Introduction: Fibrocartilaginous dysplasia (FCD) is a variant of fibrous dysplasia (FD) with extensive cartilaginous differentiation. This has been reported in both monostotic and polyostotic types of FD, the proximal femur being the most common site involved.
Case Report: We report five cases of fibrocartilaginous dysplasia with varying degrees of cartilaginous differentiation. The age of the patients ranged from 7 to 30 years, and there was a female predominance (M:F ratio of 1:4). The proximal femur was the site of involvement in all the cases. Imaging showed well demarcated radiolucent lesions with stippled calcifications. Histologically, cartilaginous areas were noted juxtaposed to typical areas of fibrous dysplasia. Four of the patients were treated with curettage and one with a marginal resection. None of the five cases had recurrences at the past follow-up.
Conclusion: FCD is a rare variant of fibrous dysplasia which needs to diagnosed and treated early, as there is a high risk of pathological fracture.

Case: A pediatric patient with focal fibrocartilaginous dysplasia (FFCD) developed angular deformity and growth arrest despite standard guided growth management. The patient underwent implant-mediated guided growth for proximal tibia varus deformity which recurred; subsequently, a physeal bar of the medial proximal tibia was diagnosed, which progressed to physeal arrest.
Conclusion: Treatment options for FFCD-associated angular deformity include observation and guided growth.

Article Synopsis
- - A 3-year-old boy was diagnosed with focal fibrocartilaginous dysplasia (FFCD) at the upper left tibia, causing a progressive deformity in his leg.
- - He underwent curettage (surgical scraping) of the lesion and lateral proximal tibia hemiepiphysiodesis using 8 plates to correct the deformity.
- - The treatment was successful; the deformity was corrected within a year, the plates were removed, and the child continues to be monitored until he reaches skeletal maturity.

Article Synopsis
- The study investigates fibrocartilaginous dysplasia (FCD), a subvariant of fibrous dysplasia (FD), focusing on its clinical, pathological, and genetic characteristics.
- It included a cohort of 24 patients, confirming FCD diagnoses through various methods and identifying genetic mutations using Sanger sequencing.
- Findings revealed specific radiographic and histological features, alongside shared mutations in both fibro-osseous and cartilaginous components, confirming FCD as a variant of FD.

Fibrocartilaginous dysplasia (FCD) is a variant of fibrous dysplasia that often involves the proximal femur in young adults. It has a similar appearance on imaging as other entities but has stippled calcifications within the lesion. The differential diagnosis often includes benign and malignant tumors such as fibrous dysplasia, chondroblastoma, enchondroma, and chondrosarcoma.

Focal fibrocartilaginous dysplasia is an uncommon benign bone condition that predominantly affects children and typically leads to varus deformities in the proximal tibia. It was first described by Bell in 1985. The etiology remains unknown and the diagnosis is radiological; biopsy is not necessary.
