Actinic keratosis (AK) is a keratinocytic neoplasm that typically develops on sun‐damaged skin of elderly individuals. Only a few reports so far have described the dermoscopic diagnostic features of AK, mainly focusing on facial non‐pigmented AKs. A typical feature of facial non‐pigmented AK is a composite pattern named “strawberry pattern”, characterized by a background erythema/red pseudonetwork consisting of unfocused, large vessels located between the hair follicles, associated with…

Pigmented Actinic Keratosis: Case Report and Review of an Uncommon Actinic Keratosis Variant that can Mimic Melanoma
TLDR
A 54-year-old man who presented with a dark lesion on his nasal tip is described; biopsy of the lesion revealed a pigmented actinic keratosis that was treated with cryotherapy using liquid nitrogen.
Dermatoscopy of facial non‐pigmented actinic keratosis regarding to grades of the lesions
TLDR
This study aimed to examine dermatoscopic findings for patients thought to have non-pigmented facial AK and the relationship between dermoscopic findings and the clinical grades of AK lesions.
Dermoscopy of Pigmented Actinic Keratosis of the Face: A Study of 232 Cases.
Diagnosis of actinic keratosis by dermatoscopy
TLDR
Actinic keratosis has specific characteristics in treatment research, which helps to differentiate it from other benign and malignant tumors of the skin, and to diagnose it in its earliest stages without resorting to invasive procedures.

Dermoscopy in Pigmented Squamous Cell Carcinoma
TLDR
P pigmented SCC can present dermoscopic features typical of melanocytic lesions, such as radial streaks, globules, and homogeneous blue pigmentation, and can lead dermatologists to diagnostic errors.

Dermoscopic characteristics of nodular squamous cell carcinoma and keratoacanthoma
TLDR
Hemorrhage, keratinization and vascular features (glomerular, hairpin and linear irregular morphologies) are useful in diagnosing both nodular SCC and KA.

TLDR
The dermoscopic characteristics of a lesion that presents features of regressing seborrheic keratosis in LK are communicated to improve the diagnostic accuracy of pigmented skin lesions.

Dermoscopy for early detection of facial lentigo maligna
TLDR
Four cases of lentigo maligna of the face are reported whose identification depended on dermoscopic examination which was performed routinely on all facial lesions, as the lesions did not show ABCD clinical criteria for malignancy.

TLDR
A robust surface microscopy method is described that allows the diagnosis of pigmented BCCs from invasive melanomas and benign pigmented skin lesions.

Vascular structures in skin tumors: a dermoscopy study.
TLDR
Different morphologic types of vessels are associated with different melanocytic or nonmelanocytic skin tumors, and the recognition of distinctive vascular structures may be helpful for diagnostic purposes, especially when the classic pigmented dermoscopic structures are lacking.
Dermoscopy of pigmented skin lesions: results of a consensus meeting via the Internet.
TLDR
The virtual Consensus Net Meeting on Dermoscopy represents a valid tool for better standardization of the dermoscopic terminology and, moreover, opens up a new territory for diagnosing and managing pigmented skin lesions.
