Complication of the benign Mediastinal tumor are malignant change, infection, bleeding, local invasion and heart and lung compression. Because of these complications the patients can bring grave clinical course and results. With only early diagnosis and adequate management can protect from these complications and bring good results. In the BNU hospital during the period of 22 years, from 1956 to 1976, managed 35 cases of benign Mediastinal tumors. Among these 35 cases, we selected 21 cases which are in exact clinical record and did clinical analysis. Age distribution was from 6 years to 68 years and the mean age was 28.8 years. Male to female sex distribution was 62% to 38%, and was male predominant.
Age distribution of the tumor according to tissue pathology was as follows; Neurogenic tumors are distributed through whole age range, Cysts are distributed to teen agers and thirties, Teratodermoids are distributed to teen agers and twenties and Lymphoma appeared before thirties. Characteristic locations of the tumors according to the tissue pathology in the Mediastinum are as follows; in the Superior Mediastinum located Cysts, Teratodermoids, Thymomas in this order, in the Anterior Mediastinum located Teratodermoids, Cysts, Thymomas, in the Middle Mediastinum located Cysts, Teratodermoids, Neutogenic Tumors, in the Posterior Mediastinum there located only Neurogenic Tumors. 28.5 percent of the patients haven´t any symptoms of signs. The symptoms were 22.8% chest pain, 22.8% dysphagia 22.8% fatigue.
The signs were 47% weight loss, 17.6% dysphagia in this order. After developing the symptoms of signs, 47% of the patients were diagnosed within one month, and 80% of the patients were diagnosed withing 3 month.
The complications of the benign Mediastinal Tumors were developed in 6 cases out of 21 cases, this means 28.5% complications.
In operation, all of the benign Mediastinal Tumors were removed. One was removed along with lung lobe resection and one was expired during operation because of very poor general condition.
