[A 38-year-old patient with gastroenteritis and unusual liver lesions]. / 38-jährige Patientin mit Gastroenteritis und ungewöhnlichen Leberherden.

A 38-year-old female presented with symptoms of gastroenteritis including fatigue and epigastric pain. An abdominal ultrasound indicated on the basis of raised liver values showed multiple liver lesions. However, additional imaging using contrast-enhanced ultrasound (CEUS), computer tomography (CT) as well as a magnetic resonance tomography (MR) failed to clarify the diagnosis. A fine needle biopsy revealed the histological diagnosis of peliosis hepatis. After discontinuing oral contraceptive medication, follow-up showed a steady state with clinical well being for at least 24 months.Peliosis hepatis is a rare hepatic disorder involving "bloody cysts" in the liver. Aetiology and pathogenesis remain unclear, but medication or toxins as possible triggering factors are discussed. Different clinical courses have been reported, including total asymptomatic state, unspecific fatigue, epigastric pain, as well as fulminant cases with liver rupture and bleeding complications.

Bacillary angiomatosis and bacillary peliosis in patients infected with human immunodeficiency virus: clinical characteristics in a case-control study.

Clinical characteristics associated with bacillary angiomatosis and bacillary peliosis (BAP) in patients with human immunodeficiency virus (HIV) infection were evaluated in a case-control study; 42 case-patients and 84 controls were matched by clinical care institution. Case-patients presented with fever (temperature, > 37.8 degrees C; 93%), a median CD4 lymphocyte count of 21/mm3, cutaneous or subcutaneous vascular lesions (55%), lymphadenopathy (21%), and/or abdominal symptoms (24%). Many case-patients experienced long delays between medical evaluation and diagnosis of BAP (median, 4 weeks; range, 1 day to 24 months). Case-patients were more likely than controls to have fever, lymphadenopathy, hepatomegaly, splenomegaly, a low CD4 lymphocyte count, anemia, or an elevated serum level of alkaline phosphatase (AP) (P < .001). In multivariate analysis, a CD4 lymphocyte count of < 200/mm3 (matched odds ratio [OR], 9.9; P < .09), anemia reflected by a hematocrit value of < 0.36 (OR, 19.7; P < .04), and an elevated AP level of > or = 2.6 mukat/L (OR, 23.9; P < .05) remained associated with disease after therapy with zidovudine was controlled for. BAP should be considered an AIDS-defining opportunistic infection and should be included in the differential diagnosis for febrile, HIV-infected patients with cutaneous or osteolytic lesions, lymphadenopathy, abdominal symptoms, anemia, or an elevated serum level of AP.
