“…To exclude metastasis, we evaluated the case with chest x-ray and CT scan. Many authors report that GCT recurrence is high during the initial two years [17-19]. At 24-months of surgery, the patient was free of symptoms; there was no radiological evidence of recurrence or distant metastasis.…”

A 15-year-old girl presented with pain and swelling on the anterior aspect of the right knee for one year. The radiological evaluation with x-rays and magnetic resonance imaging suggested a benign aggressive lesion of the right patella with a cortical breach. Core needle biopsy of the lesion revealed it to be a giant cell tumor (GCT). She was treated with total patellectomy and end-to-end repair of quadriceps to the patellar tendon. The histopathological report of the whole specimen revealed it to be a GCT with secondary aneurysmal bone cyst (ABC). After 24 months, she was asymptomatic, and there was no evidence of local recurrence or distal metastasis. An extensive review of the literature revealed only four cases of combined GCT with secondary ABC in the patella. Though rare, GCT with secondary ABC of the patella should be kept as a differential diagnosis for anterior knee pain and swelling in young patients. The diagnosis is solely based on histopathological findings. It is imperative to obtain a precise tissue diagnosis in the preoperative period to plan appropriate treatment.

“…GCT lesions are locally aggressive with high chances of recurrence rate. It has been reported that the incidence of metastasis is up to 1%-2% [17-19]. To exclude metastasis, we evaluated the case with chest x-ray and CT scan.…”

“…The patella is an unusual location for any primary or secondary bone tumor, and a neoplasm would rarely be considered in the etiology of anterior knee pain. Therefore, the diagnosis of a tumor within this location is delayed in most patients [ 3 ]. Benign lesions are more common and represent 70% of the tumors affecting the patella.…”

Primary neoplasms of the patella account for less than 1% of all primary bone tumors of the lower extremity, the most frequent of them being the giant cell tumor of bone, the chondroblastoma, and the aneurysmal bone cyst. Herein, we report the case of a 29-year-old woman with an active giant cell tumor of the patella (GCTP) with its clinical and radiological features and a brief review of the literature.

“…Giant cell tumour of patella shows a well-defined, lytic lesion with no periosteal reaction. 5 On magnetic resonance imaging (MRI), Giant cell tumour of patella shows higher signal intensity on T1-weighted sequences, heterogeneous signal intensity on T2-weighted sequences and fatsuppressed T1-weighted sequences shows a heterogeneously signal intensity lesion. 5 Chondroblastoma of patella shows a well-defined, round or oval lytic lesion and periosteal reaction is absent.…”

Introduction: Patella is a very uncommon site for primary bone tumours and fibrous dysplasia lesion in patella has never been reported. Fibrous dysplasia is a benign fibrosseous lesion of the bone where the fibrous connective tissue replaces the normal bone. Case report: We report a case of 23 years female with 7 years history of progressive swelling and anterior knee pain. Radiographs showed enlarged, deformed patella like a shape of banana. The patient underwent patellectomy with extensor mechanism repair and biopsy proved to be fibrous dysplasia. Conclusion: Fibrous dysplasia involving patella is very rare and never been reported earlier. Although primary patellar neoplasm are not common but should be kept in mind in chronic anterior knee pain with swelling for early diagnosis and intervention with intralesional therapy otherwise patellectomy has to be done in more advanced, deformed and enlarged lesions.
