a is benign cutaneous lesion of capillaries, resulting in small marks
of red to blue color and characterized by hyperkeratosis.
corporis diffusum" refers to Fabry's disease, but this is usually
considered a distinct condition.
usually give a history of many years of a progressive appearance of
asymptomatic papules on the scrotum.
The patient may not be aware of the lesions, and bleeding (spontaneous,
after intercourse or scratching) may be the first presentation causing
the patient to seek medical help.
authors report that lesions are asymptomatic; however, a few describe
pain or itching.
Fordyce angiokeratomas appear as black, blue, or dark red, dome-shaped
papules ranging from 1-6 mm in diameter, with a mean of 3 mm. The
overlying surface may show slight scales (hyperkeratosis).
Reports suggest that in younger patients, the lesions tend to be smaller,
more erythematous, and less hyperkeratotic.
patients have larger, darker lesions (blue/black) with overlying scales
have been reported from this condition. The most significant morbidity
comes from bleeding.
can bleed spontaneously if traumatized or during intercourse. Many
of the reports describe patient concern that the lesions represent
a sexually transmitted disease.
treatments such as interventional radiology, lasers, and physical
therapy are employed to reduce the severity of the vascular lesions.
However, in some cases lasers have caused a reaction in the tissue
causing it to expand and become exposed to infection.
and grafting may be necessary to remove the lesion. Recovery time
on such an operation ranges from 3 to 12 weeks depending on location
of the graft, healing time and the possibility of complications.
of Fordyce are benign bumps composed of surface blood vessels. They
could be red, or dark blue, or purple. They usually don't hurt unless
they are rubbed or scratched and in these situations they may even
usually form in people who are around 40 or older.
from Fabry syndrome, which is caused by a genetic defect, the cause
of other angiokeratomas is unknown.
angiokeratoma of the scrotum is often a benign condition, it has the
potential to cause considerable worry and distress to patients.
management of suspected angiokeratoma is to control bleeding with
achieved, despite the evidence remaining unclear, it is important
to exclude raised intra?abdominal pressure as a cause, especially
if there are associated systemic features.
history and clinical examination of the abdomen for intra?abdominal
masses may help to exclude urinary tract tumours and hernias.
to exclude microscopic haematuria may also help.
should be examined for evidence of varicocele, often described as
a scrotal swelling mimicking a bag of worms, most evident when the
patent is stood upright.
skin should also be carefully examined for other lesions that may
be associated with angiokeratoma corporis diffusum, malignant melanoma
and melanocytic naevii.
generally respond well to local laser treatment but this treatment
may cause a reaction in the tissue.
