Primary hyperparathyroidism is an endocrinopathy which is characterized with the hypersecretion of parathormone. During the progress of the disease bone loss takes place due to resorption on the subperiosteal and endosteal surfaces. Brown tumor is a localized form of osteitis fibrosa cystica, being part of the hyperparathyroid bone disease. It is rarely the first symptom of hyperparathyroidism. Nowadays, the diagnosis is made at an asymptomatic or minimally symptomatic stage. We present a male patient presented with a massive painless swelling in the left maxilla as the first manifestation of primary hyperparathyroidism due to a parathyroid adenoma. Parathyroidectomy was performed, and there was a regression of the bone lesion, without the need of performing other local surgical procedures.

Abstract Brown tumor (BT) is the pathological expression of osteitis fibrosa cystica owing to primary and secondary hyperparathyroidism (HPT). It is a rare benign lesion of skeletal system that usually affects the facial bones, clavicles, ribs, pelvis and extremities. The purpose of this case report is to present the clinical, pathological and radiological findings of BT, rarely seen in adults, originating from the giant parathyroid adenoma and emerging as the first clinical sign of HPT. The patient underwent a successful parathyroidectomy operation and on the first postoperative day, the patient was discharged without any complications. Continuous...

Background: Brown tumor (Osteoclastoma) is a rare benign, focal, lytic bone lesion most commonly attributed to a parathyroid adenoma; it occurs in approximately 5% of patients with primary hyperparathyroidism, and 13% of patients with secondary hyperparathyroidism. Most tumors are located in the mandible, pelvis, ribs, and large bones; only rarely is it found in the axial spine. Case Description: A 37-year-old male with primary hyperparathyroidism presented with an MR-documented T4 and T5 brown tumor (Osteitis Fibrosa Cystica) resulting in an acute paraparesis. The patient successfully underwent excisional biopsy of an expansile, enhancing, bony destructive lesion at the T4-5 level. Subsequently, he required subtotal excision of a left upper parathyroid tumor. Conclusion: Patient with primary hyperparathyroidism may acutely present with paraparesis attributed to brown tumors of the spine warranting emergent operative decompression.

Osteitis Fibrosa Cystica (OFC) is defined as the classic skeletal manifestation of advanced primary hyperparathyroidism. With the increased detection by means of routine calcium screening, the clinical profile of primary hyperparathyroidism in Western countries has shifted from symptomatic disease to one with subtle or no specific symptoms (“asymptomatic” primary hyperparathyroidism). The authors describe a classical feature of advanced primary hyperparathyroidism due to a parathyroid adenoma and its successful treatment.

Abstract Introduction: Osteitis fibrosa cystica (OFC) is the most serious bone involvement of primary hyperparathyroidism (PHPT), it is characterized by subperiosteal resorption, lytic lesions and the appearance of brown tumors; this is why, in some cases, this condition can easily be mistaken for a malignant neoplasm. Its prevalence in developed countries is only 5%. Clinical Case: We present a 58-year-old woman, with no relevant personal history, who came to the emergency room with pain in her right shoulder after an accidental fall on the bus. The humerus radiograph shows a pathological fracture of the right humerus, with significant osteopenia. In the emergency analysis, serum Calcium 13.3 mg / d), Ionic Calcium 7.03 mg / dL, Phosphorus 2.4 mg / dL, Alkaline Phosphatase 248 U / L and normal kidney function stand out. With a diagnosis of severe hypercalcemia, treatment was started in the emergency room with serum therapy (1000 ml of 0.9% physiological saline in 4 hours) and intravenous diuretic treatment (furosemide 40mg) with a decrease in calcemia to 12.8mg / dL. Later, she was admitted to the Internal Medicine hospital ward to perform a differential diagnosis of hypercalcemia secondary to a primary tumor, Multiple Myeloma or Primary Hyperparathyroidism. The study findings are: Calcium metabolism: PTH 660 pg / ml (12 - 65), 25 Hydroxyvitamin D: 14.00. Thyroid ultrasound: Posterocaudal to right thyroid lobe, an area of ​​echogenicity slightly lower than the thyroid is identified, of dimensions not estimated by endothoracic component, which could correspond to a parathyroid adenoma. Body CT: Neck: Heterogeneous nodule dependent on the posterior region of the right thyroid nodule with endothoracic extension. Skeleton: Lytic lesions with a tumor aspect in the humerus, right scapula and bilateral seventh rib and right pubic branch. Skull: Diffuse increase in bone density of the calvaria, showing multiple punctate lytic lesions with a permeative appearance. Bone densitometry: Femur neck: - <1.5, Lumbar spine: - <3.0 With the diagnosis of PHPT causing osteitis fibrosa cystica, surgical intervention was decided. Under general anesthesia, a selective right approach was performed, finding a large parathyroid adenoma weighing 17 grams. PTH fell to 36 pg / ml after surgery. At 9 months after surgery, the patient presented calcium levels of 9 mg / dl and PTH 146 pg / ml with clear radiological improvement. Discussion: Osteitis fibrosa cystica is rare in our environment, it is often confused with other neoplasms. After parathyroidectomy, patients with PHPT have a marked and sustained recovery from OFC, although in some cases this recovery can only be achieved after several years. We consider this case of interest, since it illustrates the importance of evaluating the study of phospho-calcium metabolism and parathyroid function in all patients with bone lesions to rule out Primary Hyperparathyroidism with OFC.

Abstract Zoledronic acid is a very effective (IV) amino bisphosphonate which is indicated in osteoporosis, hypercalcemia of malignancy, multiple myeloma, Paget’s disease, and bone metastases from solid tumors. Bisphosphonate inhibits bone resorption through actions on osteoclast activity resulting in increasing bone density. Unfortunately, there are side effects associated with zoledronic acid one of those is mild to moderate hypocalcemia. Hungry Bone Syndrome (HBS) is defined as a severe drop in calcium levels less than 2.1 mmol/L and/or prolonged hypocalcemia for more than 4 days post parathyroidectomy. Most seen in patients’ who have secondary hyperparathyroidism compared to primary hyperparathyroidism. The sudden drop of parathyroid (PTH) levels post parathyroid resection after a prolonged duration of high PTH levels causes net calcium to move into the bone, this is the most proposed hypothesis. The authors report a case of a 32 years old female known case of severe osteoporosis presented to the emergency department complaining of left hip pain after a short height fall admitted as a case of pathological fracture. Furthermore, upon admission was vitally stable although on examination the patient had left side hip pain and tenderness otherwise unremarkable. Initial lab investigation showed a calcium level of 2.57 mmol/L and PTH level 37 pmol/L otherwise electrolytes and full blood count were unremarkable. Radiological investigations were done, and an X-ray has shown a left hip fracture where the patient underwent an operating room for fixation. In addition, a 99mTc-HDP bone scan revealed hyperparathyroidism and brown tumor. 99m Tc SESTA-MIBI whole body scan suggested metabolic bone disease. Furthermore, the parathyroid showed suggested typical parathyroid adenoma below and lateral to the lower pole of the left thyroid lobe. The ultrasound of the thyroid showing a well-defined hypoechoic nodule 2.5x1.15 cm with significant hypervascularity is seen, which is most likely to be enlarged left parathyroid gland. Thus, diagnosis of primary hyperparathyroidism has been reached with parathyroid adenoma which was resected during a hospital stay. The patient received pre-op zoledronic acid as a treatment for osteoporosis prior to the hip operation. After the parathyroid adenoma resection, the patient had a sudden drop of PTH and developed hypocalcemia which was 1.1 mmol/L. Thus, the complication of post operated parathyroid adenoma of HBS diagnosis has been made. Interestingly the patient needed to increase the length of stay of the hospital due to refractory hypocalcemia where the patient has been receiving IV calcium and vitamin D supplementation which hadn’t improved until a month of IV calcium gluconate. Although, the patient didn’t develop any signs or symptoms of hypocalcemia.

Abstract Background: Brown tumors are a part of the complex “osteitis fibrosa cystica” which is a diffuse resorptive process of the bone resulting from uncontrolled hyperparathyroidism. Although these brown tumors were fairly common in the past1, the incidence of brown tumors is now extremely rare in the United States due to early diagnosis and treatment of hyperparathyroidism. Here we describe an unusual presentation for osteitis fibrosa cystica. Clinical Case: A 38 year old woman was admitted to the hospital with rapidly growing facial swelling in June 2019. The swelling initially appeared in January 2019 and had rapidly increased in size since April 2019. The mass was malodorous, painful and interfered with oral intake. The patient smoked 1 pack per day for 13 years. A CT scan of the head and neck with contrast showed a 3.6 x 4.5 x 3.3 cm mass destroying the right mandibular body, involving the right platysma muscle and displacing the central and lateral incisor teeth and was concerning for malignancy. The initial impression was that this was likely a squamous cell carcinoma with local and perhaps distant metastases, complicated by humoral hypercalcemia of malignancy and she was admitted for management. Upon admission, her calcium level was 14 mg/dL, albumin 4.1 g/dL, phosphorus 1.4 mg/dL PTH level was 890 pg/mL and vitamin D level was 22 ng/mL. Since the high PTH did not fit with hypercalcemia of malignancy, further evaluation was undertaken. A thyroid ultrasound showed a 4.6 x 1.8 x 1.5 cm isoechoic, heterogeneous lesion in the left lower pole, and Tc-99 sestamibi scan suggested parathyroid origin. The biopsy of the mouth lesion showed fibro histiocytic proliferation with multiple giant cells, negative for malignancy and consistent with a brown tumor. CT scan of the chest, abdomen and pelvis did not reveal any other masses or lytic lesions. . A skeletal survey showed another 2 cm lytic lesion in the proximal left humeral metaphysis which was not biopsied. On parathyroidectomy, the patient was found to have an enlarged left inferior parathyroid gland measuring 3.3 x 3.0 x 0.8 cm weighing 7.093 grams. Intraoperatively PTH level decreased from 890 pg/mL to 69 pg/mL. Her calcium levels returned to normal post-operatively and she was discharged home. Pathologic examination report revealed the mass to be a parathyroid adenoma. The patient reports a reduction in the size of her mandible mass since the surgery. Conclusion: Although uncommon, brown tumors can be seen in uncontrolled primary hyperparathyroidism. The mandible is a common site, though, as in this case, it is less common for it to be the only site affected Reference: 1. Rosenberg, E. H. (1962). Hyperparathyroidism.

Brown tumor is a benign bone lesion that arises as a direct result of parathyroid hormone on bony tissue in some patients with hyperparathyroidism. Multiple brown tumors may simulate malignant disease and it is a real challenge for the clinicians in the differential diagnoses. Brown tumor as the only and initial symptom of normocalcemic primary hyperparathyroidism is a rare clinical entity. Here, we present a case with multiple brown tumors in a young normocalcemic woman as a sequele of primary hyperparathyroidism mimicking bone metastases. Bangladesh J.

ABSTRACT Introduction To report two unusual cases of primary hyperparathyroidism (HPT) that initially manifested with a “ jaw tumor” and to discuss the clinical implications of a giant cell granuloma vs an ossifying fibroma of the jaw. Material and methods The history, physical examination, laboratory values and the imaging and pathologic findings are described in two patients who presented with a “jaw tumor” and were subsequently diagnosed with primary HPT. The diagnosis and management of osteitis fibrosa cystica and HPT-jaw tumor syndrome are reviewed. Results Patient #1 was a 70-year-old male who presented with hypercalcemia, severe jaw pain, and an enlarging mass in his mandible. Biopsy of the mass revealed a giant cell tumor and he was subsequently diagnosed with primary HPT. A sestamibi scan demonstrated a single focus of abnormal radiotracer accumulation, corresponding to a 13,470 mg parathyroid adenoma, which was resected. Postoperatively, the serum calcium normalized and the giant cell granuloma regressed spontaneously. Patient #2 was a 36-year-old male with four incidentally discovered tumors of the mandible and maxilla, who was diagnosed with normocalcemic HPT and vitamin D deficiency. Biopsy of one of the tumors revealed an ossifying fibroma. Bilateral neck exploration revealed a 2480 mg right inferior parathyroid adenoma, which was resected. Postoperative genetic testing revealed an HRPT2 gene mutation. He subsequently underwent resection of an enlarging ossifying fibroma of the mandible with secondary reconstruction. Conclusions A “jaw tumor” in a patient with primary HPT may be a manifestation of osteitis fibrosa cystica or HPT-jaw tumor syndrome underscoring the importance of biopsy and genetic testing for management and follow-up.
