Angiokeratomahttps://en.wikipedia.org/wiki/Angiokeratoma
Angiokeratoma is a benign cutaneous lesion of capillaries, resulting in small red‑to‑blue macules and characterized by hyperkeratosis. Multiple angiokeratomas on the trunk in young people may indicate Fabry disease, a genetic disorder associated with systemic complications.

Because they are rare, angiokeratomas may be misdiagnosed as melanoma. A biopsy can provide a more accurate diagnosis.

  • Atypical case ― multiple Angiokeratoma; Most Angiokeratoma are single lesions.
  • It resembles melanoma in shape but differs because it feels soft and pliable. Angiokeratoma lesions are typically smaller than shown in this picture and usually appear as a single lesion.

Angiokeratomas are vascular neoplasms with hyperkeratotic red to black papules and plaques, which may present as solitary or multiple lesions with variations in color, shape, and location. Successful treatment not only involves improvement of these symptoms but also cosmetic improvement. This report reviews 2 cases of cutaneous angiokeratoma treated with surgical excision and a 595-nm pulsed dye laser (PDL) in which the patients showed improvement of symptoms and cosmetic appearance. There are various types of angiokeratomas, and their extent, size, condition, and symptoms are different. Therefore, lesion-specific combined treatments may yield better results.
