BACKGROUND: Osteopoikilosis (OPK) is an extremely rare benign condition with sclerosing bony dysplasia and multiple benign enostoses. OPK is usually asymptomatic and is typically an incidental finding on imaging studies for unrelated conditions.
METHODS: We presented a case of OPK in a 7-year-old female with hallux valgus, shortening and deformity of second and third metatarsals in the right foot. These abnormalities were observed on clinical findings with X-ray imaging, and osteopoikilosjs was confirmed by histopathology. The deformities were treated with surgical intervention, and the patient\'s condition was followed for 3 months until the patient walked and removed the gypsum.
CONCLUSIONS: OP is a rare, benign disease that rarely causes bony deformities. It is diagnosed clinically and radiographically, so that the deformities are treated only surgically. Follow-up is necessary to assess the movement of the limb.
CONCLUSIONS: The distinctive thing that can be added to the medical literature is that it is possible for osteopoikilosis to cause bone deformities at an early age.

Osteopoikilosis (OP) is a rare autosomal dominant sclerosing bone disease, caused by heterozygous mutations in the LEMD3 gene. It is characterised by numerous focal lamellar bone compact deposits in the spongiosa. In this case report, we describe a famliar case of OP and review the literature.
