A case of dermatophytic pseudomycetoma, in a patient with a history of recurrent lesions in the scalp, for over two years, is reported. Histopathological examination of the affected tissues revealed the mycelial aggregates or pseudogranules characteristic of the disease. Cultures of fresh tissues samples detected a fungus identified as Trichophyton tonsurans. Additional examinations failed to d...

Tinea capitis is the most common pediatric superficial dermatophyte infection. The causative species vary, as for instance, Microsporum canis predominates in Europe, while Trichophyton tonsurans predominates in North America. Tinea capitis does not respond well to topical therapy alone, thus oral therapy is requisite. The drug of choice is griseofulvin; however in some countries, it is no longe...

A series of hydrolysable tannins and related compounds was evaluated for antifungal activities against filamentous fungi (Epidermophyton floccosum; Microsporum canis; Microsporum gypseum; Trichophyton mentagrophytes; Trichophyton rubrum; Trichophyton tonsurans; Trichophyton terrestre; Penicillium italicum; Aspergillus fumigatus; Mucor racemosus; Rhizopus nigricans) and opportunistic yeasts (Can...

Synthetic hair implants are considered in alopecia when the patient requests an immediate result with minor surgery and with a poor donor area. However, the procedure has historically been marred by poor quality fiber and performance resulting in serious complications. Nevertheless, companies continue to market the procedure with the claim that previous problems have been sorted out. We report ...

The antimycotic effect of Casia alata (Linn.) commonly used for the treatment skin diseases by local people in Nigeria was evaluated against dermatophytes (Trichophyton tonsurans, Trichophyton rubrum, mentagrophytes, Microsporum audouinii, canis, gypseum, Epidermophyton floccosum). Ten-fold serially diluted extract concentrations were subjected to phytochemical screening and activity phytochemi...

Background: Trichophyton tonsurans is one of the dermatophyte fungi which invades the skin and hair of human. Several properties of this fungus have been investigated so far. However a few studies were carried out in the field of molecular biology of this fungus. In the present study, we tried to identify the Squalene epoxidase gene which is related to synthesis of ergosterol in this fungus. Me...

BACKGROUND Diabetic patients are particularly susceptible to fungal infections due to modifications that occur in their immunological system. These modifications compromise natural defences, such as skin and nails, especially from lower limbs. AIMS Assessing the presence of dermatomycosis in lower limbs of Portuguese diabetic patients followed on Podiatry consultation. Determination of possib...
