Correlation between Adenomyosis and Endometrial cancer: 6-year experience of a single center.

INTRODUCTION: Adenomyosis often co-exists in the pathological specimens after surgery for endometrial cancer. The aim of this study is to describe the clinicopathological and oncological characteristics of these patients and further investigate the possibility of malignant transformation in the adenomyotic tissue. METHODS: We retrospectively reviewed the medical records of all patients that underwent hysterectomy for endometrial cancer (January 2012 - December 2017). The pathological reports were studied and when adenomyosis was present, the pathological slides were reviewed in order to discover any malignant change in the adenomyotic tissue. The clinicopathological characteristics and oncological results were described. RESULTS: Out of 229 cases of endometrial cancer, 64 (28%) patients had concurrently endometrial cancer and adenomyosis. Among these 64 patients, 7 (11%) had malignant transformation of adenomyosis. The mean age of patients suffering from both endometrial cancer and adenomyosis was 63.2 years old and 57 (89%) of these patients, had early endometrial cancer. Concerning the patients with malignant transformation of adenomyosis, their mean age was 65 years old with no premenopausal case. DISCUSSION: Adenomyosis has been described in the last decades, but its malignant transformation into endometrial cancer is not fully undercovered. Further investigation is needed in order to clarify the pathologic progression of adenomyotic lesions to endometrial cancer.

Mid common bile duct inflammatory pseudotumor mimicking cholangiocarcinoma. A case report and literature review.

INTRODUCTION: Biliary inflammatory pseudotumors (IPTs) represent an exceptional benign cause of obstructive jaundice. These lesions are often mistaken for cholangiocarcinomas and are treated with major resections, because their final diagnosis can be achieved only after formal pathological examination of the resected specimen. Consequently, biliary IPTs are usually managed with unnecessary major resections. PRESENTATION OF CASE: A 71-year-old female patient underwent an extra-hepatic bile duct resection en-bloc with the gallbladder and regional lymph nodes for an obstructing intraluminal growing tumor of the mid common bile duct (CBD). Limited resection was decided intraoperatively because of negative for malignancy fast frozen sections analysis in addition to the benign macroscopic features of the lesion. Histologically the tumor proved an IPT, arising from the bile duct epithelium, composed of inflammatory cells and reactive mesenchymal tissues. DISCUSSION: The present case underlines the value of intraoperative reassessment of patients undergoing surgical resection for histopathologically undiagnosed biliary occupying lesions, in order to optimize their surgical management. CONCLUSION: The probability of benign lesions mimicking cholangiocarcinoma should always be considered to avoid unnecessary major surgical resections, especially in fragile and/or elderly patients.

Acute pancreatitis as the initial manifestation of an adenocarcinoma of the major duodenal papilla in a patient with familial adenomatous polyposis syndrome: a case report and literature review.

We report a case of an ampullary carcinoma presenting as acute pancreatitis in a patient with familial adenomatous polyposis (FAP) syndrome and severe duodenal adenomatosis. A 48-year-old woman was hospitalised because of an episode of acute pancreatitis. She had a history of prophylactic total colectomy for FAP 2 years earlier. On admission, abdominal ultrasonography and computed tomography revealed dilatation of the main pancreatic and common bile duct. Spigelman's stage IV duodenal adenomatosis involving the major duodenal papilla was diagnosed on endoscopy and a classical Whipple procedure was proposed. Pathologic examination of the duodenopancreatectomy specimen revealed a tubular adenocarcinoma of the papilla that occluded the major pancreatic ducts. The patient had no evidence of disease and experienced no recurrent attacks of acute pancreatitis during a 36-month period of follow-up.

Retroperitoneal extra-adrenal ganglioneuroma involving the infrahepatic inferior vena cava, celiac axis and superior mesenteric artery: A case report.

INTRODUCTION: Ganglioneuromas are rare benign neoplasms arising from the sympathetic neuroendocrine system. These tumors usually occur in the abdomen and tend to grow around major blood vessels making often their complete excision challenging and demanding. PRESENTATION OF CASE: The authors present the challenging surgical management of a sizable retroperitoneal extra-adrenal ganglioneuroma involving the infrahepatic inferior vena cava, portal triad, celiac axis and superior mesenteric artery in a 23-year-old female patient. The tumor was safely and completely excised in toto with preservation of all neighboring vital anatomical structures using a midi laparotomy access. DISCUSSION: Ganglioneuromas should be included in the differential diagnosis of any retroperitoneal mass. Their management involves total surgical excision however, in some instances; it can be challenging and demanding because of their tendency to engage neighboring vital anatomical structures. CONCLUSION: A surgical strategy including meticulous operative dissection guided by the quality principles of surgical oncology although challenging and demanding can result to a safe and complete tumor excision, which is directly correlated with an improved patients' postoperative outcome and excellent prognosis.

Primary ovarian small cell carcinoma of pulmonary type with enlarged paraaortic lymph node masses: a case report and review of the literature.

INTRODUCTION: Small cell carcinoma of the ovary of pulmonary type, is a rare, aggressive tumour with poor prognosis and its optimal management is unclear. CASE PRESENTATION: A 55-year-old Caucasian woman presented with abdominal discomfort and left lumbar pain within a three-week period. At exploratory laparotomy, a 8 cm solid cystic mass of the left ovary was found infiltrating the sigmoid colon, and a bulky mass (11 x 7 x 4 cm) in the left paraaortic infrarenal region. Histopathological features resembling small cell carcinoma of the lungs and positive immunohistochemical stains provided a definite diagnosis of IIIC ovarian small cell carcinoma of pulmonary type. After six cycles chemotherapy with carboplatin and etoposide, the patient is still alive at 21 months from initial diagnosis. DISCUSSION: In this case, the absence of peritoneal involvement and the extensive paraaortic adenopathy is suggestive of a different pattern of spread of this rare tumour. Optimal treatment seems to be radical primary debulking surgery resulting in no residual disease, maximizing the effect of adjuvant chemotherapy for this biological aggressive tumour.

Tuberculous orchitis US and MRI findings. Correlation with histopathological findings.

Tuberculosis of the testis is a rare disease. Although Ultrasound (US) findings of tuberculous epididymo-orchitis have been well described, there are only few reported cases describing the Magnetic Resonance Imaging (MR) findings of this disease. Herein, we describe the US and MR findings in a patient with tuberculous orchitis of the left testis and correlate them with the histopathological findings. In our case, the MR findings differ from previous studies because granulomatous areas in the testis had intermediate to high signal intensity on T2WI, while in all studies granulomatous areas in tuberculous epididymo-orchitis demonstrated invariably low signal intensity.
