Summary
This report details a rare case of scalp favus, a fungal infection, in a 60-year-old woman from a non-endemic region. The infection also affected her nails, caused by Trichophyton violaceum.
Area of Science:
- Dermatology
- Mycology
- Infectious Diseases
Background:
- Favus, a chronic fungal infection of the scalp, is characterized by scutula formation.
- While endemic in some regions, its occurrence in non-endemic areas is infrequent.
Purpose of the Study:
- To report a rare case of favus of the scalp and nails in a patient from a non-endemic zone.
- To highlight the etiological agent, Trichophyton violaceum, in this unusual presentation.
Main Methods:
- Clinical case presentation of a 60-year-old female with suspected favus.
- Microscopic examination of scalp and nail samples using Potassium Hydroxide (KOH) preparation.
- Fungal culture on Sabouraud's agar medium for species identification.
Main Results:
- KOH examination revealed fungal hyphae in both scalp and nail scrapings.
- Culture on Sabouraud's agar confirmed the presence of Trichophyton violaceum.
- The patient, residing in a non-endemic district of Rajasthan, presented with typical favus lesions on the scalp and nail involvement.
Conclusions:
- This case underscores the possibility of favus occurring outside its typical endemic zones.
- Trichophyton violaceum remains a significant etiological agent for favus, even in atypical geographical locations.
- Prompt diagnosis and treatment are crucial for managing favus, especially when it presents with unusual patterns or in non-endemic settings.

01:26Rocky 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.
01:28Infectious Diseases and Their Occurrence
Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable temporal or...
01:18Yellow Fever
Yellow fever is a viral hemorrhagic disease caused by the yellow fever virus (YFV), a member of the Flaviviridae family. It is transmitted primarily by Aedes and Haemagogus mosquitoes in tropical and subtropical regions of Africa and South America. After transmission through a mosquito bite, the virus initially replicates in skin-resident immune cells such as dendritic cells and macrophages. These cells then migrate to the lymph nodes, where viral replication increases, eventually leading to...
01:30Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...

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...
01:28Pulmonary Tuberculosis V
Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...
