3. pleural effusions, involvement of the bilateral lower
extremities, and soft tissue masses in the retroperito-
neum. Her previously diagnosed diabetes insipidus,
hydronephrosis, and renal insufficiency were attributa-
ble to ECD. Despite recommendations of treatment
with interferon-alpha with possible radiotherapy for
local palliation, the patient declined further medical
treatment.
The patient was followed in our ophthalmology
clinic for further comfort care of orbital disease and
microbial keratitis. By 2 months’ follow-up, her vision
had progressed to no light perception in each eye. She
died from complications of the disease 3 months after
her initial presentation.
Methods
We wished to explore specifically the ophthalmic exam-
ination details and disease progression of cases of
Erdheim-Chester disease with orbital involvement and
therefore chose to limit our case review to only include
cases published in the ophthalmology literature.
Published cases were identified by a PubMed search
for the terms “Erdheim-Chester disease” with the
terms “orbit” and “orbital.” Cases published in
English, reported in the ophthalmic literature, and
that discussed patients with pathology-proven ECD
involving the orbits were included. Cases that lacked
ophthalmic examination data were excluded.
Results
Our PubMed search identified 13 separate publications
reporting ECD with orbital involvement in the English
language ophthalmic literature.1−13
One additional pub-
lication was identified by review of all cited references.14
These 14 total publications reported 21 separate patients
with ECD involving their orbits. Of these patients, 19/21
reported ophthalmic examination details, treatment, and
disease course and were therefore included for review
and analysis (Table 1).
Age at time of presentation ranged from 26 to 77
years with a mean age of 50 years. Of these patients, 14/
19 (74%) were men and 5/19 (26%) were women.
Average reported follow-up was 119 months. These
demographics were similar to previously published lar-
ger series in the non-ophthalmic literature.15,19
In this
review, 17/19 cases exhibited the classic presenting
symptoms of proptosis and motility disturbance with
diffuse, intraconal orbital involvement. Notable differ-
ences included one patient presenting with motility
restriction and optic disc edema and another patient
with bilateral lacrimal gland enlargement.8,9
Additionally, two patients had mass extension past the

invade the cavernous sinus.1,2
Vision loss in cases of
orbital ECD was most commonly secondary to orbital
or anterior visual pathway compression of the optic
nerves, however involvement of the central nervous
system with masses in the posterior visual pathway
have resulted in homonymous hemianopia.9,20
The degree of vision loss in each described patient
varied, with severe visual impairment and vision pro-
gression to no light perception only occurring in 6/19
(32%) of our reviewed cases.1,8−12
The average time
from initial ophthalmic consultation to NLP vision in
the 5/6 of these cases reporting this information was 3
years, with a range in timing from 4 months to 10

The average follow-up time for patients that
preserved vision was 41 months. Our patient pro-
gressed to profound vision loss in both eyes despite
treatment with systemic corticosteroids, orbital radio-
therapy, and bilateral orbital decompression. There is
no standard treatment for ECD with orbital involve-
ment. Typically, treatment options involve a combina-
tion of surgical debulking, radiation, and medical
therapies including systemic corticosteroids, che-
motherapeutic agents, or immunotherapy.3,12,16
Discussion
Erdheim–Chester disease is a rare, xanthogranuloma-
tous disease characterized by diffuse infiltration of the
long bones, heart, lungs, kidneys, and retroperitoneum
by histiocytes and lipid-laden macrophages.
Histopathology classically reveals fibrosing xanthogra-
nulomas with foamy histiocytes and Touton giant cells.
Periorbital findings include xanthelasma of the eyelids
and eyelid thinning.1
ECD with orbital involvement is
less common, occurring in about 25% of these
patients,15,16
and with less than 40 total cases reported
in the English-language literature.12
In contrast to other
xanthogranulomatous diseases that may involve only
the anterior orbit, ECD orbital lesions are diffuse and
more likely to cause vision loss.12
Classic presenting
symptoms with orbital involvement include painless,
progressive, bilateral proptosis that may be associated
with decreased visual acuity. Additional ophthalmic
manifestations most often include ophthalmoplegia,
optic disc edema or atrophy, and retinal striae.1
Imaging studies most commonly reveal bilateral, enhan-
cing intraconal masses, however there may be extraconal
lesions present as well.1,2,4,8,11,17
Histopathology of orbital
lesions show diffuse xanthogranulomatous findings includ-
ing histiocytes, Touton giant cells, and fibrous tissue with
clustered plasma cells, lymphocytes, and eosinophils.
Histiocytes exhibit positive expression of CD68 and are
negative for CD1a and S-100, differentiating this disease
from Langerhans cell histiocytosis.[4]
These lesions are
infiltrative, found to completely replace the orbital fat,
and may extend into the extraocular muscles and optic
nerve.18
ECD has a very poor overall prognosis with one
case series reporting the death of 22 of 37 patients (59%)
within an average follow-up period of 32 months.16
Although there is no standard treatment for ECD with
orbital involvement, most therapeutic approaches involve a
combination of systemic corticosteroids, chemotherapeutic
agents, or immunotherapy.3,12,16
The successful use of
interferon-alpha has been reported, with one case series
of 3 patients demonstrating marked improvement of orbi-
tal and systemic disease, excellent toleration of therapy, and
duration of improvement over 3 years of maintenance
dosing.21
Another case report described a patient with
complete, dramatic resolution of proptosis and improve-
ment in visual acuity after administration of cladribine, a
purine analogue targeting monocytes, after failure of
response to several other chemotherapeutic medications.14
Although other reported patients failed to show such
impressive results with cladribine administration,9,10,14
this patient had no recurrence of orbital signs and symp-
toms at 2 years after cessation of therapy. The authors
hypothesized that this result was due to increased mono-
cyte activation in this particular patient, arguing for con-
sideration of choosing therapy tailored to distinct
histopathological or immunohistochemical features.
Treatment with external beam radiation therapy
(EBRT) has been described as a palliative treatment for
pain associated with ECD, however the duration of relief
is demonstrated to be limited.22
Our reviewed cases
included 6/19 patients receiving EBRT to the orbits for
treatment of their disease with total doses ranging from
18 to 60 Gy.7−10
All cases failed to demonstrate durable
improvement of symptoms or significant prevention of
disease progression. Notably, two of these cases resulted
in the development of marked, bilateral radiation retino-
pathy after orbital EBRT with permanent secondary loss
of vision.10
Our patient received 20 Gy of radiation
therapy to both orbits prior to transfer into our care
without improvement in her condition and with even-
tual progression of vision loss.
Surgical treatment options include mechanical debulk-
ing of intraorbital masses and orbital decompression. Of
the reported cases, 5/19 described partial or total resec-
tion of orbital masses.1,2,8,11
Three reported cases utilized
surgical decompression for alleviation of orbital mass
effect in addition to systemic therapy. 5,7,9
Our patient
also underwent bilateral orbital decompression without
significant improvement in her vision and with eventual
progression of her orbital disease. Review of the outcomes
in the 9 patients who underwent surgical debulking or
orbital decompression revealed improved pain in one
case11
but overall poor response and continued progres-
sion in 8 cases despite further attempted systemic treat-
ment. The best therapeutic outcome and symptom
improvement was found instead in the patients receiving
aggressive medical systemic treatment with corticoster-
oids, chemotherapy, or immunomodulatory therapy.3,4,6
-
6,9,14
Our patient declined further systemic treatment.
Conclusions
Erdheim-Chester disease with orbital involvement is a rare
condition with challenging management. Despite this rar-
ity, ECD should be kept in the differential diagnosis for

7. patients presenting with bilateral proptosis and orbital
masses, particularly in the setting of associated periorbital
xanthelasmas and other common systemic manifestations.
Although not well defined in the literature, overall survival
in patients with ECD appears to be correlated to the extent
of organ involvement.13
Consequently, early diagnosis of
patients presenting with orbital manifestations may lead to
earlier intervention in hopes of slowing systemic progres-
sion. The few reviewed cases in this series with reported
orbital or systemic disease stabilization or improvement
showed no clear, discernable temporal relationship
between ophthalmic manifestations, systemic manifesta-
tions, timing of treatment, and outcome. Importantly,
patients may present with ophthalmic signs and symptoms
as the first expression of this disease, making the ophthal-
mologist an important player in disease recognition.
Our patient and 13/19 literature cases (68%) report
the definitive diagnosis of ECD as either dependent on
or greatly helped by orbital findings and biopsy.
Unfortunately, despite varied, aggressive medical and
surgical approaches, only 10/19 reported cases (53%)
demonstrated improvement or stabilization of ophthal-
mic and orbital morbidity. Although disease progres-
sion and unfavorable visual outcomes occur in many
patients, systemic treatments and surgical intervention
may still be considered to improve ophthalmic symp-
toms and quality of life.
