Arteriovenous Malformation- Malformations of
the glans penis are very uncommon in the pediatric
assembly. They are identified at birth or children
and/or parents may observe the growing lesions
with age. The phrase malformation is utilised for
developmental pathologies but also may be utilised
for lesions which develop then. Although the
malformations on the glans penis are identified by
basic personal and radiological examinations, the
lesions can pose large concern for the progeny and
parents.
This status loans itself to early diagnosis and
treatment in numerous situations. All of the
malformations of the glans penis are benign in
childhood. Although there is a likelihood for
malignant transformation in some lesions, there is
no report of malignant transformation thus far.
Herein, we report two very uncommon cases which
are arteriovenous malformations (AVM) on glans
penis.
Case Reports
Case 1
A 14-year-old male persevering and his parents
offered at urology outpatient clinic with accusations
of a purple-colored lesion on glans penis which is
about 1 centimetres in dimensions; in personal
examination, he was circumcised, penile extent was
usual, testes were well descended and usual. Pubic
hairs were glimpsed.
All of these findings were matching with his
chronological age. There was superficial and soft
consistency lesion which diameter was 1
centimetres with palpation on glans penis at the
level of 12 o’clock [Figure 1]a. The initial diagnosis
of the lesion was a vascular malformation. In
radiological assessment, the diameter of the
superficial vascular lesion was 1 centimetres and
the lesion was 4.1 mm in deepness [Figure 1]b and
c. The surgical excision was presented and the
report of the histopathology was AVM [Figure 1]d
and e.

colored Doppler ultrasound, source of lesion is
vascular and vascular discoloration can be
discerned. (d) After surgical excision of lesion. (e) In
histopathology, vascular units attach each other
with mature epithelial units and venous dilatation
with arterial hypertrophy is discerned. (f) Vascular
malformation on glans penis was pulsatile in
personal and radiological examinations
Case 2
A 2-year-old male persevering and his parents
offered to the urology outpatient clinic with
accusations of a lesion which has been present
since birth on glans penis and also involving the
genital locality. On physical examination, he was
uncircumcised and his penile length and testicles
were usual. A pulsatile vascular malformation was
on glans penis. In radiological written test, there
was an excessive vascularization in lesion and
these findings were matching with AVM [Figure 1]f.
The surgical intervention was not recommended for
that lesion. broad excision, laser, and sclerotherapy
were recounted as a recommended remedy choices
in the future. Additionally, normal follow-up was
suggested in outpatient clinic.
Discussion
There are many glans penis malformations that
have been recounted in literature, though there has
been no comprehensive study. Up to now, 142
cases have been described in the publications. In
those 142 described situations, cystic lesions were
in 62 (44%), vascular malformations were in 34
(24%), dermatological lesions were in 23 (16%),
infectious lesions were in 20 (14%), and neurogenic
lesions were in 3 (2%) situations. We would like to
report two cases from two different clinics with
vascular malformations of glans penis.
