Postembolization infarction in juvenile nasopharyngeal angiofibroma.

We report the occurrence of cerebro-vascular accident, following selective embolization of internal maxillary artery (IMA) in a young male patient aged 18 years admitted at ENT Department, Abbasi Shaheed Hospital (ASH) with diagnosis of recurrent juvenile nasophayrngeal angiofibroma (JNA). Angiography and selective trans-femoral embolization was done as an adjunctive measure before the definite surgical removal of this benign tumourous condition. The child developed weakness of the right half of body with slurred speech and drowsiness. CT scan of brain revealed the diagnosis of postembolization infarction. The patient recovered with no obvious signs of clinical residual weakness. Surgical excision after ligation of feeding vessel has been planned.

Follicular dendritic cell sarcoma of tonsil.

Follicular dendritic cell sarcoma is a very rare entity. So far only 12 cases have been reported world wide with involvement of tonsil. We present a new case of follicular dendritic cell sarcoma of the tonsil in a 52 years old woman with no evidence of neck node involvement. She had undergone diagnostic tonsillectomy due to unilateral tonsillar enlargement. The final diagnosis after histological review and immunohistochemical stains was follicular dendritic cell sarcoma. Bone scan showed no metastasis. One year follow-up after postoperative chemotherapy showed no evidence of local or regional recurrence. Follicular dendritic cell sarcoma is a rare and underdiagnosed neoplasm. It should be included in the differential diagnosis of any tonsillar mass in adults. Follicular dendritic cell markers such as SR-100, CD21 and/or CD35 are essential for the diagnosis.
