The case of an association of three well-differentiated pathologies is reported. A 40-year-old woman with a toxic thyroid adenoma developed acute polyarthritis during the course of the disease. The articular symptoms together with chest X-rays and a consistently negative PPD (1:100) were suggestive of sarcoidosis. This was later confirmed by the discovery of non-caseating granulomas in the liver and superficial lymph nodes, and by a positive Kveim's test. Histopathologic examination of the thyroid gland confirmed the existence of the adenoma. Sarcoid infiltration was not observed, but on the other hand the typical images of subacute granulomatous thyroiditis (De Quervain's thyroiditis) were discovered.

Tuberculosis (Tbc) presented as an isolated parotid mass is rare. Preoperative diagnosis is difficult and the symptomatology is nonspecific. In the majority of the cases an initial diagnosis of a parotid tumor, often a pleomorphic adenoma, is made. We present a 35-year old woman with a six months duration right parotid lump. The mass was firm and nontender without ipsilateral cervical lymphadenopathy, suggesting a parotid neoplasm. The computerized tomography scan showed an intraparotideal tumor resembling a pleomorphic adenoma and thus the patient underwent to a superficial parotidectomy. Fine needle aspiration biopsy was performed but it was not diagnostic. Histological examination revealed an intraparotideal lymph node with changes of granulomatous lymphadenopathy type, like those demonstrated in the tuberculosis and sarcoidosis. Ziehl-Nielsen staining was negative, while the tuberculin skin test (PPD, 5 IU) was positive. The patient's treatment regimen consisted of a 2-month initial phase of isoniazid, rifampin, pyrazinamide and ethambutol followed by a 7 month continuation phase of isoniazid and rifampin. Postoperatively, there was only a mild paresis of the facial nerve resolved a week after. Parotid Tbc is very rare but should be considered as a differential diagnosis of parotid lumps. Fine needle aspiration biopsy (FNAB) is of outmost importance for diagnosis, since the treatment of this entity is primarily conservative. However, surgery could be both therapeutic and diagnostic, especially when other diagnostic examinations fail.
