is usually harmless, but some may eventually develop into malignant melanomas, particularly if they're on the face
Guitera P Pellacani G, Crotty KA, et al: The impact of in vivo reflectance confocal microscopy on the diagnostic accuracy of lentigo
maligna and equivocal pigmented and nonpigmented macules of the face.
The effects of chronic sun exposure are more difficult to determine, but may be associated with lentigo
c) The gold-standard treatment for melanoma in situ and lentigo
maligna is surgical excision with the Mohs technique (18), because these kinds of lesions have no potential for metastatic spread (19).
They are not the precursors of melanoma or lentigo
maligna although these more threatening melanocytic lesions certainly do arise more frequently in sun-damaged skin than unexposed skin.
Thomas' Hospital, London, UK) offer an atlas on melanocytic pathology that presents information in a bullet format alongside photos and slides illustrating the pathology of lesions, including lentigo
, oral mucosa pigmented lesions, and conjunctival melanocytic lesions, for use in diagnosis.
Researchers examined two cases of the most common type of melanoma of the head and neck, lentigo
maligna (LM), a type of "melanoma-in- situ", the earliest stage of melanoma.
A "I SUSPECT you mean solar lentigo
spots, also known as liver spots.
By what name is the skin marking lentigo
Occasionally, these benign tumors need to be separated from verruca vulgaris (wart), solar lentigo
, squamous cell carcinoma, and melanoma, but separation is usually straightforward, relying on deeper levels cut into the block rather than on special studies.
maligna (LM) is a preinvasive lesion that occurs most commonly on the sun-exposed areas of the head and neck of elderly individuals.
One uncommon form is called lentigo
Some of the more common skin problems among the elderly include dry skin (which affects most people by age 70), seborrheic keratosis (age spots-sometimes precancerous) and actinic lentigo
(liver spots, or sun freckles).
Dort hastada solar lentigo

The most striking reproducible pattern is strong pan-nuclear expression of sAC in lentigo
maligna melanoma along with other melanomas exhibiting a lentiginous radial growth phase (ie, acral lentiginous and mucosal lentiginous melanomas).
