Parathyroid adenoma is the most common cause of primary hyperparathyroidism. It commonly occurs in adults in the age group of 5th to 6th decade but it is rare in children. We present the case of a 12 year old female child presenting with renal calculi. Fine needle aspiration cytology (FNAC) revealed the diagnosis of Parathyroid adenoma which was further confirmed on histopathology with radiological and biochemical correlation. Awareness of parathyroid adenoma and its cytological features is important in order to differentiate it from thyroid lesions.
