    Acta Dermatovenerol Croat 2019; 27(2):129-130Monteagudo-Sánchez B, Luiña-Méndez L, Mosquera-Fernández A
  • Dear Editor, We report a case of a patient admitted to our Department presenting a typical digital myxoid cyst. A 54-year-old man was referred by his general practitioner to the Department of Dermatology at our hospital due to the presence of an asymptomatic lesion on the third right toe. Physical examination revealed a rounded, red-bluish lesion in the eponychium less than 0.5 cm in diameter wit…
  • Curling Cuticles of the Great Toenails: A Case Report of Eponychogryphosis. [Case Reports]
    Cureus 2019; 11(1):e3959Cohen PR
  • The cuticle, also referred to as the eponychium, creates a seal between the proximal nail fold and the nail plate. It is derived from both the ventral and dorsal portions of the proximal nail fold. In addition to its principle function as a barrier preventing allergens, irritants and pathogens from entering the nail cul-de-sac, the cuticle can play a role as a model for evaluating the etiology an…

    Am J Dermatopathol 2018; 40(3):180-184Perrin C, Michiels JF, … Ambrosetti D
  • Previous studies of the density of melanocytes in the normal nail bed have had conflicting results. This is unfortunate because knowing the normal values might help the difficult distinction between a benign subungual melanotic macule and an early melanoma in situ. Five specimens of normal nail unit were analyzed. On hematoxylin and eosin-stained sections the melanocytes were undetectable. We def…

    StatPearls Publishing: Treasure Island (FL) Pencle Fabio J. FJ Waseem Muhammad M Lincoln Medical Center / SGU BOOK
  • The fingertip is the most distal portion of the finger providing the tactile and sensory functions that are then relayed to the brain. It is anatomically defined as the portion of finger distal to the insertion of the flexor digitorum superficialis and extensor tendons on the distal phalanx, or the interphalangeal joint when referring to the thumb. The neurovascular supply of the fingertip is via…
  • Anatomy of the nail unit and the nail biopsy. [Journal Article]
    Semin Cutan Med Surg 2015; 34(2):95-100Haneke E
  • The nail unit is the largest and a rather complex skin appendage. It is located on the dorsal aspect of the tips of fingers and toes and has important protective and sensory functions. Development begins in utero between weeks 7 and 8 and is fully formed at birth. For its correct development, a great number of signals are necessary. Anatomically, it consists of 4 epithelial components: the matrix…
