Vanishing enteric duplication cyst presenting with melaena.

A toddler presented with melaena on a background of a possible enteric duplication cyst, diagnosed in the neonatal period which 'vanished'. What was later confirmed to be a small bowel duplication cyst was not seen on follow-up ultrasounds and thus the patient was managed expectantly until presentation as an emergency. Our case highlights the challenges faced in managing cystic abdominal structures in infancy and the potential consequences of expectant management.

Comparative effectiveness of pathological techniques to improve lymph node yield from colorectal cancer specimens: a systematic review and network meta-analysis.

A number of randomised controlled trials (RCT) have compared different techniques to improve lymph node yield (LNY) in colorectal cancer specimens, but data on comparative effectiveness are sparse. Our aim was to compare the relative effectiveness and rank all available techniques. A systematic search of Embase, Cochrane, PubMed and Scopus was performed for randomised trials.

Granular cell tumour in a patient with Crohn's disease treated with infliximab: coincidence or causal relationship?

Granular cell tumour (or Abrikossoff's tumour) was first described by Abrikossoff in 1926. This is a rare benign neoplasm of unclear histogenesis that is generally believed to be of nerve sheath origin. Usually, it presents as a solitary lesion, located mainly in the subcutaneous tissue of the head, or the neck, or in the oral cavity, such as a tongue lesion, although it may develop anywhere in the body.

MR imaging findings of an atypical pulmonary hamartoma in a 12-year-old child.

We present the MR imaging findings in an atypical pulmonary hamartoma in a 12-year-old boy. CT showed no evidence of fat or calcifications in the tumour. It demonstrated peripheral rim enhancement on arterial-phase MR images due to a compressed respiratory epithelium, and progression to nearly homogeneous contrast enhancement on delayed-phase images.

Asymptomatic calcitonin-secreting tumor of the pancreas. A case report.

Context: Pancreatic endocrine tumors are unusual tumors arising from cells belonging generically to the amine precursor uptake and decarboxylation system.

Case Report: We present a case of a calcitonin-secreting pancreatic endocrine tumor in a 59-year-old male who presented at our Center with elevated calcitonin values. The patient was asymptomatic.
