Dermatoscopy of Lentigo Maligna

Dermoscopy of pigmented skin lesions

“…It is due to a homogeneous pigmentation which is interrupted by the surface openings of the adnexal structures. 11,66,73 The differential diagnosis of a pseudonetwork is solar lentigo, seborrheic keratosis, lentigo simplex, melanoma in situ, lichen planuselike keratosis, and pigmented actinic keratosis. 11,66,73 These lesions are often difficult to distinguish dermoscopically.…”

“…11,66,73 The differential diagnosis of a pseudonetwork is solar lentigo, seborrheic keratosis, lentigo simplex, melanoma in situ, lichen planuselike keratosis, and pigmented actinic keratosis. 11,66,73 These lesions are often difficult to distinguish dermoscopically. However, when there are multiple colors and a broadened, thickened, and irregular ''pseudonetwork,'' melanoma is often the diagnosis suggested.…”

“…Other, more specific characteristics include an ''annular granular'' or ''rhomboidal pattern.'' 11,66,73 Revised pattern analysis…”

Spreading pigmented actinic keratosis: A review

“…19,[21][22][23][24] The slategray dots and globules detected in SPAK have a more uniform size and a more regular, symmetric distribution than those found in MIS (lentigo maligna type). In addition, hypopigmented follicular openings surrounded by a rim of hyperpigmentation favors the diagnosis of MIS (lentigo maligna type).…”

Management of lentigo maligna and lentigo maligna melanoma: Seminars in surgical oncology

“…The differential diagnosis will include lentigo simplex, lenticular seborrheic keratosis, pigmented actinic keratosis, and pigmented basal cell carcinoma. Additional clinical information about suspicious pigmented lesions can be obtained by dermatoscopy [20] and epiluminescence microscopy [21] and advanced techniques such as confocal laser microscopy [22].…”
