Indolent T-Cell Lymphoproliferative Disorder of the Uterine Corpus: A Case Report.

Primary lymphoproliferative disorders of the uterus are rare, with the majority being B-cell diseases or aggressive T-cell disease. We present the case of a 31-yr old in whom an Indolent T-cell lymphoproliferative disorder (iTCLPD) was identified in resection chippings for a suspected fibroid, following presentation with menorrhagia. Laboratory investigations revealed an oligoclonal T-cell infiltrate with the immunophenotype of nonactivated cytotoxic T cells, and a proliferative fraction of 10% to 15%. There was no clinical or radiologic evidence of systemic disease, and the patient remained well with no indication of relapse 1 yr from resection and diagnosis. iTCLPD of the uterine corpus has features in common with the recently described iTCLPD of the gastrointestinal tract and primary cutaneous acral CD8 T-cell lymphoma. Recognition of these parallels is important as few other cases of iTCLPD have been described, and it suggests local resection rather than systemic treatment as the best therapeutic strategy.
