Melanoma of the lentigo maligna (LM) type is most commonly located on the head and neck region. This subtype of melanoma poses surgical challenges due to its location on anatomically sensitive areas and frequent presence of subclinical extension. To analyze the reconstruction patterns of LM patients undergoing margin-controlled surgery.

Background: Understanding the factors influencing age at melanoma diagnosis by sex and anatomic site is crucial for developing effective prevention and early detection strategies. While previous research has highlighted sex-based differences in melanoma incidence by age and anatomic distribution, the underlying mechanisms remain unclear. We aimed to investigate sex-specific patterns in melanoma age at diagnosis across different anatomic sites and thickness categories, considering the potential influence of disease progression and detection rates.

Background: Factors associated with nonadherence to guideline-recommended complete excision of suspicious cutaneous lesions are unclear.
Objective: The purpose of this study was to analyze patient, melanoma, and clinician factors associated with initial diagnostic biopsy type and determine whether unwarranted variation from guidelines occurred.
Methods: This population-based, cohort study involved the analysis of data from questionnaires completed by clinicians who managed patients with newly diagnosed, histopathologically confirmed primary invasive cutaneous melanomas reported to the New South Wales Cancer Registry between 2006 and 2007.

The systematics of 37 new species of Devonian Harpetidae from the central and eastern Anti-Atlas Mountains, Morocco, are described. The new material comes from the Dra-Tafilalet region and the province of Tata. A cladistic study was undertaken involving 138 taxa with the objective of assigning the new taxa to the appropriate genera, which are, as far as possible, monophyletic.

If left untreated, it may advance to the point of dermal invasion, developing into lentigo maligna melanoma (LMM). While surgeons have achieved robust clinical outcomes for LM treated with Mohs micrographic surgery (MMS), performing this treatment for LMM remains controversial and is not standard amongst all Mohs surgeons.

Lentigo maligna (LM) often poses a diagnostic challenge due to its clinical and dermoscopic mimicry of benign lesions, leading to delayed diagnosis. Focal areas of reticular disruption have been described as one of the earliest dermoscopic signs observed. To describe a novel dermoscopic sign in LM, namely the presence of a parallel pigmented network.

Melanomas on the dorsum of the hand are exceedingly rare, with limited documentation in medical literature. This report presents seven cases of dorsal hand and finger melanomas, encompassing patients from Australia, New Zealand and Turkey, predominantly women with a mean age of 53 years. The majority were invasive, with a mean Breslow thickness of 1.

Melanoma of the lentigo maligna (LM) type and its invasive counterpart, lentigo maligna melanoma (LMM), occur in chronically sun-damaged skin and tend to have subclinical extension that makes presurgical margin mapping challenging. Reflectance confocal microscopy (RCM) is a non-invasive imaging modality that enables in vivo visualization of the skin at the cellular level, allowing for adequate estimation of LM/LMM margins. We aimed to perform a systematic review and meta-analysis evaluating RCM's performance compared with histopathology in margin mapping of LM/LMM.

Lentigo maligna (LM) is a growing problem worldwide and the main type of melanoma in situ in some Caucasian populations. It presents as a spectrum from atypical intraepidermal melanocytic proliferation (AIMP) to invasive lentigo maligna melanoma (LMM). Accurate diagnosis and staging are crucial for determining appropriate management strategies.

Background: Melanoma in young adults significantly impacts the survival of this age group. There are limited studies that analyze melanoma characteristics in young patients. We aimed to describe the epidemiological, clinical, and histological characteristics of melanoma in young adults and their temporal trends over the last decades.

Cutaneous melanoma in situ (MIS), also known as 'stage 0 melanoma', is a collection of malignant melanocytes in the epidermis and epithelial adnexa, without evidence of microinvasion to the papillary dermis. Distinct histologic subtypes include lentigo maligna (LM), superficial spreading (SS) MIS and acral lentiginous (AL) MIS. LM is the most common subtype, usually diagnosed later in life (median age at diagnosis of 66-72 years) and associated with cumulative ultraviolet radiation exposure.
