The second case in the medical literature of hypersensitivity vasculitis induced by glybenclamide is reported, and for the first time vasculitic lesions are demonstrated in the histopathological study of liver tissue. The case was a male patient admitted because of a febrile illness and generalized malaise of long duration. He had diabetes mellitus that was being treated with glybenclamide. Physical examination disclosed fever, poor general condition, hepatomegaly, and red nodes in the finger-tips of both hands. Abnormal laboratory parameters included normochromic normocytic anemia, leukocytosis with a high eosinophil count, and markedly elevated erythrocyte sedimentation rate. There was as well slight cytolysis and marked elevation of cholestatic serum enzymes without hyperbilirubinemia. Biopsy of the skin lesions demonstrated anular granulomata, a common lesion in diabetics. The histopathological study of the liver revealed a vasculitic hypersensitivity reaction with conspicuous granulomata located in the vicinity of blood vessels and in the wall of portal arterioles, the endothelium of the latter being disrupted at different levels. Glybenclamide withdrawal resulted in a clinical, biological and histopathological cure of the disease. Unlike the previously reported case, the patient remains alive, and this may partly have been due to early institution of corticosteroid therapy.

Sixty-two cases of disseminated tuberculosis seen over a 6-year period in a large teaching hospital are reviewed. The commonest symptoms were cough, loss of weight and appetite, fever and general malaise. Headache, when present, was highly specific for meningeal involvement. Pyrexia, hepatomegaly, evidence of weight loss and adventitious chest sounds were the commonest physical signs. Hyponatraemia, hypo-albuminaemia and abnormal liver function were common. Severe haematological abnormalities were not present in any of the patients. The best diagnostic sources were sputum, bronchial brushings and biopsies of liver and bone marrow. Forty patients (64%) died, 31 deaths being directly attributable to disseminated tuberculosis. Twenty-five patients had associated diseases. More female patients and Black patients died than did males, Whites or Coloureds (mixed race). The duration of symptoms prior to admission was, in general, long in comparison with the interval between admission and death. We should like to re-emphasize the need to consider disseminated tuberculosis early in the differential diagnosis of a wasting pyrexial illness with chest symptoms and signs, even in the absence of a miliary or miliary-like chest radiograph.

We report a non alcoholic, Chinese, 65 years old male that presented in august, 1992 with painful hepatomegaly of rapid installation and malaise. Ultrasound examination revealed multiple substitution images, diagnosed histologically as hepatoma. Serum alpha fetoprotein was 6600 U/ml. Malaise increased and the patient died two months later. This patient had a porphyria cutanea tarda and a chronic hepatitis diagnosed 6 years before. He also had positive titers for hepatitis C virus antibodies. In patients with porphyria cutanea tarda, hepatoma frequency is 400 fold higher and hepatitis C virus infection is highly prevalent. Thus, the surveillance of these patients with periodic alpha feto protein determinations and abdominal ultrasound examinations is recommended, specially in those infected by hepatitis C virus.

Twenty-two abdominal tuberculosis patients seen at Abbassia Fever Hospital in Cairo, Egypt from January 1990 to August 1992 are described; their mean age was 21.5 years, range 9-54 years; 17 were female. Common symptoms were fever, malaise, abdominal pain (64%) and weight loss (82%). Chest X-rays were normal in 14 patients (64%), but ultrasonography/computerized tomography of the abdomen was abnormal in 20 patients (91%), with adenopathy the usual finding. Anaemia and a raised erythrocyte sedimentation rate were present in all patients, and purified protein derivative skin test (5 Tu) was positive in 82%. Predominant abnormal physical findings were abdominal (86%), including hepatomegaly/splenomegaly and abdominal mass. Diagnosis was made from biopsy material (caseating granulomas) in 6 patients by laparotomy, 1 by laparoscopy, and 3 by cervical or supraclavicular node biopsy; and from laboratory examination of excretions in only 4 patients (acid-fast bacilli in stools of 2, mycobacteria in urine and menstrual fluid). Eight patients required presumptive diagnosis after response to specific isoniazid (+ethambutol) antituberculous therapy.

The signs and symptoms exhibited by 29 patients with an acute illness in whom antibodies to hantavirus were detected are described. In the severe cases the most striking signs and symptoms were the persistence for 2 or 3 weeks of a severe sore throat with pyrexia that developed early in the illness, followed by swelling of the face, neck and extremities, with arthropathy and prolonged malaise that lasted for months. A macular erythematous rash, hepatomegaly with abnormal liver function tests, and a tendency to haemorrhage was a later feature of the severe cases. Mild cases presented with a variety of signs and symptoms that were very difficult to link together as a syndrome.

This review summarizes the clinical and pathological findings of 52 cases of hepatic angiomyolipoma to discern and establish the most pertinent clinical and pathologic characteristics of the tumor. The disease was symptomatic in 60% of the patients. Abdominal pain or distress was the most common symptom, appearing in 37% of the patients, followed by malaise and upper abdominal mass or hepatomegaly. Of the 52 patients, only three (5.8%) showed associated tuberous sclerosis. Antemortem diagnosis of the tumor has been made with increasing frequency with the recent advent of computed tomography (CT) and ultrasound (US). The tumor was usually visualized as a hyperechoic mass by US imaging and as a low density mass less than -20 Housefield units by CT, and was hypervascular on angiography. The tumor was usually yellow to light tan, depending on the amount of fat tissue. Histologically, the tumor was characterized by an admixture of mature fat cells, blood vessels, and smooth muscle cells, with occasional foci of extramedullary hematopoiesis. The amount of smooth muscle component varied and often exhibited hypercellularity, pleomorphism with occasional bizarre giant cells, and moderate motitic activity. These features are considered conducive to an erroneous diagnosis of malignant tumor. However, since no malignant counterpart has been reported, it can easily be accurately differentiated histologically, if one is aware of the entity and can identify the three components of the tumor; blood vessels, smooth muscle cells, and fat. With regard to the histogenesis of angiomyolipoma, primitive mesenchymal cells around blood vessels may be the precursor cells.

Three cases of post-sinusoidal hepatic blood flow obstruction as the main feature of antiphospholipid syndrome are reported. Clinically, these patients developed jaundice, malaise, ascites and hepatomegaly. Ultrasonography-Doppler and hepatic venography showed small hepatic vein disease in two and partial occlusion in the suprahepatic segment of inferior vena cava in the remaining patient. In all, anticardiolipin antibodies were positive and activated partial thromboplastin time was prolonged. This experience emphasizes that in patients with post sinusoidal portal hypertension, a systematic search for antiphospholipid syndrome must be carried out.

Progressive disseminated histoplasmosis (PDH), a recognized defining illness of AIDS, is an opportunistic fungal infection caused by Histoplasma capsulatum. The authors report a case of PDH in a HIV-infected African child from a Histoplasma capsulatum non-endemic area. An 8-year-old girl from Kwazulu/Natal, South Africa, was admitted to King Edward VIII hospital with pyrexia and respiratory distress. Pale with generalized lymphadenopathy, she had been sick with general malaise and fever for 3 weeks. A punched-out painless ulcer was present on the child's lower left leg and she had ulcerative lesions on the tip of her tongue and the angle of her mouth. There was a tender hepatomegaly and clinical signs of pneumonia, while a chest roentgenogram showed right upper lobe consolidation with early cavitation. The purified protein derivative tuberculin skin test was negative and no acid-fast bacilli were detected on three sputum samples taken on different days. A Western blot test conducted for antibodies to HIV was positive. Additional laboratory tests were conducted. The patient was treated with parenteral acyclovir for herpesvirus infection, ceftriaxone for severe community-acquired pneumonia, and trimethoprim-sulfamethoxazole because Pneumocystis carinii infection was part of the clinical differential diagnosis. Bone marrow aspirate and trephine biopsy revealed yeast forms of H. capsulatum. The girl died on the second day of hospital admission, before antifungal therapy could be commenced.

A total of 51 cases (19 males and 32 females) of intrahepatic cholangiocellular carcinoma (CCC) from a low-endemicity area of primary liver cancer was analyzed during the periods from 1958 to 1979 and from 1984 to 1991. The mean annual age-adjusted incidence rate was 0.44 for males and 0.56 for females per 100,000 inhabitants. CCC was diagnosed before death in only 31%. There was a female predominance in patients over 70 years of age (p < 0.05). At presentation, malaise (85%), weight loss (73%) abdominal pain (50%) and hepatomegaly (80%) were common. The median survival time from diagnosis was 2 months. The mean age at the time of death was 72 years (range 41-92). At autopsy, cholelithiasis was found in 61% (81% in patients older than 70 years) and cirrhosis in 30% of patients. Cholelithiasis was more common in CCC (p < 0.01) than in hepatocellular carcinoma cases with the same mean age. Not one case of inflammatory bowel disease was found. The gross appearance of the tumor was predominantly massive (49%) or multinodular (35%). The most common histological features were tubular pattern of growth (82%) and abundant fibrous stroma. Metastases were particularly associated with the lymph nodes (41%), skeleton (26%) and lungs (16%).

We performed a 17-year retrospective analysis of 10 cases of hepatocellular carcinoma presenting as pyogenic liver abscess. Spontaneous tumor necrosis and biliary obstruction caused by tumor thrombi, superimposed with bacterial infection, were the two major pathogeneses. Exact diagnosis of the underlying hepatocellular carcinoma was made for five of the 10 patients before management was attempted. Main clinical manifestations included fever, chills, right-upper-quadrant pain, malaise, anorexia, jaundice, and hepatomegaly. Characteristics such as middle age and male sex, seropositivity for hepatitis B and/or hepatitis C, chronic liver disease, unexplained anemia, marked weight loss, and a severely inversed albumin/globulin ratio raise suspicions about the underlying hepatocellular carcinoma. Management strategies included percutaneous drainage (n = 3), surgical drainage (n = 4), and hepatectomy (n = 3) in addition to administration of parenteral antibiotics in all cases. The prognosis was dismal, with a mean survival of 3.5 months (range, 8 days to 6 months).
