ecthyma

Definition
Meaning
A specific type of ulcerative skin infection, deeper than impetigo, characterised by lesions with a thick, adherent crust, most commonly caused by Staphylococcus or Streptococcus bacteria.
In a broader or metaphorical context, 'ecthyma' can be used to describe any deep, crater-like ulceration or a persistent, festering problem, though such usage is extremely rare outside of medical literature.

FAQ
Frequently Asked Questions
Yes, the bacteria causing ecthyma (often Streptococcus or Staphylococcus) can be spread through direct contact with the infected skin or contaminated items.
Ecthyma penetrates deeper into the skin (the dermis), forming a distinct ulcer under a crust, whereas impetigo is a more superficial infection affecting only the epidermis.
It is more common in children, the elderly, and individuals with compromised immune systems, poor hygiene, or pre-existing skin conditions in warm, humid climates.
Yes, there is a specific, unrelated viral disease in sheep and goats called 'orf' or 'contagious ecthyma'. It's important to specify the species when using the term.
