Metastatic melanoma with unusual histopathology can be diagnostically challenging. One exceptionally rare cutaneous manifestation of metastases is blue-nevus-like metastatic melanoma (BNLMM). A 74-year-old male presented with a blue-gray lesion on his left helix in the same anatomical region of a previously resected lentigo maligna.

Purpose: Abnormal melanin synthesis causes hyperpigmentation disorders like melasma and lentigines, impacting psychological well-being. RNA interference (RNAi) uses small RNA molecules to inhibit gene expression by targeting specific mRNA, silencing genes involved in undesirable cellular functions. This study assessed INTASYL compounds, self-delivering RNAi molecules, designed to target and reduce tyrosinase gene expression to decrease pigmentation.

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.

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.

A man in his thirties patient visited his previous physician with the chief complaint of a pigmented macule on the sole of his left foot that had steadily grown over the past two years. A dermoscopic examination of the lesion showed a parallel ridge pattern (PRP); therefore, acral-lentiginous melanoma (ALM) was suspected, and the patient was referred to our hospital for a more detailed examination. On closer inspection, PRP had a well-defined and irregular border with no variation in color, which is atypical for ALM which is characterized by asymmetrical structure and variation in colors.
