UNASSIGNED: @entity1048 is a rare benign hyaline cartilage @entity5 situated on the bone surface. This is the presentation of a unique case of @entity1048 arising in the left distal tibial metaphysis of a 25-year-old female @entity1 with a history of antecedent @entity130 . The physical examination revealed @entity4 and tenderness in the anterolateral aspect of the left distal lower limb. Plain radiographs revealed a discernible soft tissue lesion with peripheral foci of mineralization. Computed tomography scans confirmed the presence of a surface-based mass with peripheral ossification and a thin rim of @entity730 . On magnetic resonance imaging, the well-circumscribed mass exhibited intermediate signal intensity on T1-weighted sequences and high signal intensity with foci of decreased signal intensity on T2-weighted sequences. Contrast-enhanced T1-weighted sequences revealed predominantly peripheral enhancement without intramedullary involvement. Following an open biopsy, marginal excision with curettage of the underlying bone cortex was performed. Histologically, the @entity5 consisted of mature hyaline cartilage arranged in distinct lobules. Foci of ossification with mature bone trabeculae forming a thin shell-like structure were identified in the periphery of the @entity5 . The mindbomb E3 ubiquitin protein ligase 1 labeling index was <1%. Based on these findings, the @entity5 was diagnosed as @entity1048 . There has been no evidence of local recurrence at 4 months following surgery. Despite its rarity, @entity1048 must be considered as a possible diagnosis when confronted with a surface-based, mineralized lesion in the metaphysis of long bones.
