Brown tumor represents a serious and late bony complications of advanced hyperparathyroidism with a frequency of 1.5–1.75 percent in secondary hyperparathyroidism and 3–4 percent in primary hyperparathyroidism. [1,2] Here we describe an extremely rare case of a 19-year-old male patient with a brown tumor localised in the maxilla and mandibular due to secondary hyperparathyroidism compromising m...

Ureteritis cystica is an uncommon cause of acute renal pain. The aetiology remains unclear and the diagnosis may be difficult to establish. We report the case of a 29 year old woman with a history of repeated urinary tract infections presenting with acute renal colic in the absence of lithiasis. We review the diagnostic tools available to make the diagnosis and the recent pertinent literature.

We reconsider the problem of gravitational structure formation inside and outside General Relativity (GR), both in the weakly and strongly non-linear regime. We show how these regimes can be explored observationally through clustering of high order cumulants and through the epoch of formation, abundance and clustering of collapse structures, using Press-Schechter formalism and its extensions. W...

We observed a patient with a giant brown tumor of the iliac bone due to hyperparathyroidism. There was a risk of pathologic fracture due to huge cysts produced by bone absorption. In hyperparathyroid crisis, control of severe hypercalcemia is difficult without resection of the parathyroid gland.

Five German shepherd puppies, aged between 66 and 174 days (4 of which had the same parents) had ananastasia with deformation of limbs. Histopathologically, all the puppies showed moderate to marked fibrous osteodystrophy with parathyroid gland activation. These puppies were fed a diet consisting of 80% steamed rice and 20% raw meat. It was implied that though the diet contained the required le...

Brown tumors are focal bone lesions, encountered in patients with uncontrolled hyperparathyroidism. They can be located in any part of the skeleton. Clinically significant lesions in the craniofacial bones are rare. Craniofacial involvement may cause facial disfiguration and compromise social ease of the patient and normal functions, such as chewing, talking, and breathing. In this case report,...

Brown tumor of hyperparathyroidism (BTHPT) is rare in the United States and not frequently seen in clinical practice. This is likely because early diagnosis and prompt treatment of this disease process prevent the progression and development of BTHPT. Conversely, BTHPT is more common in underdeveloped countries where fewer patients have access to health care and hyperparathyroidism (HPT) goes u...

We herein report a rare case of a 66-year-old woman who had synovitis-acne-pustulosis-hyperostosis-osteitis (SAPHO) syndrome with marked sternal osteitis and bilateral pleural effusions. SAPHO syndrome was diagnosed based on the characteristic features of a hyperostotic sternum and thoracic spine. The inflammatory changes of sternal osteitis and involvement of the adjacent soft tissue were assu...
