[Chemodectoma of the orbit. Apropos of a case and review of the literature].

The clinical, follow up and diagnostic features of a case of chemodectoma (paraganglioma) of the orbit are reviewed. 30 cases are reported in the literature. Chemodectoma may arise in any area of the body where non chromaffin paraganglion structures are situated. These are localized in the orbit of the chimpanzee but not in the orbit of man. Malignant behavior of chemodectoma has been a controversial subject, with most authors considering them to be benign tumors. Some authors have diagnosed locally recurrent and infiltrative tumors as malignant. The authors report one case of chemodectoma of the orbit. A 5 year old child has had right exophthalmos. She was treated by tumorectomy. The follow-up is marked by recurrence of the tumor and infiltration of the right hemi-face.

[Papillary carcinoma developing in thyroglossal duct cyst. Apropos of 2 cases].

The authors report two cases of papillary carcinoma of a thyreoglossal duct cyst. In both cases, the thyroïd gland was normal. Clinical manifestations are not specific and the diagnosis is usually made by histopathologic examination which reveals in the majority of cases a papillary carcinoma. When loco-regional or metastatic extension are absent surgical excision of the cyst is sufficient.

[Abdominal actinomycosis: a rare complication of gastric surgery? Apropos of a case].

One case of abdominal actinomycosis is reported which was detected in a diabetic patient three years after surgery for duodenal peptic ulcer. Gastric actinomycosis is very rare and is usually discovered during surgery for gastric mass. The role of surgery as a predisposing condition to infection is discussed. The diagnosis rely on the characterization of the bacteria in cultures from a discharging wall fistula and on histopathologic examination which reveals the characteristic actinomycotic granules.

Gastric MALT lymphoma. A clinico-pathological study of 65 cases. Relationship to Helicobacter pylori.

We report 65 cases of MALT gastric lymphomas. HP was looked for with Giemsa and Whartin Starry stains. Immunohistochemistry was done with PAP method. Anti-HP treatment was used in 9 cases. 38 were of low grade of malignancy, 23 were high grade, 4 were high grade with a low grade component. The mean age was 51.5 years, the sex ratio 1.5. Epigastric pain was the most frequent feature (87.7% of cases). Endoscopically, low grade lymphomas presented as unique or multiple ulcerations (55.3% of cases) with antral localisation (52.6% of cases). 60% of our patients were stage IE, of which 61% had low grade lymphoma, 18% were at stage II2E, 10% at stage III and 10% at stage IV. From 23 operated patients, 29% had early lymphoma which was low grade malignant in 71.5% of cases, and 71% had lymphomas which were widely spread beyond the submucosa. HP was found in 63% of cases. Histologic regression of two early lymphomas of low grade malignancy was achieved after HP eradication.
