Hyperinflammatory proliferative (blastomycosis-like) pyodermas: review, mechanisms, and therapy. 1986

O J Stone

Some sites of chronic localized infection have a vigorous granulocytic inflammatory response and develop marked tissue proliferation. This is most common in patients with poor nutrition, halogen ingestion or foreign bodies. The granulocytes release connective tissue-activating peptides which cause fibroblast proliferation and ground substance formation. The dermal papillae enlarge and support a larger germinative cell volume, producing pseudoepitheliomatous hyperplasia. Hypertrophic granulation tissue or "proud flesh" appears to be a similar phenomenon without the epithelial component. In a milder physiologic range this phenomenon probably accounts for the term "laudable pus."

UI	MeSH Term	Description	Entries
D007249	Inflammation	A pathological process characterized by injury or destruction of tissues caused by a variety of cytologic and chemical reactions. It is usually manifested by typical signs of pain, heat, redness, swelling, and loss of function.

D011711	Pyoderma	Any purulent skin disease (Dorland, 27th ed).	Pyodermas
D001759	Blastomycosis	A fungal infection that may appear in two forms: 1, a primary lesion characterized by the formation of a small cutaneous nodule and small nodules along the lymphatics that may heal within several months; and 2, chronic granulomatous lesions characterized by thick crusts, warty growths, and unusual vascularity and infection in the middle or upper lobes of the lung.

D003475	Curettage	A scraping, usually of the interior of a cavity or tract, for removal of new growth or other abnormal tissue, or to obtain material for tissue diagnosis. It is performed with a curet (curette), a spoon-shaped instrument designed for that purpose. (From Stedman, 25th ed & Dorland, 27th ed)	Curettages
D003646	Debridement	The removal of foreign material and devitalized or contaminated tissue from or adjacent to a traumatic or infected lesion until surrounding healthy tissue is exposed. (Dorland, 27th ed)	Debridements
D005347	Fibroblasts	Connective tissue cells which secrete an extracellular matrix rich in collagen and other macromolecules.	Fibroblast
D006025	Glycosaminoglycans	Heteropolysaccharides which contain an N-acetylated hexosamine in a characteristic repeating disaccharide unit. The repeating structure of each disaccharide involves alternate 1,4- and 1,3-linkages consisting of either N-acetylglucosamine (see ACETYLGLUCOSAMINE) or N-acetylgalactosamine (see ACETYLGALACTOSAMINE).

D012867	Skin	The outer covering of the body that protects it from the environment. It is composed of the DERMIS and the EPIDERMIS.
