T-Acute Lymphoblastic Leukemia Presenting as Bilateral Ovarian Mass in a Toddler.

T-acute lymphoblastic leukemia (T-ALL) generally have nodal presentation while B-cell leukemia and lymphoma may have extra-nodal or visceral involvement. Intra-abdominal presentation of T-ALL is exceedingly rare. Bilateral ovarian involvement at the time of initial presentation of T-ALL has never been described in children, though it may be seen during relapses. The authors describe a toddler with T-ALL who presented with bilateral ovarian mass. Despite complete resolution of ovarian mass post-induction chemotherapy, minimum residual disease in bone marrow was high reaffirming aggressive nature of disease.
