Lentigo maligna (LM), a melanoma in situ, is a fairly common melanocytic lesion that usually develops on the chronically sun-exposed skin of the head and neck of Caucasians. It occurs mostly in people older than 40 years, with an incidence rate that increases with age and peaks in the seventh and eighth decades of life.

Summary Lentigo maligna (Hutchinson's melanotic freckle) has an amelanotic variant that may not be as rare as the literature suggests. None of the published cases were suspected clinically. In Australia we should suspect any slowly expanding depigmented or pink lesion on exposed areas, especially if it develops a nodule.

A 68-year-old woman had a pigmented lentigo maligna lesion excised from her left arm. During a seven-year follow-up period, the excision site gradually evolved into a hypopigmented macule with irregular areas of mild erythema. The clinical impression was neurodermatitis, but a biopsy specimen revealed lentigo maligna without melanin pigmentation.

Lentigo maligna and lentigo maligna melanoma
Journal of the American Academy of Dermatology, 1995Lentigo 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.

Reticulated Black Solar Lentigo (`Ink Spot' Lentigo)
Archives of Dermatology, 1992Pigmented lesions that are black and have an irregular outline are often considered suspicious for melanoma; however, these features may be seen in benign lesions. The reticulated black solar lentigo is such a lesion and is described in a clinicopathologic study of nine lesions in eight patients.The "ink spot" lentigo is distinguished clinically by its

Tt is usual for lentigo maligna to present a variegated pigmented macule in which the degree of coloration and configuration are continually changing. 1 I report a case in which an erythematous macule developed into an amelanotic melanoma. Report of a Case A 66-year-old woman was seen in 1977 because of a ten-year history of an erythematous lesion on

Lentigo maligna melanoma is a malignant melanoma with a recognizable clinical pattern. It is a slow‐growing, pigmented tumor evolving from a premalignant lesion on the exposed cutaneous surface of an elderly patient. Histologically, it is marked by pleomorphism of melanocytes with evidence of invasion.A case is presented demonstrating the features of ...

Treatment of Lentigo Maligna and Lentigo Maligna Melanoma
The Journal of Dermatologic Surgery and Oncology, 1979The results of treatment of 42 cases of lentigo maligna and 16 of lentigo maligna melanoma at the New York University Medical Center were reviewed. The recurrence rate after surgical excision of 22 lesions of lentigo maligna was 9% (2/22), but after treatment of 20 such lesions with destructive techniques (X rays, curettageelectrodesiccation ...

Recurrent lentigo maligna as amelanotic lentigo maligna melanoma
Journal of the European Academy of Dermatology and Venereology, 2002AbstractAmelanotic lentigo maligna and lentigo maligna melanoma are extremely rare tumours. Even rarer is a recurrent amelanotic lentigo maligna or amelanotic lentigo maligna melanoma at the site of a previously removed pigmented lentigo maligna. We describe two cases of recurrent amelanotic lentigo maligna melanoma manifesting as erythematous plaques ...

A lentigo is a small pigmented macule with a sharply circumscribed border. There are multiple clinical and etiologic forms. Lentigines are often initially identified shortly after birth, although they may appear later in childhood. Certain varieties are associated with systemic abnormalities.
