Pseudomonas aeruginosa is an opportunistic, gram negative bacillus that causes serious hospital acquired infections. However, it also causes infections with unusual presentations which are acquired in a non-hospital environment. This report will discuss the pathogenesis, clinical manifestations, and therapy of this uncommon infection, such as: 1) Pseudomonas folliculitis: a superficial or deep bacterial infection associated with the use of public hot tubs, whirlpools and swimming pools. 2) Invasive external otitis: an infection that can progress to skull base mostly associated to elderly diabetic patients. It is usually secondary to aural irrigation with contaminated water. 3) Pseudomonas osteomyelitis: an infection usually associated with nail puncture wounds especially if wearing tennis shoes. 4) Toe with infection: mostly associated with individuals using topical antibacterial agents. 5) Green nail syndrome: a non tender paronychia lesion that appears most often in persons whose hands are constantly exposed to water, soaps and detergents or are subject to mechanical trauma. 6) Corneal ulcer keratitis: mostly associated with the use of soft lenses, eye drops, mascara or contaminated whirlpools. This condition may terminate in panophthalmitis. 7) Endocarditis: most commonly associated with intravenous drug addicts.

Infectious endocarditis is occasionally a complication of Staphylococcus aureus sepsis in previously well individuals with no heart disease or history of intravenous drug use. We report a case of a 16 year old who developed Staphylococcal sepsis and endocarditis probably as the result of neglected paronychia of her toes. Despite adequate antibiotic therapy, the infectious process destroyed her aortic valve, thereby producing aortic regurgitation complicated by cerebral embolism. Aortic valve replacement surgery was required. Endocarditis should always be sought with S. aureus bacteremia. Intravenous high-dose antibiotic therapy for at least 4 weeks is the recommended therapy.

Knowledge of the anatomy and function of the nail apparatus is essential when performing the physical examination. Inspection may reveal localized nail abnormalities that should be treated, or may provide clues to an underlying systemic disease that requires further workup. Excessive keratinaceous material under the nail bed in a distal and lateral distribution should prompt an evaluation for onychomycosis. Onychomycosis may be diagnosed through potassium hydroxide examination of scrapings. If potassium hydroxide testing is negative for the condition, a nail culture or nail plate biopsy should be performed. A proliferating, erythematous, disruptive mass in the nail bed should be carefully evaluated for underlying squamous cell carcinoma. Longitudinal melanonychia (vertical nail bands) must be differentiated from subungual melanomas, which account for 50 percent of melanomas in persons with dark skin. Dystrophic longitudinal ridges and subungual hematomas are local conditions caused by trauma. Edema and erythema of the proximal and lateral nail folds are hallmark features of acute and chronic paronychia. Clubbing may suggest an underlying disease such as cirrhosis, chronic obstructive pulmonary disease, or celiac sprue. Koilonychia (spoon nail) is commonly associated with iron deficiency anemia. Splinter hemorrhages may herald endocarditis, although other causes should be considered. Beau lines can mark the onset of a severe underlying illness, whereas Muehrcke lines are associated with hypoalbuminemia. A pincer nail deformity is inherited or acquired and can be associated with beta-blocker use, psoriasis, onychomycosis, tumors of the nail apparatus, systemic lupus erythematosus, Kawasaki disease, and malignancy.

This article includes the etiology and pathophysiological data of each entity, classifying them as dermatologic, systemic, infectious, neoplastic, traumatic, and other classifications. The entities inherent to the periungual folds are also included, such as acute paronychia, chronic paronychia, retronychia, hangnails, hematomas of the proximal fold caused by oximeter, onychocryptosis, hypertrophy of the lateral folds, and infections caused by Candida albicans, Pseudomonas, and Staphylococcus aureus. Additionally, pathologies caused by diabetes mellitus, sepsis, endocarditis, drug reactions, and finally less frequent diseases that also affect the nail folds are discussed.
