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 (T) and other. The symptoms and their synonyms, and those who have described this symptom or phenomenon.

Key words: Eponyms, Skin diseases, Sign, Phenomenon



Hyperostosis occuring in the midline of the hard palate (Fig. 1), called torus palatinus or hyperostosis located on the lingual aspect of the mandible, termed torus mandibularis [1].

Figure 1: Tori sign.



Tattoos on women that are not religious or ceremonially required for their culture. Often on the lower back area; they were originally used to signify a life of prostitution. This practice continues today but sometimes these tattoos are now seen in the non-prostitute population, as sign of admiration for the romanticized prostitution lifestyle which is linked to drug abuse, physical violence, and sexually transmitted diseases. The origin of the term dates from the 17th century Yakuza practice of tattooing prostitutes on the back. Prostitutes in the Edo period, called ‘Yujo’ tattooed themselves with the name of their regular customer as a sign of their loyalty. This tattoo is referred to as ‘Irezumiko’, which starts with the customer’s name and ends with the kanji character (inochi), which means life, so this tattoo means “I give my life to ‘name’.”


Linear aggregation of neoplastic lymphocytes along the dermal-epidermal junction seen in histopathology of mycosis fungoides (Fig. 2) [2].

Figure 2: Toy Soldier sign.



Linear gingival erythema, an erythematous band an the free gingiva that follows the contour with a reddish chevron appearance (Fig. 3). An indication of HIV disease [36]. Painful, acute necrotizing ulcerative gingivitis. Also called HiVR and NUP signs, ulceromembranous gingivitis, Vincent’s infection, Vincent’s War sign, and ANUG sign.

Figure 3: Trench Mouth sign.



French physician, 1862-1950. His name is associated with Vincent’s Disease or Vincent s Angina. It is also widely known as Trench Mouth, due to an outbreak in soldiers in trenches during World War One. Borrelia vincentii used to be spread out worldwide, but is now mainly in countries that are not very developed [3,4].


An epidemic disease of Japan due to a zoonotic proteus implanted by the bite of a mite (kedani). It is marked by fever, swelling of the lymph-glands, and an exanthematous eruption fever [7]. Synonym: akamushi disease, flood fever, inundation fever, island disease, island fever, Japanese river fever, kedani fever, mite typhus, scrub typhus (Fig. 4), shimamushi disease, tropic typhus, tsutsugamushi.

Figure 4: Tsutsugamushi sign.



An ulcer that is characterized by undermined edges and is usually painful (Figs. 5A and B) [8,9].

Figure 5: (a and b) Tuberculous Ulcer sign.



A skin boil that has the resemblance of a small eye (Fig. 6). It can have a 10mm white area with a black center. The black center is the abdomen’s caudal tip of the parasitic chigoe flea that has burrowed into the skin to lay eggs [10,11].

Figure 6: (a-d) Tunga Eye sign.



Discoloration (bruising) of the skin of the loin in acute hemorrhagic pancreatitis; adverse prognostic (Fig. 7). Also known as Grey Turners sign [12].

Figure 7: Turner’s sign.



English surgeon, 1877-1951 (Fig. 8). Served with the Royal Army Medical Corps in the First World War. First described in 1920 Grey Turner’s sign, in the British Journal of Surgery, it was described as a sign of hemorrhagic pancreatitis. As a young surgeon, he travelled around the world, being received by the Pope, Benito Mussolini, the King of Italy and King Alfonso of Spain. Five years before his death, Grey Turner was made President of the International Society of Surgeons. After the war, Grey Turner was briefly famous for performing one of the earliest operations to attempt the removal of a bullet from a soldier’s heart. The bullet was never removed, but Grey Turner’s surgery saved the patient’s life. Worked with early cancer research, and anticipated the development of chemotherapy [12].

The ‘twin-spotting’ phenomenon due to loss of heterozygosity and somatic recombination during late embryogenesis. The earlier the mutation during embryogenesis, the wider is the involvement of the skin, central nervous system and other structures, and, in contrast, later postzygotic mutations generate only skin involvement. Twin spotting phenomenon of Happle and Steijen has been proposed to explain this phenomenon (Phakomatosis pigmentovascularis) [1315]. In this hypothesis, somatic mutations on nearby genes leads to mosaic spots in close proximity to one another. Phakomatosis pigmentovascularis has been classified into four types namely; type I: Nevus flammeus and epidermal nevus, type II: Nevus flammeus, Mongolian spots, ± nevus anemicus, type III: Nevus flammeus, nevus spilus, ± nevus anemicus, and type IV: Nevus flammeus, Mongolian spots, nevus spilus, ± nevus anemicus.


This is sign in gonerrhea. It should be remembered that purulent leakage from the coil is not enough to definitively diagnose the disease, because it can also be caused by many other causes. Confirmation of anterior urethral involvement may be so-called try two glasses. It consists in the fact that if the urine is put into two glasses, it will be cloudy in the first glass and in the second glass it will be transparent. The cloudy urine in both glasses indicates that the rear coil is also occupied.


The phenomenon of transmissible bacterial lysis; bacteriophagia. When to a broth culture of typhoid or dysentery bacilli there is added a drop of filtered broth emulsion of the stool from a convalescent typhoid or dysentery patient, complete lysis of the bacterial culture will occur in a few hours. If a drop of this lysed culture is added to another culture of the bacilli, lysis will take place exactly as in the first. A drop of this culture will then dissolve a third culture, and so on through hundreds of transfers, d’I Ierelle attributes this phenomenon to the action of an ultramicroscopic parasite of bacteria which he named the bacteriophage [16].


British bacteriologist, 1877-1950 (Fig. 9). Fellow of the Royal Society was an English bacteriologist and was the original discoverer in 1915 of bacteriophages (viruses that infect bacteria). He studied medicine at St Thomas’s Hospital, London, was superintendent of the Brown Institute for Animals (a pathology research centre), and he was also professor of bacteriology at the University of London. He researched into Johne’s disease, a chronic intestinal infection of cattle, and also discovered that vitamin K is needed by growing leprosy bacteria [17].

Figure 9: Frederick William Twort (by National Portrait Gallery).



French-Canadian microbiologist, 1873-1949 (Fig. 10). Generally known as the discoverer of the bacteriophage, a virus that infects bacteria. He experimented with the possibility of phage therapy. D’Herelle has also been credited for his contributions to the larger concept of applied microbiology. After studying medicine in Paris and Leiden, Hérelle went to Guatemala City to direct the bacteriology laboratory of the municipal hospital and teach microbiology at the local medical school. In 1909 he was sent by the Mexican government to study microbiology at the Pasteur Institute in Paris. While there, he experimented with a bacterium known to cause enteritis (digestive tract inflammation) in certain insects. In the course of his work Hérelle occasionally noticed clear spots (areas free of bacteria) on gelatin cultures of the bacterium under study. Subsequently he investigated a form of dysentery afflicting a French cavalry squadron during World War I, and he happened to mix a filtrate of the clear areas with a culture of dysentery bacteria. The bacteria were quickly and totally destroyed by an unknown agent in the filtrate that Hérelle termed an “invisible microbe”; he later renamed it a bacteriophage [18].
