Skin Diseases and Disorders01:23

Skin Diseases and Disorders

5.1K
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...

Staphylococcal Skin Infections01:29

Staphylococcal Skin Infections

138
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...

Endocarditis II: Clinical Features of Infective Endocarditis

919
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Fungal Phylum Basidiomycota01:26

Fungal Phylum Basidiomycota

2.1K
Basidiomycota is a diverse phylum of fungi that includes ecologically significant decomposers such as white rot fungi, symbionts like mycorrhizal fungi, plant pathogens such as rusts and smuts, and edible species like Agaricus bisporus (the common button mushroom). These fungi play crucial roles in nutrient cycling, symbiotic relationships, and even human health. Their defining feature is the basidium, a microscopic club-shaped structure responsible for producing basidiospores.Fruiting Bodies...

Fungal Phylum Microsporidia01:28

Fungal Phylum Microsporidia

778
Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

896
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Area of Science:

  • Mycology
  • Infectious Diseases
  • Dermatology

Background:

  • Phaeohyphomycosis encompasses infections caused by dematiaceous fungi.
  • These infections can present with diverse clinical manifestations.

Purpose of the Study:

  • To report a rare case of subcutaneous phaeohyphomycosis.
  • To highlight the diagnostic challenges and histopathological findings.

Main Methods:

  • A case of a 57-year-old male with uncontrolled type 2 diabetes mellitus was analyzed.
  • Clinical presentation involved a posterior left elbow swelling.
  • Surgical excision of the lesion was performed for diagnosis.

Main Results:

  • Histopathological examination revealed a fungal abscess.
  • The findings were consistent with subcutaneous phaeohyphomycosis.
  • The initial provisional diagnosis was tuberculous bursitis.

Conclusions:

  • Subcutaneous phaeohyphomycosis can mimic other conditions like tuberculous bursitis.
  • Prompt histopathological examination is crucial for accurate diagnosis.
  • Diabetes mellitus may be a predisposing factor for such infections.
