BACKGROUND The similarity between clinical pictures of pigmented actinic keratosis (PAK) and lentigo maligna (LM) is well known. [] Key MethodMETHODS Eighty-nine FPSL were evaluated with conventional dermatoscopy.
Dermatoscopy of flat pigmented facial lesions
The diagnosis of flat pigmented lesions on the face is challenging because of the morphologic overlap of biologically different lesions and the unknown significance of dermatoscopic patterns.
Dermoscopic clues to differentiate facial lentigo maligna from pigmented actinic keratosis
Dermoscopy is limited in differentiating accurately between pigmented lentigo maligna (LM) and pigmented actinic keratosis (PAK). This might be related to the fact that most studies have focused on
This case report is highlighting the issue of anatomoclinical confrontation between a clinically suspected melanoma and a pathologically confirmed solar lentigo and seborrheic keratosis.
The value of reflectance confocal microscopy in diagnosis of flat pigmented facial lesions: a prospective study
Flat pigmented facial lesions are difficult to diagnose even with dermatoscopy. It is controversial how additional information obtained by in vivo reflectance confocal microscopy (RCM) impacts the

The clinical and dermatoscopic appearance of pigmented intraepidermal carcinoma is characterized by dermatoscopic dots and structureless areas, including dots in linear arrangement and by coiled vessels.
The importance of gray color as a dermoscopic clue in facial pigmented lesion evaluation: a case report
This small study aimed at determining the role of vaccination in the development of central giant cell granuloma is likely to have important implications for future research on this topic.
Dermoscopy of Actinic Keratosis, Bowen’s Disease and Squamous Carcinoma
The dermoscopic features of actinic keratosis, Bowen’s disease and squamous carcinoma were reviewed and the differential diagnosis was discussed.
Actinic Keratosis and Non-Invasive Diagnostic Techniques: An Update
Dermoscopy, confocal laser microscopy and optical coherence tomography could help clinicians in diagnosis ofinic keratosis.
Dermatoscopia das lesões pigmentadas na face: um desafio diagnóstico
These morphological parameters are discussed in light of the dermoscopic analysis of the commonalities between lentigo maligna and pigmented actinic keratosis, also touching upon the aspects already described for the diagnosis of pigmented acting keratoses.
Rosettes in actinic keratosis and squamous cell carcinoma: distribution, association to other dermoscopic signs and description of the rosette pattern
Rosettes, a dermoscopic structure characterized by four white points arranged as a 4‐leaf clover, supports the dermoscopic diagnosis of actinic keratosis (AK) or squamous cell carcinoma (SCC).


Dermatoscopy of pigmented actinic keratosis – A striking similarity to lentigo maligna
Pigmented actinic keratosis resembles lentigo maligna clinically and histopathologically in some cases and is associated with atypical wirkus in some patients.
[Pigmented actinic keratoses].
Histologically, in addition to characteristic findings of solar keratoses, melanin can be found within the lower epidermis and within melanophages in the upper dermis (incontinence of pigment).
[Spreading pigmented actinic keratosis--diagnosis and therapy].
A case of spreading pigmented actinic keratosis in a 61-year-old patient is reported, with characteristic features of spreading growth and a diameter greater than 1.5 cm.
Spreading pigmented actinic keratoses
The clinical and histological features of ten pigmented keratoses arising on the face are described, which had been spreading centrifugally and had progressed to become pigmented squamous cell carcinomas.

Most authors consider LPLK as an heterogeneous spectrum of intraepithelial epidermal or melanocytic lesions, mainly pigmented, involuting by inflammatory regression.

Dermoscopic features of actinic keratosis
Recognizing specific dermoscopic features of AK can be useful in guiding the clinician in the differential diagnosis of AK with melanocytic skin lesions such as LM and non‐melanocytic lesions, and Histopathologic examination should be performed whenever clinical and/or dermosCopic differential diagnosis is inconclusive.
