title: Precursor T-cell acute lymphoblastic leukemia/lymphoma involving the uterine cervix, myometrium, endometrium, and appendix.
abstract: This report presents a case of precursor T-cell acute lymphoblastic leukemia/lymphoma (ALL) involving the uterine cervix, myometrium, endometrium, and appendix. The patient was a 38-year-old woman with a history of ALL who had been in remission for 4 years following chemotherapy. The malignant lymphoid infiltrate was characterized by blasts, showing scant cytoplasm, irregular hyperchromatic nuclei, and occasional prominent nucleoli. They were immunoreactive for CD45RB, CD3, CD43, CD34, and focally for TdT. Curiously, the blasts replaced the endometrial stroma and spared the associated epithelium. The patient was again treated with chemotherapy but her disease did not respond. She succumbed to her disease approximately 10 months after her initial evaluation for symptoms related to ALL relapse. Precursor T-cell ALL most commonly presents as a mediastinal mass in adolescent males. Although any organ may be affected, involvement of the female reproductive organs is rare. This case shows some of the varied manifestations of precursor T-cell ALL and highlights the necessity of considering the female reproductive tract as a possible location of relapsing disease.
