Nevus sebaceus Bilder

Sebaceous nevus: 25-year-old man; the reddish-brownish plaque, interspersed with whitish papules, was completely painless since birth; the excision was performed without complications and without spindle; a sebaceous nevus could be histologically confirmed.

Naevus sebaceus: Hairless spot (plaque) existing since birth in the capillitium of a 4-year-old boy with progressive yellow coloration and increasing thickness growth in the last months.

Naevus sebaceus: 1.8 x 3.2 cm in size, existing since birth, slightly raised, slightly increasing, skin-coloured plaque on the right thigh of a 3-month-old girl; numerous telangiectasias are conspicuous.

Sebaceous nevus: clinical aspect of a sebaceous nevus in a few-month-old infant; only the slight plaque-like elevation of the hairless area indicates the actual diagnosis.

Naevus sebaceus:Hairless, completely symptomless, verrucous plaque in the capillitium of a 25-year-old man, existingsincebirth; in recent years progressive verrucous growth.

Naevus sebaceus: Already at birth a completely symptomless, bizarrely configured, slightly red, waxy, always hairless spot or a corresponding plaque appeared in the neck area. The surface is slightly verrucous and irritated by excoriation. Since childhood surface growth analogous to body growth.

Naevus sebaceus: hairless plaque in the capillitium of a 14-year-old girl, existing since birth; progressive yellow/brown coloration in recent years.

sebaceous nevus: bizarrely configured, sharply bordered to the healthy skin, asymptomatic, hairless, relatively soft, verrucous plaque on the capillitium of a 28-year-old man. Before puberty only a hairless reddish-brown spot is noticeable. For several months development of brownish verrucous parts as well as two reddish papillomatous tumors (see upper parts of the nevus). Histological diagnosis of the proximal tumor: basal cell carcinoma.

Nevu sebaceus in the course: irregularly configured yellow plaque; above finding at the age of 8 years; below 3 years later.

Naevus sebaceus: chronically inpatient, solitary, approx. 4.0 x 2.0 cm, sharply defined, oily shiny, sour, orange-coloured, consistency increased, flatly elevated, symptomless plaque on the capillitium of a 35 years old patient, existing since birth. Within the skin change, at the lower right edge, a solitary bright round papule is visible.

Sebaceous nevus: Formation of a pigmented hidradenoma within the clearly defined, hairless sebaceous nevus.

sebaceous nevus: Development of different tumor formations in a sebaceous nevus in a 45-year-old patient. In addition to a skin-colored, very rough area with a large basal cell carcinoma, formation of a solid hidradenoma (pigmented tumor on the lower left side). For therapy, the entire hamartoma was excised with a safety margin of 0.5 cm.

Naevus sebaceus: congenital, initially unnoticed, bumped, red hairless area; for several months formation of a painless, repeatedly bleeding node (arrow mark) Dg.: Naevus sebaceus with formation of a solid basal cell carcinoma.

Sebaceous nevus: 60-year-old male. Known to be present since childhood. Wife wanted removal.

Naevus sebaceus: Close-up; findings known since childhood.

nevus sebaceus: reticular-acanthotic surface epithelium. multicenter development of a basal cell carcinoma. in the center of the preparation, deeply dermal situated, cystically dilated, immature apocrine glandular complexes. in the left third of the picture (center) incision of a small dystrophic hair follicle. otherwise hair follicles are typically missing. on the right side outside of the hamartoma mature hair follicle.

Nevus sebaceus: Detail enlargement: Basal cell carcinoma with typical, artificial cleft formation between tumor stroma and tumor parenchyma; strong dermal fibrosis; focally thinning round cell infiltrates.

Sebaceous nevus: A cluster of malformed hair follicles with ampoule-like dilated ducts; the surface epithelium is irregularly acanthotic.

nevus sebaceus. irregular acanthosis of the surface epithelium. in the upper and middle dermis numerous immature sebaceous gland complexes. on the right side a convolute sebaceous gland which is arranged in a mantle-like manner around a dilated infundibulum. no evidence of hairs. in the middle of the picture a dilated apocrine sweat gland duct.
