Giant urothelial carcinoma of unknown origin invading the sigmoid mesocolon – a case report

BackgroundTransitional cell carcinoma, also called urothelial carcinoma, is the most common malignancy of the urinary bladder. Additionally, it can develop in the lining of the renal pelvis, ureter, prostate and urethra. Exceptionally, cancer can arise from the urachus. Also primary transitional cell carcinoma of the endometrium or ovary is a rare entity.AimThe aim of this article was to present a case of giant urothelial carcinoma of unknown origin invading the sigmoid mesocolon.Case ReportWe report a rare case of urothelial carcinoma invading the sigmoid mesocolon in a 60-year-old female admitted to our department. The patient presented with a 25-cm intra-abdominal mass and 6-cm ulcerated lesion at the top of the umbilicus. Laparotomy was performed which demonstrated a huge polycystic and solid tumour of the sigmoid mesentery infiltrating the sigmoid colon and appendix. Appendectomy and resection of the tumour with an infi ltrated sigmoid loop were performed. A right ovarian cyst – not contiguous to the aforementioned tumour – was found at the time of the operation and excised. We also removed the 6-cm skin lesion in the umbilical area.Histopathological examination revealed urothelial carcinoma with squamous cell metaplasia of the sigmoid mesocolon with bowel and umbilical invasion.Concurrent desmoid cyst (mature teratoma) of the right ovary was found.ConclusionsIn conclusion, this patient with a sigmoid mesocolon invasion from urothelial carcinoma of unknown origin posed a diagnostic dilemma

Individual and ethnic aspects of preoperative planning for posttraumatic rhinoplasty

The aim of this study was to compare the aesthetic results of post traumatic rhinoplasty among Europeans with populations of healthy Caucasians described in earlier reports, and to collate correct parameters of nasal shape in healthy representatives of both sexes and various races for improvement in aesthetic results of surgery. 3-D scanning of the face was performed in 54 patients after posttraumatic septorhinoplasty. Analysis of 3D model was based on two indices of the nasal proportions and four angles of the region from 18 anthropological points. Parameters of the nasal shape in addition to gender were compared to average values of healthy Caucasian population, described before. Normal characteristics of the nose among individuals of three races from previous studies were also compared to one another. In females, mean height and width of the nose as well as length of both nostrils was smaller. Neither were there any significant differences in width of the nostrils and length of the nasal pyramid nor nasal prominence. Nasal proportions were similar in both sexes. Some of the nasal angles differed in addition to gender. Posttraumatic rhinoplasty resulted in correct shape of the nose similar to the healthy Caucasian population. The aesthetic nose differ among healthy individuals of the three races analysed. While preoperative planning is important, knowledge of the normal values of parameters characterising shape in both genders is equally important as the individual differences in relation to the whole face
