1/9. Verruciform xanthoma associated with squamous cell carcinoma.Verruciform xanthoma (VX) is a rare lesion of unknown etiology that is typically solitary and predominantly located within the oral cavity. Less commonly, they arise on the skin, with the majority of cases occurring in anogenital sites. They can be confused clinically with verruca vulgaris, condyloma, leukoplakia, verrucous carcinoma, and squamous cell carcinoma. Histologic features include acanthosis with uniform elongation of the rete ridges and xanthomatous cells that lie in and are typically confined to the papillary dermis. Although epidermal atypia is not a characteristic finding, we describe an unusual case of VX that has features of both VX and squamous cell carcinoma. In addition, there was a VX with typical histologic characteristics located at a separate site in the same patient. This case is also the first to our knowledge to be reported on the neck and axilla and is the third case associated with cutaneous graft versus host disease secondary to bone marrow transplant for acute lymphoblastic leukemia.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
2/9. Juvenile xanthogranuloma of the nasal cavity.Juvenile xanthogranuloma is a benign, normolipaemic, self-healing condition and a type of histiocytosis that occurs most frequently in infants and children. This condition usually presents with solitary or multiple cutaneous lesions and occasionally with visceral lesions. We report a case of juvenile xanthogranuloma occurring in the nasal cavity. We believe this is the first report, in the English literature, of juvenile xanthogranuloma occurring in this site.- - - - - - - - - - ranking = 0.28658674155366keywords = cavity (Clic here for more details about this article) |
3/9. Giant orbital and intracranial xanthogranuloma--a short report.Xanthogranuloma are known to arise in the paranasal sinus or orbit. They may also arise primarily in the brain. Those arising from the sinuses or orbit might involve the intracranial cavity to some extent. But an extensive involvement of the cranial compartment is very rare. This report describes one such case.- - - - - - - - - - ranking = 0.057317348310732keywords = cavity (Clic here for more details about this article) |
4/9. Juvenile xanthogranuloma of the nasal cavity.Juvenile xanthogranuloma (JXG) is the most common non-Langerhans histiocytosis, but it rarely occurs extracutaneously. It sometimes presents with associated neurofibromatosis and Juvenile chronic myalogenous leukemia. We present a case of nasal JXG and discuss the histological characteristics, the classification, and the management.- - - - - - - - - - ranking = 0.22926939324293keywords = cavity (Clic here for more details about this article) |
5/9. Juvenile xanthogranuloma invading the muscles in the head and neck: clinicopathological case report.Juvenile xanthogranuloma (JXG) is a member of the non-Langerhans cell group of histiocytic proliferative disorders. It typically presents as a solitary, benign, rapidly growing cutaneous tumor that may regress spontaneously. Most cutaneous lesions of JXG occur in the head and neck region of infants and young children. JXG has been documented in many visceral locations including the lung, bone, testis, gastrointestinal tract, kidney, heart, eye, and oral cavity. Intramuscular location is extremely rare. The few intramuscular lesions that have been described involve the trunk, with the musculature of the back involved most frequently. The authors present a patient with juvenile xanthogranuloma on her chin deeply invading the underlying facial muscles. Histopathological analysis confirmed the intramuscular extension. To the authors' knowledge, this is the first detailed clinicopathological report of juvenile xanthogranuloma infiltrating the muscles in the head and neck.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
6/9. Juvenile xanthogranuloma of the pelvic origin: a case report.A case of juvenile xanthogranuloma (JXG) originating from the pelvic cavity is reported. The patient, a 4-month-old girl, was referred to our department for the examination and treatment of her left abdominal mass. As radiological studies strongly suggested the possibility of a malignant tumor of muscular origin, tumor extirpation was performed. The tumor was buried in the left psoas muscle. Histological examination showed the tumor consisted of polygonal cells containing small vacuoles with scattered Touton giant cells, and the diagnosis of JXG was made. To our knowledge, this is the first case of a pelvic JXG.- - - - - - - - - - ranking = 0.057317348310732keywords = cavity (Clic here for more details about this article) |
7/9. Juvenile xanthogranuloma of the oral cavity: a case report.A 3 1/2-year-old girl presented with a symptomless lump on her tongue which had been present for 8 months. A provisional diagnosis of fibroepithelial polyp was made and no treatment was carried out. Six months later the lump had increased in size and it was excised. Histological examination led to a diagnosis of juvenile xanthogranuloma. One year later the lesion had not recurred.- - - - - - - - - - ranking = 4keywords = oral cavity, cavity (Clic here for more details about this article) |
8/9. Intraoral juvenile xanthogranuloma. A case report and literature review.Juvenile xanthogranuloma rarely occurs in the oral cavity and has received little attention. A case of histologically documented juvenile xanthogranuloma of the oral cavity is described. This is the first intraoral case reported in the Oriental race and in the vestibule. Pertinent literature regarding intraoral lesions of this condition is also reviewed.- - - - - - - - - - ranking = 2keywords = oral cavity, cavity (Clic here for more details about this article) |
9/9. Juvenile xanthogranuloma occurring in the oral cavity: case report and histopathological findings.Juvenile xanthogranuloma is commonly seen in the dermis, and only very rarely develops in the oral mucosa. Here were report a case that occurred in the anterior palate of a 9-year-old boy. The lesion appeared as a dark red and well-defined nodule measuring 12 x 14 mm. Histologically, it consisted of a proliferation of histiocytes and fibroblastic stroma intermingled with foamy cells. Many lipid droplets without limiting membrane were observed in the cytoplasm under electron microscopy, but no Langerhans' cell granules were observed. The proliferative histiocytes were positive for lysozyme and macrophage HAM56 under immunohistochemical observation, but not for S-100 protein. From these findings, the lesion was diagnosed as juvenile xanthogranuloma. The post-operative course, now amounting to 7 years, has been uneventful.- - - - - - - - - - ranking = 4keywords = oral cavity, cavity (Clic here for more details about this article) |
