Rheumatic Heart Disease I: Introduction01:23

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
Rocky Mountain Spotted Fever01:26

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.

Area of Science:

  • Dermatology
  • Histopathology

Background:

  • Rosacea is a common facial skin condition with four recognized clinical subtypes.
  • A granulomatous variant is acknowledged within the broader rosacea spectrum.

Purpose of the Study:

  • To investigate the histopathologic patterns and cellular makeup of granulomatous rosacea.
  • To correlate these microscopic findings with the clinical presentation of affected patients.

Main Methods:

  • Review of facial biopsies from patients with a clinical diagnosis of rosacea and confirmed granulomatous infiltrate.
  • Correlation of histopathologic patterns with clinical observations.

Main Results:

  • Four distinct histopathologic granulomatous patterns were identified: nodular, perifollicular, diffuse, and combined.
  • Significant variation in clinical presentation was observed among patients.
  • No clear correlation was found between specific histopathologic patterns and clinical features.

Conclusions:

  • Granulomatous rosacea exhibits diverse histopathologic presentations.
  • The lack of clinical correlation suggests granulomatous rosacea may be a distinct histological variant rather than a specific subtype.
  • This histological variant can manifest across the spectrum of rosacea clinical types.
