Case Report
An 8-year-old boy presented to o ur outpa tient
clinic with a two-da y history of a m ildly pruritic
disseminated eruption. He had been treated
with steroids for six months for nephrotic syn-
drom e. Four mo nths prior to h is admission, he
had discontinued the intake of corticosteroids.
H e received o ne d ose of synth etic hepatitis B
(G enH evac B Pasteur, Pa steur Mrieux, Lyon ,
France) and polyvalent pneumococcal vaccine
(P neum o 23, Pasteur Mrieux, Lyon , France) 15
days prior to his admission. There had been no
drug in take during the previous four mon ths.
On physical examinat ion, the pat ient ap-
peared well. There were multiple, erythema tous,
oval, papulosqua mous lesions distributed o n th e
trunk and extremities, many of which ha d pe-
ripheral scales (Fig. 1). The long axis of each le-
sion was parallel to skin lines, giving the firtree d istribution pa ttern, which is chara cteristic
of pityriasis rosea. Examina tion o f mucosa an d
nails revealed no abnormalities. When ques-
tioned about prodromal symptoms for viral in-
fections, the patient denied any history of pre-
ceding illness. In vestigation of scrapin gs using
potassium hydroxide failed to show any evi-
dence of fun gal infection.

Pityriasis Rosea-Like Eruption Due to Pneumococcal
Vaccine in a Ch ild with Nephrotic Syndrome

Abstract
A pityriasis rosea-like eruption can occur a s a con seq uence o f treatm ents with go ld co m-
pounds and capto pril. It has rarely been repor ted to have an association with vaccination s
such as smallpox, BCG , hepatitis B, an d d iphtheria to xoid. It h as not previously been d oc-
umented to d evelop after pneum ococcal vaccination. We repor t a case of pityriasis rosea-
like eruption that developed fo llowing pn eumoco ccal vaccination in a child with nephrot-
ic synd rome.

erythrocyte sedimen tation rate were all nega tive
or within normal limits. The skin biopsy showed
a mononuclear perivascular infiltrate in the
upper dermis, which invaded the epidermis fo-
cally. In the epidermis, there were spongiosis,
patchy parakeratosis, and irregular acanthosis.
Scattered extravasated erythrocytes were seen in
the papillary dermis (Fig. 2). These anamnestic,
clinical and h istopath ologic find ings verified the
diagnosis of pityriasis rosea-like eruption .
The patient was treated symptomatically with
oral loratadine an d topical steroid, and the le-
sions disappeared within two weeks. The patient
received only two doses of hepatitis B vaccine
one month and six months after the first dose.
Recurrence of eruption was not seen following
these vaccinations.
Discussion
Pityriasis rosea is a unique disorder thatusually begins as a single, large, round or
oval pinkish patch known as the herald
pat ch. This is followed in about 2 weeks by a
blossoming of small, flat , round or oval,
scaly patches of similar color, each with a
central collarette scale, usually distributed
in a fir tree pattern o ver the trunk and , to
a lesser degree, the extremities. However, in
dr ug-ind uced p ityriasis rosea, th e her ald
patch is usually absent, an d th e eruption will
often no t follow the classic pattern . Pityriasis
rosea-like eruptio ns h ave been report ed
with ca ptopril, metronida zole, isotretinoin ,
D-penicillamin e, levamisole, bismuth , go ld,
barbitura tes, ketotifen, clonidin e, arsenic,and certain vaccinations such as smallpox,
BCG , and diphth eria toxoid (13). A single
case has been reported with hepatitis B vac-
cine (4). The literature do es not include
an y men tion of a p ityriasis rosea-like erup-
tion as a side effect of pneumococcal vacci-
nation.
In our case, the eruption was most likely
caused by pneumococcal vaccine for several
reasons: (i) there was a strong corr elation
between th e time course of th e reaction an d
the administration of pneumococcal vac-
cine, (ii) no recurrence of eruptions was
seen after second an d third do ses of vacci-
na tion when th e patient received hepatitis B
alone, and (iii) the ab sence of herald patch
in our case just like in most of the drug in-
duced pityriasis rosea ca ses.
Pneumococcal vaccine is occasionally
given to patien ts with a risk of immun e defi-
ciency. In ad dition to preservatives an d ad ju-
vant agents, it contains a ba cterial an tigen
with a po lysaccha ride structure. Cutaneo usside effects of this vaccine are not frequent.
Reports have been published describing
Sweets syndrome (5), acute exanthematous
pustular dermatit is (6) and keratoacan-
thoma (7) after pneumococcal vaccination.
Moreover, Kikuchi et al. reported a case of
generalized eruption and nephrotic syn-
drom e following the pn eumococcal vaccina-
tion, and blamed th e cellular immune reac-
tion on the vaccine (8).
We are n ot a ware of a ny case of an associ-ation between P R and nephrotic synd rome
in the literature and do not know if, in our
patient, it was fortuitous or not. In fact ,
pityriasis rosea is not an unco mmo n d isease
and may coincide by chan ce with a num ber
of internal disorders. Nevertheless, both
nephrotic syndrome and pityriasis rosea are
known to be induced by immune mecha-
nisms or infectious agents similarly. In the
pathogenesis of both diseases, the role of T

cell-mediated hypersensitivity is stressed
owing to th e fact that the population of T
lymph ocytes increases in the glomeru li in
neph rotic synd rome and in the lesiona l skin
in pityriasis rosea (3, 9). In addition to this,another finding to support the coexistence
of both diseases is the higher occurrence of
the prevalence of allergic symptoms in the
patients with n ephrotic synd rome (10). So,
the un derlying cause of eruption in o ur case
could be a bacterial antigen in pneumococ-
cal vaccin e itself or T cell-med iated patho lo-
gy.
Our case is the first from two points of
view: (i) it occurred following the adminis-
tration o f pneumo coccal vaccine, an d ( ii) it
had an association with nephrotic syn-
drome.
