    Study Notes

    Fungal Infections

    • Fungal infections are common, affecting 20-25% of the world population.
    • Predisposing factors include tropical climates, manual labor, low socioeconomic status, profuse sweating, friction with clothes, malnutrition, and immunosuppression.
    • Fungal infections can be classified as superficial or deep.

    Superficial Infections

    • Superficial fungal infections are caused by dermatophytes, specifically Microsporum, Trichophyton, and Epidermophyton.
    • Superficial fungal infections can affect different parts of the body:
      • Tinea Capitis (Scalp Ringworm): Invasion of the hair shaft by dermatophytes, mainly seen in children.
        • There are 4 varieties:
          • Gray Patch (Ectothrix): non-inflammatory, caused by Microsporum spp, characterized by patches of partial hair loss with dull, grey, easily pluckable hairs.
          • Black Dot (Endothrix): characterized by brittle hair shafts, broken-off hairs with black dots, minimal inflammation, and green fluorescence under Wood's Lamp examination.
          • Kerion: inflammatory, painful, boggy swelling with purulent discharge, vesicles, pustules, thick crusting, matting of hair, lymphadenopathy, secondary bacterial infection, and scarring.
          • Favus: inflammatory, begins early in life, characterized by yellow, cup-shaped crusts (scutula), mousy odor, matted hair, and extensive patchy hair loss with cicatricial alopecia.
      • Tinea Barbae (Barber's Itch): Ringworm of the beard and moustache area, mainly affecting adult males.

    • Partial hair loss is common across all types.
    • There are four varieties of Tinea Capitis:
      • Gray Patch (Ectothrix): Non-inflammatory type caused by Microsporum species, characterized by patches of partial hair loss and easily pluckable, dull grey hairs.
      • Black Dot (Endothrix): Endothrix organisms cause brittle hair shafts, leading to black dots from broken off hairs. Inflammation is minimal, and a Wood's Lamp examination will reveal green fluorescence.
      • Kerion: Inflammatory type with painful, boggy swelling, purulent discharge, vesicles, pustules, thick crusting, matted hair, lymphadenopathy, and secondary bacterial infection. Heals with scarring.
      • Favus: Inflammatory type that begins early in life. Characterized by yellow, cup-shaped crusts (scutula), mousy odor, matted hair, and extensive patchy hair loss with cicatricial alopecia.

    Tinea Barbae (Barber's Itch)
