Aggressive angiomyxoma is a rare, locally invasive tumor that generally affects the perineum and pelvis of reproductive age females. Aggressive angiomyxoma is often misdiagnosed, resulting in the delay of the treatment. Case reports show increased growth of the tumor during pregnancy, thus suggesting a hormonal dependency. We report this rare condition in a 29-year-old primigravid female with a...

Many clinical studies show that a sizeable proportion of male alcoholics are also inclined to act violently and aggressively. Given this association in humans, we asked whether a relationship exists between ethanol intake and aggressive behaviour in laboratory rats. In a first test of the hypothesis, we measured ethanol intake in male rats made aggressive by periodic contacts with sexually acti...

Aggressive angiomyxoma is a rare, myofibroblastic tumour, of pelvi-perineum of young women. It is a slow growing, low grade neoplasm with a high risk of recurrence following initial resection. Aggressive angiomyxoma is often clinically misdiagnosed because of its variable presentation as a soft tissue mass of the vulva, perianal region, buttock or pelvis. It displays translevator extension with...

One thousand two hundred pigs were weaned at 4 weeks of age and mixed to form groups of ten animals that were balanced for gender. The groups consisted of uniform weight groups (i.e. separate groups of small, medium or large pigs), or mixed weight groups (i.e. groups containing small, medium and large pigs). Half of the groups were retained from weaning until slaughter at 21 weeks of age, and h...

Cholera is on the rise globally, especially epidemic cholera which is characterized by intermittent and unpredictable outbreaks that punctuate periods of regional disease fade-out. These epidemic dynamics remain however poorly understood. Here we examine records for epidemic cholera over both contemporary and historical timelines, from Africa (1990-2006) and former British India (1882-1939). We...

The present study aimed to reveal the role of neuroticism on the relationship between self-esteem and aggressive emotion. We conducted a cross-sectional study in which a battery of self-report questionnaires was used to assess self-esteem, neuroticism and aggressive emotion in 1085 Chinese adolescents (N = 1085, Mage = 16.38 years, 753 boys). We found that self-esteem could make a negative pred...

BACKGROUND Aggressive angiomyxoma (AAM) is a rare soft tissue tumour usually of the perineum. There is no report in the surgical literature of a description of AAM in black Africans. OBJECTIVE To report the first description of AAM in black Africa women in the surgical literature and to highlight the value of special immunostains in the complete characterization these rare tumours. METHODS ...

Introduction. Aggressive angiomyxoma is a rare, slowly growing, and benign tumour of mesenchymal origin, which affects women of reproductive age and is associated with a high risk of local recurrence. Case Presentation. A case of a 47-year-old white female is presented herein, with a large polypoid, gelatinous mass on the right labia majora, measuring 26 × 21 × 6 cm. Histopathologically, the le...

Aneurysmal bone cysts are benign musculoskeletal tumours, which occur in young patients and, occasionally, with aggressive behaviour. Those tumours very often will need surgical treatment with curettage and bone grafting, but for aggressive lesions, inbloc resection is more advisable. Aggressive tumours use to be large and sometimes with difficult surgical approach and demanding complex surgica...

Aggressive angiomyxoma is a rare neoplasm which predominantly involves the female pelvis and perineum. Forty-four cases have been reported in the world literature, including 10 cases in men. To the best of our knowledge, the first case of recurrent aggressive angiomyxoma of the urinary bladder is presented here. Operative management, radiologic features and pathological findings are discussed.
