ABSTRACT
Non-sebaceous lymphadenoma of the salivary glands is a rare benign lesion, first described in 1991. We present the case of a 54-year-old woman, with a right parotid mass. She underwent right superficial parotidectomy, and histopathology reported a non-sebaceous lymphadenoma due to an encapsulated lesion and multiple non-atypical epithelial inclusions without sebaceous differentiation. The etiology of non-sebaceous lymphadenoma is not yet understood, but it can arise predominantly from the parotid gland. Surgical excision is the treatment of choice.
ABSTRACT
INTRODUCTION: Distal Intestinal Obstruction Syndrome is a rare complication in patients with cystic fibrosis, which characterized by the accumulation of viscid fecal material, combined with sticky mucous secretions located in the distal ileum adhere to the intestinal wall, causing complete bowel obstruction. PRESENTATION OF CASE: We report a case of a 45 years old patient with cystic fibrosis, who presented bowel obstruction secondary to accumulation of fecal material, combined with mucous secretions, in the mid-jejunum. A diagnostic laparoscopy was performed where a dilated jejunum was encountered with impaction of fecal content. Surgery was converted to open surgery, where a longitudinal enterotomy of 5 cm after the transition zone was created, evacuating manually the fecal material with mucous secretion. The patient evolved favorably, without complications. DISCUSSION: We present a case of a patient with cystic fibrosis presenting with bowel obstruction due to a proximal intestinal obstruction syndrome, which can be diagnosed with the DIOS definition, with the only distinction of a more proximal location in the gastrointestinal tract, such as the stomach, the duodenum, or the jejunum. CONCLUSION: It is important for the clinician to know the existence of this syndrome at its different locations in the small bowel to treat accordingly.

BACKGROUND: Pancreatic macrocystic serous cystadenoma is an uncommon benign lesion that can be misdiagnosed as a mucinous cystic neoplasm which, in turn, harbors malignant potential. We present the case of a patient with a pancreatic macrocystic serous cystadenoma and review current diagnostic modalities. CLINICAL CASE: We present the case of a 28-year-old otherwise-healthy female who was incidentally found to have a pancreatic cyst. Computed tomography (CT) and endoscopic ultrasound (EUS) revealed a 3.0 cm lobulated and septated lesion in the head of the pancreas. Fine-needle aspiration (FNA) of the cyst revealed mucoid contents and a carcinoembryonic antigen (CEA) level of 0.69 ng/mL. The presumptive diagnosis of a mucinous cystic neoplasm was made and the lesion was resected by enucleation. Surgical pathology reported a 1.60 cm dominant cystic lesion lined with cuboidal epithelium and multiple adjacent microscopic satellite cysts, consistent with the macrocystic variant of the serous cystadenoma. CONCLUSIONS: Pancreatic macrocystic serous cystadenoma is uncommon and can be misdiagnosed as a mucinous cystic neoplas. In order to make an accurate diagnosis and to select appropriate treatment, surgeons must be familiar with the current diagnostic modalities.
