Trichophytic granuloma of the vulva

[Trichophyton mentagrophytes genotype VII increasingly causes anogenital infections]

In the course of globalization, migration and global warming, we are increasingly confronted with pathogens that do not occur naturally in our latitudes or appear in a different form. We know keratinophilic dermatophytes as the cause of tinea pedis, onychomycosis and also tinea corporis and capitis. Transmission usually occurs via domestic or farm animals and via autoinoculation. In recent years dermatophytes have gained additional importance as a possible sexually transmitted disease between immunocompetent persons. For the first time, dermatophytosis was described as a sexually transmitted infection in travelers who developed pronounced pubogenital or anogenital tinea after travelling in Southeast Asia, including Thailand, mostly after intensive sexual contact. Molecular and cultural analyses have identified Trichophyton (T.) mentagrophytes ITS (internal transcribed spacer) genotype VII as the main pathogen. Although this dermatophyte genotypically belongs to the zoophilic complex, direct (sexual) and occasionally indirect human-to-human contact with infected persons is suspected to be the current route of transmission. The infection can lead to inflammatory and purulent dermatophytosis, causing a high level of suffering. In this respect, a rapid and reliable diagnosis is essential in order to be able to initiate targeted treatment. The discovery of infection pathways and the awareness of the need to take rare diseases into account in our everyday lives will increasingly accompany us over the next few years and present us with new challenges, particularly in terms of prevention and treatment.

Kerion of the pubis and vulva with bacterial superinfection: a rare occurrence

Kerion is a severe hypersensitivity reaction to fungal infection that is rarely seen in the groin. Frequent shaving of pubic hair and religious conservatism surrounding genital hygiene are common among Bedouin women in the Negev Desert, and may predispose to kerion. This case highlights the clinical course of a 20-year-old Bedouin woman who presented with severe kerion celsi of the pubis and vulva with secondary bacterial infection. The patient was successfully treated with intravenous antibiotics, oral antifungal medication and wet topical dressings. The case outlines the risk factors and treatment for severe kerion celsi of the groin, as well as possible preventive measures that may reduce its incidence.

Genital diseases in the mature woman

Vulvovaginal conditions are common in mature women. This reflects age-related changes in immunity and skin barrier function of vulvovaginal tissues. Vaginal atrophy is commonly complicated by dryness and inflammation, which makes postmenopausal atrophic vaginitis a virtually ubiquitous condition. The differential of vaginitis includes inflammatory, infectious, and malignant diseases, plus drug hypersensitivity. Atrophic vaginitis is treated with estrogen replacement therapy. Vulvovaginal malignant melanoma occurs predominantly in postmenopausal women and carries a poor prognosis. Similarly, the incidence of vulvovaginal malignancies, such as squamous cell carcinoma and extramammary Paget disease, rises exponentially after 65 years of age. Early diagnosis of these malignancies is of utmost importance. Lichen sclerosus et atrophicus and vulvovaginal candidosis are among the most common postmenopausal vulvovaginal conditions. Lichen sclerosus et atrophicus is associated with significant morbidity, and its management can be challenging. The incidence of vulvovaginal candidosis increases in patients on estrogen replacement therapy.

Skin diseases of the vulva: Infectious diseases

A multitude of infectious diseases of viral (genital herpes, herpes zoster, genital warts and molluscum contagiosum), bacterial (syphilis, chancroid, lymphogranuloma venereum, donovanosis, erysipelas, cellulitis and necrotising fasciitis, folliculitis, impetigo, bartholin gland abscess, trichomycosis and erythrasma), fungal (candidiasis and dermatophytosis) and parasitic (pediculosis pubis) origin may affect the vulvar area. Herein, we review the infections and their skin manifestations in the vulvar area.

Tinea profunda of the genital area. Successful treatment of a rare skin disease

We present a rare case of 36-year-old female patient, who developed a severe Majocchi granuloma in the pubis after waxing, with isolated causative agent Trichophyton mentagrophytes. The condition was initially misdiagnosed as a bacterial folliculitis and treated unsuccessfully with topical corticosteroids and antibiotics. After the adequate diagnose was confirmed by mycological examination, followed by histopathological verification, complete remission of the symptoms was achieved at the 4th week after initiating 6 weeks course of antifungal therapy with Terbinafine 250 mg/daily dose, while good therapeutic response was observed even in the 10th day. The etiopathogenesis of the disease, as well as its current treatment options are considered, in respect to the rare occurrence of this condition in the pubic area and its frequent misdiagnosis.

Tinea genitalis: a new entity of sexually transmitted infection? Case series and review of the literature

OBJECTIVE

Investigation on recent cases of tinea genitalis after travelling to South East Asia.

METHODS

Patients with tinea in the genital region, which emerged after sex in South East Asia, underwent further assessment including microscopy, cultures and DNA analyses.

RESULTS

The case series includes seven patients. In six patients, Trichophyton interdigitale (former Trichophyton mentagrophytes) was detected. Three patients suffered from a severe inflammatory reaction of the soft tissue and two of them needed hospitalisation due to severe pain. In four patients, cicatrising healing was noticed. Five patients were declared incapacitated for work.

CONCLUSIONS

Sexual activity should be considered as a potentially important and previously underappreciated means of transmission of T. interdigitale. To avoid irreversible scarring alopecia, prompt initiation of antifungal treatment is essential and adequate isolation and identification of the pathogen is mandatory.

Successful Treatment of Refractory Majocchi's Granuloma with Voriconazole and Review of Published Literature

Majocchi's granuloma (MG) is a rare deep skin dermatophyte infection that can occur either in immunocompetent or in immunocompromised individuals. Oral itraconazole or terbinafine is considered to be the first choice of treatment. We report an immunocompetent man with deep nodular form of MG, the form which is generally found in immunosuppressed individuals. Previous treatment with either oral itraconazole or terbinafine yielded no apparent improvement. After a series of examination, the man was diagnosed as having Trichophyton rubrum-induced MG mixed with bacterial infection as evidenced by growth of Klebsiella pneumoniae in tissue bacterial culture. The patient was treated with a combination of cefoselis and levofloxacin for bacterial clearance followed by voriconazole treatment. After approximately 4 months of voriconazole treatment, the lesions completely resolved. Alternative medicine (voriconazole) can be considered in case of refractory infections during MG treatment.

Kerion of the Vulva Caused by Trichophyton mentagrophytes

Background:

Deep dermatophytosis of genital skin is a rare clinical manifestation of infection by a common group of pathogens.

Objective:

We emphasize the importance of clinical suspicion and the use of accurate diagnostic methods in the evaluation of deep dermatophytosis.

Methods:

We report a single case of tinea pubis, kerion type, caused by Trichophyton mentagrophytes in an immunocompetent host.

Results:

A 54-year-old female presented with a suppurative infection of the vulva and pubis that was unresponsive to empirical antibiotic therapy. T. mentagrophytes was isolated. Oral itraconazole was initiated on the basis of clinical suspicion and continued for a total of 6 weeks.

Conclusion:

Accurate diagnosis and treatment of deep dermatophytosis of genital skin rests upon proper identification of the pathogen. Prompt initiation of treatment with an oral antifungal agent, such as itraconazole, should be undertaken in order to avoid irreversible scarring alopecia.
