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.

Cryotherapy for lentigo maligna
Clinical and Experimental Dermatology, 1991Eleven patients, 10 with lentigo maligna (LM) and one with lentigo maligna melanoma (LMM), were treated with cryotherapy. The symptoms cleared in all patients except one with LM. There were recurrences in four patients and three cleared with further treatment.

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, 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 ...

SUMMARYLentigo maligna (LM) is the in situ phase of lentigo maligna melanoma (LMM) and, if left untreated, 30‐50% of cases will progress to LMM, which is now thought to behave as aggressively as any other melanoma. Literature on the of treatment of LM including conventional surgery, micrographic Mohs surgery, cryosurgery, radiotherapy ...

Estimated risk of progression of lentigo maligna to lentigo maligna melanoma
Melanoma Research, 2020Little is known about the risk of progression of lentigo maligna to lentigo maligna melanoma. We determine the annual risk of progression of lentigo maligna to lentigo maligna melanoma by analysing a prospective population-based survey of recently diagnosed anterior (visible in a mirror) head and neck lentigo malignas and lentigo maligna melanomas. Six

Lentigo Maligna and Lentigo Maligna Melanoma: Recognition and Treatment
Archives of Otolaryngology - Head and Neck Surgery, 1978Lentigo maligna is the preinvasive stage of lentigo maligna melanom, which is a specific type of cutaneous malignant melanom found almost exclusively in the head and neck area. The distinguishing features and the biological behavior of this disease are discussed.

Cryosurgery for lentigo maligna
Journal of the American Academy of Dermatology, 1994The need for treatment of lentigo maligna is related to the cosmetic benefits and to the potential for malignant change. The usual treatment is excision, but often lesional size or location preclude this.Our purpose was to show that cryosurgery is an effective alternative treatment modality for lentigo maligna.Thirty white patients were treated with ...

Otolaryngology–Head and Neck Surgery, 1978
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 ...

Johnson square procedure for lentigo maligna and lentigo maligna melanoma
Clinical and Experimental Dermatology, 2014Lentigo maligna (LM) and lentigo maligna melanoma (LMM) can be difficult to manage surgically. Predetermined margins can be inadequate because of subclinical spread, or can affect function when margins are adjacent to the eye or mouth.To describe our 5-year experience in Nottingham of using the staged square procedure (Johnson square) in excising ...
