[Lymph-node inflammatory pseudotumor with granulomatous component. Report of a case and review of the literature].

A case of inflammatory pseudotumor of lymph node in a 65 year-old man is described. The case is striking because of a granulomatous component within the lesion, a finding unpreviously described. This lesion, benign by nature, should not be misinterpreted as a neoplastic process, especially lymphomas or soft tissue tumors; problems related to the differential diagnosis are also discussed.

Iron protein succynilate in the treatment of iron deficiency: potential interaction with H2-receptor antagonists.

A prospective, open, multicenter clinical trial was set up to evaluate the potential interaction of ITF 282 with H2-receptor antagonists in patients affected with iron deficiency. Patients treated with H2 blockers and affected with iron deficiency or iron deficient anemia were given one tablet of ITF 282 (60 mg iron) twice daily for 60 days. A second group of iron deficient patients with no anti H2 concurrent treatment were admitted to the same iron treatment, lasting 60 days. To evaluate the outcome of the iron treatment, a comprehensive assessment of laboratory and clinical determinations was adopted in all the patients: special hematology, symptomatology, safety hematology and hematochemistry, urinalysis. Fifty-three patients with iron deficiency and 47 patients affected with overt iron deficient anemia entered the study. After treatment, a significant trend toward the normalization of the main hematologic parameters in both groups was detected. The general tolerability was apparently more favorable in the patients who had also the antiulcer (1 event of diarrhoea) than in those who had ITF 282 alone (2 heartburn, 3 constipation, 2 abdominal pain). There were no indications of subgroups of patients particularly at risk of adverse events, all of which resulted reversible without the need to reduce the dose of medication or to take other medical action. ITF 282 resulted, also when administered together with H2-receptor antagonists, in the expected therapeutic efficacy, with the expected clinical tolerability and biological safety, without signs of possible interaction, negative or positive.(ABSTRACT TRUNCATED AT 250 WORDS)

Gastrointestinal stromal tumors: a "benign" tumor with hepatic metastasis after 11 years.

Gastrointestinal stromal tumors (GIST) constitue the largest category of primary non-epithelial neoplasms of the stomach and small bowel. They are characterized by a remarkable cellular variability and their malignant potential is sometimes difficult to predict. Very recent studies, using mitotic count and tumor size as the best determinants of biological behavior, divide GISTs into three groups: benign, borderline and malignant tumors. We report on a male patient who underwent a right hepatectomy for a large metastasis 11 years after the surgical treatment of an antral-pyloric gastric neoplasm, histologically defined as leiomyoblastoma and with clinical, morphological and immunohistochemical features of benignity (low mitotic count, tumor size < 5 cm, low cellular proliferation index). Histological and immunohistochemical analysis of the hepatic metastasis showed the cellular proliferation index (Ki-67) to be positive in 25% of neoplastic cells, as opposed to the primary gastric tumor in which Ki-67 was positive in only 5% of neoplastic cells. In conclusion, although modern immunohistochemical techniques are now available to obtain useful prognostic information, the malignant potential of GISTs is sometimes difficult to predict: neoplasms clinically and histologically defined as benign could metastasize a long time after oncologically correct surgical treatment. Therefore, benign GISTs also require consistent, long-term follow-up.

[Gastric lymphoma. Anatomo-clinical and prognostic correlations].

In order to assess the prognostic value of some clinicopathological factors of Gastric Lymphoma the authors reviewed 37 consecutive cases observed between 1973 and 1985 with 48 months follow up at least. Age, sex, gross features, site, histological subtype, depth of gastric wall invasion, regional lymph nodes involvement weren't useful parameters. Notable difference exists in survival according to the treatment carried out (surgery and chemoradiotherapy 100% alive & well, surgery and chemotherapy 29% a&w, surgery 17% a&w). The authors compared inflammatory cell population reactive to neoplasm to survival as possible meaningful parameter.

[Proposal for a semiqualitative evaluation method for AgNORs (rap score)].

Nucleolar Organiser Regions (NORs) can be stained in paraffin embedded specimens by a simple silver technique: the black dots formed, called AgNORs, have usually been counted only by eye with "careful focusing", a time-consuming and subjective method. Therefore we propose a new semiquantitative approach based on three patterns of AgNORs configuration of increasing malignancy as previously described by Crocker et al: 1) AgNORs fully aggregated to form a solitary argyrophil structure (pattern RESTING: -R-); 2) AgNORs lying within nucleolus and nucleoplasm (Pattern ACTIVATED: -A-); 3) Numerous small AgNORs distributed through the nucleoplasm, without nucleolar structures (Pattern PROLIFERATING: -P-). We assigned a numerical value to each pattern: R = 1; A = 2; P = 3. These values are multiplied by the relative rate in 100 cells. Eventually we obtain a score (range 100-300): this method shows significant correlation (r = 0.8363: regression equation) compared to the usual count obtained "by eye", tested on a sample of 150 breast cancer. Further studies are under way to validate this method which may represent a cheap and useful tool in AgNORs evaluation.
