Buschke-Ollendorf syndrome is a rare condition characterized by uneven sclerotic, osseous formations seen on X-ray (osteopoikilosis) and fibrous skin papules (dermatofibrosis lenticularis disseminata). We report an 82-year-old man with this syndrome. Awareness of the condition is important to avoid misdiagnosis and hazardous management designed for other disorders, such as prostatic metastases.
