摘要：Background: the granular cells tumors are uncommon benign lesions of slow growth that can appear in any place of the organism. The head and neck region includes the most frequent localizations (between the 30 and 50% of all the tumors of this type, including those of the central nervous system). Objective: to present a case of intra-thyroid granular cell tumor. Clinical case: a case of a 37 year-old female patient with nodular illness of the thyroid of slow growth with scarce symptoms, with histologic confirmation of granular cells tumor is presented. To the physical exam, an increase of volume was identified in the anterolateral region of the neck, in connection with the right lobe of the thyroid gland that corresponded with a tumoral lesion of 3cm approximately, not well defined, stuck to deep planes, not painful to the palpation. In the echography, it was observed: right lobe of the thyroid of 4.3 cm x 1.2cm x 1.4 cm, not homogeneous with a nodular lesion of 2.8 x 1.4 cm not well defined, of irregular borders. During the surgery, a frozen section was examined and reported as positive of malignancy, however, the untimely histologic study revealed a benign intra-thyroid granular cell tumor. The surgical treatment is healing in this case. Conclusions: the diagnosis of intra-thyroid benign granular cell tumor is presented with the characteristics of a malign tumor, it should be kept in mind in the differential diagnosis of the tumors of the thyroid.
