nail hematoma: blue-black discoloration of the big toe nail. sharp limitation distally. no continuous nail pigmentation (see also inlet)

haematoma, nail haematoma. nail alteration after slight crush trauma. striped, red and blue-black spots (splinter hemorrhages). since red and black shades are present at the same time, this finding speaks against a melanotic pigmentation.

Splinter hemorrhage.

Nail hematoma: since exactly 6 weeks existing (trauma reminding), sharply forward limited blue-black discoloration of the big toe nail with discoloration of the epinychium; the sharp, here diagonally running dividing line without distal stripe-shaped discoloration of the nail matrix excludes a malignant melanoma!

DD: Melanoma malignes acrolentiginous: here: complicating onychomycosis with bleeding due to mold infestation; the inlet points proximally, a normally colored nail area; no Hutchinson phenomenon.

Hematoma, nail hematoma: clearly limited nail discoloration in all directions, see next figure with comparison after 8 weeks.

Erythronychia, localized longitudinal detail magnified by reflected light microscopy; solitary, painless, red longitudinal striation of the nail plate with slight, V-shaped retraction and several splinter hemorrhages.

Nail hematoma: Apparently caused by repetitive trauma (probably triggered by a trauma from frontal trauma, e.g. during a football match), transverse bleeding, the growing nail area is normally stained.

Erythronychia, localized longitudinal. idiopathic, solitary, painless, red longitudinal striation of the nail plate with low-grade, V-shaped retraction and splinter hemorrhaging. The clinical picture is diagnostically conclusive.

half and half nail: zonal, sharply bordered white coloration of the proximal and brown coloration of the distal nail plate. slight acrocyanosis. no underlying disease remembered. known is a polyneuropathy

Illustration was kindly provided by Dr. med. H. Luther/Essen.

Melanonychia striata longitudinalis: approx. 0.2 cm wide, dark brown strip of the nail. nail fold very discreetly affected (see inlet). only 1 fingernail is affected. a clinical control (photo documentation) with measurement of the width of the pigment strip is recommended.

hematoma, nail hematoma. blue-blackish, sharply defined pigmentation (here of the big toe nail) due to a previous traumatic event. no distal stripy nail discoloration. the absence of distal stripy nail changes excludes the important differential diagnoses "subungual malignant melanoma" and "subungual melanocytic nevus".

Nail hematoma: sharply limited brownish discoloration of the nail; no streaky distal pigmentation of the nail (important differential diagnostic distinction to a malignant melanoma).

nail hematoma: deep black discoloration of the nail plate. discoloration of the cuticle. the distal edge of the nail is not discolored.

psoriasis vulgaris. psoriasis of the nails. subungual and ungual infestation, here with parakeratotic keratinization

Melanonychia striata longitudinalis (detailed picture): approx. 0.4 cm wide, dark brown strip of the nail; nail fold with distinct paraungual rim; especially malignant melanoma of the nail root.

Splinter hemorrhage. Reflected light microscopy

Nail hematoma: since exactly 6 weeks existing (trauma recallable), sharply forward limited blue-black discoloration of the big toe nail (marked by arrows and line) with discoloration of the epinychium (circle); arrow (right) indicates a streaky (still red) apparently fresher bleeding

Glomus tumor, frequent, discreet finding with blue-reddish, very pressure-painful discoloration of the fingernail.
