Images in clinical medicine. "Cotton wool" appearance of Paget's disease

The Skinner Burial of Ontario, Canada, and the Question of Paget's Disease in the Americas

PURPOSE

To examine a possible case of Paget's disease of bone (PDB) in an Indigenous pre-contact male from Canada, individual D of the Skinner site in Ontario.

METHODS

Radiographs, CT scan and histological analysis.

RESULTS

The histological analysis revealed the mosaic pattern that characterizes PDB. CT scans show advanced sclerosis of the cranium and a diminished diplӧe with osteolytic lesions.

CONCLUSIONS

The pathological features that have been identified are collectively characteristic of PDB.

SIGNIFICANCE

The Skinner case advances our understanding of the global history and distribution of PDB.

LIMITATIONS OF STUDY

Only two New World cases have been identified and neither has been studied in sufficient detail.

SUGGESTIONS FOR FUTURE RESEARCH

The older individuals in precolonial New World skeletal series should be given CT scans, which are non-intrusive, to be followed by histological and genetic analyses when indicated.

Paget's Disease: Skeletal Manifestations and Effect of Bisphosphonates

BACKGROUND

Paget's disease of bone leads to change in the shape and size of the bone and results in reduced bone strength, leading to the complications of deformity, arthritis, and fracture. Due to unknown reasons, Paget's disease is rare in Asian descendants. We report the cases of Paget's disease who visited our institute for 15 years and reviewed the literatures.

METHODS

We retrospectively reviewed the medical records and radiograms of 8 patients (6 female and 2 male) who were diagnosed as Paget's disease of bone. Diagnosis was confirmed by typical radiological feature in the involved skeletons and/or pathologic findings.

RESULTS

Pelvis, skull and spine were three most frequently involved bones. All involved bones in our cases showed changes in shape and trabecular pattern which resulted in bowing of lower extremity, secondary osteoarthritis, compression fracture of spine and enlargement of skull. Mean follow time was 4.71 years and all patient were treated bisphosphonate (BP). Use of BP controlled the level of serum alkaline phosphatase level effectively.

CONCLUSIONS

We have reviewed eight patients who were previously diagnosed as Paget's disease of bone in our institute. We could identify typical radiologic and clinical findings such as bowing deformity of long bone, secondary osteoarthritis, compression fracture and osteomyelitis of mandible that deteriorated the quality of their living.

Paget disease of bone: A classic case report

Paget disease of bone (PDB) is a chronic progressive disease of the bone of uncertain etiology, characterized initially by an increase in bone resorption, followed by a disorganized and excessive formation of bone, leading to pain, fractures, and deformities. It can manifest as a monostotic or polyostotic disease. The prevalence of PDB is common in the Anglo-Saxon population, but relatively rare in India. The disease is often asymptomatic and commonly seen in an aging population. The diagnosis of the disease is mostly based on radiological examination and on biochemical markers of bone turnover. Markedly elevated serum alkaline phosphatase (SAP) is a constant feature while calcium and phosphate levels are typically within normal limits. It is being successfully treated by biphosphonates, a group of anti-resorptive drugs, thereby decreasing the morbidity and mortality associated with the disease. We report a classic case of PDB with craniofacial involvement resulting in Leontiasis Ossea (lion like face), cotton wool appearance of the skull and elevated SAP.

Periodontal management in Paget's disease: Case presentation and a brief review of literature

Paget's disease of bone is a common condition characterized by increased and disorganized bone turnover which can affect one or several bones throughout the skeleton. These abnormalities disrupt normal bone architecture and lead to various complications such as bone pain, osteoarthritis, pathological fracture, bone deformity, deafness, and nerve compression syndromes. Genetic factors and environmental factors like paramyxovirus infection have been implicated in etiology. This is a case report of a patient who presented with Paget's disease and the periodontal surgical management, after the pretreatment was employed with diagnostic procedures like computed tomography and serum alkaline phosphatase tests.

From the editor's desk: Why still write a case report?

Case reports remain an invaluable resource in the literature, and they continue to serve an equally important role in scientific advancement. They record discoveries, report the unexpected, and spark further research. Preparation of a case report can be a great learning experience, especially for medical students, residents, and young physicians. It serves as an excellent introduction to academic writing, familiarizing them with all aspects of publishing, from a structured case presentation and literature review to submitting and revising a manuscript. It can also stimulate an interest in a specific topic and gradually lead to more involved and complex academic endeavors.
