Definition

Dermatophytosis

Dermatophytosis (ringworm or tinea) is an infection of the skin or skin derivatives, caused by fungi known as dermatophytes leading to erythema, small papules, plaques, vesicles, fissures, and scaling having ring-like morphology. Dermatophytes are filamentous fungi prone to invade and multiply in keratinised tissue, i.e. skin, hair and nails.

Naïve infection

A given subject is not previously exposed to a particular infection of a given disease or treatment for that disease.

Chronic Dermatophytosis

Dermatophytosis is considered to be chronic when the patients who have suffered from the disease for more than 6 months to 1 year, with or without recurrence, in spite of being adequately treated.

Recurrent Dermatophytosis

Dermatophytosis is considered to be recurrent when there is re-occurrence of the disease (lesions) within few weeks (<  6 weeks) after completion of the treatment.

Relapse

Relapse denotes the occurrence of dermatophytosis (lesions), after a longer period of infection-free interval (6–8 weeks) in a patient who has been cured clinically.

Trichophyton Rubrum Syndrome

Trichophyton Rubrum Syndrome is defined as,

(A) Skin lesions at the following four sites:

(1) Feet, often involving soles;

(2) Hands, often involving palms;

(3) Nails; and

(4) At least one lesion in another location other than (1) (2) or (3), except for the groin.

(B) Positive microscopic analyses of potassium hydroxide preparations of skin scrapings, in all four locations.

(C) Identification of Trichophyton rubrum by cell culture at three of the four locations at least.

For diagnosis of TRS, the criteria (A) and (B) and (C) have to be fulfilled.

BSA

The area of outstretched palm from the wrist to the tip of the fingers can be considered roughly 1% of the body surface area. Less than 3% can be counted mild, 3–10% as moderate, and more than 10% as severe, in terms of the extent of involvement.
