Kawasaki disease is a multi system disorder with varying clinical expressions. This disease
is an acute systemic vasculitis of unknown etiology that has recently recognized as a leading
cause of acquired heart disease in children of many developed countries. We describe an
unusual instance of hair loss in a patient with Kawasaki disease.
A 26 months old boy developed prolonged high fever, bilateral conjunctival infection,
arthralgia and erythromatosis skin rash. He was admitted to the hospital with the diagnosis of
Kawasaki disease. Laboratory results included an erythrocyte sedimentation rate (ESR) above
100 and platelet count > 1000,000. The patient developed acute and unprovoked scalp hair
loss. He was treated with intravenous immunoglobulin (IVIG) 2 g/kg and aspirin 100
mg/kg/day with complete improvement of signs and symptoms.
This report documents hair loss as an uncommon presentation of Kawasaki disease.

Kawasaki disease (KD) is a systemic vasculitis of
childhood with a predilection for the coronary arteries.
It is the predominant cause of pediatric acquired heart
disease in developed countries. The aetiology of KD
remains unknown.1 The disease can present with
protean clinical manifestations which include high
grade fever (for at least 5 days), rash, redness of the
lips and a typical strawberry tongue, cervical lymph
node enlargement (often unilateral), swelling over the
hands/feet and, later a characteristic peripheral
desquamation over the fingers and toes. These clinical
features appear sequentially and the findings may
change from day-to-day.2

Other manifestations may include diarrhea,
vomiting, abdominal pain, hydropse of gallbladder,
myositis, ulcerative stomatitis, aseptic meningitis,
cranial or peripheral nerve palsies, transient arthritis
Cardiac involvement is the most important
manifestation of Kawasaki disease.2 We describe a case
of diffuse hair loss in a 26 month old boy with KD.
A 26 months old well-nurished boy from town of
Yasuj without any significant past history developed
high and constant fever, irritability and body pain since
12 days prior to admission and was treated with
antibiotic and antipyretic without any response. 2-3
days later. He developed a confluent, erythrematosis,
papular rash over the face, trunk and extremities.
His lips became red and swollen. Bilateral
nonsupporative conjunctival injection was also noted.

sedimentation rate (ESR) of 70mm/h, which increased to
108 mm/h and white blood cell count of 15900 that
increased to 22500/mm. Platelet count was 750,000
initially and increased to 1100,000/mm (in the course of
hospital and after treatment with IVIG). Blood, throat,
stool and urine cultures

of prolonged fever and four main diagnostic criteria.

Figure 1. Hair loss in a patient with Kawasaki disease.
The patient developed acute and diffuse scalp hair
loss on admission and on the 6th day of fever. Hair loss
was generalized and progressive with approximately
40-50 hairs loss in one hour (Figure 1).
He was treated with intravenous immunoglobulin
(IVIG) 2 g/kg and aspirin 100 mg/kg with improvement
of signs and symptoms. The hair loss stopped
completely 12 hours after IVIG.
KD is the second most common vasculitic disorder
of children. KD causes a severe vasculitis of all blood
vessels but predominantly affects medium sized artery
with predilection for coronary arteries.2
In the most severely affected vessels, inflammation
involves all three layers of vascular wall with
destruction of the internal elastic lamina. Thrombi may
form in the lumen and obstruct blood flow.3 Vasculiltis
in KD may rise to multisystem vasculitis syndrome e.g:
ocular cellutites,4 smooth
consiousness disorder6 and facial nerve paralysis.7
The diffuse loss of hair can occur following high
fever, severe illness or stress. Because in this condition
all the follicles of hairs from anagen phase enter
telogen and these hair are therefore shed, but this
condition is commonly seen 4-9 months after stress .8
This rare condition may be attributed to vasculitis,
stress or heightened inflammatory response. KD with
involvement of vasculature of different organs can
produce different signs and symptoms. Therefore with
presence of principle criteria of KD, this uncommon
presentation should not make the physician confused.
