[Osteopecilia associated with psoriatic arthritis]. / Ostéopoécilie associée à un rhumatisme psoriasique.

Osteopecilia is a benign and rare condensing osteopathy. Its association with inflammatory rheumatism is very rare. We here report the case of a 25-year old patient with skin psoriasis, presenting with groin pain of inflammatory origin. Physical examination showed limitation of hip motions, lower limb-length inequality and pain on right sacroiliac mobilization. Laboratory tests showed inflammatory syndrome and negative immunological assessment. The radiograph of the pelvis revealed osteopecilia associated with destructive coxitis. CT scan of the pelvis showed coxitis and osteopecilia associated with bilateral sacroiliitis. The diagnosis of psoriatic arthritis associated with osteopecilia was retained. The patient was treated with methotrexate and NSAIDS. Osteopecilia usually is unexpectedly detected. Diagnostic radiology is essential to avoid unnecessary explorations and treatments.

Osteopoikilosis: what does the rheumatologist must know about it?

Osteopoikilosis (OPK) is a rare, benign, and asymptomatic bone dysplasia that is developed during childhood and persists throughout life. This condition is generally found incidentally on plain radiographies made by other reasons. The main differential diagnosis is osteoblastic metastasis. So, OPK must be in differential diagnosis when bone lesions are identified on plain radiograph to avoid alarming the patient with more serious disease and misdiagnosis. In this paper, we review the clinical manifestation, pathophysiology, diagnosis, and treatment of OPK.

A rare benign disorder mimicking metastasis on radiographic examination: a case report of osteopoikilosis.

Osteopoikilosis (OPK) is a rare, autosomal dominant bone disorder, characterized by multiple, discrete round or ovoid radio densities scattered throughout the axial and appendicular skeleton. OPK is usually asymptomatic but rarely there may be slight articular pain and joint effusions. OPK is generally diagnosed incidentally on radiographic examinations and may mimic different bone pathologies, including bone metastases. Radionuclide bone scan has a critical role in distinguishing OPK from osteoblastic bone metastases. In this case report, we present a young man with right hip pain due to OPK, whose plain radiogram and computerized tomography findings thought cancer metastasis.

Coexistence of osteopoikilosis and discoid lupus erythematosus: a case report.

Osteopoikilosis is an uncommon, benign sclerosing bone dysplasia characterised by typical roentgenographic findings and usually seen in patients with dermatological problems. We report a case of osteopoikilosis and discoid lupus erythematosus presenting with skin and mucosal involvement, an association that has never previously been reported. We also discuss the differential diagnosis and the clinical pathologies accompanying osteopoikilosis in the literature.
