Primary mediastinal seminoma is a relatively rare tumor usually located in the anterior mediastinum. We report here an extremely rare case of a 66-year-old man with primary seminoma in the middle mediastinum. A physical examination showed lymphadenopathy in the right supraclavicular area. A chest CT confirmed the presence of a tumor occupying the retrotracheal space. A histological examination ...

Malignant triton tumors (MTTs) are a rare subtype of malignant peripheral nerve sheath tumor (MPNST) showing rhabdomyoblastic differentiation, which have no treatment consensus and a poor prognosis. This case report presented the case of a 42-year-old male patient with a large MTT located in the anterior mediastinum. The patient underwent palliative chemoradiotherapy and interstitial chemothera...

Leiomyosarcoma of the mediastinum and primary leiomyosarcoma of the spine are exceedingly rare. In most cases, spinal leiomyosarcoma is metastatic. In this report, we describe the case of a 58-year-old man who presented with a large leiomyosarcoma of the posterior mediastinum that extended into the adjacent spinal canal. The tumor was completely resected from the mediastinum, but only subtotall...

Neurogenic tumors are the most common type of mediastinal tumor and constitute the majority of neoplasms of the posterior mediastinum. Schwannomas originating from the intrathoracic vagus nerve are extremely rare. The present study describes the case of a 58-year-old man with a large vagal schwannoma in the left superior mediastinum. A large tumor with a round shape was identified in the left s...

The mediastinum is a unique anatomic area containing various structures and pluripotent cells, which allow for the development of a range of tumors. We report two pediatric cases of a lipomatous tumor of the posterior mediastinum. Complete surgical excision of the mass in each was achieved through a lateral thoracotomy. Histopathologic findings showed a lipoma in one case and a lipoblastoma in ...

Musculoskeletal tuberculosis accounts for 1-2% of all types of tuberculosis. Tubercular abscess of the chest wall accounts for 1-5% of all cases of musculoskeletal tuberculosis. Herein, we report a case of tubercular abscess of the chest wall. The occurrence of caries rib and cold abscess of the chest wall with concomitant pulmonary tuberculosis, and tubercular lympha-denitis of neck and medias...

Experimental studies were undertaken, aiming at evaluation of lymphatic drainage from the peritoneal cavity to lymph nodes of the cranial mediastinum in rats. The study made use of 11 adult male Wistar rats. For examination of lymphatic structures drawing ink and FITC-dextran, administered intraperitoneally, were used. Due to lack of unambiguous terminology quoted in the literature with regard ...

The rarity with which cystic hygroma occurs in, and is confined to, the mediastinum justifies the report of a further case. Gross and Hurwitt (1948), after a careful review of the literature, were able to find only seven cases which they regarded as undoubted cystic hygromata, and they added a further one of their own. The author has excluded one of the cases collected by these authors, namely ...

Enterogenous cyst of the mediastinum is not a common condition. According to Bickford (1949) 40 cases have been reported. Of these, 24 were lined by purely gastric mucosa (this includes the case reported by him), four had purely intestinal epithelium and 12 were composite. This paper is presented as a further instance of an enterogenous cyst which was removed successfully at thoracotomy. Case H...

Presence of thymus in the normal position as well as in the posterior mediastinum is an unusual phenomenon. We report here a case of posterior mediastinal mass in a 20-month old male child who presented with dysphagia and dry cough. Investigations revealed it to be a solid posterior mediastinal mass, suspected to be either lymphoma or a neuroblastoma. Excision of the mass followed by histopatho...
