ABSTRACT
True hermaphrodite is one of the rarest
variety of disorders of sexual differentiation (DSD) and represents only 5%
cases of all. A 3-year-old child presented with left sided undescended testis
and penoscrotal hypospadias. Chordee correction was performed 18 months back,
elsewhere. At laparotomy Mullerian structures were present on left side. On
right side testis was normally descended into the scrotum.

INTRODUCTION
True hermaphrodite or
ovo-testicular disorder of sexual differentiation (OVO-DSD) is one of the rarest
variety of all inter sex anomalies. In about 90% of cases, patients have 46 XX
karyotype. Rarely, 46 XY/46 XX mosaicism may occur. There have been reports of
46 XY karyotype [1].
In this condition gonads are asymmetrical having
both ovarian and testicular differentiation on either sides separately or
combined as ovotestis. In ovotestis, testis is always central and ovary polar in
location [2]. Testosterone and Mullerian inhibitory substance (MIS) are either
normal or low. However for final diagnosis there must be histological
documentation of both types of gonadal epithelium [3]. We are
reporting this case for the reason of extreme rarity of this disorder of sexual
differentiation with 46 XY Karyotyping.
CASE
REPORT
A 3-year-old patient presented in outpatient department of Sheikh
Zayed Hospital Rahim Yar Khan. This child was reared as male and chief complaint
was the absence of left testicle in the scrotum along with passage of urine from
an abnormal urethral opening at the junction of penis and scrotum. A surgical
procedure was performed at 18 months of age to straighten the penis and few
injections (testosterone) were given to increase the size of penis, although no
record was available.
On examination left testicle was not palpable in
the scrotum or inguinal canal. Right testicle was palpable in the scrotum and
was of adequate size according to the age of child. Phallus examination showed
scar mark on the ventral surface of penis and meatal opening was present at
penoscrotal junction. Penis was about 4 cm long with 1.5 cm diameter. All
routine investigations were within normal range. Testosterone level was 2.50
micro gram/ dl (normal value 30-50). Barr body test was negative. Karyotyping
was 46 XY. Ultrasound report showed left undescended testis which was not
visible in inguinal canal or abdomen. No Mullerian structures were noted. A
diagnosis of left undescended testis (UDT) with penoscrotal hypospadias was
made.
Abdominal exploration for UDT revealed Mullerian structures (ovary,
unicornuate uterus, fallopian tube and cervix) on left side (Fig. 1, 2). On
Right side vas and vessels were found into deep inguinal ring. After counseling
with the parents it was planned to rear this child as male due to predominant
male phenotype. The persistent Mullerian structures were excised and sent for
histopathology. Biopsy was taken from Right testicle in order to find any
dysgenesis or ovotesticular tissue. Biopsy report confirmed ovary, fallopian
tube and uterus on left side. Right testicular biopsy showed normal histology
with semineferous tubules without any dysgenesis or ovarian
tissue.
DISCUSSION
Disorder of sexual differentiation is the terms used for a child born
without clear male or female phenotype. The term “hermaphrodite” is derived from
Greek mythological God “Hermaphroditos” son of Hermes and Aphrodite, whose body
after being merged with nymph Salmakis assumed a more perfect form with both
male and female attributes [4].
Proper gender assignment to a neonate
born with DSD is a social emergency of the newborn period. Infants and children
born with DSD pose a diagnostic and therapeutic challenge to the clinicians.
Success depends upon rapid and precise diagnosis, appropriate gender assignment,
proper medical therapy and meticulous surgical technique. [5].
The causes
of true hermaphroditism remain enigmatic and the commonest presentation is an
abnormal external genitalia ranging from normal male to normal female. In
many of these cases such distinction may not be present and chordee, hypospadias
and cryptorchidism may be noted. Similar picture is found in our case.
Other presenting symptoms are hematuria, amenorrhea, lower abdominal pain and
inguinal hernia [6-8].
Documentation of location of gonads is important.
In true hermaphrodites gonads are always asymmetrical with predominant testis
descends and predominant ovary lies in the abdomen above the external ring as
noted in index case. On the basis of location of gonads and histology these
patients are classified as:
·Lateral: Testis and contralateral ovary (30%).
·Bilateral: Testicular and
ovarian tissue identified on both sides, usually as ovotestis (50
%).
·Unilateral: Ovotestis on one side and testis or ovary on other side
(20%).
Our patient was of lateral variety in which testis was on right side
and ovary on left side. The choice of rearing hermaphrodite as male or female
sex is governed by phallus size [9]. In our patient penis was of adequate size
thus plan in consultation with parents was made to rear him as a male. All
female structures were thus removed. A repair of hypospadias will be performed
in the next stage. Prosthesis can be placed in left hemiscrotum for
psychological comfort.
True hermaphroditism is rarely associated with
gonadal tumours, unlike in mixed gonadal dysgenesis, where the presence of a
dysgenetic gonad predisposes to gonadal malignancy. However a few cases of
malignancies like dysgerminoma and gonadoblastoma have been reported in true
hermaphroditism [10]. Hence this patient will require close follow up to
diagnose any malignancy arising in his remaining testis. Since the incidence of
gonadal malignancy is low, estimated at 4.6 %, [1] prophylactic removal of his
remaining testis is not justified.
Our case was unique as chromosomal
analysis was 46 XY, which is very rare in a case of true hermaphrodite
DSD.
