BACKGROUND: Lentigo maligna (LM) is an in situ variant of melanoma. Our objective was to systematically review clinical and histological clearance and recurrence rates of imiquimod treatment of LM with emphasis on progression to lentigo maligna melanoma (LMM). METHODS: PubMed, EMBASE and the Cochrane library were searched from inception to May 2015. Articles were included if they described histologically proven LM treated with imiquimod 5% monotherapy or combined with another topical therapy...

Follicular malignant melanoma (FMM) is an exceedingly rare variant of melanoma. Only 8 cases have been reported in the literature thus far. Often bland on physical examination, FMM shows a striking histologic pattern, with atypical melanocytes sometimes consuming the entire follicle and extending into the dermis. Criteria have been suggested to help distinguish FMM from lentigo maligna melanoma; however, no clear criteria distinguish this cancer clinically. FMM cannot be distinguished from follicular metastases of melanoma based on histology, requiring close clinical correlation and detailed history taking on the part of the practitioner...

The aims of this study were to determine the clinical and histological characteristics of melanoma in transplant recipients, the mutation profile (BRAF, NRAS and c-KIT genes), and the immune tolerance of the tumour microenvironment by immunohistochemical study of the expression of IDO, PD1, PD-L1, CD8 and FoxP3. The study population comprised patients who had undergone a renal transplant in Nantes University Hospital who developed post-transplantation melanoma. Twenty cases of melanoma out of 4,663 transplant recipients were studied...

AIM: To evaluate clinical, pathologic and genetic features of desmoplastic melanoma (DM). MATERIALS & METHODS: Analysis of all DM records from 1991 to 2015. RESULTS: The most common location of DMs was the head and neck (69%); median age and follow-up were 60.5 and 7.3 years, respectively. A familial predisposition for DMs and others malignancies was analyzed. Thin Breslow thickness (<4.5 mm) was associated with an intraepidermal component or a previous lentigo maligna, whereas high Breslow thickness (>4...

BACKGROUND: Topical imiquimod is sometimes used for lentigo maligna (LM) in-situ melanoma instead of surgery, but frequency of cure is uncertain. Pathological complete regression (pCR) is a logical surrogate marker for cure after imiquimod, although residual LM and atypical melanocytic hyperplasia may not be reliably distinguished. A trial comparing imiquimod versus surgery might be justified by a high imiquimod pCR rate. OBJECTIVES: Primary: to estimate pCR rate for LM following imiquimod...

Melanin, primarily responsible in humans for hair, eye and skin pigmentation, is produced by melanocytes through a process called melanogenesis. However, the abnormal accumulation of melanin causes dermatological problems such as café-au-lait macules ephelides (freckles), solar lentigo (age spots) and melasma, as well as cancer and vitiligo. Hence the regulation of melanogenesis is very important for treating hyperpigmentary disorders. Numerous antimelanogenic agents that target tyrosinase activity and/or stability, melanosome maturation, transfer and trafficking, or melanogenesis-related signaling pathways have been developed...

Confocal microscopy is a modern imaging device that has been extensively applied in skin oncology. More specifically, for tumor margin assessment, it has been used in two modalities: reflectance mode (in vivo on skin patient) and fluorescence mode (on freshly excised specimen). Although in vivo reflectance confocal microscopy is an add-on tool for lentigo maligna mapping, fluorescence confocal microscopy is far superior for basal cell carcinoma and squamous cell carcinoma margin assessment in the Mohs setting...

Distinguishing lentigo maligna (LM) and lentigo maligna melanoma (LMM) from background pigmented non-melanoma lesions is challenging. The field of solar damage can obscure clinical assessment, and diagnostic ambiguities are created due to the overlap of the clinical features of LM with other benign lesions. Moreover, margin assessment on histology is limited by the resemblance between melanocytic hyperplasia of actinically damaged skin and scattered atypical melanocytes of LM/LMM. Dermoscopy has made a significant contribution but is often not sufficient for diagnosis and margin assessment...

Melanomas are a wide range of tumors that differ in their epidemiology, morphology, genetic profile, and biological behavior. They can be grouped as superficial spreading melanoma, lentigo maligna, and nodular melanoma. Reflectance confocal microscopy is useful for the evaluation of skin lesions that are dermoscopically doubtful by increasing diagnostic accuracy and specificity. This article provides a comprehensive overview of the different confocal main morphologies of distinct melanoma types as a function of the anatomic location of the tumor...

Malignant melanoma is a rare disease in Asians but potentially the most aggressive form of skin cancer worldwide. It can occur in any melanocyte-containing anatomic site. Four main cutaneous melanoma subtypes are recognized: lentigo maligna melanoma, superficial spreading melanoma, acral lentiginous melanoma (ALM), and nodular melanoma. Generally, excessive exposure to ultraviolet (UV) radiation increases the risk of melanoma. The exception is ALM, which is the most common melanoma subtype in Asians and is not associated with UV radiation...

AIM OF THE STUDY: Melanoma subtypes have different aetiological characteristics. Child height is positively associated with adult melanoma; however, a clarification of associations with specific melanoma variants is necessary for an improved understanding of risk factors underlying the histologic entities. This study investigated associations between childhood height and future development of cutaneous melanoma variants. METHOD: A cohort study of 316,193 individuals from the Copenhagen School Health Records Register, with measured heights at ages 7-13 years who were born from 1930 to 1989...

Light therapy has been incorporated into the art of healing and cosmesis for thousands of years and currently has found utility in many areas of medicine. Various modalities of cosmetic phototherapy are detailed, as well as the indications and mechanism of action for each modality. These modalities can be used to treat many common cosmetic conditions, including acne vulgaris, solar lentigo, and melasma. Phototherapy is considered a safe and effective option in the treatment of many of these disorders.

Age spots, also called solar lentigines and lentigo senilis, are light brown to black pigmented lesions of various sizes that typically develop in chronically sun-exposed skin. It is well known that age spots are strongly related to chronic sun exposure and are associated with photodamage and an increased risk for skin cancer, however, the mechanism(s) underlying their development remain poorly understood. We used immunohistochemical analysis and microarray analysis to investigate the processes involved in their formation, focusing on specific markers associated with the functions and proliferation of melanocytes and keratinocytes...

Lentigo maligna is the most common type of facial melanoma. Diagnosis is complicated, however, as it shares clinical and dermoscopic characteristics with other cutaneous lesions of the face. Reflectance confocal microscopy is an imaging technique that permits the visualization of characteristic features of lentigo maligna. These include a disrupted honeycomb pattern and pagetoid cells with a tendency to show folliculotropism. These cells typically have a dendritic morphology, although they may also appear as round cells measuring over 20μm with atypical nuclei...
