Abstract:
Purpose:To explore the clinical and pathological characters and immunophenotype of 2 cases nasal type extranodal NK/T cell lymphoma primarily derived from adrenal gland.Methods:The clinical and pathological features of the 2 cases were analyzed and the immunostaining for UCHL-1,CD43,CD3,CD56,TIA-1 and LMP1 was performed using EnVision TM . IgH and TCR? gene rearrangement was analyzed by using PCR techniques.Results:Both patients were male and aged 50 and 51. Occupying masses in their right adrenal glands was detected. The two tumors showed similar morphological features, composing of small to middle sized and multi formed cells and growing invasive. Inflammatory background,necrosis and vessel involvement were seen. Positive surface staining of UCHL-1,CD43,CD56 and cytoplasma staining of CD3 was demonstrated. TIA-1 and LMP1 expression was also detected. No clonal rearrangement in both IgH and TCR? genes was detected.Conclusions:Nasal type extranodal NK/T cell lymphoma can occur primarily in adrenal gland. It should be distinguished from other small cell malignant tumor of this site.
