Background: Reprogramming of energy metabolism to enhanced aerobic glycolysis has been defined as a hallmark of cancer.

Objective: To investigate the role of the mitochondrial proteins, β-subunit of the H -ATP synthase (β-F1-ATPase), and heat-shock protein 60 (HSP60), and the glycolytic markers, glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and pyruvate kinase M2 (PKM2), as well as the bioenergetic cellular (BEC) index, in melanoma progression.

Material And Methods: The expression of energy metabolism proteins were assessed on a set of different melanoma cells representing the natural biological history of the disease: primary cultures of melanocytes, radial (WM35) and vertical (WM278) growth phases, and poorly (C81-61-PA) and highly (C8161-HA) aggressive melanoma cells.

Early diagnosis improves melanoma survival, yet the histopathological diagnosis of cutaneous primary melanoma can be challenging even for expert dermatopathologists. Analysis of epigenetic alterations, such as DNA methylation, that occur in melanoma can aid in its early diagnosis. Using a genome-wide methylation screen, we assessed CpG methylation in a diverse set of 89 primary invasive melanomas, 73 nevi, and 41 melanocytic proliferations of uncertain malignant potential, classified based on interobserver review by dermatopathologists.

Dermatology Division, Department of Medical, Surgical and NeuroSciences, University of Siena, Siena, Italy.

Background: Differential diagnosis of clinically atypical nevi (aN) and early melanomas (eMM) still represents a challenge even for experienced dermoscopists, as dermoscopy alone is not sufficient to adequately differentiate these equivocal melanocytic skin lesions (MSLs).

Objectives: The objectives of this study were to investigate what were the most relevant parameters for noninvasive differential diagnosis between eMM and aN among clinical, personal, and dermoscopic data and to evaluate their impact as risk factors for malignancy.

Methods: This was a retrospective study performed on 450 MSLs excised from 2014 to 2016 with a suspicion of malignancy. Read More

Importance: Two pathways have been hypothesized for the development of cutaneous melanoma: one typically affects the head and neck, a site with chronic sun damage, and the other affects the trunk, which is less exposed to the sun. However, the possible cause of limb melanomas is less studied under this hypothesis.

Objective: To investigate the association between phenotypic characteristics, pattern of UV radiation exposure, and risk of melanoma on different body sites. Read More

Pigmented epithelioid melanocytoma (PEM) is considered an intermediate grade melanocytic lesion that is histologically indistinguishable from epithelioid blue nevi associated with Carney complex. PEM are characterized by an intradermal population of heavily pigmented epithelioid-shaped melanocytes along with some spindled and dendritic melanocytes with frequent melanophages. These melanocytic tumors occasionally involve regional lymph nodes but only rarely result in distant metastases. Read More

Neurocristic cutaneous hamartomas (NCHs) are rarely reported tumors with divergent differentiation derived from persistently active pluripotent cells from the neural crest. They result from aberrant development of the neuromesenchyme, and they can express fibrogenic, melanocytic, and/or neurosustentacular differentiation. Thus, congenital melanocytic nevus also represents a neurocristic dysplasia of the skin in which cells are melanogenic cells arrested in development located in the reticular dermis, and nodular proliferative neurocristic hamartoma may arise within a congenital melanocytic nevus.

BACKGROUND Carney complex (CNC) is a genetic disorder that presents as an adrenocorticotropic hormone (ACTH)-independent variant of endogenous Cushing syndrome. It was first reported in 1985 and was described as a form of multiple endocrine hyperplasia associated with mutations of the c-AMP-dependent protein kinase (PRKAR1A) gene that causes bilateral adrenal hyperplasia. We report a case of an incidentally found CNC in a 35-year-old male, and this case report focuses on the diagnostic scheme as well as the surgical treatment of this rare challenging condition.
