However, in other instances the diagnosis of verrucous carcinoma may have been missed because of the unfamiliarity of many clinicians and pathologists with the morphologic characteristics of these lesions. We describe the first case of...
متن کاملAir-And Bone-Conduction Auditory Brainstem Response in Children with Congenital External Auditory Canal Atresia
Results: ABR threshold for air and bone conduction were 66.53 ± 7.12 and 12.55 ± 6.96 dBnHL, respectively, in children with congenital EACA, as well as 25.32 ± 2.66 and 10.71 ± 4.51 dBnHL, respectively, in children with normal hearing. The two groups showed statistical difference in air-conduction ABR thresholds. Meanwhile, air–bone ABR threshold gap was greater in children with EACA than in ch...
متن کامل[Glandular tumors of the external auditory canal].
Glandular tumors of the external auditory canal are rare; their etiopathogenesis is uncertain. The term ceruminoma, often used for these tumors, is imprecise. The 1978 who classification is reviewed. The authors describe their experience with 5 cases which illustrate the salient diagnostic therapeutic, and prognostic characteristics of these tumors.
متن کاملSyringocystadenoma Papilliferum of the External Auditory Canal

The neoplastic transformation of these structures is very rare and there have been few cases reported in the literature. CASE REPORT Syringocystadenoma papilliferum is one of the rarest tumors among benign tumors aris...
