Angiokeratoma is a benign cutaneous lesion of capillaries, resulting in small marks of red to blue color and characterized by hyperkeratosis. Angiokeratoma corporis diffusum refers to Fabry's disease, but this is usually considered a distinct condition.
Presentation includes telangiectasia, acanthosis, and hyperkeratosis.
Presentation can be solitary or systemic.
In some instances nodular angiokeratomas can produce necrotic tissue and valleys that can harbor fungal, bacterial and viral infections. Infections can include staphylococcus. If the lesion becomes painful, begins draining fluids or pus, or begins to smell, consult a physician. In these instance a doctor may recommend excision and grafting.
Angiokeratomas characteristically have large dilated blood vessels in the superficial dermis and hyperkeratosis (overlying the dilated vessels).
Scrotal angiokeratoma; visible large dilated blood vessels and hyperkeratosis
Scrotal angiokeratoma (Fordyce type); multiple papules made by dilatated capillaries
Scrotal angiokeratoma (Fordyce type); dilated cavernous capillaries, acanthosis
Scrotal angiokeratoma (Mibelli type); blood vessels close to the epidermis
Angiokeratoma (Mibelli type)
Due to the rarity of different types of vascular conditions, angiokeratomas may be misdiagnosed. A biopsy of the lesion can produce a more accurate diagnosis.
Angiokeratoma may be classified as:
Outpatient 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. Excision 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.
