Key Words. Kaposi’s sarcoma • Penis • AIDS, urological manifestations Abstract. Kaposi’s sarcoma of the penis is an initial manifestation of AIDS and the practising urologist should be aware of this form of presentation. We report 2 young intravenous drug abusers with this tumor in the male geni­ tourinary system. The clinical course is unfavorable; therefore prompt diagnosis and management, based on the early recognition of the lesion, must be achieved.

AIDS was first described as ‘the syndrome of Kaposi’s sarcoma and opportunistic infections’ [1,2], and epidemiologically related to homosexual men [3], Since then, Kaposi’s sarcoma, a slowly progressing malignant mes­ enchymal proliferation of atypical spindle cells and vas­ cular channels, clinically presenting as red-purple plaques and nodules, has become one of the characteris­ tic morphologic features of HIV infection [4]. We report 2 cases of Kaposi’s sarcoma of the penis, constituting both an initial manifestation and a distinct urological lesion of AIDS.

Case Reports Case 1 A 28-year-old male intravenous drug abuser presented with a rapidly growing red-purple nodule on his glans penis. Biopsy con­ firmed the clinical suspicion of Kaposi’s sarcoma (fig. 1). HI V infec­ tion was therefore investigated and diagnosed. Three months later the patient developed a miliary form of tuberculosis which is now being treated.

Case 2 A 26-year-old male, addicted to parenteral drugs for more than 10 years, was admitted to the emergency room suffering from an overdose. He presented multiple cutaneous lesions in the penis, scrotum, right calf and leg that were suspected to be Kaposi’s sarco­ mas. His relatives reported a history of disorientation, slowly pro­ gressing dementia and fever. HIV infection was diagnosed. Blood cultures were positive for Salmonella enteriditis and Candida albi­ cans was isolated from the sputum. He died during a sudden hypo­ tensive episode a few weeks after diagnosis. Autopsy revealed a single pulmonary and multiple splenic ab­ scesses. Pneumocystis carinii pneumonia was also present, together with a candidiasic meningitis, central nervous system demyelinating changes and intense gliosis. The adrenal glands showed a gross and microscopic picture of hemorrhagic necrosis with cytomegalovirus (CMV) inclusions. Histology confirmed that the cutaneous plaques were Kaposi’s sarcoma.

Discussion Apart from being the most constant dermatologic finding in AIDS [5], Kaposi’s sarcoma is still a remark­ able head and neck manifestation: oral, pharyngeal or in the cervical nodes. This last form has been clinically mis­ taken for persistent generalized lymphadenopathy [6, 7],

Even before the AIDS epidemic, the finding of CMVDNA in the genome of Kaposi’s sarcoma cells, together with certain seroepidemiologic studies, linked CMV to the causation of this tumor [15]. Nowadays, both CMV infection and Kaposi’s sarcoma arising in the context of AIDS are common findings and the coincidence of both entities in case 2 is in no way striking. The increased frequency of the HLA-DR5 antigen reported in Kaposi’s sarcoma [3] raises the possibility that the severely immunocompromised individuals that develop this tumor, in this case HIV-infected drug ad­ dicts, are genetically susceptible to ‘opportunistic’ Kapo­ si’s sarcoma. Finally, we want to emphasize the possibility that Kaposi’s sarcoma of the penis, same as primary testicu­ lar lymphoma [16, 17], presents as the initial manifesta­ tion of underlying and previously undiagnosed AIDS. Urologists should always be aware of this form of muco­ cutaneous presentation in order to establish a prompt diagnosis and management of the patient.

Similarly, an unreported equivalent misdiagnosis could occur for the inguinal region. Despite a great individual variability, the median sur­ vival of patients with Kaposi’s sarcoma seems to be sig­ nificantly shortened [8]. In fact, the unfavorable clinical course of our 2 patients agrees with this poor progno­ sis. Kaposi’s sarcoma in the genitourinary system has been described in the adrenal glands, epididymis, pros­ tate, seminal vesicles, bladder and penis [9-12] and therefore can be considered a distinct urological mani­ festation of AIDS. In the series that Kaplan et al. [13] presented, no Kaposi’s sarcoma was reported in 60 patients suffering from AIDS. Recently, Miles et al. [14] stated that only a small number of these patients shows significant urolog­ ical manifestations and presented 3 cases of cutaneous genitourinary Kaposi’s sarcoma of 120 patients with AIDS or AIDS-related complex. In our 2 cases, genitou­ rinary Kaposi’s sarcoma of the penis and scrotum is the initial manifestation, and in case 1 the only consulting sign of previously undiagnosed AIDS.
