataya,Ken Kobayashi,Masahiro Ikegami,Akihiro Sotome,Yayoi Nagai,Kaori Kameyama,Akira Ishiko +9 more
TL;DR: Positive iron staining may be specific to NSF and can be a useful tool for NSF diagnosis, and the amount of iron deposition seemed to have no correlation with the degree of fibrosis or duration of the skin lesions but correlated with apparent history of the use of gadolinium-based contrast agents.

TL;DR: Over the 10-year study period, accuracy in melanoma detection improved only in specialized clinics maybe because of a larger use of new diagnostic techniques such as dermatoscopy.
