BACKGROUND Primary mediastinal non-seminomatous germ cell tumors (NSGCTs) are aggressive and carry a poor five-year disease free survival rate even with aggressive treatment. We describe a young adult male with primary mediastinal NSGCT presenting with airway obstruction and superior vena cava syndrome (SVCS). CASE REPORT The patient presented with four weeks of nonproductive cough, weight loss, and right-sided pleuritic chest pain. Chest computed topography (CT) imaging demonstrated a right-sided mediastinal mass determined as a yolk sac tumor on biopsy...

Isaac Almendros, David Gozal
The deleterious effects of intermittent hypoxia (IH) on cancer biology have been primarily evaluated in the context of the aberrant circulation observed in solid tumors which results in recurrent intra-tumoral episodic hypoxia. From those studies, IH has been linked to an accelerated tumor progression, metastasis and resistance to therapies. More recently, the role of IH in cancer has also been studied in the context of obstructive sleep apnea (OSA), since IH is a hallmark characteristic of this condition. Such recent studies are undoubtedly adding more information regarding the role of IH on tumor malignancy...

Lymphangioma is a rare, benign mesenchymal neoplasm, which is characterized by numerous intercommunicating cystic spaces containing lymphatic fluid. It is considered a congenital disease resulting from the obstruction of regional lymph drainage during the developmental period. Lymphangioma frequently occurs in the cervical neck and axilla, also in the retroperitoneum, mediastinum, mesentery, omentum, colon, and pelvis, rarely in the perirenal space. These tumors usually present in childhood, but infrequently, these also present in adults...

Orbital surgeons are quite familiar with the diagnosis and management of paranasal sinus mucoceles due their frequent involvement of the orbit. These benign masses form and expand following sinus outflow obstruction secondary to various causes including trauma, inflammation and malignancy, amongst others. The authors present two cases of isolated orbital mucoceles without associated sinus outflow obstruction. There were notably no connections between the paranasal sinuses and the lesions. The mucoceles were diagnosed following orbitotomies and excisional biopsies with confirmatory histopathology...

BACKGROUND: Ventriculoperitoneal shunt (VPS) placement has been implicated in extraneural metastasis of many primary central nervous system tumors. Reported cases include, but are not limited to, medulloblastoma, germ cell tumor, astrocytoma, oligodendroglioma, lymphoma, ependymoma, melanoma, and choroid plexus tumors. However, a literature review reveals no reported cases of extraneural metastasis of solitary fibrous tumor/hemangiopericytoma (SFT/HPC). CASE DESCRIPTION: Here we report the case of a 34-year-old man with recurrent intracranial malignant SFT/HPC who had undergone surgical tumor resection and subsequent placement of a VPS for obstructive hydrocephalus in 2004...

Paraneoplastic pemphigus (PNP) is a rare, fatal, paraneoplastic autoimmune mucocutaneous blistering disease, commonly associated with lymphoproliferative disorders, including malignant lymphomas. Lymphoproliferative disorders associated with PNP are sometimes associated with a serious lung complication, bronchiolitis obliterans (BO). Due to its rarity, guidelines for the management of PNP have not been established. Furthermore, most patients die within 1 year. Here we report the successful treatment of lymphoma-associated PNP and BO using R-CHOP chemotherapy...

REVIEW
Paul A Bergamin, Anthony J Kiosoglous
There are many causes of recurrent urinary tract infections (rUTI) which are amenable to surgical management. This usually follows a lengthy trial of conservative management. Aetiological classification of rUTI requiring surgical management may be divided into congenital or acquired. Predisposing factors are classified into two groups; those providing a source for organisms, or by maintaining favourable conditions for the proliferation of organisms. Sources of infections include calculi, fistulae or abscesses...

BACKGROUND: The ureterointestinal anastomosis stricture (UAS) is a common complication of urinary diversion after radical cystectomy. For decades, open anastomotic revision remained the gold standard for the treatment of UAS. However, with the advancement in endoscopic technology, mini-invasive therapeutic approaches have been used in its management. Here, we report our experience with and long-term results of combined simultaneous antegrade and retrograde endoscopy (SARE) in the treatment of non-malignant UASs after urinary diversion in a consecutive series of patients...

Cutaneous metastasis of an internal malignancy is uncommon and is estimated to occur in 0.7-9% of patients with internal cancer including autopsy cases. We would like to report a case of long survival of sigmoid colon adenocarcinoma diagnosed as an instance of facial cutaneous metastasis. A 68-year-old male was admitted to our hospital for a tumor mass on the left side of his cheek. In his past history, acute myocardial infarction had occurred 2 years earlier. He also had chronic renal failure and chronic obstructive pulmonary disease...

PURPOSE OF REVIEW: Gastric outlet obstruction (GOO) can result from benign and malignant causes. Until recently, surgical gastrojejunostomy was the treatment of choice for patient with benign and malignant GOO with a good functional status. Endoscopic placement of luminal self-expandable metal stents is currently widely accepted as the first line of treatment for malignant GOO because of its effectiveness and minimally invasive nature. The main shortcoming of luminal stents is the high incidence of recurrent GOO most commonly because of tumor ingrowth/overgrowth...
