Printed on acid-free paper Springer is part of Springer Science+Business Media (www.springer.com) Preface to the Second Edition Immunocompromised patients are often some of the sickest patients in the hospital. Dermatologists who focus on inpatient consultations and caring for hospitalized patients are often faced with the gravely ill, severely immunocompromised patient who presents with cutaneous lesions that are a mystery to the primary team and the other involved subspecialty consultants. More often than not these lesions are a sign of an infection, typically one that is potentially life- threatening. Infections in the immunocompromised host often lead to rapid demise, making early recognition of the infectious process crucial to the patient’s survival. Th e dermatologist plays a central role in identifying the pathogenic organism, implementing the appropriate therapy and prolonging or saving a life. Th at is the crux of this book. We have combed the literature carefully and combined what we have read with our experience in caring for these very sick, complex patients to present the cutaneous manifestations of infection in the immunocompromised host. Th is textbook centralizes the available literature on the cutaneous manifestations of infection in the immunocompromised host. Th e book is a collection of well-documented references (confi rmed by biopsy and culture) on specifi c skin lesions of infection that illustrates cutaneous lesions of routine and rare infectious organisms, demonstrates the evolution of skin lesions over time, – with immune reconstitution or with the recovery of neutrophils – and highlights recognizable patterns of infection and likely causes in diff erent clinical settings (human immunodefi ciency virus/acquired immune defi ciency syndrome [HIV/AIDS] vs. post solid organ transplantation vs. neutropenia post chemotherapy vs. bone marrow recovery post hematopoietic stem cell transplantation). We have given particular attention to the pattern of disease produced by routine and opportu- nistic pathogens to simplify the expanding list of infectious disease possibilities and recognize the most likely organism for a given clinical situation (e.g., fever, pneumonia and rash or fever, men- ingitis and rash). Starting with the skin lesion (e.g., acral hemorrhagic bullae or subcutaneous nodules), we present an evidence-based tiered diff erential diagnosis based on a literature review, well-documented case reports and the probability of a specifi c organism manifesting as a specifi c pattern of infection in the immunocompromised patient. Th is approach to skin lesions in the immunocompromised host has resulted in a unique textbook with bold illustrations that can be used as a bedside guide for diagnosis. Th e text has been thoroughly updated and expanded since the fi rst edition to refl ect emerging trends in infectious organisms that cause disease in each subgroup of immunosuppressed patients. A new chapter discussing the role of viruses in potentiating malignancies in the immunocompro- mised patient has been added. Th e collection of images presented here is a rare and precious anthology gathered from our work in the “hospital trenches.” Th is book is written by dermatologists but intended for all physicians who care for immuno- compromised patients, including, but not limited to, internists, transplant surgeons, infectious disease specialists, pediatricians, rheumatologists, and hematologist-oncologists. It is intended to be a diagnostic tool for the clinician, as well as a teaching syllabus for medical students and house staff . v Preface to the First Edition In 1979, after training in internal medicine at the Hospital of the University of Pennsylvania and in dermatology at Columbia-Presbyterian Medical Center, I began performing an in-hospital dermatology consultation service at Columbia. I relished the challenge of treating the sickest patients with the worst rashes. I was often rewarded for a compulsively complete skin examination by fi nding the subtle skin clue which was the diagnostic solution to an otherwise complex clinical problem. Th e patients I treated were usually members of the population of immunocompromised patients, a population whose numbers have increased logarithmically over the past 16 years because of major advances in cancer chemotherapy, transplantation, treatment of autoimmune diseases and the AIDS epidemic. Th e major problem in these compromised patients was often infection. Th e infl ammatory response to the invasive organism was altered by either the primary disease or its treatment. Th us, routine pathogens presented in disguise, and the patient became a living culture plate for oppor- tunistic microorganisms, some of which had never been previously described as human pathogens. Skin lesions had to be evaluated not by the morphology alone, but by the clinical setting in which they occurred. Th ere were no atlases or textbooks available to help me in these critical situations. Nor were there teachers or specialists to depend on for dermatology knowledge and advice in the acute care hospital setting, although the infectious disease experts or intensive care specialists, Harold C. Neu and Glenda Garvey, were always willing to share their considerable expertise and wisdom with me. To fi nd out more about cutaneous lesions in the immunocompromised host, I (or more often the dermatology resident doing consults with me for the month) had to search the literature for case reports which were scattered in all general and subspecialty medical journals. Similarly, the care of the compromised host has been managed by all types of physicians: surgeons, internists, primary care physicians, oncologists, rheumatologists and specialists in AIDS, trans- plantation, infectious disease and dermatology. Th is book is a fi rst attempt to centralize the information on cutaneous lesions of infection in the immunocompromised host; to collect well-documented references (by biopsy or culture) on specifi c skin lesions of infection; to illustrate cutaneous lesions of routine and rare infectious organisms; to demonstrate the evolution of skin lesions over time or with the recovery of neutrophils; to recognize patterns of infection and likely causes in diff erent clinical settings; and to provide a list of pathogens that may cause a particular skin lesion when the host is immunocompromised. Lastly, and perhaps most importantly, this book will be used to teach. I am fortunate to have studied under some of the best physician-teachers, both as a medical student and house offi cer at the University of Pennsylvania Medical Center and as a dermatology resident at the Columbia- Presbyterian Medical Center. I can only try to do as well as those from whom I have learned. Scarsdale, New York Marc E. Grossman, M.D. vii Acknowledgments for the Second Edition Leonard Harber, M.D., former chairman of the department of dermatology at Columbia Presbyterian Medical Center, gave me my start in 1976 by supporting my idea of a dermatology consultation service in the medical center for Presbyterian and Babies Hospital (later renamed NY Presbyterian Hospital and Children’s Hospital of NY). Perhaps the fi rst inpatient consultation service of its kind in dermatology, it morphed under the equally supportive and encouraging department

    CHAPTER e16 Atlas of Skin Manifestations of Internal Disease CHAPTER e16 Thomas J. Lawley Robert A. Swerlick In the practice of medicine, virtually every clinician encounters patients with skin disease. Physicians of all specialties face the daily task of determining the nature and clinical implication of dermatologic disease. In patients with skin eruptions and rashes, the physician must confront the question of whether the cutaneous Atlas of Skin Manifestations Internal Disease process is confined to the skin, representing a pure dermatologic event, or whether it is a manifestation of internal disease relating to the patient’s overall medical condition. Evaluation and accurate diagnosis of skin lesions are also critical given the marked rise in both melanoma and nonmelanoma skin cancer.

COMMON SKIN DISEASES AND LESIONS ( Figs. e16-1 to e16-19) In this section, several common inflamma- tory skin diseases and benign neoplastic and reactive lesions are presented. While most of these dermatoses usually present as a pre- dominantly dermatologic process, underlying systemic associations may be made in some settings. Atopic dermatitis is often present in patients with an atopic diathesis, including asthma and sinusitis.

  • Skin and Soft Tissue Infections Following Marine Injuries
    CHAPTER 6 Skin and Soft Tissue Infections Following Marine Injuries V. Savini, R. Marrollo, R. Nigro, C. Fusella, P. Fazii Spirito Santo Hospital, Pescara, Italy 1. INTRODUCTION Bacterial diseases following aquatic injuries occur frequently worldwide and usually develop on the extremities of fishermen and vacationers, who are exposed to freshwater and saltwater.1,2 Though plenty of bacterial species have been isolated from marine lesions, superficial soft tissue and invasive systemic infections after aquatic injuries and exposures are related to a restricted number of microorganisms including, in alphabetical order, Aeromonas hydrophila, Chromobacterium violaceum, Edwardsiella tarda, Erysipelothrix rhusiopathiae, Myco- bacterium fortuitum, Mycobacterium marinum, Shewanella species, Streptococcus iniae, and Vibrio vulnificus.1,2 In particular, skin disorders represent the third most common cause of morbidity in returning travelers and are usually represented by bacterial infections.3–12 Bacterial skin and soft tissue infectious conditions in travelers often follow insect bites and can show a wide range of clinical pictures including impetigo, ecthyma, erysipelas, abscesses, necro- tizing cellulitis, myonecrosis.3–12 In general, even minor abrasions and lacerations sustained in marine waters should be considered potentially contaminated with marine bacteria.3–12 Despite variability of the causative agents and outcomes, the initial presentations of skin and soft tissue infections (SSTIs) complicating marine injuries are similar to those occurring after terrestrial exposures and usually include erysipelas, impetigo, cellulitis, and necrotizing infections.3 Erysipelas is characterized by fiery red, tender, painful plaques showing well-demarcated edges, and, though Streptococcus pyogenes is the major agent of this pro- cess, E. rhusiopathiae infections typically cause erysipeloid displays.3 Impetigo is initially characterized by bullous lesions and is usually due to Staphylococcus aureus or S.

Pavlović1 ✉, Metka Adamič1 Abstract Ecthyma gangrenosum is a relatively rare cutaneous infection generally thought to be linked to sepsis or bacteremia caused by Pseudomonas aeruginosa in severely ill or otherwise immunocompromised patients. Here we report on a healthy middle-aged couple with a typical ecthyma gangrenosum lesion on their thighs, obviously caused by spreading through intimate contact be- tween two skin surfaces: a sort of “consort kissing ulcer.” Although they declined to allow microbiological sampling, the lesions gradually but completely regressed with oral ciprofloxacin treatment, leaving atrophic scars.

    CASE REPORT Ecthyma gangrenosum caused by Stenotrophomonas maltophilia in a neutropenic leukaemic infant: A case report D K Das,1 MD (Paed), DCH; S Shukla,2 MD (Paed) 1 Department of Pediatrics, Hi Tech Medical College, Bhubaneswar, Odisha, India 2 Department of Pediatrics, SCB Medical College, Cuttack, Odisha, India Corresponding author: D K Das ([email protected]) Ecthyma gangrenosum (EG) is a cutaneous lesion, mostly caused by pseudomonas in immunocompromised patients. Other bacterial and fungal pathogens have also been reported. It can occasionally affect previously healthy children. The cutaneous findings are characterised by small indurated papulovesicles, progressing rapidly to necrotic ulcers with surrounding erythema and a central black eschar. Sites most commonly involved are the buttocks, perineum, limbs and axillae; the face is less commonly involved. We are presenting a rare case of EG in a neutropenic infant who had just completed the induction phase of chemotherapy for acute lymphoblastic leukaemia. The gangrenous lesion was on the face involving the tip of the nose, which is an uncommon location. Blood and pus cultures grew Stenotrophomonas maltophilia, which is a rare cause of EG. The patient was treated with IV antibiotics (colistin for 14 days) and improved. S Afr J Child Health 2016;10(1):99-100.
