Abstract:

Brown tumors, also recognized as osteitis fibrosa cystica or osteoclastoma, represent a unique pathological entity intricately linked to hyperparathyroidism. Although benign in nature, brown tumor can manifest as focal bone abnormalities, presenting diagnostic challenges due to their striking resemblance to malignant bone tumors, particularly bone metastases. A 24-year-old woman presented with a lump on her left knee and right lower leg pain. Imaging unveiled multiple osteolytic lesions resembling aggressive bone tumors. Subsequent investigations, including abdominal USG, thyroid USG, bloodwor

Abstract:

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:

Brown tumors are rare focal giant cell lesions of the bone caused by primary hyperparathyroidism (HPT). Brown tumor was reported in 1891; it presents as the end-stage findings of HPT. Common involvements are skull and pelvic girdle. We describe a case of 46-year-old female hemodialysis patient, with secondary HPT in whom multiple masses lesions of the left maxillary sinus and frontal bone were radiologically suspected to be brown tumor. This unusual manifestation of secondary HPT can be expected to occur with increased longevity of patients with renal failure and illustrates the need to includ

Abstract:

Brown tumors are osteolytic bone lesions that occur as a result of persistent hyperparathyroidism. They usually appear late in the natural history of the disease and are currently very rare due to an earlier diagnosis of primary hyperparathyroidism. We present the case of a 53-year-old female with a 2-month history of bitemporal hemianopsia and diplopia. A computed tomography showed an osteolytic bone lesion that involved the sphenoid corpus and clivus. A biopsy was made and the histopathology result was consistent with a brown tumor.

There are various causes of multiple lytic lesions in bone in adults, among which metastases and multiple myeloma top the list. Brown tumor is a rare cause of multiple lytic lesions in bone in the present era. This is due to the early diagnosis of hyperparathyroidism by serological investigations and effective treatment. Brown tumor is named after its gross pathological appearance and is focal reactive osteolysis secondary to elevated parathyroid hormone.

Abstract:

Hyperparathyroidism (HPT) is a condition in which one or more parathyroid glands produce increased levels of parathyroid hormone (PTH), causing disturbances in calcium homeostasis. Most commonly HPT presents with asymptomatic hypercalcemia but the clinical spectrum may include disturbances reflecting the combined effects of increased PTH secretion and hypercalcemia. Brown tumors are rare, benign, tumor-like bone lesions, occurring in 1.5% to 4.5% of patients with HPT, as a complication of an uncontrolled disease pathway, and are nowadays rarely seen in clinical practice.

Hibernoma is a rare benign tumor considered to arise from remnants of fetal brown adipose tissue. It tends to occur in sites where brown fat persists beyond fetal life, such as the interscapular region, but can occur in sites where brown fat is usually absent in adults. Clinically, hibernomas are slow-growing, asymptomatic tumors. However, unlike lipomas, MRI findings sometimes mislead clinicians to diagnose a malignant neoplasm.

Computed tomography (CT) demonstrated an expansile and radioluscent lesion in the left maxillary sinus. Incisional biopsy was performed, and the diagnosis was Brown tumor.

The diagnosis of osteolytic lesions of the jaws can be challenging. Case Reports: Two cases of brown tumor of hyperparathyroidism were reported. A 76- year-old female patient presented with indolent swelling of her right lower jaw measuring approximately 5 cm /6 cm. The panoramic radiograph showed a well-defined osteolytic radiolucency involving the entire mandibular symphysis. Blood investigations revealed High level of parathyroid Hormone (PTH): 102pg/ml. The diagnosis of a brown tumor of hyperparathyroidism was suspected. A parathyroid technetium scintiscan revealed abnormally high uptake a

Abstract:

Abstract Secondary hyperparathyroidism is a common complication of end stage renal disease (ESRD). The inherent impaired phosphorus and calcium metabolism result in altered bone metabolism, which rarely may manifest as osteitis fibrosa cystica with approximately 2% presenting as brown tumors. Brown tumors are areas of excessive bone resorption replaced by giant cells and fibrovascular tissue. Maxillofacial brown tumors are rare and result in increased patient morbidity due to associated nasal bleeding, diffuse pain and focal deformities. Nonetheless, these tumors are treatable and may regress

Abstract:

Hiperparatiroidisme (HPT) merupakan kondisi yang disebabkan oleh meningkatnya produksi dan sekresi hormon paratiroid (PTH). Tipe HPT diklasifikasikan menjadi tiga dan HPT tersier merupakan yang paling jarang terjadi. Kerusakan tulang merupakan komplikasi yang paling sering terjadi pada HPT tersier yaitu sebesar 25% dari total pasien HPT dan brown tumor merupakan salah satu bagian dari komplikasi tersebut. Lesi ini sering terjadi pada tulang kortikal, termasuk mandibula. Pemeriksaan klinis, radiografis, histopatologi, dan biokimia serum dilakukan dalam upaya diagnosis brown tumor. Perawatan bro

Abstract:

Searching for natural products with anti-tumor activity is an important aspect of cancer research. Seaweed polysaccharides from brown seaweed have shown promising anti-tumor activity; however, their structure, composition, and biological activity vary considerably, depending on many factors. In this study, 16 polysaccharide fractions were extracted and purified from three large brown seaweed species (Sargassum horneri, Scytosiphon lomentaria, and Undaria pinnatifida). The chemical composition analysis revealed that the polysaccharide fractions have varying molecular weights ranging from 8.889
