Insights

Proteus mirabilis, a bacterium usually causing urinary tract infections, can rarely lead to facial infectious granuloma. This case highlights the uncommon presentation and diagnostic challenges of this rare facial infection.

Area of Science:

  • Microbiology
  • Infectious Diseases
  • Dermatology

Background:

  • Proteus mirabilis is a common cause of urinary tract infections.
  • Infections of the head and facial region by Proteus mirabilis are rare and clinically uncommon.
  • Distinguishing these infections from other facial diseases is challenging due to a lack of characteristic manifestations.

Purpose of the Study:

  • To report a rare case of facial infectious granuloma caused by Proteus mirabilis.
  • To enhance the understanding of Proteus mirabilis facial infections through clinical and literature review.

Main Methods:

  • Case report presentation.
  • Integration of clinical manifestations.
  • Postoperative follow-up and relevant literature review.

Main Results:

  • A patient presented with facial infectious granuloma.
  • The granuloma was confirmed to be caused by Proteus mirabilis infection.
  • The case underscores the rarity and diagnostic difficulty of such infections.

Conclusions:

  • Proteus mirabilis can cause rare facial infectious granulomas.
  • Early recognition and appropriate management are crucial for favorable outcomes.
  • Further research is needed to understand the pathogenesis and optimal treatment strategies for this rare condition.

Atypical Pneumonia01:14

Atypical Pneumonia

Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease...

Staphylococcal Skin Infections01:29

Staphylococcal Skin Infections

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Acne Infection01:27

Acne Infection

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

Microbiota of the Urogenital Tract01:28

Microbiota of the Urogenital Tract

The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...

Microbiota of the Respiratory Tract01:29

Microbiota of the Respiratory Tract

The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more...
