Abstract
Objective: Describe a case report of an apocrine hydrocistoma of unusual presentation site (nasal) and a literature review. Its pathogeny seems to be a result of the sudoriferous conduct obstruction just above the glandular wound, due to trauma or an inflammatory process.
Method: Female, 43 years-old, complaining of a swelling over the right side of the nose, associated to pain and nasal obstruction over 1 year. The examination showed facial asymmetry with an elevated right nasal wing and bulging of nasal floor. We performed cyst resection.
Results: This case shows a nasal apocrine hydrocistoma that differs from its usual eyelid location. The patient’s clinical and physical history, as well CT scan images, guided us to cyst resection with an intraoral access. The anatomopathology study proved to be an apocrine hydrocistoma. The literature review points this case report as a differential diagnosis for diseases in this area, such as inflammatory periapical lesions, nasal boils, nasopalatine duct cysts, dermoid cysts, and nasolabial cysts.
Conclusion: Apocrine hydrocistomas are sudoriferous gland benign tumors in the face. Most people present themselves with a well-delimitated swelling, local pain, and partial or complete nasal obstruction. CT is the ideal examination for its evaluation, with anatomopathology to confirm the diagnosis. Cyst resection is a choice treatment.
