Abstract

Hyperparathyroidism causes disturbance in the mineral and bone assimilation process which might produce skeletal as well as extra skeletal changes. Renal insufficiency disorders might disturb the homeostasis of calcium, vitamin D and bone metabolism causing secondary hyperparathyroidism. A complication of hyperparathyroidism is Browns tumour, which is a result of disorganised osteoclast activities. It is a type of osteitis fibrosa cystica caused due to the excess osteoclast activity during hyperparathyroidism.  It can be located in any part of the body but rarely is it seen in the craniofacial area. Here also it commonly affects the mandible than the maxilla. Here is such a rare case of Browns tumour in the paranasal region in a 15-year-old boy with stunted growth. His renal parameters were deranged raising a suspicion for renal insufficiency causing secondary hyperparathyroidism, which could have been the cause for his stunted growth too. The aim to present this case is to create awareness amongst the clinicians while treating cases of stunted growth or paranasal cystic swellings, to rule out any renal disease or hyperparathyroidism. As in such instances early management might minimise the chances of surgery and reducing the mortality rate.
