The term "bubonulus" (small bubo) is used to designate a bubolike swelling that may occur in chancroid at sites other than the groin, particularly on the penis. The swelling is smaller than a regular bubo and, moreover, is not a bubo at all. There is no invasion of the lymph glands, but there is a circumscribed infiltration around lymph vessels.
Infiltrations in the lymph vessels imitating the typical lymphadenitis more or less closely can be encountered in such diseases as tuberculosis1 and tularemia. In lymphogranuloma venereum such an occurrence does not seem to have attracted attention, although the importance of the involvement of the lymph vessels is well recognized for this disease.
I saw 3 patients in whom a bubonulus developed after infection with lymphogranuloma venereum.
