Chondroblastoma of the Occipital Bone With Atypical Genetic Markers: A Case Report.

Cureus 2022 Feb 21;14(2):e22451. Epub 2022 Feb 21.

Department of Neurological Surgery, University of Washington, Seattle, USA.

Chondroblastoma is a rare bone tumor, most often found in epiphyseal plates of long bones. It has infrequently been reported in the skull, most often in the temporal bone. We present a case of chondroblastoma of the occipital bone in a pediatric patient presenting with a bony protuberance of the occiput and imaging consistent with obstructive hydrocephalus, which persisted even after removal of the obstructing tumor.

Ali H AlYami

Cureus 2021 Nov 11;13(11):e19467. Epub 2021 Nov 11.

Department of Surgery, Ministry of the National Guard - Health Affairs, Jeddah, SAU.

We present a case of chondroblastoma-like chondroma (CLC) of soft tissue that manifested as a palmar mass on the left hand of an 84-year-old man. Physical examination, imaging investigation, and needle biopsy initially suggested a giant cell tumor of the tendon sheath, until a correct diagnosis was made based on excised specimen histology. The patient underwent a marginal excision for soft-tissue mass removal. Read More

A Case of Arthroscopic Treatment of Chondroblastoma-Induced Chondropathy Situated at the Posterior Talus.

J Am Podiatr Med Assoc 2021 Sep;111(5)

Chondroblastoma located in the talus is a rare incidence, and due to the weightbearing duty of the talus, the results of local excision may not be favorable. While the volume of the tumor increases, more sophisticated techniques may be undertaken. Cell-free matrix application for extensive osteochondral defects is gaining popularity for its structural support when it is used with microfracture and autograft application. Read More

Tumors and pseudotumors of foot and ankle: Bone lesions.

Foot (Edinb) 2021 Dec 29;49:101845. Epub 2021 Jun 29.

Radiology & Orthopeadic Surgery, UT Southwestern, 5323 Harry Hines Blvd, Dallas, TX, United States. Electronic address:

Bone tumors and tumor-like lesions (pseudotumors) are not uncommonly encountered as asymptomatic findings on imaging, or as symptomatic lesions clinically. Radiographic imaging is the first diagnostic tool for their management strategy, since the symptoms are commonly non-specific, such as pain, swelling, and redness. Image findings must be analyzed with attention to the specific features such as lesion location, margination, zone of transition, mineralization, size and multifocality, soft tissue component and/or loco-regional extent.
