1/6. osteopetrosis presenting with paroxysmal trigeminal neuralgia. A case report.osteopetrosis is a rare disease of unknown aetiology. The relentless bone growth may progressively obliterate the various craniofacial skeletal foramina leading to nerve compression and a diversity of neurological disorders. A case is reported of a 37-year-old woman who was seen because of frequent attacks of paroxysmal trigeminal neuralgia (PTN); other orofacial neurologic deficits and generalised craniofacial skeletal thickening. The prompt recognition and management of associated disorders such as PTN is emphasized. Despite the lack of definitive treatment modalities for both osteopetrosis and PTN, the patient's quality of life must be sustained.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
2/6. Massive osteolysis of the maxillofacial bones. Report of two cases.Two cases of massive osteolysis were encountered, one affecting the mandible and the other the maxilla and mandible. Only 13 cases have been reported so far in the existing literature for massive osteolysis of the mandible. It is indeed a rare disease. Our two cases were surgically treated and were clinically and histopathologically assessed.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
3/6. histiocytosis X: current concepts and a report of two cases.The current concepts of histiocytosis X are discussed, and the literature concering this rare disease of obscure aetiology reviewed. Two case reports of histiocytosis X presenting in similar sites in young children of similar ages, but with markedly different courses, are presented. The importance of early recognition of the disease, particularly by the dental surgeon who may see the first oral signs, is stressed. attention is drawn to the danger of misdiagnosing the oral signs of histiocytosis X, particularly as periodontal disease. The possible aetiologies are examined and current treatment regimes discussed.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
4/6. Massive osteolysis of the mandible.This report deals with a massive osteolysis, which is a rare disease characterized by the progressive dissolution of contiguous osseous structure, occurring in the mandible of a 46-year-old Japanese female. Histopathologic examination of the amputation material revealed that the mandibular body, ramus, condylar and coronoid processes were completely replaced by fibrous tissue, but inferior alveolar nerve and artery in the lesion were intact. A few small islands of osteoid tissue or immature fibrous bone were seen in the lesion. In the transitional area between the lesion and normal bone, active absorption of bone trabeculae was in progress and intertrabecular spaces were occupied by densely packed fibroblastic cells, however, angiomatous proliferation of vessels was not observed. A few bone trabeculae were surrounded by osteoclasts, but osteoclasts might not play a primary etiological role in massive osteolysis.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
5/6. osteomyelitis of the mandible. An initial feature in late-onset osteopetrosis.osteopetrosis is a rare disease that may be seen with numerous disorders referable to the head and neck. It occurs in both a malignant and a benign form. The benign form is consistent with a long life span and, when clinically manifest, often does so as osteomyelitis of the mandible. An awareness of this association greatly simplifies diagnosis through standard osseous roentgenograms. The findings of osteopetrosis so characteristic on standard osseous roentgenograms may be inapparent if only mandibular roentgenograms are obtained.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
6/6. Langerhans cell histiocytosis of vulva and cervix in a 19-year-old woman.Langerhans cell histiocytosis of the female genital tract is a rare disease. A clinical diagnosis is impossible to establish because no typical lesions are found. immunohistochemistry of bioptic samples is the easier technique to obtain the correct diagnosis. We present a case of a 19-year-old woman with Langerhans cell histiocytosis of mandible and maxilla with subsequent cervical and vulvar histiocytosis.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
