Keratoderma blennorrhagicum (from kerato- 'keratinized' derma- 'skin' blenno- 'mucous' and -rrhagia 'discharge'; also called keratoderma blennorrhagica) are skin lesions commonly found on the palms and soles but which may spread to the scrotum, scalp and trunk. The lesions may resemble psoriasis.: 195 

Keratoderma blennorrhagicum is commonly seen as an additional feature of reactive arthritis in almost 15% of male patients. The appearance is usually of a vesico-pustular waxy lesion with a yellow brown colour. These lesions may join to form larger crusty plaques with desquamating edges.
