| Sumario: | Purpose: Adenoid cystic carcinoma (CAQ) it is a rare malignant tumor of salivary glands. Its extra salival location is even rarer and only few cases that compromise the nasal cavity and paranasal sinuses were reported in literature. The objective of this work was to perform the clinical, histological and imaging study of a CAQ of nasal cavity. Methods: Female patient of 54 years old who in 2015 consulted for a tumor in the region of the left nasopalpebral sulcus of diffuse limits, fixed and hard, with mild pain on palpationof 6 months evolution. Computerised axial tomography (TAC) and nasal cavity endoscopy were indicated, the results of which determined surgical resection. The postoperative biopsy was analyzed with H / E and Masson's trichrome. Results: In the TAC, an isodense image of defined limits was observed, in the nasal cavity and left lacrimal-nasal duct with bone lysis of the nasal septum, anterior end of the middle meatus, bones of the nose and maxillary, with invasion of the maxillary sinus and soft tissues. Nasal cavity endoscopy revealed a lesion in the space between the superior and middle turbinates and the nasal septum. Tumor resection was performed with safety margins. The histopathological report indicated CAQ with cribiform pattern that invaded bone. The patient underwent postoperative radiotherapy. At present, it does not present tumor recurrence in the control TAC. Conclusions: Its periodic control is recommended because nasal and paranasal tumors compared with those of other head and neck sites are associated with a worse prognosis. |
