Abstract. Lipomas of the sigmoid colon are rare entities. The present case describes a 27-year-old Caucasian woman who underwent a laparoscopic sigmoidectomy following the detection of a giant lipoma. The young patient was referred to the Emergency Department of the University Hospital of Heraklion (Crete, Greece) in May 2013 after experiencing intermittent abdominal cramping during defecation, and altering episodes of diarrhea and constipation. In addition, the patient described the protrusion of a solid tissue mass shaped like a 'champagne bottle cork' from the anus following defecation. These symptoms had been present for 1 month prior to referral. Physical examination was unremarkable. An urgent colonoscopy revealed a polypoid lesion measuring 2.5 cm in diameter in the sigmoid colon, which was located ~12 cm above the anal ring, with a smooth surface and tissue fragility. Tissue samples were obtained and sent for histopathological analysis. Preoperative contrast-enhanced computed tomography was performed urgently and confirmed the presence of a solid mass in the sigmoid colon without enlargement of regional lymph nodes. Following adequate preparation, the patient underwent a laparoscopic sigmoidectomy with intracorporeal termino-terminal colorectal anastomosis, with the use of a circular stapler. The patient had a positive post-operative outcome without complications and was discharged on day 4 post-surgery in an optimal condition. Histopathological examination of the surgical specimen demonstrated a pedunculated lipoma shaped like a 'champagne bottle cork'. The tumor consisted of mature adipose cells. The overlying colonic mucosa showed hyperplastic crypts with regenerative changes. In the lamina propria mild inflammatory infiltration was observed. At 2 years post-surgery, the patient remains asymptomatic without any clinical evidence of recurrence.

The aim of the present study was to assess the possible etiologic role of human papillomavirus (HPV), human herpes virus (HHV) and the human polyoma virus families (BKV and JCV) in the tumourigenesis of bladder cancer. Thirty biopsy specimens from patients with different grades and stages of bladder cancer, who underwent transurethral bladder cancer resection, and 30 normal bladder mucosa specimens were analysed using polymerase chain reaction (PCR) for the detection of the above three virus family members. The presence of HPV was determined in all specimens with nested PCR and real-time quantitative PCR. All cancerous specimens, including the control group, were found to be negative both by PCR and real-time qPCR for the presence of HPV DNA, whilst all samples examined by PCR tested negative for the presence of HSV-1,2 Varicella zoster virus and HSV-7 DNA. Cytomegalovirus, HHV-6 and HHV-8 exhibited similar incidence in sample positivity in both cancerous and healthy tissues. EBV showed a higher prevalence in bladder cancer specimens compared to healthy tissue (p = 0.048), whilst BKV and JCV were detected only in tumour samples. The presence of EBV in a significant proportion of bladder tumours indicates the etiological role of this virus in cancer tumourigenesis.

HighlightsExcessive drooping belly may lead to severe issues majorly affecting the person’s health as well as the quality of life.Abdominoplasty could be used not only for cosmetic purposes but also for therapeutic purposes by eliminating morbidity and improving the quality of life.

IntroductionCases of patients with inguinoscrotal hernia containing the urinary bladder are very rare. These patients usually present with frequent episodes of urinary tract infection, difficulty in walking, pollakisuria and difficulty in initiating micturition because of incarceration of the urinary bladder into the scrotum.Case presentationWe describe the case of an 80-year-old Caucasian man with an incarcerated urinary bladder into the scrotum who underwent surgical repair with mesh.ConclusionsDiagnosis of such cases often requires not only clinical examination but also specialized radiological examinations to show the ectopic position of the urinary bladder. Surgical repair in these patients is a real challenge for surgeons.
