Abraham Buschke specialized in research of venereal disease. In 1926 with Martin Gumpert (1897–1955) he published a treatise on syphilis in children titled Geschlechtskrankheiten bei Kindern. His name is associated with several eponymous dermatological disorders, including:
"Buschke's scleredema": Hardening and thickening of the skin, usually on the upper back, neck, shoulders and face. Its etiology is unknown, but it is often associated with diabetes.
"Buschke-Löwenstein tumor": Also known as giant condyloma acuminatum; a variety of venereal wart characterized by its large, cauliflower-like appearance. Named with Dr. Ludwig Loewenstein (1885–1959).
