Dermatofibrosarcoma protuberans: a case report and review of the literature.

BACKGROUND: Dermatofibrosarcoma protuberans (DFSP) represents less than 0.1% of all tumors, but it is considered the most common skin sarcoma. Wide local excision (=5 cm) has been largely replaced by Mohs micrographic surgery; however, recurrence is not rare. Description of the case: A 35-year-old man presented with a large tumor on the upper side of his back and underwent local excision with the possible preoperative diagnosis of lipoma. Upon histological examination, the diagnosis of DFSP was made, and the patient underwent wide local excision with skin flap reconstruction and was referred for adjuvant radiotherapy.On twenty months follow-up, no recurrence has been observed. CONCLUSION: DFSP is the most common cutaneous sarcoma. It originates in the dermis and tends to infiltrate underlying structures, including muscles, tendons, fascia and bone. In our case, the tumor was confined to the skin and subcutaneous tissue, however, our patient underwent adjuvant radiotherapy to avoid a possible relapse that would infiltrate deeper structures. Long-term follow-up is strongly recommended. Hippokratia 2016, 20(1): 80-83.

A retrospective analysis of 2000 cases with colorectal carcinoma.

PURPOSE: Colorectal cancer (CRC) is a major cause of death in the western world and a leading cause of cancer-related death. It is one of the most common human malignancies with >300,000 cases both in the United States and in the European Union each year. The present study was conducted to assess differences in various variables of CRC, such as location of the tumor, differentiation, Dukes classification, 5-year survival and possible changes in these patterns during the examined period. METHODS: We collected data on 2000 patients with colorectal cancer, diagnosed and treated from 1960 to 2008 in 1st Propedeutic Surgical Clinic of Aristotle's University, Thessaloniki. RESULTS: Of 2000 cases reviewed, cancer was almost equal presented to both sexes, for all groups. Rectum was the most common tumor location in all analyzed groups (40.1%). The most common tumor differentiation was the moderate one (68.5%). Concerning tumor staging, Dukes' B tumors were most common (42.5%), and the cancer-related 5-year survival was increased by the time from 42 to 71%. CONCLUSION: In the past 20 years, considerable improvements have been made in colorectal cancer therapy, and patients had received more sophisticated and multidisciplinary treatments, resulting in a better 5-year survival rate.

Rectal endometriosis: a case report.

We present the case of a 45-year-old female patient who was admitted with a history of pelvic pain, constipation, and dysmenorrhea. CT scan and u/s images revealed cholelithiasis, benign nodular hyperplasia of segment IV of the liver and uterine fibromyoma. During laparotomy, firm adhesions between the posterior wall of the uterus and the rectum were found and the incisional biopsy reveals an undifferentiated adenocarcinoma. Then, total resection of the uterus was performed with en block resection of the adherent part of the rectum and part of the posterior wall of the vagina. The final histopathological report showed the presence of uterine fibromyoma, nodular hyperplasia of the liver and rectal endometriosis without any sign of malignancy. The patient after 5 years of follow up remains healthy. Rectal endometriosis represents an uncommon localization of pelvic endometriosis where the symptoms and clinical findings are non-specific making the definitive preoperative diagnosis difficult. Endometriosis should be included in the differential diagnosis of chronic pelvic pain in combination with defecation disorders in female patients of reproductive age.

Gossypiboma presenting as mesosigmoid abscess [corrected].

INTRODUCTION: The term "gossypiboma" is used to describe any mass of non-absorbable surgical material. It is estimated that this complication appears every 1.000-10.000 procedures. It may lead to peritonitis, acute abdominal pain, intraperitoneal abscess, bowel obstruction, or perforation. REPORT OF A CASE: We present the case of an 80-year-old female patient admitted for chronic abdominal pain and fever. A CT scan and MRI were performed with a probable diagnosis of carcinoma or pelvic abscess. A surgical history of hysterectomy and repair of abdominal wall hernia with a mesh were mentioned. RESULTS: Exploratory laparotomy revealed the presence of an irregular, soft mass with characteristics of an abscess located into the mesosigmoid. Hartman's sigmoidectomy was performed, and the patient's postoperative course was uneventful. The histopathological examination confirmed the diagnosis of gossypiboma. CONCLUSIONS: Retained foreign intraperitoneal materials often represent diagnostic dilemmas, since symptomatology is no specific and the time elapsed from surgery is long. The policy of prevention's importance is highly appreciated.

Inflammation of solitary caecal diverticula:a rare aetiology of acute abdominal pain [corrected].

Caecal diverticula are rare, representing the 3.6% of colonic diverticula. They may have congenital origin and remain asymptomatic, presenting as an accidental finding. We present a case of a 42-year-old Caucasian woman, admitted with a 12-h history of sudden onset of sharp right iliac fossa pain, anorexia, and nausea. There was leukocytosis (23.49 × 10(3)/µl) and increased C-reactive protein (11.76 mg/dl). CT scan showed an inflamed appendix. At laparotomy, a diffuse caecal phlegmon with an inflammatory solitary caecal diverticula was found. A limited right hemicolectomy was performed. Histological examination confirmed the caecal diverticulitis without malignancy. Post-operative period was uneventful. Three months later, endoscopy showed no diverticula or other pathologies. Solitary caecal diverticulum is very rare, but surgeons must bear this in mind in case of pain in right iliac fossa.

Prospective clinical trial comparing sphincterotomy, nitroglycerin ointment and xylocaine/lactulose combination for the treatment of anal fissure.

BACKGROUND: The aim of this study is to compare the ability of three treatments in patients with anal fissure, sphincterotomy, nitroglycerin ointment and combination of gel xylocaine and lactulose. METHODS: Ninety adults divided in three groups of 30 patients each group, received one of the three treatments in a 3-year interval (2007-2009) and the follow-up was for 2 months. Group A received nitroglycerin ointment, Group B underwent sphincterotomy and Group C received gel xylocaine and lactulose. RESULTS: Concerning pain, after treatment 60% of patients in Group A did not complain of pain, 20% had transient pain, another 10% moderate pain and the remaining 10% had severe pain. In Group B, 95% of the patients had no pain and only 5% had mild, transient pain. In Group C 60% of the patients had moderate pain and the other 40% suffered from severe pain. Concerning fissure healing, in 60% of the patients of Group A, the fissure was healed. In Group B fissure healed in 93.3% and in Group C only in 16.6% of the patients. CONCLUSION: The "gold standard" for anal fissure treatment is the lateral internal sphincterotomy and that each one of the three methods has its advantages and disadvantages.
