متن کاملPathology of 'non-healing (midline) granuloma'.
In a histological study of biopsy and postmortem material from 30 cases of nasal disease in which a clinical diagnosis of 'midline granuloma' or Wegener's granuloma had been given, we selected 10 cases on the basis of the presence of widespread coagulative necrosis and atypical cells. Evidence is provided that such changes represent a malignant neoplasm of histiocytic lymphoma type. Local invas...

Nasal biopsy findings in malignant histiocytosis presenting clinically as lethal midline granuloma are characterised by necrosis and infiltration of atypical histiocytic cells with a diffuse positive reaction for non-specific esterase. This cellular character was common to midline malignant reticulosis, and midline malignant reticulosis and malignant histiocytosis are thought to be the same dis...

متن کامل[Cases of lethal midline granuloma (polymorphic reticulosis) at our department in a recent 10-year period].
We had 18 patients (15 males and 3 females) with lethal midline granuloma (polymorphic reticulosis) in the period from 1981 to 1990. This number was about 5.6% of the total number of patients with malignant head and neck tumors that we encountered during this period. An average of 9.1 months separated the first appearance of disease and the beginning of treatment. Most of the 18 patients underw...
