Benign chondroblastoma with recurrent soft-tissue and intra-articular lesions. This, compounded with nonconforming radiological features, leads to the tragic delay in diagnosis.

She also gave history of trauma at the same site. Their anatomic and theoretical basis with an emphasis on chondrolastoma, pathology and clinical biology. Benign and malignant cartilage tumors of bone and joint: Click here for information on linking to our website or using our content or images.

A fine- needle aspiration diagnosis. The giant cells were indistinguishable from those seen in other bone neoplasms [ [Figure – 2] a and c]. Calcification, chondroblastoma, fine needle aspiration cytology FNACgiant cells. The extra-osseous component was large and measured 7. Cytologic features of primary chondroid tumors chlndroblastoma bone in crush preparations.

Fine needle aspiration cytology of chondroblastoma of the fibula

Fine needle aspiration cytology of chondromyxoid fibroma: Histopathology confirmed the diagnosis of chondroblastoma. Cytologically histiocytes of LCH are like chondroblasts of chondroblastoma but not associated with any type of matrix production. A Reinterpretation of the so-called calcifying or chondromatous giant cell tumor. Chondroblastoma of the mandibular condyle: With reference to the histogenesis of chondroblastoma, chondromyxoid chodroblastoma and mesenchymal chondrosarcoma.


Magnetic resonance imaging knee joint short tau inversion recovery Coronal reveals abnormal hyperintense medullary marrow signal in the head of fibula epiphysis extending inferiorly into upper shaft of the fibula.

Though the age of the patient and location of the lesion in the given bone are key pieces of information, accurate and early diagnosis is a must for planning appropriate treatment.

Areas of cartilage formation and chicken wire calcification were noted [ Figure 1d ]. No mitotic figures were seen. The histological diagnosis of typical chondroblastoma is not difficult due to their characteristic appearance with rounded or polygonal chondroblasts, multinucleated giant cells and eosinophilic chondroid extracellular matrix with focal chicken-wire calcification. A cytoloyy of seventy cases. Tumors of bone and cartilage. Spindle to stellate cells, scattered singly and in clusters were also noted.

It is necessary to differentiate chondroblastoma from other giant cell-rich lesions, as chondroblastoma exhibits predominantly benign behavior, though recurrences and metastasis are on record. Schajowicz F, Gallardo H. Cytology smears in both the cases showed similar findings. Fine needle aspiration cytology in the diagnosis of bone chondroblwstoma. In eight cases, diagnosis was rendered preoperatively. Surg Gynecol Obstet ; Recognition of chondroblasts based on its cytological features has been chonfroblastoma as the diagnostic hallmark of this lesion along with chondroid matrix surrounding the individual cells.


Due to the difference in the treatment protocol and prognosis, preoperative diagnosis is mandatory. Related articles Chondroblastoma chondroblasts osteoclast-like giant cells temporomandibular.

Clinical diagnosis was giant cell tumor of bone. Schajowicz F, Gallardo H.

An open biopsy followed by curettage and bone grafting was performed. In correlation with the radiological findings, a provisional diagnosis suggestive of chondroblastoma was offered.

How to cite this article: Here, we report cytomorphology in two cases of chondroblastoma confirmed by histopathology with a brief review of literature. Giant cell tumor of bone. Magnetic resonance imaging of leg showed abnormal marrow infiltration in medullary cavity of head and upper shaft of fibula hypo-intense on T1-weighted T2-weighted sequences and hypo-to hyper-intense on short tau inversion recovery STIR sequence, the vertical length being 8 cm approximately.

High failure rate of aspiration cytology in bone tumors is mainly due to the hardness and fibrous nature of the tumors and if they are guarded by thick cortex leading to difficulty in piercing the needle. FNAC of giant cell tumor also shows two population of cells; dominant histiocytoid mononuclear cells and multinucleated giant cells.
