Дифференциальная диагностика церуминомы наружного слухового прохода

Abstract

In modern otorhinolaryngology, the problem of tumor diseases of the outer ear is relevant due to their diversity and insufficient knowledge. The aim of the work is to reveal the problem of differential diagnosis of ceruminoma of the external auditory canal, which causes difficulties due to the low frequency of occurrence and the absence of pathognomonic symptoms. Ceruminoma is a benign, slowly growing tumor of the sulfur glands. The article presents a clinical analysis of the case of a patient with ceruminoma. Diagnosis and choice of surgical treatment technique required certain efforts and the need for differential diagnosis. According to the result of CT scan of the temporal bones and brain with contrast, the doctor of radiation diagnostics suspected a glomus tumor of the left external auditory canal. Given the atypical localization and clinical picture, an additional MRI with intravenous contrast was performed. As a result of the differential diagnostic search, a clinical diagnosis was established: a benign neoplasm of the external auditory canal on the left, presumably ceruminous adenoma. The patient underwent successful surgical treatment. The result of the pathological and histological examination allowed us to confirm the diagnosis. Thus, ceruminoma is a rare neoplasm of the external auditory canal. The absence of specific clinical manifestations, complaints in the initial stages makes early diagnosis difficult. To make a diagnosis, the degree of germination and to determine the tactics of surgical treatment, it is necessary to conduct radiation diagnostics: CT and MRI of the temporal bones with an adequate interpretation of the results. An analysis of the results of morphological methods for examining the surgical material allows both verifying neoplasms and determining the prospects for a long-term postoperative period.
