Renal Clear Cell Carcinoma Masquerading As Brain Arteriovenous Malformation: A Case Report and Review of the Literature.

Cerebral arteriovenous malformations (AVMs) are tangles of abnormal vessels with early arteriovenous (AV) shunting that can lead to intracerebral hemorrhage, seizures, neurologic deficit, or headache. To date, only a few cases of carcinomas metastasizing to pre-existing cerebral AVMs have been reported in the literature. However, renal clear cell carcinoma (RCC) brain metastases that exhibit early AV shunting, where AVM pathology is not present, are extremely rare.

Utility of cell block preparation in diagnosis of paediatric abdominal neoplasms.

Background: Paediatric abdominal neoplasms are fairly common. Fine needle aspiration cytology (FNAC) is used for the initial evaluation of paediatric abdominal neoplasms. However, sometimes FNA interpretation can be difficult on limited material, owing to tumour heterogeneity and overlapping features.

Diagnostic utility of cytology smears and cell block in adrenal lesions.

Background: Cytology of the adrenal gland is a less performed technique even in tertiary care centres; yet cytological evaluation is an important diagnostic tool for assessment of adrenal lesions. Our objective was to evaluate the diagnostic utility of FNAC smears and cellblock with immunohistochemistry (IHC) in lesions of the adrenal.

Material And Methods: We had a total of 50 cases over a period of 2 years where both FNAC smears and cellblocks were taken.

Cytological diagnosis of adrenocortical carcinoma: A report of 2 cases in children.

Adrenocortical carcinoma (ACC) is a rare tumour, which sometimes affects pediatric age group. Fine needle aspiration cytology (FNAC) is a rarely performed technique in adrenal cortical tumours. There is sparse literature available describing the cytological findings of ACCs in children.
