In vivo confocal microscopy can noninvasively image thin en face sections within living intact human tissue with high resolution and contrast. This evolving technique may provide clinicians with tools to help detect lentigo maligna lesion progression in vivo and may be important in defining tumor margins, thus providing a more definitive surgical eradication of lentigo maligna and malignant mel...

BACKGROUND The dermatoscopic features of facial lentigo maligna (LM), facial lentigo maligna melanoma (LMM) and acral lentiginous melanoma (ALM) have been well described. This is the first description of the dermatoscopic appearance of a clinical series of cutaneous non-facial non-acral lentiginous growth pattern melanomas. OBJECTIVE To describe the dermatoscopic features of a series of cutan...

On the face, the important differential diagnosis of pigmented skin lesion is between lentigo maligna, lentigo maligna melanoma, and flat seborrheic keratosis or lentigo seniles (synonymous with flat seborrheic keratosis in our terminology). In this article, we have summarized our experience in this field. Numerous examples for the criteria mentioned are given in the second edition of the Color...

Lentigo maligna (LM) is a pigmented lesion that occurs on the sun-exposed skin, particularly the head and neck areas, of an older patient. The lesion increases in size and at some point, often many years after its onset, may become lentigo maligna melanoma (LMM). For this reason, most authors consider LM a form of melanoma in situ. Treatment includes surgical or destructive modalities; the pref...

Senile lentigo or age spots are hyperpigmented macules of skin that occur in irregular shapes, appearing most commonly in the sun-exposed areas of the skin such as on the face and back of the hands. Senile lentigo is a common component of photoaged skin and is seen most commonly after the age of 50. There are many disscusions on whether senile lentigo represents a melanoma precursor, namely len...

Lentigo maligna has an extensive and neoplastic character. It typically progresses slowly and may eventually develop into an invasive melanoma, which is called lentigo maligna melanoma. Ocular melanoma is the second most common type of melanoma. The uvea is the most common site of origin of ocular melanomas, while conjunctival melanoma accounts for about 1-5% of cases. In this article, we descr...

OBJECTIVES To assess interobserver and intraobserver concordance for identifying positive and negative margins in staged excisions of lentigo maligna and lentigo maligna melanoma and to determine if control biopsy specimens are useful to improve concordance. DESIGN Retrospective, randomized interobserver and intraobserver comparison study of archived pathologic specimens. The study was conduc...

Thirty-eight cases of lentigo maligna and 22 cases of lentigo maligna melanoma, were reviewed in order to compare cure rates of various methods of treatment. Surgical excision resulted in the best cure rate (91%); destructive modalities were less successful (45%). All lesions treated with 5% 5-fluorouracil recurred.

BACKGROUND Lentigo malignant melanoma is a melanoma subtype of chronic sun-damaged skin in elderly Caucasians. Amelanotic variants of lentigo malignant are extremely rare. CASE PRESENTATION This is a case report of an 80-year-old male patient who presented with a non-pigmented exophytic tumour of his bald head. After complete surgical excision under the suspicion of squamous cell carcinoma, t...
