Abdominal wall schwannoma: a case report.

Schwannomas or neurilemmomas are benign and slow-growing tumors that arise exclusively from Schwann cells in peripheral nerve sheaths. These neoplasms theoretically can occur anywhere in the body, but they most frequently affect extremities, as well as head and neck region. However, their presentation in the abdominal wall is extremely rare and only few cases have been reported in the literature. Subcutaneous lesions may be asymptomatic and only incidentally discovered upon physical examination or imaging. However, occasionally they induce mass effects on surrounding large nerves. We present the case of a 34-year-old man with abdominal wall pain localized in the right iliac fossa and palpable subcutaneous mass. Ultrasound and CT scan revealed a solid well-defined mass of the abdominal wall. Following surgical excision under general anesthesia, histological examination was consistent with the diagnosis of benign schwannoma.

From headache to kidney tumor; an example of von Hippel- Lindau disease.

BACKGROUND: von Hippel-Lindau disease (VHL) is a rare genetic condition caused by the mutation of the VHL tumor suppressor gene and predisposing to various benign or malignant tumors involving mainly central nervous system (CNS) and retinal hemangioblastomas (RHB). Although considered as occult, multiple renal cysts and renal cell carcinoma (RCC) are frequent in VHL, occurring in nearly two-thirds of patients. RCC is the major neoplasm and the main cause of death in patients with this condition. CASE: In this report, we present a case of an occult kidney tumor revealed by neurological symptoms of cerebellar hemangioblastoma. CONCLUSION: Kidney tumor was diagnosed incidentally on abdominal tomography and confirmed by histopathology analysis.

Late care in marathon runs leading to exertional heat stroke with multiple organ failure.

BACKGROUND: Exertional heat stroke (EHS) is still a main cause of death in sport. Many of EHS complications could have been prevented if EHS had been recognized and treated early and properly. CASE PRESENTATION: We report an unusual case of multiple organ failure caused by EHS due to intensive sportive activities in a hot environment with lack of primary care. A 35-year-old healthy sportive man was admitted in our hospital because of muscle aches and weakness as well as dark urine three days after a six hour marathon run (Agadir Semi-Marathon) in a very sunny day. Patient developed rhabdomyolysis, acute renal failure (ARF) requiring hemodialysis because of hyperkaliémia, azotémia and severe metabolic acidosis, disseminated intravascular coagulation and acute liver failure. Unfortunately, after eight days of intensive care, the patient died from septic shock and multiple organ failure. CONCLUSION: This case reminds us that, despite the advancements of knowledge in the area of EHS prevention, recognition, and treatment, knowledge has not been translated into practice.
