Umbilical cord and visceral hemangiomas diagnosed in the neonatal period: A case report and a review of the literature

Umbilical Cord Diseases Affecting Obstetric and Perinatal Outcomes

BACKGROUND

(1) The aim of this article is to describe the physiopathology underlying umbilical cord diseases and their relationship with obstetric and perinatal outcomes. (2) Methods: Multicenter case series of umbilical cord diseases with illustrations from contributing institutions are presented. (3) Results: Clinical presentations of prenatal ultrasound findings, clinical prenatal features and postnatal outcomes are described. (4) Conclusions: Analysis of our series presents and discusses how umbilical cord diseases are associated with a wide variety of obstetric complications leading to a higher risk of poor perinatal outcomes in pregnancies. Knowing the physiopathology, prenatal clinical presentations and outcomes related to umbilical diseases allow for better prenatal counseling and management to potentially avoid severe obstetric and perinatal complications.

Hemangioma of the umbilical cord: A case report on a rare entity

Several hundred cases of placental hemangiomas have been reported in the literature. However, the umbilical cord is extremely uncommon as a site of occurrence. We present a case of postnatal discovery of giant hemangioma of the umbilical cord (HUM) in a Coronavirus Disease 2019 (COVID 19) positive mother. To our knowledge, this is the first reported case of HUM synchronous to a maternal infection with COVID 19. We aim, through this case and a review of the literature, to study the clinicopathological characteristics of this singular entity. Our patient, a 37‐year‐old woman, presented to the Department Of Obstetrics And Gynecology for respiratory distress and loss of fetal movements. Ultrasound examination concluded to intrauterine fetal desmise. After stabilization of the patient, a cesarean section was performed. A macerated fetus was extracted. Placenta showed a giant mass attached to the cord. It was submitted for pathological examination. Gross examination showed that the umbilical cord was inserted eccentrically with a fusiform dilation. Near its placental end, three cohesive solid angiomatous nodules were noted. Microscopic examination revealed lobules of dilated blood‐filled capillaries set in a myxoid stroma. The diagnosis of HUM have been established. HUM arise from endothelial cells of the umbilical vessels. Their etiology, physio‐pathology and pathways of tumorigenesis are not yet well defined. Further studies are needed to explore the pathways of tumorigenesis and to determin the implication of COVID‐19 in HUM.

Changing Course of an Umbilical Cord Mass - Chasing the Diagnosis of Angiomyxoma

Angiomyxoma of the umbilical cord is a rare benign vascular malformation with potential for fetal morbidity and mortality. Gross and histologic features of this lesion are identical to those described as "hemangioma," however "angiomyxoma" is a preferable term as current practice restricts the term "hemangioma" to infantile capillary proliferations that express glucose transporter 1. Here we describe the case of an umbilical cord angiomyxoma with associated pseudocysts diagnosed after delivery at 33 weeks. It presented as a heterogeneous-appearing mass near the fetal cord insertion and mimicked serious fetal anomalies throughout gestation. We found fetal MRI helpful for monitoring this lesion, narrowing the differential, and informing management. Proximity to the fetal end of the cord and uncertainty about diagnosis also required surgical resection of the mass after delivery with umbilicoplasty.

Cutaneous presentations of omphalomesenteric duct remnant: A systematic review of the literature

BACKGROUND

Disorders of the umbilicus are commonly seen in infancy, including hernias, infections, anomalies, granulomas, and malignancies. Meticulous inspection of the umbilicus at birth might reveal a persisting embryonic remnant, such as an omphalomesenteric duct (OMD), manifested by a variety of cutaneous signs, such as an umbilical mass, granulation tissue, or discharge.

OBJECTIVE

To systematically review the available data regarding the presence and management of OMD remnant with cutaneous involvement to suggest a practical approach for diagnosis and treatment.

METHODS

A systematic review of the literature evaluating OMD anomalies presenting with cutaneous symptoms was performed. In addition, an index case of an 11-month-old patient is presented.

RESULTS

We included 59 publications reporting 536 cases; 97% of the patients whose age was noted were infants (mean age 11 months). In 7.5% of the cases, diagnosis was established only after treatment failure. In 6.4% of patients, nonlethal complications were reported, and in 10.3%, the outcome was death, partly due to delayed diagnosis or mismanagement.

LIMITATIONS

Limited quality of the collected data, reporting bias.

CONCLUSION

OMD is relatively rare; however, the clinician must consider this remnant while examining patients with umbilical abnormalities because mismanagement could cause severe morbidity and mortality.
