Abstract

Blueberry muffin baby, describes a neonate with multiple purpuras, associated with several conditions in which extra blood is created in the skin. In this report, a premature baby is introduced who had skin lesions in the form of blueberry muffin at birth, and the related differential diagnosis and the final etiology of this baby will be reviewed.

Introduction

Blueberry muffin rash is consistent with extramedullary hematopoiesisandrefers to multiple purpuras and red-to-violaceous macules, papules, or nodules present within 2 days of life [1-3]. It is a nonspecific and rare clinical presentation in neonates [4,5]. The term “blueberry muffin baby” was primarily used to describe the cutaneous manifestations of congenital rubella in newborns during the American epidemic in the 1960s [6,7]. The lesions tend to occur on the head, neck, and trunk [8]. The differential diagnosis of blueberry muffin baby includes congenital infections from the TORCH (toxoplasmosis, others (hepatitis B or others), rubella, cytomegalovirus, herpes simplex virus) group, dermal extramedullary hematopoiesis or severe hemolysis, many early-onset malignancies or infiltrative neoplastic lesions of the skin, and cutaneous vascular anomalies [9].

In this casereport, a newborn with congenital Cytomegalovirus (CMV) infection manifested as a blueberry muffin baby at birth is described.

Case Presentation

A preterm male newborn was admitted at birth to NICU (neonatal intensive care unit) forrespiratory distress and presenting disseminated violaceous cutaneous lesions. The baby was born preterm weighing 1300 grams at 35 weeks of gestation by cesarean section with the prenatal diagnosis of intrauterine growth retardation. Maternal serological tests for TORCH performed in the first trimester of pregnancy did not show abnormal results and were negative. The lesions were red to violaceous annular macules in size 2- 5 mm (Figure 1). On initial examination, abdominal distention with hepatosplenomegaly (which was also confirmed by ultrasound) and a heart murmur in cardiac auscultation (which was reported as a patent ductus arteriosus by echocardiography) was revealed. The newborn blood laboratory exams showed thrombocytopenia, elevated transaminases, direct hyperbilirubinemia, and coagulopathy.A cerebral ultrasound examination showed periventricular hyper echogenicity. We were not able to perform a brain CT scan due to the unstable condition of the baby. The placental anatomical exam showed features suggestive of congenital infection. It was not possible to get a skin biopsy due to parental dissatisfaction. With early suspicion of congenital viral infections; mother and newborn TORCH screening were requested to find out the causative virus. The results showed that the immunoglobulin M (IgM) titer for CMV (cytomegalovirus) was very positive in the newborn and the level of immunoglobulin G (IgG) antibody was higher than mother.After that, the Polymerase Chain Reaction (PCR) test results of the neonatal saliva and urine were positive for the CMV,and the inclusion body of the virus was observed in the samples. On the sixth day of life, based on clinical, biochemical, and PCR findings, a diagnosis of a blueberry muffin baby with CMV hepatitis was made and intravenous ganciclovir 100 mg per day was initiated for the baby. Within 4 weeks, the skin lesions were faded and ganciclovir continued for 6 weeks. Results of ophthalmologic exams and fundoscopy were within normal limits. Early hearing screening of the infant showed abnormal left ear otoacoustic emission testing, which was scheduled to be re-examined with more specialized tests. The infant was discharged at the age of 50 days with the recommendation of an outpatient visit for follow-up.
