What does this research mean for the field?

Severe warm autoimmune hemolytic anemia in infants can be a presenting sign of a sacrococcygeal teratoma, and complete surgical excision of the tumor can result in sustained hematologic remission. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To describe an uncommon presentation of warm autoimmune hemolytic anemia secondary to a mature Altman type II sacrococcygeal teratoma in a one-month-old infant.

Overview

Case report reveals severe warm autoimmune hemolytic anemia associated with sacrococcygeal teratoma in an infant, indicating tumor excision achieves hematologic remission.

Key Points

To describe an uncommon presentation of warm autoimmune hemolytic anemia secondary to a mature Altman type II sacrococcygeal teratoma in a one-month-old infant.
Evaluated a 1-month-old female infant presenting with jaundice, dark urine, severe anemia, hepatosplenomegaly, and a positive direct antiglobulin test for IgG using pelvic magnetic resonance imaging.
Administered supportive therapy including packed red blood cell transfusions, intravenous methylprednisolone, oral prednisone, and folic acid.
Performed complete surgical resection with coccygectomy followed by histopathological examination and monitored clinical and hematologic outcomes over 2 years.
Pelvic MRI confirmed a solid-cystic lesion with intrapelvic extension consistent with an Altman type II sacrococcygeal teratoma, and pathology confirmed a mature teratoma without malignancy.
Hemoglobin normalized by postoperative day 15, and the direct Coombs test converted to negative following complete tumor resection.
At 2 years of follow-up, the infant demonstrated normal psychomotor development, intact walking and posture, and complete fecal continence without tumor recurrence.
