Breast neoplasms containing bone and cartilage

Virchows Archiv A Pathological Anatomy and Histopathology, 1983
A total of 307 breast neoplasms and tumour-like conditions were reviewed to assess the frequency with which bone and/or cartilage occurred. Of 90 fibroadenomas, 1 (1.1%) and 2 of 158 breast carcinomas (1.3%) contained bone, one benign mesenchymoma contained cartilage, and one benign "mixed" tumour (pleomorphic adenoma) displayed cartilage and bone ...

Reactive bone lesions mimicking neoplasms

Seminars in Diagnostic Pathology, 2011
Reactive lesions of bone and soft tissue can appear alarming on histologic examination because they are often cellular and have atypical (activated) cytologic features, such as distinct nucleoli and mild hyperchromasia, and mitotic activity. Reactive lesions of bone and periosteum also produce bone and cartilage matrix, resulting in confusion with ...

Pathology of pleomorphic/undifferentiated and dedifferentiated bone neoplasms

Seminars in Diagnostic Pathology, 2021
Primary malignant bone tumors are uncommon and their accurate classification requires careful correlation of clinical, radiological, and pathologic findings. It is a heterogeneous group of tumors with a wide spectrum of morphology and their biological potential can be of low- or high-grade, depending on their risk for developing metastases.

Primary bone neoplasms in beagle dogs exposed by inhalation to aerosols of plutonium-238 dioxide.

Journal of the National Cancer Institute, 1981
Primary bone neoplasms developed in beagle dogs briefly exposed by inhalation to aerosols of 238PuO2. 238PuO2 was initially deposited in the respiratory tract where it was retained with a half time greater than 100 days.

Temporal bone neoplasms: a report on 20 surgically treated cases.

Journal of Neurosurgery, 1992
The surgical resection of neoplasms involving the petrous bone and surrounding areas in 20 patients is reported. Technical advances described include the total resection of several tumors previously considered inoperable due to involvement of dura and ...

Aspiration biopsy of primary neoplasms of bone.

The Journal of Bone & Joint Surgery, 1989
Aspiration biopsy of bone is a simple and relatively safe diagnostic tool that had a diagnostic accuracy of 72 per cent in thirty-one patients who had a primary bone tumor that was suspected of being malignant and of 83 per cent in twelve patients who had a suspected giant-cell tumor. However, twenty-six primary lesions of bone that were thought likely

Comparison of bone scans and radiography for detecting bone neoplasms in dogs exposed to 238PuO2.

American Journal of Veterinary Research, 1980
Radioisotopic bone scans and radiography were used to detect bone neoplasms in 144 dogs that inhaled alpha-particle-emitting 238PuO2 particles. Radiography was used routinely to survey the skeleton of the dogs.

Extradural Petrous Bone and Petroclival Neoplasms

1991
Extradural petroclival tumours are composed of a spectrum of histological and anatomical configurations dictating a variety of surgical approaches. The experience with 68 such tumours operated at the University of Pittsburgh is presented, emphasizing the basal subfrontal and lateral approaches. 85% of these tumours are benign or low-grade malignancies,

[The role of projectional radiography in the detection of primary malignant and indeterminate bone neoplasms].

RöFo. Fortschritte auf dem Gebiet der Röntgenstrahlen und der bildgebenden Verfahren (Print), 2005
PURPOSE To evaluate the role of projectional radiography in the detection of primary and potentially malignant bone neoplasms. MATERIALS AND METHODS We retrospectively reviewed the images and medical records of 80 patients (42 male, 38 female; range: 6

Soft Tissue and Bone Neoplasms

2018
Bone and soft tissue tumors are overall rare but are histologically complex and biologically diverse. Recurring molecular events help define benign and malignant entities as well as confirm the neoplastic nature of lesions previously considered to represent reactive proliferations.
