ceruminösadenom

Ceruminösadenom is a rare, benign tumor that arises from the ceruminous glands located in the external auditory canal. These glands are modified sweat glands that produce cerumen, commonly known as earwax. The condition typically presents as a slow-growing, painless mass within the ear canal, often causing symptoms such as ear fullness, hearing loss, or itching due to obstruction.

The exact cause of ceruminösadenom remains unclear, though it is believed to result from abnormal proliferation of ceruminous gland cells. Risk factors are not well-defined, but the tumor is more commonly diagnosed in adults, with no clear gender predilection. Diagnosis is usually confirmed through a combination of clinical examination, otoscopy, and histopathological analysis following a biopsy. Imaging studies, such as computed tomography (CT) or magnetic resonance imaging (MRI), may be employed to assess the extent of the lesion and rule out other potential ear pathologies.

Treatment primarily involves surgical excision, as ceruminösadenom is non-cancerous but may recur if incompletely removed. The procedure is typically performed under local anesthesia, and the prognosis is generally favorable with complete resection. Postoperative care may include ear cleaning and monitoring for signs of recurrence or complications, such as infection or hearing impairment.

Differential diagnosis includes other benign and malignant ear tumors, such as ceruminous carcinoma, seborrheic keratosis, or squamous cell papilloma. Given its rarity, ceruminösadenom should be considered in the context of other possible diagnoses, particularly when the clinical presentation is atypical. Early intervention is recommended to prevent potential complications related to prolonged obstruction of the ear canal.
