ABSTRACT
UNLABELLED: Phototherapy for hyperbilirubinemia has rare complications. We report a case of phototherapy induced eruption in a neonate with transient porphyrinemia. Our patient received phototherapy due to hyperbilirubinemia secondary to erythroblastosis fetalis (hemolytic disease of the newborn). He developed a cutaneous rash in the light-exposed areas of his skin. Erythrocyte and plasma porphyrins were elevated at the time. Phototherapy induced eruption with a transient porphyrinemia is rare. Upon review of the literature, we found only 5 other cases of patients with phototherapy induced rash and elevated porphyrins reported. We compared the five other reported cases to our case, looking at drug exposure, age, and receipt of exchange transfusion. CONCLUSION: While this is an uncommon occurrence, transient porphyrinemia should be considered in neonates with phototherapy induced cutaneous eruption and erythroblastosis fetalis.

Juvenile xanthogranulomatosis (JXG) represents a subset of non-Langerhan cell histiocytosis that typically manifests in younger children with skin lesions. Unresectable central nervous system (CNS) disease is difficult to treat. We describe the case of a 13-year-old successfully treated with adjuvant radiation therapy for symptomatic intracranial and leptomeningeal JXG. An extensive literature review was performed to identify all previous CNS JXG cases utilizing radiation, of which six of eight total patients demonstrated temporary or long-term improvement of neurologic disease. This suggests that radiation should be considered in cases unresponsive to conventional treatment options.
