[Tumor seeding of the abdominal wall after fine needle cytologic puncture of the liver. Apropos of a case].

Tumor seeding of the abdominal wall during fine needle puncture-aspiration of the liver is a very rare complication. The authors report a case of this complication affecting a 50-year-old Senegalese woman. She underwent echo-guided fine needle cyto-puncture of a hepatocellular carcinoma arising from the left lobe, followed by left lobectomy. The subcutaneous nodule was discovered 42 months after cyto-puncture. Histology following its excision revealed infiltration of carcinomatous hepatocytes between the fibers of rectus abdominis. There was no recurrence and the patient was well 10 months after excision of the subcutaneous nodule. With a review of 10 others cases reported in the literature, the authors feel that, although rare, this complication must be avoided and suggest a system for the protection of structures through which the needle passes.

[Amoebic liver abscess: echographic aspects].

Amoebic liver abscess is the most frequent location of the extra-intestine amibiasis with an epidemio-endemic repartition in our areas. We are reporting in this study the main echographic patterns that can be found. 117 documents were collected and studied between 1982 and 1988 in the main hospitals of Dakar (SENEGAL). Most of the patients were young, the range of age being between 25 and 55 years old and 83% of them, were male. The diagnosis of the amoebic liver abscess was evocated on the basis of the following clinical and biological symptoms: 54.38% of painful haetomegaly, 42.10% of pleuro-pulmonary and digestive signs, 3.50% of long lasting isolated fever, non specific biological sign of inflammation, 74.57% of positive hemaglutination test. An echographic test was performed before the anti-parasitic treatment with an echotomograph PHILIPS SDR 1500 in real time using a probe of 3 MHZ. The amoebic abscess of liver was detected by the echography in all cases. The unique abscess (83.10%) was the most frequent form. It was localized in the right liver (64%) and had an heterogeneous echostructure (55.70%). The hypo-echogeneous form (36.50%) was the earlier stage of the collecting abscess. The liquid form (07.80%) was observed in the latter stages of the disease. Some difficulties to determine the amoebic abscess may appear when primitive liver cancer or pyogensus abscess are present. In these cases it is necessary to analyse the liquid of ponction to be affirmative.

[Congenital cystic dilatation of the choledochus: apropos of a case diagnosed in an adult Senegalese women].

The authors report a case of congenital cystic dilatation of the choledochus diagnosed on a 37 years old senegalese woman. It is an uncommon affection in Africa. The clinical presentation with various signs is reviewed. Ultrasound or cholangiography confirms the diagnosis. Surgical excision of the cystic dilatation is the best treatment because of the high risk of cancerisation.

[Polycystic kidney. Clinical and familial aspects. Apropos of 29 cases].

The polycystic kidney disease is a hereditary malformation seldom described in Africa. Nineteen cases among 6 men and 13 women were seen in the internal Medicine Service in seven years. The range of age was 28 to 77 years. Ten other patients (of whom four were less than 15 years old were discovered via systematic family investigations and confirmed by ultra sound. The diagnosis was based essentially on consistent clinical signs and the presence of at least 5 cysts in each kidney. Infectious manifestations were the most frequent, presented in 37% of the cases. These acute infections can affect either the urinary ducts or a hepatic or renal cyst. The family investigations established that a third of the subjects examined were asymptomatic or had lumbar pain and hematuria never associated with their underlying cause.

[Apropos of hepatorenal polycystic disease associated with cirrhosis].

The authors report a case of association of cirrhosis with (autosomal dominant) polycystic kidney and liver disease, which is hereditary malformation. The occurrence of hepatic cysts during the disease is relatively common, and the development in general is benign. In this case, the large hepatic cysts are responsible of biliary ducts compression, with clinical and biological cholestasis. Portal hypertension like impaired hepatocellular function develop because of cirrhosis.

[Contribution of echography in the diagnosis ruptured liver abscess (Apropos of 4 cases)].

The authors report 4 cases of ruptured hepatic abscesses in peritoneum (2 cas) and in pleural (2 cases). The cases occurred in 3 men (two of them were alcoholic) and one woman who was in the postpartum period. The cases confirm the classic pictures according to which, ruptures of hepatic abscesses have unclear clinical presentation whether they are amoebic or bacterial in origin! In these cases, ultrasound is very useful in the rapid detection of peritoneal or pleural abscesses which can be confirmed by ultrasonically guided fine needle punction When the channel from the intra hepatic abscess can be visualised, or when they are a coexisting hepatic and peritoneal pleural abscesses, the diagnosis is clear. However when the abscess has been completely emptied of its contents the diagnosis may the difficult.

[Low prevalence of ant-hepatitis c virus antibodies in hepatocellular carcinoma in Senegal].

Senegal is a country with a high incidence of hepatocellular carcinoma (HCC). The role of the hepatitis B virus (HBV) in the genesis of HCC is well established. To evaluate the role of the hepatitis C virus (HCV) in the occurrence of HCC in Senegal, second-generation serologic tests were used to compare the prevalence of anti-HCV antibody in subjects with HCC and in controls without liver disease. A polymerase chain reaction assay was used to look for HCV RNA in sera from patients with HCC and anti-HCV antibody. HBV markers were assayed in all study subjects. Prevalences of anti-HCV antibody were 10.9% (7/64) in the HCC group and 5% (3/58) in the control group (NS). In the HCC group, anti-HCV antibody was found in 2.4% (1/42) of subjects positive for the hepatitis B antigen (HBsAg) versus 27.2% (6/22) of subjects negative for the HBsAg (p < 0.01). HCV RNA was detected in five of six anti-HCV-positive HCC patients. Prevalence of the HBsAg was 65.6% (42/64) in the HCC group versus 17.2% (10/58) in the control group (p < 10-8). Anti-HBV antibody was detected in 48.3% (28/58) of controls versus 6.3% (4/64) of HCC patients (p < 10-8). These data do not support a close epidemiologic association between the HCV and HCC in Senegal, where the HBV remains the main viral cause of HCC.
