He wrote about it in many articles and succeeded in its treatment with diathermic. He first described "the nail sign" appearing by the removal of the crust of an oriental sore. A part of his published work was concerned with parasitosis. In 1923, he described the etiologic agents of "gale cereal" in Turkey. Behçet dealt with superficial and deep mycosis and their treatments. Due to his observations, he described the dermatitis of fig in 1933. In 1935, at the Dermatology Congress in Budapest, he was honoured for his studies on mycosis. He was also in the publishing vanguard to improve Turkish medicine and he was responsible for the first dermato-venerology journal of Turkey called ’’Turkish Archives of Dermatology and Syphilology’’ in 1924. In 1939, he was elected as a correspondent member to the German scientific journals ’’Dermatologische Wochenschrift’’ and ’’Medizinische Wochenschrift’’. The same year, he has been promoted to ordinary professor. The most important work that Behçet brought to Turkish medicine was the monograph published in 1940 called ’’Clinical and Practical Syphilis, Diagnosis and Related Dermatoses’’. Every page of this book contains an aspect of syphilis and the footnotes, provides a wealth of detailed information about the differential diagnosis of other skin diseases. As a result, scientists had the chance to learn about syphilis and dermatology at the same time.

Behçet continued as the Head of the Department of Dermatology and Venereal Diseases until 1947.

According to his symptoms, the illness had been diagnosed. From the aetiology, syphilis and tuberculosis were suspected. Austrian doctors had called an unknown protozoal disease. Ophthalmologists had described the ocular symptoms as iritis, which might be the result of syphilis, tuberculosis or streptococcal or staphylococcal infections. After several iridectomies, the patient had completely lost his vision. Behçet continued to follow up the patient for many years. In 1930, a woman suffering from irritation in her eye and with lesions in her mouth and genital regions was referred to Behçet's clinic and told him that these symptoms had been recurring for several years. He consulted the patient until 1932 and tried
