Abstract

We describe a unique case of atypical natural killer (NK)-cell proliferation likely related to gluten sensitivity, mimicking NK-cell lymphoma. The patient, a 32-year-old man, has had persistent multiple erythematous bull-eye lesions in the stomach, small bowel, and large bowel for 3 years. Histologically, the lesions were well circumscribed and relatively superficial, composed of atypical medium-sized to large-sized lymphocytes with slightly irregular nuclear contours, a dispersed chromatin pattern, and clear cytoplasm. Immunohistochemistry and flow cytometry showed that the cells were NK cells expressing CD56 (aberrantly bright), T-cell intracellular antigen (TIA)-1, cytoplasmic CD3, and CD94, but not surface CD3, with bright aberrant expression of CD7 and a lack of other NK cell-associated markers. Polymerase chain reaction for rearrangement of the T-cell receptor-gamma chain gene showed no evidence of a clonal T-cell population, and in situ hybridization for Epstein-Barr virus encoded RNA was negative. There was no evidence of the involvement of peripheral blood or bone marrow. Although a diagnosis of extranodal NK/T-cell lymphoma was considered because of the atypical morphology and immunophenotypic aberrancy, no chemothera...Continue Reading
