[Lymphomatoid granulomatosis: pathologoanatomical study of three cases with a review of the literature and differential diagnosis].

Evidence obtained at pathological investigation concerns 3 cases of lymphomatoid granulomatosis. The disease pertains to lymphoproliferative affections and is of rare occurrence. In addition to common involvement of the lungs, liver, kidneys, spleen, adrenals, etc., there was an advanced lymph node and brain lesion with abundant atypical cells in the infiltrate in the first and third case, respectively. The diagnosis rested on autopsy findings in 1 case and was intravital, established upon morphological examination of intraoperative specimens in 2 cases. Samples obtained at bronchoscopy are not fit for verification of the diagnosis in view of profound necrotic and necrobiotic processes in lymphomatoid granulomatosis.
