Om några förändringar inträffar bör ytterligare ett steg tas.
Feedback: Hudläkare kan jämföra bilder från dermoskopi av seborroiskt keratosdermatit under olika tidpunkter för att bedöma effektiviteten av behandlingen av seborroiskt keratoseksem och sedan avgöra om behandlingen behöver justeras eller inte.
Behandlingshjälpmedel: Vid behandling av seborroiskt keratosdermatit kan bilder tydligt och exakt visas genom dermoskopi av seborroiskt keratoseksem.

Diagnosis of Seborrheic Keratoses
History and physical examination alone
Diagnosis of seborrheic keratosis is clinical. Dermatoscope är ett litet handhållet upplyst medicinskt mikroskop som möjliggör en mer exakt och djupare bild av hudsjukdomar genom hög förstoring och ett kraftfullt bländfritt belysningssystem.
Dermatofibroma and an overview of other benign skin lesions are presented separately.

EPIDEMIOLOGY
SK is one of the most common, if not the most common, benign skin tumors occurring in adults and older individuals of all ethnicities without sex predilection.

INTRODUCTION
Seborrheic keratosis (SK) is a common benign skin neoplasm consisting of immature epidermal keratinocytes [1,2].
It is not intended to be medical advice or a substitute for the medical advice, diagnosis, or treatment of a health care provider based on the health care provider's examination and assessment of a patient's specific and unique circumstances. The lesions commonly occur in middle age and later and most often appear on the trunk or temples. De kan gradvis dyka upp på olika delar av kroppen, mestadels i ansiktet, nacken, bröstet eller ryggen.
Varför är det nödvändigt att använda en dermoskopi av seborroisk keratos dermatit?
Dermatoskop är en icke-invasiv teknik som gör det möjligt för hudläkare att noggrant undersöka seborroiskt keratosdermatit mer exakt och exakt.
Dermatoskop förstorar och ljusnar upp former och strukturer av lesioner. Seborroiskt keratosdermatit är en typ av godartad hudsjukdom som inte är cancerframkallande. 2025© UpToDate, Inc. and its affiliates and/or licensors.
The cause of seborrheic keratosis is unknown, but genetic mutations have been identified in certain types.
Därför kan hudläkare avlägsna seborroisk keratoss säkert och säkert av några estetiska skäl.
Det är viktigt att utveckla vanan att använda dermoskopi av seborroiskt keratosdermatit. read more

Blood vessels can be prominent in some seborrhoeic keratoses, tending to arise as tiny hairpin shaped capillaries surrounded by a halo within a lobule.

Identification of seborrhoeic keratoses by Chaos and Clues method
Seborrhoeic keratoses demonstrate "chaos" by modified pattern analysis, ie, they often have asymmetry of colour and structure on dermatoscopy — like pigmented skin cancers.
They usually have a stuck-on appearance and may have a verrucous, velvety, waxy, scaling, or crusted surface. Dermoscopy is very helpful in making a definitive diagnosis of seborrheic keratosis.
Treatment of Seborrheic Keratoses
Removal only if bothersome
Lesions are not premalignant and do not require treatment unless they are irritated, itchy, or cosmetically bothersome to the patient.
