- Black/blue/brown spots or moles, on the skin and lining of the mouth
- Skin problems
- Redness, bumps, or irritation on the skin

Q.
Sudden Red Spots? Why Your Skin is Forming Cherry Angiomas & Medical Steps
A.
Sudden small bright red skin spots are most often cherry angiomas, benign clusters of blood vessels that become more common after 30 and can be influenced by genetics and hormonal shifts. There are several factors to consider. See complete details below. See a clinician promptly if many appear at once, a spot grows or changes color, bleeds frequently, hurts, or you have systemic symptoms, and avoid home removal since doctors can confirm the diagnosis and remove them safely with options like laser or cautery; key red flags and next-step guidance are outlined below.

Q.
Is that red spot a hemangioma? Why it grows and the medical steps to treat it.
A.
A red spot can be a benign hemangioma, a buildup of extra blood vessels that in infants often appears in the first weeks, grows for a few months, then slowly shrinks, while adult cherry angiomas are small, bright red dome bumps that usually persist. There are several factors to consider; see below to understand more. Most need only watchful waiting, but lesions that threaten vision, breathing, or feeding, or that ulcerate, bleed, or grow quickly may be treated with beta blockers such as oral propranolol or topical timolol, laser therapy, less often steroids, and occasionally surgery. Diagnosis is usually by exam with imaging if needed, and important details that could change your next steps are explained below.
