Insights

Idiopathic plantar hidradenitis (IPH) presents as tender foot lesions in children. This condition shares histologic similarities with neutrophilic eccrine hidradenitis (NEH) but affects palms too.

Area of Science:

  • Dermatology
  • Pediatric Dermatology
  • Histopathology

Background:

  • Idiopathic plantar hidradenitis (IPH) is a recently identified condition.
  • It affects healthy children, causing painful lesions on the feet.
  • Histologic findings resemble neutrophilic eccrine hidradenitis (NEH).

Observation:

  • IPH lesions are typically localized to the plantar or lateral aspects of the feet.
  • Histology shows neutrophilic abscesses near eccrine coils, without syringosquamous metaplasia.
  • The clinical spectrum has expanded to include palmoplantar involvement.

Findings:

  • This report details an 8-year-old girl with palmoplantar nodules.
  • Literature review confirms IPH can affect both palms and soles.
  • The case expands the known clinical presentation of IPH.

Implications:

  • Understanding IPH's presentation is crucial for accurate diagnosis.
  • Recognizing palmoplantar involvement broadens the differential diagnosis for pediatric palmoplantar lesions.
  • Further research may clarify IPH's pathogenesis and optimal management.

Desmosomes

The term desmosome derives from the Greek words "desmo" and "soma" meaning "adhesion bodies." This structure was first observed during the late 1800s and described as small, dense nodules in the epidermis. Desmosomes are button-like structures that help form an interlinked network of intermediate filaments across the cells. These junctions are  essential to hold cells together under mechanical stress and to maintain tissue integrity. Desmosomes are multi-protein complexes comprising desmosomal...

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...
Acute Pancreatitis I: Introduction01:25

Acute Pancreatitis I: Introduction

Acute pancreatitis is the sudden inflammation of the pancreas caused by the early activation of digestive enzymes, leading to the autodigestion of pancreatic tissue. This results in local inflammation and, in severe cases, systemic complications.EtiologyUnderstanding the underlying causes is crucial, as identifying the etiology guides treatment and anticipates complications. Acute pancreatitis can be triggered by various factors, typically grouped into the following clinical categories.Biliary...
Acute Pancreatitis II: Pathophysiology01:21

Acute Pancreatitis II: Pathophysiology

The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...

Chronic Pancreatitis I: Introduction

Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...

Chronic Pancreatitis II: Pathophysiology

Chronic pancreatitis is a progressive and irreversible inflammation of the pancreas, most often caused by long-term alcohol abuse, but it can also be related to ductal obstruction, smoking, or genetic factors.Chronic pancreatitis occurs when the pancreas is repeatedly exposed to harmful agents like alcohol, smoking, ductal obstruction, or genetic predisposition. These factors lead to the release of toxic metabolites and inflammatory cytokines, sustaining chronic inflammation in the pancreatic...
