Mastocytoma, a form of mastocytosis, is a single, benign skin tumor and is often called a mast cell tumor or a mast cell neoplasm.
They often form on the torso, neck, or arms. Mastocytomas generally appear in infants/young children.
Mastocytomas are benign and highly survivable.
Signs & Symptoms
The most common symptom is a raised pimple-like growth.
COMMON SIGNS & SYMPTOMS
- Red/pink/yellow bumps from 1-5 centimeters in diameter on the skin. Rubbing mastocytomas causes reddening, swelling, blistering, and itching.
A skin biopsy is the only conclusive way to diagnose a mastocytoma.
Most patients do not receive treatment; mastocytomas often disappear with age.
COMMON TREATMENT OPTIONS
- Oral Antihistamines: relieve itching
- Surgical Excision
