Chondroblastic Osteosarcoma

This is the fourteenth case of an intracranial and dural-based osteosarcoma in the literature to date. The case involves a forty-year old woman with a previous history of a brain tumour, which was treated with surgery, chemotherapy and radiotherapy six years previously. The hypothesis is that this rare malignancy is secondary to the radiation exposure given the growth of the lesion in the previous radiation field

Neuroendocrine Carcinomas

Introduction. Small cell neuroendocrine carcinomas of the urinary tract is an extremely rare entity and very few cases have been reported in the literature. Small cell neuroendocrine carcinoma of the urinary tract (SCC-UT) is the association between bladder and urinary upper tract-small cell carcinoma (UUT-SCC). It characterized by an aggressive clinical course. The prognosis is poor due to local or distant metastases, and usually the muscle of the bladder is invaded.Case Presentation. We report a rare case of a 54-year-old Arab male native of moroccan; he is a smoker and was referred to our institution for intermittent hematuria. Following a diagnosis of small cell neuroendocrine carcinomas of the ureter and the bladder, thoracoabdominal-pelvic CT was done, and the staging of the tumor was done in the bladder (T2N0M0) and (T1N0M0) in the ureter. Neoadjuvant alternating doublet chemotherapy with ifosfamide/doxorubicin and etoposide/cisplatin was realized, and nephroureterectomy associated to a cystoprostatectomy was carried out. After 24 months of followup, no local or distant metastasis was detected.Conclusion. The purpose of this review is to present a rare case of pure small cell neuroendocrine carcinoma of the urinary tract and review the literature about the place of neoadjuvant chemotherapy in this rare tumors.

Infantile Fibrosarcoma

Infantile fibrosarcoma is a rare type of soft tissue sarcoma seen in children usually less than 2years of age. Few cases of giant infantile fibrosarcoma have been reported in literature. We report a rare case of a giant multi-nodular infantile fibrosarcoma in the left anterolateral chest wall in a 7-year-old boy. The tumour was said to have been recurrent twice for about 6 years. At presentation patient was evaluated and was commenced on 6 cycles of neoadjuvant chemotherapy with vincristine, adriamycin and cyclophosphamide (VAC) regimen to alternate with Ifosfamide/Etoposide (IE) regimen with very good response. Thereafter, had a wide local excision of the tumour and then had 4 more cycles of adjuvant chemotherapy. His 6months follow up showed no evidence of tumour recurrence. Infantile fibrosarcoma is said to be chemo-sensitive tumour with very good response, though surgical excision is the main treatment of choice and overall it is said to have a good prognosis.

AbstractPrimary osteosarcomas of the skull and skull base are rare and comprise < 2% of all skull tumors. In head and neck osteosarcomas, the chondroblastic subtype occurs most frequently, which has an exceedingly poor outcome, but its image characteristic remains unknown. Herein, we report a case in the right occipital bone of the skull base and the unique characteristics of image. Pathologic examination of the surgical specimens led to the diagnosis of chondroblastic osteosarcomas. We believe those image characteristics can improve the understanding of skull chondroblastic osteosarcoma and the preoperative diagnosis.
