Findings on histologic examination following biopsy vary; findings can range from a well-differentiated chondroma
or low-grade chondrosarcoma to the anaplastic features of a high-grade chondrosarcoma (figure 2).
Radiographic differential diagnoses include chondroma
, osteoblastoma, osteochondroma, meningioma, and fibro-osseous lesions.
Only two prior cases of chondroma
of the urinary bladder wall have been reported.
The closest differential diagnosis on imaging for a convexity or falx chondroma
However, it is difficult to distinguish a chondrosarcoma from a benign chondroma
on imaging, although a CT that shows coarse or stippled calcifications may raise the suspicion of a chondrosarcoma.
2) We report a patient in whom a chondroma
affected the subcutaneous Achilles tendon bursa.
In recent years, many radiologists and clinicians have been working on the development of IFP into metaplasia and chondroma
due to these mesenchymal cells.
Pathology confirmed that it was a benign chondroma
The triad includes benign pulmonary chondroma
(commonly calcified), gastrointestinal stromal tumor, and extra-adrenal paraganglioma.
Carney triad comprises gastric GIST, paraganglioma, and pulmonary chondroma
Tracheal resection and anastomosis for an intratracheal chondroma
in a ball python.
Differential diagnosis for lesions that centered within the thyroid or crycoid cartilage includes giant cell reparative granuloma, brown tumor of hyperparathyroidism, osteoblastoma, chondroblastoma, chondrosarcoma, chondroma
, aneurysmal bone cyst, nonossifying fibroma, foreign body reaction, benign fibrous histiocytoma, malignant fibrous histiocytoma, osteosarcoma with abundant giant cells, and carcinoma (including spindle cell or sarcomatoid carcinoma) with giant cells.
Carney triad usually occurs in young women who present with a combination of gastric GIST, paraganglioma, and pulmonary chondroma
The differential diagnosis of a cholesterol granuloma includes cholesteatoma, mucocele, chondroma
, chondrosarcoma, metastatic carcinoma, dermoid, giant-cell tumor, and cavernous hemangioma.
Likewise, an acellular PA may closely resemble a soft tissue chondroma
or even myxoma.
