Osteoblastoma is a rare bone tumor which is mostly found in the vertebral column and long bone. We describe a 59-year-old woman with osteoblastoma in the right fifth posterior segment of the rib, whose presenting symptoms were right back pain for two years and awakened at night. Chest computer tomography (CT) and thoracic spine magnetic resonance (MR) imaging findings included an expansile lesi...

BACKGROUND Xanthogranulomatous osteomyelitis often presents as a severe chronic inflammation associated with pain, fever, and leukocytosis. It may mimic carcinoma in the involved organs. CASE PRESENTATION A 50-year-old post-menopausal woman presented with a 2 year history of increasing swelling in the extensor aspect of her right forearm. Plain X-ray revealed an ill-defined expansile osteolyt...

Infiltrating syringomatous adenoma of the nipple is a benign lesion initially reported by Rosen in 1983. Infiltrating syringomatous adenoma of the nipple is a rare but distinct benign clinical entity affecting the breast. It is similar histologically to a syringoma, a benign tumour originating in the ducts of the dermal sweat glands, and importantly needs to distinguished from a tubular carcino...

Abstract We present the case of a child with rare benign tumour temporal bone. A nine-month-old girl was referred to her local paediatric hospital painless right-sided, post-auricular swelling increasing in size preceding two months. On examination there 2x2cm mass overlying bone posterior right ear. The firm, immobile, non-tender and well circumscribed. Ultrasound demonstrated 1.9cm subcuticul...

fibrous dysplasia of the bone (fdb) is a common, genetic, developmental disorder with a benign course. fdb can be seen anywhere throughout the skeleton. it is usually asymptomatic and found incidentally on imaging studies that are performed for other purposes. although whole body 18 f-flourodeoxyglucose pet/ct (fdg pet/ct) is widely used in tumor imaging, infections and benign pathologies like ...

We report a case of giant cell tumor occurring in a 12-year-old girl. Radiographs revealed a radiolucent lesion in the proximal epi-metaphysis of the right fibula, which was initially diagnosed as an aneurysmal bone cyst. Magnetic resonance imaging showed an expansile intramedullary lesion with focal multiloculated fluid-fluid levels and also solid mass in the proximal metaphysis. The latter so...

The aim of this study is to determine the value of surgical staging for the two histologic types (expansile or infiltrative) of apparent stage I mucinous ovarian carcinoma. We retrospectively analyzed patients treated from 1976 and 2016 for apparent macroscopic stage I ovarian mucinous carcinoma. Extra-ovarian disease and tumors that metastasized to the ovaries were excluded. Two expert patholo...
