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).

Erythrasma: sharply defined, extensive, non-itching brownish discoloration in the armpit area.

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)

Livedo racemosa : irregular, bizarre non-closed circle segments, as pioneering morphological indicators of livedo racemosa, and cholesterol embolism occurred in this 73-year-old passon smoker.

Lentigo maligna: 71-year-old patient, more than five years old, first light brown, then darkened, symptom-free, 1.4 x 0.8 cm, light brown to black-brown spot in actinically stressed skin.

Acrocyanosis, livid discoloration of the lower extremity, here with pronounced onychomycosis.

dermatomyositis: reflected light microscopy. hyperkeratotic nail folds. pathologically enlarged and torqued capillaries. older bleeding into the nail fold.

Nevus, melanocytic, halo-nevus. solitary, erythematous, approx. 2 x 3 mm large, flat raised papule, surrounded by an oval, blurred, whitish yard.

Urticaria pigmentosa/progression: patient as before, 10 years later. in the meantime almost extensive infestation due to confluence of the flock. lbaortechnical indications for systemic infestation.

Amiodarone hyperpigmentation: cyanosis-likeamiodarone hyperpigmentation after long-term application of the preparation due to tachyarrhythmia.

Pityriasis versicolor alba: irregularly distributed, symptomless, bright spots, which in places have merged to form larger areas, appearing after repeated exposure to sunlight.

Airborne Contact Dermatitis: Retroauricular infection: This pattern distinguishes ACD from photoallergic eczema, where the "shadow area of the auricle" remains free.

Mononuleosis, infectious. generalized (almost universal) macular exanthema.

Toxic epidermal necrolysis: incipient extensive necrolytic detachment of the skin.

Lentigo maligna. Irregularly limited and colored pigment spot on the face.

Hypomelanosis guttata idiopathica: Multiple, chronic, for years increasing, disseminated, mainly at the light exposed areas, preferably localized on the stretching side, 0.2-0.4 cm large, round, symptomless, white, slightly rough spots.

Pityriasis versicolor: Large and small, slightly scaly, only occasionally slightly itchy, bright, bizarrely shaped spots (Pityriasis versicolor alba).

Light ageing of the skin: spotty skin with small hyperpigmentations (solar lentigines) and actinic keratosis.

acrocyanosis: typical picture of the red, cold foot in a 42-year-old chain smoker. variable course. erythema not painful. occurs at an ambient temperature of 20ºC and less. also in stressful situations

Dermatomyositis, malignoma-associated erythema in the area of the distal back of the hand and the sides of the fingers (= Gottron-signs) in a 67-year-old patient with bronchial carcinoma.

Dermatitis perioralis. perioral localized itchy, follicular, red papules, pustules and spots.

Livedovasculopathy: changes in the sole of the foot (rather rare localization)
