ABSTRACT

Eponyms are used almost daily in the clinical practice of dermatology. And yet, information about the person behind the eponyms is difficult to find. Indeed, who is? What is this person’s nationality? Is this person alive or dead? How can one find the paper in which this person first described the disease? Eponyms are used to describe not only disease, but also clinical signs, surgical procedures, staining techniques, pharmacological formulations, and even pieces of equipment. In this article we present the symptoms starting with (U) and other. The symptoms and their synonyms, and those who have described this symptom or phenomenon.

Key words:Eponyms, Skin diseases, Sign, Phenomenon

UGLY DUCKLING SIGN

In 1998, Grob and Bonerandi introduced the “ugly duckling” concept to demonstrate that nevi in the same individual tend to resemble one another and that atypical mole often deviates from the individual’s nevus pattern. In other words, nevus that does not resemble other nevi is more likely to be suspicious of melanoma [1,2].

UKRAINIAN BLACK TONGUE SIGN (c. 1771, Moscow)

Bubonic plague. Black tongue in Bubonic plague. A similar sign – Antichrist sign, where black lips are a classic indication of an infection with Yersinia pestis [3–5].

ULNAR LEPROSY SIGN

Thickening of the ulnar nerve at the elbow [6,7]. A sign of tuberculoid leprosy. Also known as Elbow sign.

UMBILICAL SIGN

Umbilical sign is seen in Marfan syndrome. It is the unusual ability to touch the umbilicus with the right hand, crossing the back, and approaching from the left side, indicating increased length of upper extremity [8].

UREMIA TONGUE SIGN

The tongue is dry in cases of uremia [9].

URIOLLA’S SIGN

The presence in the urine of malarial patients of minute black granules of blood pigment [10].
