observed on the cuts from the

left kidney, peri-glom erular

and peri-tubular fibrosis, w ith

m ononuclear inflam m atory

infiltrate and few neutrophils.

T hese abnorm alities w ould

suggest an aggression to the

nephric parenchym a,

follow ed by fibrosis and a

reduction in the nephric size.

C ase 5: Instead of a w ell

defined genitalia, the fetus

had a phallic projection,

coated w ith squam ous m ucosa

and a cistic form ation covered

w ith squam ous epitheliocyte,

containing keratin.

W e identified, on the

squam ous epithelium

hyperkeratosis, irregular

acanthosis and m oderate

papillom atosis (figure 2.5 A ).

W e noticed num erous cells

w ith P N H , nuclei portraying

an increase in size, w ith light hyperchrom asia, oval, "flattened"

in som e areas, fusiform or binucleated (figure 2.5 B ). In the

subjacent conjunctive tissue the vessels presented ectasis and,

in som e areas, w ere involved by m ononuclear inflam m atory

cells.

T he ultrafine cuts of the skin in cases 1,2, and 4 show ed,

in the epiderm ic cells, viral precursors, 27 nm in diam eter

located in the nucleus; and w hole viral particles, w ith an

average diam eter of 50 nm located in the cytoplasm and

nucleus. In the tissue of the kidney (case four), viral particles

sim ilar to those of the skin w ere found located in the nucleus

and cytoplasm of the tubular epithelial cells (figure three),

different from the dense fibrillar and fibroblast population,

w here w e did not see viral particles.

(figure 2.1).

T he nuclei w ere larger than norm al for the superficial

occasionally fusiform and rarely binuclear. T he superficial

derm is show ed ectasis and slight m ononuclear inflam m atory

C ase 2: M oderate cutaneous hyperkeratoses, acanthosis,

congested vessels and surrounded by a m oderate quantity of

m ononucleated inflam m atory cells.

C ase 3: V aginal epithelium w ith hyperplasia and

cytoplasm atic vacuoles, due to glycogenic deposit. T he skin

presented slight and m oderate hyperkeratosis, m oderate and

focal acanthosis, light papillom atosis and areas w ith P N H and

oval nuclei, som etim es "flattened" or fusiform . In the derm is,

vascular ectasis and areas of light m ononuclear inflam m atory

hyperkeratosis and m oderate acanthosis, accentuated

In case 4, the presence

of peri tubular,

periglom erular

and

interstitial

fibrosis

associated

to an

inflam m atory

infiltrate,

represent

abnorm alities

that justify

the nephric decrease

in size. T he identification

of viral particles

in tubular

cells confirm s

the association

of the abnorm alities

to the H P V , how ever,

it does not m ake

possible

an etiologic

association,

since the H P V

such as, the path of

infection.

In this case

w e could

not prove

that the viruses

T he studies

that use the IH Q

techniques

to reveal

the

of H P V

antigen,

indicate

are

a

standard

of positivity

(50-54).

on the lesions

of adult patients,

P adayache

(53), in 1987, published

the results

of their

studies

on oral

papillom as.

It describes,

along

w ith

positive

and

negative

groups,

a group

w ith 9% of doubtful

cases,

w ith

cells

w ith

cytoplasm atic

im m unopositivity

exclusively

or in the nucleus

and cytoplasm .

T he

identification

of discontinued

areas

of

the nuclear m em brane,

though the possibility

of artifact should

be considered,

and

the

com plete

particles

found

in the

cytoplasm

in the cases

of congenital

vulvar

lesions,

m ay

explain

the cytoplasm atic

m arking

by im m unohistochem ical

(lH Q ), justifying

the scarce

nuclear

m arking.

In the reference

groups,

the epiderm ic

m arking

w as

only

in the

reference

that w as used show ed

the expected

nuclear

m arking.

C onsidering

that the studies

of lesions

w ere done on stillborns

and

dead

neonates,

it can

be

affi rm ed

that

the

infection

happened

intra-uterus,

though

the

hem atologic

or ascendant

could

be discussed.

T he studies about condylom a

show

that

the

evolution

is

unpredictable:

som e

cases

resolve

spontaneously,

others that

recur, and others

persist

and can

be associated

to the developm ent

of carcinom as

(28-30,43,55).

T he genital

w orts are lesions

that have been recognized

since

antiguity

and referred

to by m any

G reek

and R om an

w riters

(42). U ntil

1954 the m echanism

of transm ission

w as

still not clear, the viral etiology

w as only established

in 196842

and w as further

investigated

only after becam e

associated

to

the vul val carcinom a

(43). T he potential

of fetal infection

of

som e

viruses

is w ell know n.

T he possibility

of H P V

being

one of these viruses

has been described

in the last few years

(32-36).

In our report

of the fi ve cases of congenital

papillom as

and papillom atosis,

identified

in stillborns

and new ly

borns

dead after a short period

of tim e, during

the initial necropsy

the possibility

of a viral lesion

w as not considered,

except

in

the last case, in w hich

a necroscopy

exam

w as done in 1991.

In this w ay, it becam e

a triggering

factor for the re-evaluation

of the other cases.

T he histopathological

aspects

observed

in the lesions

that w ere studied,

correspond

and are classically

described

as

being associated

to the injection

by the H P V . In all the cases

w e observed

epiderm ic

abnorm alities,

such as, hyperkeratosis,

acanthosis,

papillom atoses

and perinuclear

haloes

sim ilar

to

the

K oylocitosis

(44-46).

In the

lesions

w e studied,

the

vacuolated

cells

show ed

aspects

very

sim ilar

to the ones

described

in the

literature,

w ith

am ple

and

w ell-defined

perinuclear

haloes,

involving

various

aspects

of nuclei:

w ith

a single

or double

nucleus,

increased

in size, oval, fusiform ,

w ith condensed

and granulated

chrom atin,

w ith central clear

areas and peripheral

chrom atin.

In

all

of

the

vulval

lesions

to

The im m unopositivity

for the L I protein of the H PV

capsid in the nucleus and cytoplasm of the epiderm ic cells of

4 of the 5 lesions studied and the identification of nuclear and

cytoplasm atic viral particles, m easuring approxim ately 50 nm ,

in the epiderm ic cells of three lesions, confirm the association

betw een the H PV and the lesions studied. H ow ever, only m ore

detailed studies w ith a greater num ber of cases can definitely

confirm the involvem ent of the H PV in the etiology of these
