Dyshidrosis is a type of dermatitis, characterized by itchy vesicles of 1–2 mm in size, on the palms of the hands, sides of fingers, or bottoms of the feet. [8] Outbreaks usually conclude within three to four weeks, but often recur.
A beauty mark or beauty spot is a euphemism for a type of dark facial mark so named because such birthmarks are sometimes considered an attractive feature.

Like liver spots, seborrheic keratoses are seen more often as people age. [4] The tumours (also called lesions) appear in various colours, from light tan to black. They are round or oval, feel flat or slightly elevated, like the scab from a healing wound, and range in size from very small to more than 2.5 centimetres (1 in) across. [5]
Such cells might then aggregate into a spot with an irregular shape. [13] They propose that the protrusion of a flat spot is a result of the death of aged cells in the spot and release of lipofuscin bodies. [13] The aggregating cells would form a capsule, and the dense lipofuscin bodies make the protruding spot soft and dark in color. [13]
The adult males grow up to 13–15 millimetres (0.51–0.59 in) long, while females can reach 15–18 millimetres (0.59–0.71 in) of length. In both sexes, the basic coloration of the body is light green, with many small black spots. The eyes are bright orange.
Adalia bipunctata is a small Coccinellid that can feature any one of a large selection of red and black forms. Some forms are similar to Mulsantina picta, but the two white spots on the head of Adalia (in contrast with a large white region or more than two spots) readily separate it.
In certain conditions (in particular, infective endocarditis), clots can migrate from the affected heart valve and find their way into various parts of the body. If this happens in the finger, it can cause damage to the capillaries resulting in a splinter hemorrhage. [citation needed] There are a number of other causes for splinter hemorrhages.
