Appendicitis

Appendicitis

Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...

Diverticular Disease of the Colon

Diverticular Disease of the Colon

Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...

Chronic Pancreatitis I: Introduction

Chronic Pancreatitis I: Introduction

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Summary

Solid pseudopapillary tumours (SPTs) are rare pancreatic neoplasms. This study reports a unique case of an SPT occurring in the transverse mesocolon without heterotopic pancreatic tissue in an adolescent female.

Area of Science:

Gastroenterology
Surgical Pathology
Oncology

Background:

Solid pseudopapillary tumours (SPTs) are rare neoplasms typically originating in the pancreas.
Extrapancreatic SPTs are exceptionally uncommon and often associated with heterotopic pancreatic tissue.

Observation:

This report details an unusual case of an 18-year-old female patient.
The patient presented with a solid pseudopapillary tumour arising from the transverse mesocolon.

Findings:

The tumour was located in the transverse mesocolon, a site rarely associated with SPTs.
Crucially, no evidence of heterotopic pancreatic tissue was found in the vicinity of the tumour.

Implications:

This case expands the known anatomical locations for solid pseudopapillary tumours.
It highlights the possibility of SPTs developing in extranatomic sites without the presence of heterotopic pancreatic tissue.
Further research may be warranted to understand the pathogenesis of such extrapancreatic SPTs.
