Melanonychia striata Bilder

Melanonychia striata longitudinalis. initial findings in 2006. Completely asymptomatic longitudinal pigmentation of the nail plate, which has existed for about 2 years and has increased continuously.

Melanonychia striata longitudinalis.

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).

Melanonychia striata longitudinalis (initial findings): approx. 0.3 cm wide, light brown strip of the nail. nail fold not affected. only 1 fingernail is affected. a clinical control (photo documentation) with measurement of the width of the pigment strip is recommended.

Melanonychia striata longitudinalis (control finding 4 years later): approx. 0.4 cm wide, light brown, laterally blurred strip of the nail. Nail fold not affected. Both thumbnails are now affected. This course speaks against malignancy.

Melanonychia striata longitudinalis.

Melanonychia striata longitudinalis.

Melanonychia striata longitudinalis. solitary, chronically stationary, approx. 1.2 cm long, acral accentuated, linear, sharply defined, brown longitudinal stripe on the right thumb of a 6-year-old boy. No nail fold alteration so far.

Melanonychia striata longitudinalis: No pimentation of the perionychium = negative Hutchinson sign.

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.

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.

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

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.

Melanonychia striata longitudinalis. approx. 2 mm wide, light brown stripe in the region of the thumbnail in a 7-year-old boy. No involvement of the nail fold, no paraungual border. Currently harmless findings.

Melanonychia striata longitudinalis. 4 months" (realistic is a duration of years) of persistent brown longitudinal stripes on the fingers of the right hand in a 64-year-old Turkish man. Mainly Laugier-Hunziker-Baran syndrome. Malignancy was excluded.

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.

Melanonychia striata longitudinalis.

Melanonychia striata longitudinalis: completely asymptomatic brown-black longitudinal pigmentation of the nail plate, which has existed for about 2 years and has continuously increased in colour intensity.

Melanonychia striata longitudinalis: completelysymptomless brown-black longitudinal pigmentation of the nail plate. on frontal view the thickness of the pigment strip becomes visible. the white-crumbly structure of the nail indicates an additional nail mycosis.

Melanonychia striata with complicating onychomycosis

Melanonychia striata with complicating onychomycosis. White encircles the mycotic nail parts. Blue delimits the proximal line of infection.

Melanonychia striata: Discreet (harmrous) infestation of the thumbnails on both sides.

Melanonychia striata longitudinalis (1): Initial findings in 2009. Completely symptomless longitudinal pigmentation of the nail plate. Exists for 2 years. Continuous increase.

Melanonychia striata longitudinalis (2): control finding in 2016. widening of the longitudinal pigmentation of the nail plate. clear Hutchinson sign (pigmentation of the nail fold)

Melanonychia striata longitudinalis (2a): Control finding in 2016. detailed picture of the nail fold. clear Hutchinson sign (pigmentation of the nail fold).

Striped black coloration of the big toe nail. The finding is unchanged since > 1 year. Here striped onychomycosis due to mold infestation of the nail. Diagnostic evidence is the normally colored proximal stripe above the nail dyschromia (see explanatory figure and reflected light microscopy).

streaky black coloration of the big toe nail. the finding is unchanged since > 1 year. here streaky onychomycosis due to mold infestation of the nail. diagnostic evidence is the normally colored proximal strip (star) above the nail dyschromia. arrows mark the yellowish discolored, mycotic changes caused by a trichophyte.

streaky "black coloration" of the big toe nail. the finding has been unchanged for > 1 year. greenish marginal areas are detectable by incident light microscopy. this color tone speaks against a melanin-related coloration. diagnosis: streaky mold pizza infestation of the nail.

Differential diagnosis of melanonychia: In figure V the arrow points to the pigmentation of the nail fold (Hutchinson sign), which is important for the differential diagnosis.
