S-100, also S100, is a commonly used immunostain. It marks nerves.
Positive
- Nerves.
- Schwannoma.
- Mature adipose tissue.
- Interdigitating dendritic cells.[1]
- Langerhans cell histiocytosis.
- Rosai-Dorfman disease.
- Chordoma - also keratin positive (AE1/AE3, CK19, CAM5.2).[2]
- Granular cell tumour.
- Nodal nevus.
Malignant tumours
- Malignant melanoma - almost 100% sensitive.
- Malignant peripheral nerve sheath tumour.
- Clear cell sarcoma.
- Mammary analogue secretory carcinoma.
