Purpose: To evaluate the clinical and radiographic features of unilateral hyperplastic mandibular condyles for some useful preliminary diagnostic recommendations. Materials and Methods : Clinical records, radiographs and histologic diagnoses of 35 cases with asymmetric mandibular condyles due to apparent unilateral condylar hyperplasia were evaluated retrospectively. Results: Among 35 cases, 28 were true hyperplastic conditions of condyles whereas the remaining 7 were unilateral internal derangement occurring on the short side. 17 of the 28 hyperplastic condyles showed a mass or irregular radiographic shadow with histologic diagnosis including osteochondroma and osteoma. Only 5 of these cases showed facial asymmetry. 2 out of the 17 cases showed hyperplastic round shaped irregular condyles consistent with ankylosis and their histologic diagnoses were osteochondromas. 11 of the 28 cases showed smooth enlargement of condylar head with elongation of the neck causing facial asymmetry, but histologic diagnoses were not available because the surgical operation conserved the condyles. Conclusion: The hyperplastic conditions of the mandibular condyles include not only true hyperplasia, osteochondroma, osteoma, and ankylosis, but also unilateral internal derangement occurring on the short side.

Giant lymph node hyperplasia (Castleman's disease) is a nonneoplastic lymphoproliferative disorder of unknown etiology that usually occurs in the chest. Its morphological recognition is based on a composition of various histological features. The mass is often asymptomatic, but it can cause nonspecific thoracic symptoms, such as regional pain. This disease can be found wherever lymph nodes are present, but two-thirds of these tumors are found in the chest, along the tracheobronchial tree in the mediastinum or lung hilus. However, we experienced an unusual case of Castleman's disease as a cause of back pain that was localized in the posterior mediastinum bordering the chest wall.

Benign hyperplasia of hilar lymph glands is rare. Most of the lesions were intrathoracic cavity. The lesions were discovered most often on routine roentgenograms of the chest or because. of pressure symptoms or the presence of a palpable mass if outside the thorax. Diagnosis is. made after removal of gland, a procedure which may also have therapeutic value. They have been divided into 2 histol0gic types: the hyaline-vascular lesions, which were, most numerous, were characterized by small hyaline-vascular follicles and interfollicular capillary proliferation ;the plasma cell lesions were characterized by large follicles with! intervening sheets of plasma cells. We experienced one case of benign hyperplasia of lymph gland in left hilum, which were. most numerous, characterized by small hyaline-vascular follicles and interfollicular capillary proliferation-hyaline-vascular type. This 29 years old male patient was treated by right upper lobectomy with excision of lesion. The postoperative courses was uneventful.

Atypical adenomatous hyperplasia is a premalignant lesion reflecting a focal proliferation of atypical cells. These lesions are usually observed as incidental findings in lungs that have been resected due to other conditions, such as lung cancer. We report the youngest case of atypical adenomatous hyperplasia on record in a 12-year-old girl. In this patient, the lesion was found in association with pneumothorax.

Testicular adrenal rest tumors are a well-known complication in male patients with congenital adrenal hyperplasia. Corticosteroid suppressive therapy usually results in the regression of these tumors. We describe a patient with 21-hydroxylase deficiency who developed bilateral testicular masses. Despite steroid suppressive therapy, the tumors did not regress and hormonal control was poor. Consequently, bilateral partial orchiectomies were performed.

Thymus gland is a kind of endocrine organ which secretes thymosin and thymoprotein. There can be developed variable lesions like thymoma, thymic hyperplasia, thymic cyst, thymolipoma, and carcinoid tumor of the thymus gland. We have experienced 25 patients of thymic disease: thymoma 12, thymic hyperplasia 11, thymic cyst 1, carcinoid tumor 1. The age distribution were ranged from 3 to 66 years and the sex ratio was 1:1.8 [male to female]. Thymectomy was performed in all cases, but 3 cases with deep infiltration to the adjacent structures were not resectable completely. Malignancy [all thymoma] were 5 and the rest were benign. Two cases were died of recurrence after tumor resection. Myasthenia gravis occurred in 10 cases. Among them, 2 were thymoma and 8 were thymic hyperplasia. We could obtained the result that thymectomized cases reached 2 remission and 5 improvement. Myasthenia gravis treated medically [18 cases] had no remission and only 2 clinical improvement. In the light of these results, early radical thymectomy would be most favorable treatment in not only thymic tumor, but generalized myasthenia gravis.

Condylar hyperplasia (CH) is a rare disorder characterized by excessive bone growth that almost always presents unilaterally, resulting in facial asymmetry. Classification of the different types of CH can differ depending on the authors. Correct diagnosis is critical in determining the proper treatments and timing. This paper is a review of the recent literature on the epidemiology, etiology, diagnosis, classification, and surgical treatments of CH.

Intravascular papillary endothelial hyperplasia (IPEH) known as Masson's hemangioma is a rare benign reactive vascular lesion caused by the abnormal proliferation of endothelial cells. The lesion occurs most commonly in the fingers, head and neck, but very rare in the foot. We report a case of IPEH in the foot treated with operative excision.

Background: This case report discusses the unusual presentation of limited mouth opening as a result of bilateral coronoid process hyperplasia. Case presentation: A 14.5-year-old male patient of white Caucasian ethnicity presented with limited mouth opening, mandibular asymmetry, and dental crowding. Investigations confirmed bilateral coronoid process hyperplasia and management involved bilateral intraoral coronoidectomy surgery under general anaesthesia, followed by muscular rehabilitation. Mouth opening was restored to average maximum opening within 4 months of surgery. Conclusion: Limited mouth opening is a common presentation to medical and dental professionals. The rare but feasible diagnosis of coronoid impingement syndrome should not be overlooked.

Intravascular papillary endothelial hyperplasia or Masson's hemangioma is a rare vascular tumor. The reactive proliferation of endothelial cells in this disease mimics other benign or malignant vascular proliferation such as angiosarcoma or Kaposi's sarcoma. It is important to make an accurate distinction to avoid confusion with these malignant tumors. This would facilitate a proper diagnosis, which is essential so that the patient is not subjected to unnecessarily aggressive or inappropriate treatment.
