ABSTRACT
Rhabdomyosarcoma (RMS) is the most common pediatric soft
tissue malignant tumor. It is more likely to occur in children under
5 years of age and it is most often found in the head and neck. The
presentation in the penis is extremely rare. The embryonic variety
is the most common histologic subtype. The RMS of the penis is
usually a painless mass. In some cases dysuria and priapism can
also be present. Treatment is based on surgical resection, chemotherapy
and radiation therapy.
We describe a 3 year old boy with a 6 month history of a painless
enlargement of the penis due to the presence of a mass. On its
dorsal aspect measuring 3 x 3 cm with necrotic and ulcerated
areas; it did not affect the urethral meatus. On the CT scan a
tumor on the left lateral side of the penile shaft was found, with
a diameter of 2.8 x 2.5 x 3.3 cm and a 12 cc volume. Surgical
resection of the mass was performed. The histopathologic study
reported an embryonal type RMS. The patient was treated with
chemotherapeutic agents including ifosfamide and doxorubicin,
with a favorable outcome.
