A FEMALE INFANT weighed 870 g at birth and had Apgar scores of 7 and
8 at 1 and 5 minutes, respectively. She was born at 26 weeks' gestation to a mother with advanced malignant pleural mesothelioma.1 A histologic evaluation of the products of conception
revealed no evidence of malignancy. Immediately following delivery, the infant
developed moderate stridor, grunting, and nasal flaring. She was intubated,
received exogenous pulmonary surfactant, and was transferred to the neonatal
intensive care unit.
Ventilator assistance was discontinued on day 7 and she was subsequently
weaned from continuous positive airway pressure by day 23. Her hospital course
remained uneventful until day 54 when edema, discoloration, and proptosis
of the right eye were noted. Funduscopy demonstrated immature retinal vasculature
and no papilledema or proliferative retinopathy. Computed tomography of the
head revealed a soft tissue mass in the intracoronal aspect of the right orbit
with ascension of the mass posteriorly into the right cavernous sinus (Figure 1). Ultrasonography confirmed a homogeneous
2.1-cm solid mass in the right retro-orbital region. Doppler interrogation
demonstrated prominent flow within the mass (Figure 2).

Denouement and Discussion: Orbital Capillary Hemangioma
Figure 1. Computed tomographic
scan of the head at age 54 days. A 2.1-cm soft tissue mass involves the intracoronal
right orbit. The mass extends posteriorly into the right cavernous sinus.
Figure 2. Ultrasound with Doppler
interrogation. A 2-cm retro-orbital mass is noted. Doppler flow interrogation
demonstrates the highly vascular nature of the lesions.
Capillary hemangiomas are the most common benign orbital tumor of infancy.2, 3, 4 They are seen
nearly twice as frequently in girls as in boys and occur more frequently in
premature neonates.2, 3, 4, 5, 6
Capillary hemangiomas primarily involve the head and neck region, with approximately
90% demonstrating a visible cutaneous component (strawberry nevus).2, 3 Deep orbital lesions comprise
only 3% of all capillary hemangioma.2, 3
They are typically situated in the upper lid or superior aspect of the orbit
and often lack a cutaneous component. The most common presentation for orbital
hemangioma is the development of proptosis and/or amblyopia.2, 3
Capillary hemangiomas are benign tumors composed of capillary endothelial
cells. Fewer than 25% of lesions are present at birth, but rapid development
is common in the first months of life.3
Rapid proliferation of these lesions can produce ulceration, bleeding, infection,
necrosis, and compression of adjacent structures.7
Large lesions may result in thrombocytopenia secondary to intralesional platelet
sequestration (Kasabach-Merrit syndrome).7, 8
Most capillary hemangiomas resolve spontaneously. Typically, 50% of capillary
hemangioma resolve spontaneously by age 5 years, 70% by age 7 years, 90% by
age 9 years, and the rest by adolescence.2, 3
The clinical course of capillary hemangioma is similar for lesions from various
sites. Since spontaneous regression is the rule, treatment is only indicated
if visual disturbance is present.4, 7
Corticosteroids are the primary pharmacologic treatment used to control hemangiomas.4, 9 Interferon is effective in refractory
cases.4 Use of intralesional cryotherapy
and sclerosing agents are of limited value. Radiation treatment is only considered
for life-threatening lesions. Because orbital capillary hemangiomas are highly
vascular lesions with the blood supply directly from the internal or external
carotid artery, surgical intervention poses considerable risk for massive
blood loss and is rarely indicated.
Other diagnostic considerations include an array of ocular and/or orbital
tumors, including retinoblastoma, intraocular malignancy, solid rhabdomyosarcoma
dermoid cyst, teratoma, lymphangioma, glioma, neurofibroma, and meningioma.7 Another consideration is the possibility of transplacental
metastasis of maternal malignancy. Metastasis of malignancy to products of
conception is rare. Fewer than 100 cases of malignant metastasis to products
of conception have been reported, to our knowledge; malignant melanoma is
the most common of these, accounting for nearly 30%. Leukemia, lymphoma, and
breast adenocarcinoma combined account for an additional 30%.10
Metastasis to the fetus occurs in only 27% of these cases in which products
of conception are involved. Eighty percent of the cases are associated with
malignant melanoma or hematopoietic malignancies.10
No cases of mesothelioma metastatic to products of conception have been reported
to our knowledge.
In light of the clinical presentation, the well-circumscribed nature
of the lesion, and the prominent vascular supply, a diagnosis of orbital capillary
hemangioma was made. Because of progressive ocular manifestations, prednisone
was administered, and follow-up imaging studies demonstrated no further progression
of size. The infant did well and was discharged on the 70th day of life.
