Sarcoidosis

Skin symptoms - Sarcoidosis can appear as a collection of tender, red bumps called erythema nodosum. It also can occur as a scaly, purplish discoloration on the nose, cheeks and ears, called lupus pernio. Less often, sarcoidosis causes cysts, pimples or disfiguring overgrowths of skin. In many cases, the disfiguring overgrowths develop in areas of scars or tattoos.

Eye symptoms - These include red eyes, eye pain and sensitivity to light.

Heart symptoms - These include irregular heartbeat and heart failure.

Other symptoms - A person may have paralyzed facial muscles, seizures, psychiatric symptoms, swollen salivary glands or bone pain.
