"Grille" is a term used in the Sepik region of Papua New Guinea to describe a skin condition also known as tinea imbricata. It's a type of ringworm, a fungal infection of the skin, characterized by its striking, filigree-like patterns. The distinctive appearance often leads to confusion with ritual scarification.
Understanding Tinea Imbricata ("Grille")
Tinea imbricata is a chronic fungal infection caused by dermatophytes, specifically Malassezia furfur and Trichophyton concentricum. The infection presents as expanding concentric rings of scales, creating a characteristic "grille" or "lace-like" pattern on the skin. It is particularly prevalent in tropical and subtropical regions.
Key Features of Tinea Imbricata:
- Appearance: Concentric, scaly rings resembling a filigree pattern. This is often mistaken for scarification.
- Location: Primarily affects the trunk and limbs.
- Symptoms: Itching is common, but severity can vary.
- Transmission: Spread through direct contact with infected individuals or contaminated objects.
Treatment of Tinea Imbricata
Treatment usually involves antifungal medications, both topical and systemic, depending on the severity of the infection. Early diagnosis and treatment are crucial to prevent the spread and long-term complications.
