[AIDS in Naples in 1800. 12 cases of Kaposi sarcoma described by Tommaso de Amicis]

In 1882, Tommaso de Amicis, dermatologist and venereologist at the University of Naples, Italy, published a description of twelve cases of Kaposi's sarcoma. This article is the second report about the above-mentioned disease after the first description of five cases by Moritz Kaposi ten years earlier. The publication by De Amicis was organized as a collection of case reports followed by a section containing general considerations about the etiopathogenesis, pathology, diagnosis and therapy of Kaposi's sarcoma. Ten cases are typical of the so-called 'classic' form of the disease, that has a peculiar indolent chronic course, while two out of the twelve cases strongly resemble the clinical form of Kaposi's sarcoma currently recognized as that associated with the acquired immunodeficiency syndrome (AIDS). The nature of Kaposi's sarcoma is still being debated, but current evidence suggests that it is a viral-associated, if not viral-induced, tumor and its relationship with AIDS is that of an opportunistic disease. Thus, the presence of the clinical form of AIDS-related Kaposi's sarcoma can be used as a marker of the presence of sporadic cases of AIDS much earlier than its pandemic diffusion.
