What causes brownish black blotches to on skin on upper arm near shoulder?

A doctor has provided 1 answer

Bruises: These are hemorrhages underneath your skin resulting from rupture of fragile dermal vessels due to vitamin deficiency or trauma or perhaps even due to blood coagulation factor deficiency. If these bruises are localized and disappear in a few days, they are probably due to trauma. If they are generalized, recurrent and persistent, i suggest you see your doctor for further examination and testing.
