This is a rare case of osteoblastoma in shaft of a long bone, in an unusual location, causing a therapeutic dilemma. Aims & Objectives: Osteoblastoma and osteoid osteoma are closely related lesions with similar histological patterns and indistinguishable radiographic features. This case was studied to understand the similarities and differentiating features of the two. Methods: Here was a case of 18 years old male patient with history of bony swelling and pain in his right leg which relived with a dose of Aspirin. After thorough examination plain radiographs and CT scan of the part was done. Surgical excision of the lesion was done and sent for histopathology examination. Patient was adequately treated and followed up at 1,3,12 & 18 months post operatively to assess the involved site and evidence of recurrence. Result: Plain radiographs and CT scan of the part involved provisionally diagnosed the lesion as osteoid osteoma. Histopathology examination found features suggestive of osteoid osteoma and a diagnosis of osteoblastoma was given, considering the size of the nidus. Patient was followed up at 1,3,12 & 18 months post operatively and there was no evidence of recurrence. Conclusion: Osteoblastoma and osteoid osteoma were classified as variants of single tumour type based on a number of shared histological and radiographic features. Most significant difference between the two lesions is the size of the nidus. Thus, there may be transitional zone of uncertainty in establishing the correct diagnosis. Osteoid osteoma must be considered a differential diagnosis when the lesions are large and in unusual sites like long bones.

The location of giant cell tumors in areas like distal femur, proximal tibia, etc. makes the management of the tumor challenging. Inadequate curettage may lead to recurrence of the tumor, which has to be kept in mind even before planning for surgery. Aims and Objectives: Large giant cell tumor management has always been difficult. Even more difficult is tackling the complication like recurrence. This case was studied to know how the extended curettage with phenol crystal helps in reducing the risk of recurrence of GCT. Methods: An 18 year old male clinically and radiologically diagnosed to have GCT in the medial condyle right distal femur was taken up for extended curettage with phenol crystal wash, bone grafting and cementation with allograft mixed with bone cement and medial condylar plating for right distal femur. Followed by a histo-pathological examination of the curetted sample. Regular follow-up of the patient was done at 1, 3, 6, 12 and 18 months post operatively to assess for recurrence of the tumor. Result: Histo-pathologically the diagnosis of giant cell tumor was confirmed. At regular follow-ups of 1, 3, 6, 12 and 18 months post operatively and also an MRI done at 12 months follow-up period showed no evidence of recurrence of the tumor. Conclusion: Giant cell tumor management has better outcomes with extended curettage with phenol crystal wash followed by bone grafting, cementing and plating. This study has shown no evidence of recurrence with the following technique at 18 months follow-up period. Phenol crystals can be used as a better alternative to liquid nitrogen for extended curettage.

Materials and Methods: A 22 years old male presented with complaints of left hip pain since 20 days, was examined clinically and radiologically. On MRI, he was diagnosed to have a non-expansile lytic lesion in the left proximal femur with features suggestive of aneurysmal bone cyst or an unicameral bone cyst. Patient was planned and taken up for aspiration and curettage followed by a single sitting sclerosant therapy with 3% polidocanol, bone cementing combined with plating. Curetted sample was sent for histo-pathological examination. Patient was advised restricted weight bearing for a period of 4 weeks. Regular follow-ups of the patient was done at 1, 3, 12 and 18 months post-operatively to assess for recurrence. Results: Histo-pathological examination confirmed the diagnosis of aneurysmal bone cyst. With regular follow-ups,...
