*Less common than [[Superficial Pyoderma|superficial pyoderma]]
*Occurs mainly in dogs
*Affects infundibulum, isthmic portion of hair follicles and surrounding dermis and subcutis
*Heals with scarring
*Local lymph nodes are often affected
*Often secondary to immunosuppression, follicular hyperkeratosis or [[Parasitic skin infections - Pathology#Demodicosis|demodicosis]]
*May also be a sequele to [[Bacterial skin infections - Pathology#Superficial pyoderma|superficial pyoderma]]
*Grossly:
**[[Skin Glossary - Pathology|Crusted papules, pustules, alopecia, abscesses, nodules, fistulas, ulcers, haemorrhagic bullae]]
**In dogs may look similar to [[Pyotraumatic Dermatitis|pyotraumatic dermatitis]]
*Microscopically:
**Pyogranulomatous folliculitis and furunculosis
**Nodular or diffuse dermatitis
**Panniculitis
*May involve a foreign bodey reaction to follicular contents and draining sinuses develop
*If chronic, scarring and loss of adnexa
*Bacteria often isolated include [[:Category:Staphylococcus species|''Staphylococcus'' spp.]], especially ''S. intermedius'' in dogs, [[:Category:Streptococcus species|''Streptococcus'' spp.]], ''[[Corynebacterium pseudotuberculosis]]'', [[:Category:Pseudomonas and Burkholderia species|''Pseudomonas'']], [[:Category:Pasteurella and Mannheimia species|''Pasteurella'']], [[Proteus|''Proteus'']], [[Escherichia coli|''E.coli'']]
====[[Staphylococcal Folliculitis and Furunculosis]]====
====[[Subcutaneous Abscesses]]====
*Purulent exudate within dermis and subcutis
*Commonly occurs in cats due to contamination of penetrating wounds
*Surrounding wall of collagen and fibroblasts may develop
*Common bacteria (often normal mouth flora)
