What should you know about cutaneous sarcoidosis symptoms?

Skin sarcoidosis can produce smooth or scaly raised areas, reddish-brown or darker patches, small papules, or thickening around an old scar. Lesions may be painless, itchy, tender, or sensitive to touch. A tender eruption on the shins is one possible pattern, while lesions on the face may affect appearance without causing discomfort. Symptoms outside the skin can include persistent cough, breathlessness, sore or light-sensitive eyes, joint discomfort, or unusual tiredness. These features are not specific enough to diagnose sarcoidosis, so an examination is useful.

Record when each skin change started and whether it follows sun exposure, injury, or a new medicine. Take clear photographs if the appearance comes and goes, and list any eye, chest, joint, or general symptoms. A clinician may examine the entire skin surface and recommend a biopsy or other checks. For confirmed disease, local lesions may be treated with an Intralesional Steroid Injection Into The Skin, while more extensive involvement may prompt discussion of Oral Corticosteroid Treatment.

Seek urgent care if you develop sudden visual change, severe eye pain, marked breathing difficulty, chest pain, or collapse. Arrange prompt review when a skin lesion grows quickly, opens, bleeds, becomes very painful, or is accompanied by fever or feeling acutely unwell. The urgency comes from the symptom pattern and its effect on health, not from assuming that every skin mark has the same cause.

Which of my symptoms fit skin sarcoidosis, and which need another explanation? Is a biopsy appropriate? Should my eyes or lungs be checked? What changes should make me contact the clinic sooner?
