Suyama L, Itoh A. BMJ Case Rep 2017. doi:10.1136/bcr-2017-220770 Description Parosteal lipoma is a rare benign tumour that is composed mainly of mature adipose tissue, and is contiguous to the periosteum of the underlying bone. Most parosteal lipomas are asymptomatic, but some may present motor and/or sensory deficits. A woman was seen in our office complaining a left breast tumour. The woman f...

Low-grade surface tumours of bone may theoretically be treated by hemicortical resection, retaining part of the circumference of the cortex. An inlay allograft may be used to reconstruct the defect. Since 1988 we have performed 22 hemicortical procedures in selected patients with low-grade parosteal osteosarcoma (6), peripheral chondrosarcoma (6) and adamantinoma (10). Restricted medullary invo...

The case of a 34-year-old man with a fast growing hard lump on the fourth digit of the right hand is presented. Radiography and MRI of the finger showed the radiologic characteristics of a bizarre parosteal osteochondromatous proliferation. Pathologic analysis confirmed the radiologic diagnosis.

PURPOSE To determine the response and toxicity of docetaxel in recurrent osteosarcoma and related spindle cell tumours of bone. PATIENTS AND METHODS Fourteen patients, 10 males and four females, were enrolled, median age 30.5 years (range, 17-46). Diagnosis was: conventional osteosarcoma, 12 patients; periosteal osteosarcoma, one patient; and malignant fibrous histiocytoma of bone, one patien...

BACKGROUND Nowadays, the results of the management of malignant bone and soft-tissue tumors have been dramatically improved because of the advance in imaging, chemotherapy, radiation therapy, and surgical techniques. Patients can have longer survival times with limb-salvage surgery. Several techniques of reconstruction have been advocated and gained more popularity following malignant tumor res...

Osteosarcoma (OS) is a common primary malignant tumor of bone that produces osteoid matrix. According to the World Health Organization, OS of bone is classified into eight subtypes with distinct biologic behaviors and clinical outcomes: conventional, telangiectatic, small cell, low-grade central, secondary, parosteal, periosteal, and high-grade surface. Imaging plays a crucial role in the diagn...
