[Hepatic inflammatory pseudotumor regressing with antibiotic therapy].

INTRODUCTION: Inflammatory hepatic pseudo-tumors are rare, non-neoplastic lesions, and their diagnosis is usually made on hepatectomy samples. OBSERVATION: The general health of a 77 year-old patient was suddenly altered and clinical examination (and scan) revealed a hepatic tumor. Diagnosis of inflammatory hepatic pseudo-tumor was evoked by analysis of a biopsy. In view of the age and the general state of the patient we chose prolonged antibiotic therapy rather than hepatic surgery. Nine months later, the tumor had regressed. COMMENTS: Because they are rare (100 cases described), hepatic pseudo-tumors raise two questions: can diagnosis be made simply by biopsy or should one always analyze the complete sample and, if hepatectomy is contraindicated, is non-surgical treatment effective? The progression of our patient permits us to reply positively to both questions.

[Fatal fulminating hepatitis due to Herpes simplex virus type 2 in a young immunocompetent female].

Fulminant herpes simplex viral hepatitis is uncommon in immunocompetent subjects. A 24-year-old woman presenting hepatomegaly with fever was hospitalized after returning from a trip to southern Africa. The patient was neither pregnant nor immunocompromised. Because of recent tropical travel, differential diagnosis included alphabetic hepatotropic virus infection, yellow fever, African hemorrhagic fever, and arbovirus infection. After ruling out other common viral etiologies, a definitive diagnosis of herpes simplex viral infection was made on the basis of clinical and laboratory findings showing high fever, leukopenia, and thrombopenia; of histological examination of the native liver after transplantation showing non-inflammatory confluent focal hemorrhagic necrosis; and on serologic tests demonstrating seroconversion for herpes simplex virus type 2. Outcome after transplantation was rapidly fatal but the death was not directly related to infection. The most likely etiology of fulminant hepatitis in a young woman returning from travel in a tropical area is hepatitis virus B or hepatitis virus E in cases involving pregnancy. However herpes simplex virus should be included in differential diagnosis even in immunocompetent subjects.

Pancreatic ductal changes in HIV-infected patients.

BACKGROUND: AIDS-related sclerosing cholangitis occurs in patients with advanced immunodeficiency, but ductal pancreatic alterations have not been evaluated in large series. METHODS: Twenty-nine consecutive patients with a mean age of 33 years underwent ERCP for biliary work-up. Complete pancreatography was obtained in 28 patients. Serum levels of amylase were increased in 17 patients prior to ERCP. The mean duration of HIV infection was 6.1 years (range 3 to 10 years). RESULTS: Fifteen patients (53.6%) had pancreatographic changes classified according to the Cambridge classification (stage 1, 4 cases; stage 2, 7 cases; stage 3, 4 cases). Dilatations, irregularities, short stenoses of the main pancreatic duct, and irregularities of side branches were the most frequent abnormalities. Fourteen of these 15 patients (93.3%) had cholangitis and a CD4 cell count of less than 60 per cubic millimeter. Risk factors for pancreatic damage were similar in patients with and without pancreatographic changes. Opportunistic infection occurred in 14 of 15 patients with pancreatographic changes (candida, cytomegalovirus, cryptosporidia, microsporidia, and mycobacteria). CONCLUSION: Abnormal pancreatographies were found in about half of the HIV-infected patients who underwent ERCP. The pancreatographic features were suggestive of chronic pancreatitis and were closely related to the presence of AIDS-related sclerosing cholangitis.

[Lingual thyroid and intra-lingual thyroglossal cyst. Apropos of 2 cases].

Lingual thyroid and intra lingual thyro-glossal cyst are two benign tumours of similar embryological pathogenesis respectively with the arrest in the ectopic position of the thyroid gland during its downward migration and from abnormal persistence of the thyro-glossal tract for the cyst. The occurrence of lingual thyroid is rare 1/100,000 patients and outnumbers the incidence of intra-lingual cyst which represents an estimated 2.1% of the thyro-glossal cysts or fistulas. Both lesions are a rare cause of dysphagia and dyspnoea due to oropharyngeal obstruction, and radionuclide scintigraphy combined with CT and/or MRI will establish the diagnosis. Surgical pharyngotomy with an infra-hyoid approach provides excellent access to the lesions and complete removal of the tumours.

[Osteoma of the mastoid: apropos of 2 cases].

The authors report two cases of mastoid osteoma: it is a rare benign tumor attached to the cortex of the mastoid bone, approximatively fifty cases have been described in the english language literature and eight in the french literature. The clinical and radiological characteristics combined with histopathologic evidence demonstrate the diagnosis of mastoid osteoma, the most common type being the compact osteoma. Differential diagnosis should be considered with others benign bone-forming lesions (osteochondroma, chondroma, osteoblastoma, exostosis, fibrous dysplasia...) and with malignant lesions (osteosarcoma...). Surgical removal proposed for cosmetic deformity is a simple procedure for the vast majority of small osteomas. Early surgical intervention is recommended to avoid the evolution toward giant osteoma with potential risks of surgical complications.

[Acute myocarditis in non-typhoid Salmonella infection].

The authors report a case of myocarditis secondary to a Salmonella Virchow infection in a 20 year old non-immunodeficient man without a previous medical history. The outcome was favourable after treatment with fluoroquinolone. The features of this rare complication of non-typhic salmonella infection are discussed with respect to this and four other recently published cases.
