1. TINEA BARBAE
2. TINEA CORPORIS
3. TINEA CAPITIS
4. TINEA CRURIS ( JOCK ITCH)
5. TINEA PEDIS ( ATHLETE’S FOOT)
6. TINEA MANUUM
7. TINEA UNGUIUM

3. TINEA CAPITIS
This is the infection of the shaft or scalp hairs and presents as the
following clinical types:
a) Inflammatory:- Kerion,favus
b) Non-inflammatory :- Black dot, Ectothrix and Endothrix

4. The infection hairs in tinea capitis appear dull and grcy
The base of hair shaft as well as hair follicles in involved
These is breakage of hair at follicular which creates patches of
qlopecia with black dots of broken hairs
Hair infected can be diagnosed by using wood’s lamp ( yellow green
fluoresence)

6. TINEA CORPORIS
Characterised by erythematous scaly lesions, annular, sharply
marginated plaques with raised border which may be single, multiple
or confluent

8. TINEA PEDIS
This is the infection of planter aspects of foot , toes and interdigital
web spaces
It is frequently seen among individual wearing shoes for long hours
and populary known as Athlete’s foot
In toe webs,scaling, fissuring and erythema may be associated with
an itching or burning sensation

9. Due to muceration and peeling ,cracks appear which are prone to
secondary bacterial infections
When infection becomes chronic, sole becomes hyperkeratotic and
is often covered with fine scales

10. TINEA BARBAE

II. KOH wet mont:- Branching septate ( non-pigmented) hyphae is
considered positive for fungi, spores may also be seen
III. Wood’s lamp:- in suspected tinea capitis,plucked hair is examined
only using wood’s lamp.
- infected hair will be fluorescent ( Yellow green)

15. IV). Culture:- species identification is possible only by culture
examonation
- sabouraud’s dextrose agar

16. TREATMENT
