Paraneoplastic pemphigus (PNP) is an autoimmune bullous disease associated with underlying neoplasms, both malignant and benign. The most constant clinical presentation of PNP is the presence of intractable stomatitis. Herein we present a 25-year-old male with a 3-month history of refractory stomatitis especially involving the lips and widespread vesiculobullous eruption on his trunk and extremities. The diagnosis of PNP was confirmed based on histological and serological results. Investigation for the underlying neoplasm revealed a retroperitoneal tumorous mass which was biopsied and diagnosed as the inflammatory myofibroblastic tumor (IMT)...

OBJECTIVE: Most of the ovarian cancers are diagnosed at advanced stages. As peritoneal carcinomatosis increases, especially when it extends to the diaphragm and intestinal mesos, probability of obtaining complete cytoreduction is reduced. Complete cytoreduction (residue zero: R0) is one of the main factors affecting survival [1-3]. Here we present a novel technique of stripping the peritoneal surfaces as a part of cytoreductive surgery in such cases. METHODS: A 55year-old woman diagnosed with peritoneal carcinomatosis was considered appropriate for primary cytoreduction after assessment of her thorax-abdominopelvic tomography, which revealed resectable intra-abdominal disease...

Extragonadal teratoma originating from the retroperitoneum represents less than 5% of all teratomas and accounts for less than 10% of all pediatric retroperitoneal neoplasms. To date, there has been no report of teratoma managed with LT. This study reports an infant aged 3 months with retroperitoneal immature teratoma involving the hepatic hilum, refractory to chemotherapy and treated with LT. The patient was referred to our hospital for management of a growing abdominal mass. Histopathology of a fine needle biopsy of the lesion suggested the possibility of a hepatoblastoma with teratoid features...

Carcinoid syndrome is the constellation of symptoms mediated by humoral factors produced by some carcinoid tumors. It consists primarily of vasomotor symptoms, gastrointestinal hypermotility, hypotension, and bronchospasm, due to the production and release of vasoactive substances. Carcinoid heart disease occurs in more than 50% of patients with carcinoid syndrome; in some cases, it represents the initial manifestation of the disease. We report the case of a 75-year-old woman with a metastatic neuroendocrine tumor admitted to the emergency room for fatigue and heart failure...
