Dyskeratosis follicularis: densely packed brown-reddish papules, about 2-4 mm in size, which aggregate in the décolleté area; the present distribution pattern suggests a light provocation of the disease.
Lichen sclerosus extragenitaler: large-area lichen sclerosus of the mamma; diffuse, veil-like, only slightly increased sclerosis of the skin; not quite fresh large-area hematoma in lesioned skin. Remark: in the bradytrophic lesions of the LS, bleedings persist for an unusually long time, so that the persistent (gradually blackening hematoma) is the actual reason for a visit to the doctor.
Pemphigus erythematosus: for several years recurrent, symmetrical, little symptomatic, red, plaques with coarse lamellar scales located in the seborrheic zones.
Lupus erythematosus, subacute-cutaneous: progress photo; recurrent relapsing activities, here picture taken after a 6-year course of the disease; ANA+; anti-Ro Ak+.
Melanoma, malignant, superficially spreading. reflected light microscopy: Inhomogeneous, black-greyish-bluish pigmented, sharp but irregularly defined plaque with widened reticular ridges and irregular netting meshes. The outer line with streaky, bud-like extensions is characteristic of malignancy.
Dyskeratosis follicularis: Papules and dirty-brownish crusts of a zosteriform-striary dyskeratosis follicularis in the course of the blaschkolines in the upper abdomen and flanks in a 5-year-old girl.
Relapsing activity in chronic psoriasis: psoriasis known for a long time. 4 weeks (post-infection) of clear relapsing activity with small papules and plaques. Itching.
Circumscribed scleroderma. Atrophy of the right leg muscles, atrophy of the gluteal muscles on the right, shortening of the right leg (difference 2.0 cm) with consecutive secondary pelvic obliquity and scoliosis in a 19-year-old female patient. The right knee joint is massively restricted in its movement (extension/flexion 0/25/100).
Mycosis fungoides: tumor stage. 53-year-old man with multiple, disseminated, 1.0-5.0 cm large, in places also large-area, moderately itchy, clearly consistency increased, red, rough, confluent plaques.
