CASE PRESENTATION - A Case of Extensive Tinea
36 yr female presented with well defined annular hyperpigmented scaly plaques over face,neck,trunk with involvement of both upper and lower limbs since 8 months
H/o partial clearance of lesions with flucanazole 150mg earlier for 8 weeks
No systemic signs of illness
Clinical improvement with oral Itraconazole 100mg twicw daily for a month
KOH examination revealed numerous hyphae
Culture-Positive for Trichophyton rubrum
Local impaired immune responses in some parts of the skin may explain the extensive dermatophyte infection in patients with normal immune status.
The great variations in clinical presentations are related to the species and strains of the fungus, the size of the inoculum, the body area, and the immune status of the host
Suman et al revealed T. rubrum is the main dermatophyte reported from India causing tinea corporis.
Lack of delayed hypersensitivity reaction in presence of a positive immediate hypersensitivity (IH) response to trichophytin antigen points toward the chronicity of disease
Current clinical scenario reveals there is an increasing recognition of a rising trend of nonresponsive cutaneous dermatophytosis.
