Pancreatic Intraductal Papillary Mucinous Neoplasm Associated Colloid Carcinoma

Colloid carcinomas are rare pancreatic tumors characterized by the presence of mucin pools with scarce malignant cells. Most of these neoplasms arise from intestinal-type intraductal papillary mucinous neoplasms (IPMNs). We report a case of a 77-year-old male patient who presented with weight loss, asthenia, lumbar pain and diabetes. Imaging studies revealed a mixed-type IPMN with high-risk features and a possi...

Susceptibility Perturbation MRI Maps Tumor Infiltration into Mesorectal Lymph N...

Noninvasive characterization of lymph node involvement in cancer is an enduring onerous challenge. In rectal cancer, pathologic lymph node status constitutes the most important determinant of local recurrence and overall survival, and patients with involved lymph nodes may benefit from preoperative chemo and/or radiotherapy. However, knowledge of lymph node status before surgery is currently hampered by limited...

An ontogenetic approach to gynecologic malignancies

Ontogenetic anatomy is the mapping of body compartments established during early embryologic development, particularly well demarcated in the adult pelvis. Traditional cancer surgery is based on wide tumour excision with a safe margin, whereas the ontogenetic theory of local tumour spread claims that local dissemination is facilitated in the ontogenetic compartment of origin, but suppressed at its borders in th...

High-risk features in potentially resectable colon cancer: a prospective MDCT-p...

Neoadjuvant chemotherapy in potentially resectable high-risk Stage II and Stage III colon cancer has demonstrated promising results in the PRODIGE 22-ECKINOXE Phase II trial. Identification of adverse morphologic features, namely T3 with >5 mm extramural extension/T4 stages and/or N2, is fundamental and requires accurate noninvasive imaging. Our aim was to assess the value of optimized preoperative MDCT to stra...

Isolated Visceral Angioedema Induced by Angiotensin-Converting Enzyme Inhibitor

Visceral angioedema is a rare complication of therapy with angiotensin-converting enzyme (ACE) inhibitors. Clinical presentation includes nausea, vomiting, abdominal pain and diarrhea. Early detection of this entity can prevent recurrent episodes and unnecessary invasive procedures, including surgery. This article describes a 46-year-old-woman who presented to the emergency department with abdominal pain, assoc...

Duodeno-colic fistula as a rare presentation of lung cancer - surgical treatmen...

INTRODUCTION: Rare adenosquamous carcinomas have no defined standard approach given their low incidence. They present with nonspecific imaging characteristics and are described as having worse prognosis than other lung malignancies, with greater likelihood of local invasion and early metastasis. PRESENTATION OF CASE: Male caucasian patient, 43 years, 26 pack-year smoking history, presented with watery diarrhea,...

Selection of colon cancer patients for neoadjuvant chemotherapy based on optimi...

PURPOSE: Neoadjuvant chemotherapy (NACT) in potencially-resectable locally advanced colon cancer (LACC) is likely to prove superiority compared to standard treatment in the phase III FOXTROT Collaborative Group Trial. Thus, identification of LACC, defined as T3≥5 mm or T4, is fundamental and requires accurate noninvasive imaging. The value of optimized preoperative MDCT for that purpose is being assessed. METHO...

Pancreatite da goteira duodenopancreática

INTRODUÇÃO: A pancreatite da goteira duodenopancreática é uma forma rara de pancreatite que afecta a goteira entre a cabeça do pâncreas, o duodeno e a via biliar principal. Manifesta-se por dor abdominal, vómitos e icterícia. O tratamento inclui pausa alimentar, analgesia e colocação de próteses endoscópicas. A cirurgia está indicada na doença refractária ou na suspeita de carcinoma da cabeça do pâncreas. MATER...
