Abrikossoff's tumor. Light micrograph of a section through skin affected by an Abrikossoff's tumour (granular cell tumour), showing granular cells with clear cytoplasm, characteristic of the Abrikossoff tumour (bottom, light pink). The epidermis can be seen at top (dark pink). This rare tumour is normally benign (non-cancerous), usually appearing in the skin and arising either from nerve cells or the Schwann cells that form the sheath of nerve fibres. Most of these tumours are surgically excised and do not recur. Around half occur on the head and neck. Magnification: x560 at 10 centimetres wide.
