Dermoscopy of Actinic Keratosis: Is There a True Differentiation between Non-Pigmented and Pigmented Lesions?

Dermoscopic features of actinic keratosis (AK) have been widely studied, but there is still little evidence for their diagnostic accuracy. Our study investigates whether established dermoscopic criteria are reliable predictors in differentiating non-pigmented actinic keratosis (NPAK) from pigmented actinic keratosis (PAK). For this purpose, dermoscopic images of 83 clinically diagnosed AK (45 NPAK, 38PAK) were examined, and the sensitivity (Se), specificity (Sp), positive predictive value (PPV), and negative predictive value (NPV) were assessed.

Actinic Keratoses (AK): An Exploratory Questionnaire-Based Study of Patients' Illness Perceptions.

Background: Decreased illness perception among actinic keratoses (AK) patients is a major barrier to the effective management of AK.

Objective: We aimed to investigate patients' illness and treatment perceptions, their correlation to demographics and AK/skin cancer history, and secondarily the influence of these perspectives on treatment and sunscreen use.

Materials And Methods: Participants completed questionnaires based on the Brief Illness Perception Questionnaire and statistical analysis was performed.

The Effectiveness of Cryosurgery Combined with Curettage and Electrodessication in the Treatment of Keratoacanthoma: A Retrospective Analysis of 90 Cases.

Background: There are several treatment options for keratoacanthoma (KA). However, there are limited data available on the use of cryosurgery.

Objective: To evaluate the effectiveness and safety of a combination treatment for KA and to evaluate the cosmetic outcome.
