The association of fibrous dysplasia and intramuscular myxoma is a rare disease known as Mazabraud's syndrome. Both lesions tend to occur in the same anatomical region. The relationship between fibrous dysplasia and myxoma remains unclear, where an underlying localized error in tissue metabolism has been proposed to explain this occasional coexistence. Another example of this syndrome in a 52 year-old woman is reported. The patient presented with a soft tissue mass at the anteromedial mid part of the left thigh. After excision of the mass, three separate bone lesions were detected in her control MRI. The soft tissue mass was misdiagnosed as liposarcoma in another center, and the bone lesions were interpreted as metastasis. The hypocellularity and the indistinct vascular pattern of the lesion were consistent with myxoma. The Jam-Shidi needle biopsies of the osseous lesions were diagnosed as fibrous dysplasia. The recognition of this entity is important for appropriate management of the patient. Patients with soft tissue myxomas should be thoroughly examined for fibrous dysplasia. The greater risk of sarcomatous transformation in fibrous dysplasia with Mazabraud's syndrome should also be kept in mind.

Although there was less adhesion formation with PTFE and oxidized cellulose, PTFE not only impaired the tensile strength, but also induced fibrosis and inflammation. An oxidized cellulose adhesion barrier can be safely used in incisional hernia repair to prevent intra-abdominal adhesions.

Malignant struma ovarii is a rare form of ovarian germ cell tumors. Because of its rarity, diagnosis and management of the tumor has not been clearly defined. A 52-year-old female with follicular variant of papillary carcinoma arising in struma ovarii is presented. There was no evidence of clinical malignancy or metastases. However on the basis of histopathologic findings, the case was diagnosed as malignant struma ovarii. It was accepted as stage Ia tumor and no other treatment was considered after radical excision. Due to its fairly good prognosis, surgical excision has been the preferred treatment for those who do not have disseminated disease. Nevertheless, long-term follow-up is necessary to determine the course of the disease.
