Lentigo maligna and malignant melanoma in situ, lentigo maligna type
Human Pathology, 1999Some authors have considered lentigo maligna to be an atypical melanocytic proliferation, whereas others have considered it to be melanoma in situ. We reviewed 50 cases of lentigo maligna. We have identified two subsets of lesions. The first has atypical melanocytic hyperplasia, which we postulate to be correctly designated lentigo maligna.

Amelanotic lentigo maligna melanoma
Journal of the American Academy of Dermatology, 1995Only five cases of the amelanotic variant of lentigo maligna melanoma of the face have been reported. We describe an additional four patients observed within the past 5 years, suggesting a much higher incidence of this variant than previously suspected.

Metastatic Lentigo Maligna Melanoma
The Journal of Dermatologic Surgery and Oncology, 1990Abstract. An elderly woman presented with an advanced and ultimately lethal lentigo maligna melanoma after ignoring a precursor lesion present for several decades. Lentigo maligna melanoma can be lethal in the elderly. Early detection and treatment are warranted.

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 ...

Treatment of Lentigo Maligna and Lentigo Maligna Melanoma
The Journal of Dermatologic Surgery and Oncology, 1980Thirty‐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.

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 ...

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.

Lentigo Maligna, Lentigo Maligna Melanoma In Situ and Lentigo Maligna Melanoma
2012The spectrum of severely atypical melanocytic proliferations in sun-damaged skin of the elderly ranges from a proliferation of scattered individual cells along the dermal epidermal junction (lentigo maligna), to a dense proliferation of tumor cells that replaces the epidermis with nesting, confluence and pagetoid spread (lentigo maligna melanoma in ...

Lentigo Maligna/Lentigo Maligna Melanoma: Current State of Diagnosis and Treatment
Dermatologic Surgery, 2006Lentigo maligna (LM) is a subtype of melanoma in situ that typically develops on sun-damaged skin. Presentation may be quite subtle and delayed diagnosis is common. Clinical margins are often ill defined. Histologic evaluation can be difficult due to the widespread atypical melanocytes that are present in the background of long-standing sun damage ...
