[Pseudotumor extramedullary hematopoiesis. Report of 3 cases and review of the literature].

We report 3 cases of extramedullary hematopoiesis with a sacrococcygeal, right obturatory hole and paravertebral dorso lumbar locations respectively in 30, 34 and 58 years old patients (two males and woman). A medullary tuberculosis was discovered in one case, a beta thalassemia in the second, and the third was classified as idiopathic. Radiologic picture often permitted to evoke the diagnosis on the aspect of a well limited multilocular tumor especially when there is a paravertebral location as in our third patient. Fine needle punction cytologic examination can permit the diagnosis and avoid surgery, except if complications occur.

[Value of immunohistochemistry with paraffin in malignant lymphoma of the lymphoid tissue associated to the mucosa (MALT) of the digestive tract. Apropos of 8 cases with complete review of the literature].

The authors report eight cases of MALT malignant lymphomas arising in the stomach in four cases, small intestine in two cases and salivary glands in two cases. The gastric lymphomas presented in the form of persistent epigastric pain sometimes lasting for several years, in patients with a mean age of 50.5 years. Gastroscopy revealed recurrent ulcerations in two cases and ulcerated or ulcero-fungating tumours in two cases. The two patients with alpha heavy chain disease, both 21 years of age, presented with chronic diarrhoea. The endoscopic appearance consisted of a pseudopolypoid tumour in one case and a mosaic appearance in the other case. The two salivary gland lymphomas involved the submandibular gland in two patients aged 30 years and 50 years. They presented in the form of nodules 1 and 2 cm in diameter, first detected by the patients two months and four months previously. Histological examination demonstrated the presence of typical lesions of MALT lymphoma with, in particular, the presence of constant lympho-epithelial lesions, various forms of centrocyte-like proliferation, varying degrees of plasma cell differentiation, reactive or residual lymphoid follicles in five cases, which were detected on biopsies in three cases. Immunohistochemistry confirmed the monoclonal nature of the tumour in seven cases, i.e. 87.5% of cases. The application of DBB42 and DNA7 antibodies onto paraffin sections demonstrated the absence of DNA7 labelling of CCL in line with Isaacson's findings in favour of the hypothesis of a non-centrofollicular origin of maltomas. Finally, we observed a single case of recurrence in a women with incomplete resection of the primary gastric tumour.

[Malt digestive system lymphomas and alpha heavy chain diseases. Histological and immunohistochemical study. Apropos of 3 cases].

Malt lymphomas are lymphomas developed from mucosa associated lymphoid tissue and may involve many sites such as the gastrointestinal tract, salivary glands, thyroid gland lung, breast and female genital tract. Histologically, their diagnosis is based upon the existence of four elements: centrocyte-like cells that are responsible for lymphoepithelial lesions that are sometimes very difficult to demonstrate reactive or residual follicles and plasma cells. We study 2 cases of gastric Malt lymphoma and one of alpha heavy chain disease involving the small intestine and the stomach and we try to define the common features of Malt lymphoma, alpha chain disease and non-secretary IPSID, which all present the clinical tetralogy mentioned above.

[Gastric xanthelasma. Apropos of 2 of our cases].

On the basis of two personal cases and a review of the literature, we have attempted to define endoscopic and histologic features in gastric xanthelasma. The various etiopathogenic hypotheses published in the literature are reviewed and others are suggested. Attention is drawn to the differential diagnosis with mucus-secreting cell carcinoma. Use of stains for mucus in such lesions is recommended to confirm the diagnosis.

[Thoracic computed tomography data and cytology of the bronchoalveolar lavage fluid in an adult case of Niemann-Pick disease. The physiognomy of the disease in Tunisia].

From a personal observation of a case of the chronic type-B form Niemann-Pick's disease in a 23 year old adult, the authors decided to review all the Tunisian published cases. They bring to light, in a review of the literature, the pulmonary disorder that occurs during this disease and discuss the contribution of computed tomography and the value of broncho-alveolar lavage as a method of diagnosis and prognosis in this disorder.

[Mucosal pseudo-lipomatosis of the colon. Apropos of a case with a review of the literature].

Mucosal pseudolipomatosis of the colon is an infrequent condition that occurs mainly in elderly males, usually involves the left colon, and is manifested clinically by passage of blood per rectum. Among the 26 cases reported in the literature, radiological and endoscopic investigations revealed a dolichosigmoid in the two cases where this feature was mentioned. Colonoscopy shows solitary or multiple whitish-yellowish plaques, which are localized or involve several segments. Histologic studies demonstrate microscopic cavities measuring 20 to 240 mu in diameter. Histochemical stains show that these cavities contain no lipids, suggesting that they are filled with gas. The genesis of these lesions may involve injury to the colonic mucosa followed by penetration of gas during endoscopic and biopsic procedures.

[Ewing's sarcoma. Retrospective study of 108 cases with review of the literature].

108 cases of Ewing's Sarcoma are collected at the "Curie Institute" and studied by the authors using the modern Technics of electron microscopy, cytochemistry, immunohistochemistry and cytogenetics. They raise the histogenesis and etiological factors not entirely resolved yet at the light of literature review.

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.

[Primary digestive tract Kaposi sarcoma with idiopathic CD4+ lymphocytopenia, HIV negative, HHV8 positive].

A 52-year-old Tunisian patient had fever, impaired health and several opportunistic infections (Campylobacter jejuni, Mycobacterium hominis, Herpes virus, Giardia intestinalis, Vibrio metschnikovii). Lymphocytopenia was noted (348/mm3; CD4+: 2.2%; CD4+/CD8+: 0.1). Polymerase chain rection search for HIV was negative in serum and in tumor tissue. Diagnosis of primary digestive Kaposi sarcoma was established at autopsy due to the deep location of the lesions. There was an ulcerofungating tumor spreading over 1.3 m of the duodenojejunum. This is the fourth reported case of CD4+ lymphocytopenia, a new and very rare immunodeficiency syndrome recently defined by the Centers for Disease Control. We detected human herpes virus 8 by immunohistochemistry of tumor tissue. Human herpes virus 8 is implicated in the pathogenesis of Kaposi sarcoma.
