Mastocytoma

Mastocytoma is a solitary, brown-pink plaque with poorly demarcated borders on the thigh of a young child; the lesion was tan and flat prior to stroking (positive Darier's sign). When stroked very vigorously, a blister developed. Mast cell tumors can involve the skin, subcutaneous tissue, and muscle tissue. Also called mast cell tumor.

Greater than 50 percent - onset by age 2. Children with solidary mastocytoma rarely worsen after 2 months without new spots. All systemic pts often have prolonged bleeding.

Mastocytoma are familial rare but happens. Most lesions present in early childhood are gone by age 10.

Treatment of Mastocytoma

If the mastocytoma is causing a lot of itching, this can often be relieved with oral antihistamines. No other treatment is necessary as mastocytomas usually disappear as the child grows older.
