The incidence of lentigo maligna (LM), in situ (LM) or invasive (lentigo maligna melanoma, LMM), has increased during the last decades. Due to functional or cosmetic outcomes, optimal treatment with surgical excision may not be appropriate in some cases. We tried less invasive therapy, immunocryosurgery, as a single treatment for LM or combined with surgery for LMM, with better aesthetic results. Three patients with LM or LMM not amenable to complete surgical excision were selected. LMM patients underwent limited surgical resection of the invasive area...

BACKGROUND: Lentigo maligna (LM), a form of melanoma in situ, is treated to prevent progression to lentigo maligna melanoma (LMM). Surgical treatment is the gold standard. However, treatment guidelines are based on expert opinion and comparative studies are lacking. OBJECTIVE: The objective of this study is to assess the diagnostic methods and clinical management of LM patients among European dermatologists and residents. METHODS: A survey consisting of 29 questions about diagnostic methods and treatment options used for LM patients was sent to 3308 members of the European association of Dermatologists and Venereologists (EADV)...

BACKGROUND: Though the combination/collision of nevi or lentigo simplex and hemangiomas is frequent, the malignant collision tumor melanoma-hemangioma is exceptional and can sometime clinically simulate a benign collision. To date, a series of collision tumors of hemangiomas associated with either benign or malignant melanocytic skin lesions (MSL) has yet to be studied by non-invasive imaging and clinico-pathologic correlates. METHODS: We present 10 cases of patients with collision tumors of hemangioma with different MSL including: 2 in situ lentigo-maligna melanoma, 1 invasive melanoma, 5 melanocytic nevi, and 2 lentigo simplex...

BACKGROUND: Several dermoscopic and in vivo reflectance confocal microscopy (RCM) diagnostic criteria of lentigo maligna (LM)/lentigo maligna melanoma (LMM) have been identified. However, no study compared the diagnostic accuracy of these techniques. OBJECTIVE: We evaluated the diagnostic accuracy of dermoscopy and RCM for LM/LMM using a holistic assessment of the images. METHODS: 223 facial lesions were evaluated by 21 experts. Diagnostic accuracy of the clinical, dermoscopic and RCM examination were compared...

Pigmented facial macules are common on sun damage skin. The diagnosis of early stage lentigo maligna (LM) and lentigo maligna melanoma (LMM) is challenging. Reflectance confocal microscopy (RCM) has been proven to increase diagnostic accuracy of facial lesions. A total 154 pigmented facial macules, retrospectively collected, were evaluate for the presence of already described RCM features and new parameters depicting aspects of the follicle . Melanocytic nests, roundish pagetoid cells, follicular infiltration, bulgings from the follicles and many bright dendrites, and infiltration of the hair follicle (i...

Mechanisms involved in melanoma invasiveness and metastasis are essential to understanding the behavior of this aggressive melanocytic skin cancer. The epithelial-mesenchymal transition (EMT) is considered fundamental for overcoming the in situ stage of melanoma and its proliferation beyond the basal membrane. Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) are key molecules involved in EMT about whose expression in lentigo maligna (LM) and lentigo maligna melanoma (LMM) little has been studied so far...

OBJECTIVE: Malignant melanoma accounts for nearly 75% of all skin cancer deaths, and the incidence is on the rise in the United States. External ear melanoma (EEM) is rare, and there is little long-term data regarding the clinical behavior of this melanoma site. This study analyzes the demographic, clinicopathologic, and survival characteristics of EEM. METHODS: The SEER database was queried for EEM cases from 1973 to 2012 (8,982 cases). Data analyzed included patient demographics, incidence trends, and survival outcomes...

A strategy combining covalent conjugation of photosensitizers to a peptide ligand directed to the melanocortin 1 (MC1) receptor with the application of sequential LED light dosage at near-IR wavelengths was developed to achieve specific cytotoxicity to melanocytes and melanoma (MEL) with minimal collateral damage to surrounding cells such as keratinocytes (KER). The specific killing of melanotic cells by targeted photodynamic therapy (PDT) described in this study holds promise as a potentially effective adjuvant therapeutic method to control benign skin hyperpigmentation or superficial melanotic malignancy such as Lentigo Maligna Melanoma (LMM)...

Prognosis has been shown to be worse for patients with multiple primary melanomas than those with a single melanoma. One recent retrospective study showed that older, white men were at higher risk of multiple primary melanomas. In our institution 2057 melanomas were diagnosed between January 1994 and March 2016. We identified 99 (4.8%) patients who had multiple primary melanomas. The average number of melanomas was 2.5 (range: 2-10). The site for first and second melanomas was similar in 30%. We found that subsequent melanomas were more likely to be in situ and thinner in terms of Breslow thickness and Clarks level...

Importance: The management of lentigo maligna (LM) and LM melanoma (LMM) is challenging because of extensive subclinical spread and its occurrence on cosmetically sensitive areas. Reflectance confocal microscopy (RCM) improves diagnostic accuracy for LM and LMM and can be used to delineate their margins. Objectives: To evaluate whether handheld RCM with radial video mosaicing (HRCM-RV) offers accurate presurgical assessment of LM and LMM margins. Design, Setting, and Participants: This prospective study included consecutive patients with biopsy-proven LM and LMM located on the head and neck area who sought consultation for surgical management from March 1, 2016, through March 31, 2017, at the Dermatology Service of the Memorial Sloan Kettering Cancer Center...

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 describe a rare case of synchronic conjunctival melanoma and lentigo maligna on the face.

PD-L1 expression in the tumor immune microenvironment is recognized as both a prognostic and predictive biomarker in patients with cutaneous melanoma, a finding closely related to its adaptive (IFN-γ-mediated) mechanism of expression. Approximately 35% of cutaneous melanomas express PD-L1, however, the expression patterns, levels, and prevalence in rarer melanoma subtypes are not well described. We performed immunohistochemistry for PD-L1 and CD8 on 200 formalin-fixed paraffin-embedded specimens from patients with acral (n=16), mucosal (n=36), uveal (n=103), and chronic sun-damaged (CSD) (n=45) melanomas (24 lentigo maligna, 13 'mixed' desmoplastic, and 8 'pure' desmoplastic melanomas)...

Amelanotic lentigo maligna melanoma represents <2% of melanomas. Diagnosis is delayed owing to the lack of lesion pigmentation and advanced disease at presentation. Excision with appropriate margins is the treatment standard, but the starting point for such margins is often unclear. We describe 2 patients with amelanotic melanoma treated by Mohs micrographic surgery (MMS) that would not have been cleared by wide local excision alone and provide an extensive review of the literature. Both patients presented with histologic diagnoses of malignant melanoma, one with a barely perceptible biopsy site scar on the left infraorbital cheek/lower eyelid (Breslow 1...

Diagnosis and management of lentigo maligna (LM) and LM melanoma (LMM) is challenging. Novel noninvasive imaging technologies such as reflectance confocal microscopy (RCM) have advanced the ability to better diagnose and monitor challenging lesions. In addition, the new handheld RCM (HRCM) together with the use of videomosaics has allowed an accurate evaluation of large lesions in concave/convex areas of the body (eg, the face). Herein, we review the impact of HRCM in the detection, treatment decision-making, and monitoring of 5 cases of complex facial LM/LMM...

<p>The Food and Drug Administration approved Ruxolitinib in 2011 for the treatment of primary myelofibrosis. Five-year safety data showed a higher incidence of skin cancer in patients treated with Ruxolitinib compared to best available therapy for myelofibrosis. This report presents a series of five patients with history of myelofibrosis treated with Ruxolitinib who subsequently developed numerous skin cancers with aggressive biological behavior. Each patient in this report was treated by a Mohs surgeon affiliated with an academic institution...
