Liver transplantation in Langerhans' cell histiocytosis (histiocytosis X).
Two children with biopsy-proven LCH underwent successful hepatic transplantation for end-stage liver disease. These patients were thought not to have active LCH disease at the time of transplantation, although one had developed a new osteolytic lesion a few months before the operation and the other had suspicious osteolytic lesions at the time of transplantation. The histologic examination of the excised liver showed features consistent with primary sclerosing cholangitis. The two patients had an excellent recovery with no evidence of progression of LCH or recurrence of the underlying disease in the hepatic allograft at 1 and 3 years after organ transplantation.

Clinical and pathological features of bacillary peliosis hepatis in association with human immunodeficiency virus infection.
BACKGROUND: Peliosis hepatis is characterized by cystic, blood-filled spaces in the liver and is seen in patients with chronic infections or advanced cancer and as a consequence of therapy with anabolic steroids. Cutaneous bacillary angiomatosis is a bacterial infection that occurs in patients with human immunodeficiency virus (HIV) infection; its histologic appearance is that of a pseudoneoplastic vascular proliferation. METHODS: We studied liver tissue from eight HIV-infected patients with peliosis hepatis, two of whom also had cutaneous bacillary angiomatosis. For comparison we examined tissue from four patients who had peliosis hepatis without HIV infection. Tissues were examined histologically on routine sections and with special stains and electron microscopy. RESULTS: The histologic features seen in peliosis hepatis associated with HIV infection, but not in the four cases unrelated to HIV infection, were myxoid stroma and clumps of a granular purple material that on Warthin-Starry staining and electron microscopy proved to be bacilli. The bacilli, which could not be cultured, were morphologically identical to those found in the skin lesions of cutaneous bacillary angiomatosis. The clinical courses of two of the patients with this "bacillary peliosis hepatis" indicate that it responds to antibiotic treatment. CONCLUSIONS: HIV-associated bacillary peliosis hepatis is an unusual, treatable opportunistic infection, probably caused by the same organism that causes cutaneous bacillary angiomatosis. Our failure to find bacilli in non-HIV-associated cases implies that other pathogenetic mechanisms may also be responsible for peliosis hepatis.
