Summary
Tinea incognito, a fungal infection exacerbated by topical corticosteroids, presents as worsening skin lesions. This case highlights how improper steroid use can transform a simple fungal infection into a disseminated inflammatory condition.
Area of Science:
- Dermatology
- Mycology
- Infectious Diseases
Context:
- Tinea incognito is a clinical presentation of superficial fungal infections.
- It arises from the inappropriate use of topical corticosteroids, which suppress the host's immune response.
- This can lead to atypical clinical features and spread of the infection.
Purpose:
- To report a case of disseminated inflammatory tinea incognito.
- To illustrate the clinical evolution and diagnostic confirmation of this condition.
- To discuss factors contributing to the dissemination of fungal infections under corticosteroid therapy.
Summary:
- A 71-year-old male presented with widespread erythematous and squamous lesions.
- Lesions worsened over seven months of topical corticosteroid treatment, with new pustular formations appearing.
- Diagnosis of disseminated inflammatory tinea was confirmed by fungal culture, identifying Trichophyton mentagrophytes.
Impact:
- This case underscores the potential for topical corticosteroids to mask and exacerbate fungal infections.
- It emphasizes the importance of considering tinea incognito in patients with worsening dermatoses under steroid treatment.
- Understanding these factors is crucial for accurate diagnosis and effective management of fungal infections.

01:31Pulmonary Tuberculosis III
Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

01:25Endocarditis II: Clinical Features of Infective Endocarditis
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...
01:23Skin 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...

01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
01:26Pulmonary Tuberculosis IV
Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

01:20Candidiasis
Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
