Spitzoid melanocytic lesions characterized by spindle and/or epithelioid tumour cells can occur anywhere on the skin but the acral presentation of Spitz naevus is very rare and comprises about <4% of all Spitz naevi. However, data regarding their dermatoscopic features on the acral volar skin are scarce. Herein, 11 cases of acral Spitz naevus involving the glabrous skin with predominant dermatoscopic findings of atypical fibrillar pattern in non-pressure bearing areas, a structureless pigmentation involving both the furrows and the ridges are presented.

Actinic keratoses (AK) usually occur on sun-exposed areas in elderly patients with Fitzpatrick I-II skin types. Dermatoscopy and ultrasonography are two non-invasive tools helpful in examining clinically suspicious lesions. This study presents the usefulness of image-processing algorithms in AK staging based on dermatoscopic and ultrasonographic images.

Background: Basal cell carcinoma (BCC) is a prevalent type of skin cancer in which the inherent subjectivity of dermoscopy poses diagnostic challenges. Existing AI systems, which provide mainly image-level insights, lack the interpretability that is crucial for effective clinical decisions and patient education.
Patients And Methods: Our study developed a refined BCC dataset from the Human‒Machine Adversarial Model (HAM10000), which was annotated by clinicians to identify key diagnostic features.

Skin cancer is one of the most common, deadly, and widespread cancers worldwide. Early detection of skin cancer can lead to reduced death rates. A dermatologist or primary care physician can use a dermatoscope to inspect a patient to diagnose skin disorders visually.

Background: Physiologic volar melanotic macules (P-VMM) are understudied. Trauma has been suggested as a predisposing factor. Little has been published over the last several decades.
