Melanonychia striata longitudinalis. incident light microscopy: Melanonychia striata through melanocytic nevus on the index finger in a 19-year-old woman. fine-grained longitudinal brown pigmentation below the nail plate. normal nail fold capillaries. distinct pigmentation of the cuticles.

Splinter hemorrhage: Reflected light microscopic image with a few days old splinter hemorrhage.

DD: Nail hematoma - here Melanonychia longitudinalis: Typical finding of a melanocytic pigmentation of the nail. Melanon grows in stripes, starting at the site of pigment formation (here the nail root is not visible) to the front. This finding is not observed in a nail hematoma. Note: the nail matrix shows a dark discoloration at the front edge of the cut (pigment is embedded in the nail matrix).

Differential diagnosis of discoloration of the nail: Melanocytic neoplasms of the nail matrix always lead to longitudinal striation of the nail plate.

Splinter hemorrhage: Fresh splinter hemorrhage in previously known progressive systemic scleroderma.

Melanonychia striata longitudinalis (course): Initial findings in 2006, control findings 3 years later; the brown longitudinal stripe, persisting since about 2004, has almost completely receded within a period of 3 years except for a discrete residual pigmentation (arrow).

Nail hematoma: " growing out" nail hematoma, an important differential diagnosis to subungual malignant melanoma.

Hutchinson's sign in malignant acrolentiginous melanoma.

Hematoma, nail hematoma: growing nail hematoma . left initial situation, right 8 weeks later. note: the nail matrix shows no discoloration at the cutting edge (marked by arrows)!

Melanonychia striata longitudinalis.

Nail hematoma: direct comparison of the outgrowing nail hematoma. Lower left after 8 weeks. On the right the reflected light microscopic images.

Melanonychia longitudinalis: stripy (melanotic) nail pigmentation caused by a (still benign) pigment nevus localized in the (not visible) nail matrix. The anterior incision edge of the nail plate is pigment-bearing (marked with an arrow). An initial malignant melanoma must be excluded.

Onychogrypose: 10-nail onychogrypose in cases of perennial erythrodermia of unknown etiology.

Pincer-nails: chronic contact allergic dermatitis with continuous formation of pincer nails, which are slightly painful on firm pressure.

Pseudo-Hutchinson, sign (hematoma). hemosiderotic pigmentation of the nail fold. age-related nail (longitudinal stripes) with fine spiltter hemorrhages.

Nail hematomas: traumatic subungal hematomas after jogging.

Melanonychia: Longitudinally over the nail plate running brown-black discoloration (pigmentation).

Onychodystrophy. Traumatic onychodystrophy with splinter hemorrhage.

Melanonychia longitudinalis: Wide discrete brown longitudinal discoloration of the thumbnail; the so-called Hutchionson sign (pigmentation of the nail fold in extension of the melanonychia strip) not detectable.

Splinter hemorrhage: older nail hematoma with peripheral splinter hemorrhages.

Onychodystrophy. Traumatic onychodystrophy with shrapnel bleeding.

Differential diagnosis of "nail hematoma": All melanocytic neoplasms of the nail matrix lead to striped pigmentation of the nail plate.

Melanoma, malignant, acrolentiginous, subungual and paraungual, black pigmented tumor in the fingernail area, advanced stage with destruction of the nail.

Mlelanom malignes acrolentiginous: Subungual malignant melanoma. Characteristic is the stripy growth through the entire length of the nail. The arrow marks the so-called Hutchinson sign.
