Ameloblastic fibroma of the jaw is a rare, benign mixed odontogenic tumor, having little tendency for local invasion and a low recurrence rate. Cytologic distinction from ameloblastoma, ameloblastic fibrosarcoma, and intraosseous adenoid cystic carcinoma is necessary, in view of the different biologic behavior. A painful, slow-growing swelling of the jaw in a 5-yr-old child clinicoradiologically considered as a benign cystic lesion was aspirated. Sheets of small monomorphic epithelial cells with peripheral palisading by columnar cells were seen on cytology smears. The striking feature was central hyaline globules in some tubules. A cytologic possibility of adenomatoid odontogenic tumor was suggested. Histopathology, however, confirmed it to be an ameloblastic fibroma. 相似文献

Hurler's disease, also known as mucopolysaccharidoses 1H, an autosomal recessive disease due to enzyme alpha-iduronidase deficiency has generally a spectrum of findings involving the eye, skeletal abnormality, organomegaly, joint stiffness, hernia, mental retardation and cardiovascular abnormalities. The two cases presented here are related to each other as brother of 9 years age and sister of 7 years of age with their parents had consanguineous marriage. On ocular examination in both the cases there was dense bilateral corneal opacities. Glycosaminoglycan's level was found to be 4 mg/mmol cr in the first case and 5 mg/mmol cr in the second case. In the first case no ocular treatment was planned and in the second case penetrating keratoplasty was the choice of management. 相似文献

A case of focal xanthogranulomatous pyelonephritis presenting as a circumscribed mass in a functioning kidney of a young male is described. Clinical, radiological, and cytological features closely mimicked renal cell carcinoma leading to radical nephrectomy. Peroperative findings and gross pathological features also corroborated preoperative diagnosis. The final diagnosis was a histologic surprise. It is an uncommon entity with cortical location, no pelvic communication, and progressively destroying the kidney. It should be considered in the differential diagnosis of any mass lesion at any age during preoperative clinicoradiological and cytological evaluation. A correct preoperative diagnosis can save unnecessary nephrectomy. 相似文献

Botryoid rhabdomyosarcoma, previously considered a type of embryonal rhabdomyosarcoma, has clinicopathological features distinctive enough to warrant its classification as a separate entity. It almost always occurs in children under 5 years of age. Two cases of botryoid rhabdomyosarcoma are reported here because of their relative rarity. 相似文献

BACKGROUND: Depression is a clinically heterogeneous disorder thought to result from multiple genes interacting with environmental and developmental components. A dimensional rather than a categorical approach to depressive phenotype definition may be more useful for identification of susceptibility genes. OBJECTIVES: To perform an exploratory factor analysis on a range of depressive and anxiety symptoms in a large, well-defined sample of depressed siblings, as well as a confirmatory factor analysis in a separate large group of unrelated depressed subjects, and to analyze correlations of identified symptom dimensions between depressed siblings. DESIGN: Subjects (N = 1034), including 475 sibling pairs, with a history of at least 2 depressive episodes were recruited from the Depression Network Study, a large-scale multicenter collection of families affected by recurrent unipolar depression. Subjects were interviewed using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) and diagnosed according to the DSM-IV and the International Classification of Diseases, 10th Revision, using a computerized scoring program (CATEGO5). Factor analysis was carried out on 26 depression symptom items, including 4 anxiety screening items. Confirmatory factor analysis was performed on an independent sample of 485 depressed individuals. RESULTS: Four interpretable factors were identified: (1) mood symptoms and psychomotor retardation; (2) anxiety; (3) psychomotor agitation, guilt, and suicidality; and (4) appetite gain and hypersomnia. For each symptom group, a quantitative scale was constructed, and correlations between siblings were calculated. There was a moderate degree of sibling homotypia for some depressive symptoms, and factors 1, 2, and 3 showed significant positive familial correlation (0.145 [P =.001], 0.335 [P<.001], and 0.362 [P<.001], respectively). CONCLUSIONS: This is the first study of large, well-defined samples of depressed subjects in whom symptom dimensions have been derived and then confirmed using independent material. The significant correlations between siblings for 3 of the dimensions suggest substantial familial, perhaps genetic, etiologies. 相似文献
