RESUMO
Teratomas are rare tumors in the mediastinum. Benign cystic teratomas of anterior mediastinum are rarely complicated by rupture into an adjacent body cavity. Such rupture, however, is usually associated with life-threatening complications. We present a case with spontaneous rupture of mediastinal cystic teratoma. The patient was evaluated with chest radiograph, computed tomography (CT) and magnetic resonance imaging (MRI). A complex mass including predominantly cystic components was detected in the left anterior mediastinum. After surgery, pathologic diagnosis was reported as mature cystic teratoma. High levels of amylase and lipase were detected in both the cystic fluid and serum. This finding supported the hypothesis of autolysis for the explanation of rupture. In addition, carbohydrate antigen (CA) 19-9, CA 125 and carcinoembryonic antigen (CEA) levels were high in the cystic fluid.

Dermoid and epidermoid cysts are developmental lesions that occur in the head and neck with an incidence ranging from 1.6 to 6.9%, and they represent less than 0.01% of all oral cavity cysts. We present a case of sublingual dermoid cyst in a 19-year-old male with ultrasound and MRI features and review the literature.

Testis tumors are extremely rare tumors, especially if they are bilateral, interstitial tumors. We present a case with bilateral Leydig cell tumors, which were detected incidentally. First, radical left orchiectomy was performed and pathologic diagnosis was Leydig cell tumor. One week later, partial right orchiectomy was done. The diagnosis was the same. After the 12-month follow-up, no recurrence or metastasis was detected. We suggest organ-sparing surgery as an alternative in the treatment of bilateral Leydig cell tumors especially for young males, since this surgical approach prevents hormonal replacement therapy and maintains fertility and potency.
