Two very rare case reports of bladder transitional cell carcinoma associated with HIV infection in patients treated with combined antiretroviral therapy are described, and discussed on the ground of the most relevant and updated literature resources. Only 13 cases of vesical carcinoma have been reported to date in the setting of HIV infection, but only 3 anecdotal single reports (the last in the y 2001) described clinical, therapeutic, and outcome issues of this rare disease association in some detail. In our patients, micro- or macro- haematuria was the clue for in-depth diagnosis and prompt treatment, which was limited to multiple local interventions in 1 case, but finally required a radical cystectomy in the second patient. No relationship was found with the very favourable underlying HIV-related virological and immunological status, and the present 8–12-month follow-up did not show disease relapses.

A unique case of severe, multiple, microbiologically-confirmed pulmonary Mycobacterium avium-intracellulare lesions occurred in a female with decompensated liver cirrhosis, and went to cure after around 2 y despite the impossibility to deliver an effective antimicrobial chemotherapy, owing to the patient's intolerance. From an extensive literature review, we underline a possible mechanism prompting mycobacterial disease during advanced liver disease, while we retrieved only 2 described cases of possible spontaneous resolution of Mycobacterium terrae lung disease, although both were reported in patients without end-organ liver disease, who received a specific combined chemotherapy for an appreciable time period. On the other hand, while decompensated liver cirrhosis is more frequently complicated by a peritoneal localization of bacteria and very infrequently mycobacteria, the reported case represents the first severe pulmonary localization of multiple lesions due to Mycobacterium avium-intracellulare. Moreover, this extraordinary episode resolved spontaneously within the 2-y follow-up, as documented by bronchoalveolar lavage, culture, high-resolution CT scans, and scintigraphic examination.
