Description

Obsolete Trichophyton verrucosum Tinea Capitis

Trichophyton verrucosum was a type of dermatophyte mold that caused a fungal infection of the scalp and hair, known as tinea capitis. This condition primarily affected children and was characterized by an ectothrix infectious disease.

Key Features:

  • Age Group: Children were most commonly affected by this condition.
  • Type of Infection: Ectothrix infectious disease caused by Trichophyton verrucosum dermatophyte mold.
  • Symptoms: Mild scaling lesions to widespread alopecia (hair loss).

According to search results [5], Trichophyton verrucosum tinea capitis was an obsolete form of the condition, suggesting that it is no longer a common or relevant concern in modern times.

Signs and Symptoms

Symptoms of Tinea Capitis

Tinea capitis, also known as scalp ringworm, is a fungal infection that affects the hair follicles on the scalp. The symptoms of this condition can vary from mild to severe and include:

  • Hair loss (alopecia) [7]
  • Dry scaly areas on the scalp [1]
  • Redness and inflammation [3][8]
  • Itching and irritation [6]

In some cases, tinea capitis can progress to more severe symptoms, such as:

  • Crusting and swelling of the scalp [5]
  • Large inflammatory and pustular plaques with extensive alopecia [3]
  • Abscesses (kerions) caused by a fungal infection [5]

Anthropophilic and Zoophilic Tinea Capitis

There are two types of tinea capitis: anthropophilic and zoophilic. Anthropophilic tinea capitis is characterized by non-inflammatory, grayish patches of hair and may be spread by contact with infected headgear [4]. Zoophilic tinea capitis, on the other hand, is caused by a fungal infection that affects animals and can be transmitted to humans through contact with infected animals or their products.

Additional Symptoms

  • dry scaly areas on the scalp
  • crusting and swelling of the scalp
  • large inflammatory and pustular plaques with extensive alopecia
  • abscesses (kerions) caused by a fungal infection
  • hair loss
  • inflammation
  • itching

Diagnostic Tests

Based on the search results, it appears that there are various diagnostic tests for tinea capitis, including:

  • Fungal culture [11]
  • Dermoscopy [12]
  • Molecular techniques [12]
  • Filtered ultraviolet light examination (Wood's light) [13]

However, it seems that Trichophyton verrucosum is an obsolete species. The search results mention that the diagnosis of tinea capitis is facilitated by filtered ultraviolet light examination (Wood's light), but only Microsporum species fluoresce under

Treatment

Treatment Options for Obsolete Trichophyton verrucosum Tinea Capitis

Tinea capitis, also known as ringworm of the scalp, is a fungal infection caused by Trichophyton verrucosum. While this condition has largely been eradicated in many parts of the world due to improved hygiene and antifungal treatments, there are still some areas where it persists.

Historical Treatment Options

In the past, griseofulvin was the most widely used medication to treat tinea capitis [5]. However, with the advent of newer antifungal agents, other treatment options have become available. These include:

  • Itraconazole: This oral antifungal agent has been reported to be effective in treating Trichophyton infections, including tinea capitis [2].
  • Terbinafine: Another oral antifungal medication, terbinafine has also been shown to be effective against Trichophyton species [2].
  • Fluconazole: This triazole antifungal agent is another option for treating tinea capitis caused by Trichophyton verrucosum.

Recommended Treatment Duration

The duration of treatment should be between 4 and 6 weeks, as recommended by some studies [1].

Availability of Medications

It's worth noting that griseofulvin is no longer available in some countries, including New Zealand [7]. In such cases, alternative treatments like itraconazole or terbinafine may need to be

Differential Diagnosis

The differential diagnosis for obsolete Trichophyton verrucosum tinea capitis, a type of fungal infection that affects the scalp, includes several conditions that can cause similar symptoms. According to various medical sources [4][8], these conditions include:

  • Seborrheic dermatitis: a chronic inflammatory skin condition characterized by flaky, itchy patches on the scalp [5].
  • Psoriasis: an autoimmune condition that causes red, scaly patches on the scalp and other areas of the body [10].
  • Eczema: a type of inflammation that can cause dry, itchy patches on the scalp and other parts of the body [5].
  • Tinea amiantacea: a rare form of fungal infection that affects the hair shafts and causes them to become brittle and break off [5].

It's worth noting that Trichophyton verrucosum is an obsolete cause of tinea capitis, meaning it is no longer considered a primary cause of this condition. However, the differential diagnosis for tinea capitis still includes these conditions, as they can present with similar symptoms.

In terms of specific characteristics, Trichophyton verrucosum tinea capitis was previously known to be caused by the fungus Microsporum [8]. However, it's now considered obsolete and is no longer a primary concern in medical diagnosis.
