Myxofibrosarcoma presenting as an exophytic, multi-lobed nodule on the leg.

Dermatol Online J 2016 Jun 15;22(6). Epub 2016 Jun 15.

University of Kansas School of Medicine.

Myxofibrosarcoma may present as a dermal or subcutaneous nodule, often on the extremity of an elderly patient. We present a case of myxofibrosarcoma on the lower leg of a 77-year-old man, which illustrates the deeply infiltrative growth pattern of these tumors, as well as the potential for superficial biopsies to show lower grade histopathologic features than subsequent excision specimens.

Syphilis in the United States.

Clin Dermatol 2014 Mar-Apr;32(2):213-8

Division of Dermatology, Southern Illinois University School of Medicine, Springfield, Illinois. Electronic address:

Syphilis gained notoriety in the 1500s, when it became widespread throughout Europe. While the origins of syphilis are not certain, recent data have shown that it may have originated in the Americas from a close relative that causes Yaws (Treponema pallidum pertenue).(1) For the past 500years, the disease has shown its various faces all over the world. The 19th century saw an entire medical subspecialty-syphilology (sometimes known as syphilography)-devoted to the study of the great disease, then known as "the great imitator." Syphilis has an entire textbook of presentations and can mimic many other infections and immune-mediated processes. At the beginning of the 20th century, the many faces of the disease led to Sir William Osler's well-known aphorism, "The physician who knows syphilis knows medicine."(2) When penicillin was discovered, and used to treat syphilis in 1943, some thought that syphilis would go by the wayside, but syphilis continued what it has been doing for so many years . . . inconspicuously infecting humans. The United States has seen the incidence of syphilis increase numerous times throughout the past 70years. Every decrease in the incidence of syphilis is followed shortly by an increase. A marked shift in the epidemiology occurred from 1990 to 2000. In the 1990s, syphilis primarily occurred in heterosexual minority groups. In the new millennium, a majority of cases of syphilis are now transmitted among men who have sex with men (MSM).(3) This contribution discusses the incidence of syphilis in the United States and the reasons these trends continue.

Consensus guidelines for the management of plaque psoriasis.

Arch Dermatol 2012 Jan;148(1):95-102

Department of Dermatology, Baylor College of Medicine, Houston, TX 77030, USA.

The Canadian Guidelines for the Management of Plaque Psoriasis were reviewed by the entire National Psoriasis Foundation Medical Board and updated to include newly approved agents such as ustekinumab and to reflect practice patterns in the United States, where the excimer laser is approved for psoriasis treatment. Management of psoriasis in special populations is discussed. In the updated guidelines, we include sections on children, pregnant patients or pregnant partners of patients, nursing mothers, the elderly, patients with hepatitis B or C virus infections, human immunodeficiency virus-infected patients, and patients with malignant neoplasms, as well as sections on tumor necrosis factor blockers, elective surgery, and vaccinations.

Buschke-Ollendorff syndrome: a 32-month-old boy with elastomas and craniosynostosis.

Pediatr Dermatol 2008 May-Jun;25(3):349-51

University of Kentucky College of Medicine, Lexington, Kentucky, USA.

A 32-month-old boy with hypotonia, developmental delay, and multiple craniofacial abnormalities including craniosynostosis presented with numerous nonspecific, flesh-colored papules on his right flank. Upon biopsy, these lesions were diagnosed as elastomas. Similar skin lesions were found in the patient's younger brother. The patient's father and brother had osteopoikilotic lesions on radiography, but the patient did not have these findings. None of the reported cases to date have included craniosynostosis in association with Buschke-Ollendorff syndrome. In addition to the case findings, the report also provides a short and current review of the syndrome.

In pursuit of defining clinical relevance of positive patch tests results.

Clin Dermatol 2007 Sep-Oct;25(5):493-4

The Dermatology Unit, Kaplan Medical Center, Rechovot 76100, Israel.

According to the current classification of clinical relevance of the positive patch test reactions, the positive results of patients who are allergic to various allergens that are not responsible for the present dermatitis do not fit into the category of "relevant to present dermatitis" but should be defined as "relevant to a preceding bout of dermatitis." This seems to us inappropriate and misleading because reexposure to the sensitizing agent would quickly revert their reaction to "relevant to present dermatitis." We suggest an alternative possibility to the current division of the various types of clinical relevance, namely, "relevance to a present allergy other than the presenting dermatitis."

Acneiform eruptions associated with epidermal growth factor receptor-targeted chemotherapy.

J Am Acad Dermatol 2007 Mar 12;56(3):500-5. Epub 2006 Dec 12.

Division of Dermatology, Southern Illinois University, Springfield, IL 62794-9644, USA.

A relatively newer class of chemotherapy agents, known as the epidermal growth factor receptor inhibitors (EGF-RIs), is being used to treat advanced stages of solid tumors. Acneiform eruptions are a frequent adverse effect and one which has been associated with increased survival in some studies. We describe 3 patients who presented shortly after initiation of EGF-RI therapy. Characteristics included an absence of comedones, facial and truncal involvement, and a perifollicular lymphoneutrophilic infiltrate detected on biopsy. Lesion counts were reduced with topical adapalene and oral tetracyclines in two patients. Patient 3 had dramatic clearance with low-dose isotretinoin (20 mg daily) until completion of EGF-RI therapy. Acneiform eruptions are a common adverse reaction to EGF-RI therapy and can be treated with traditional acne therapy. This should not be considered a drug hypersensitivity eruption or allergy, and patients should continue therapy. For patients with severe eruptions, oral isotretinoin is a consideration.

Safety of efalizumab in patients with moderate to severe chronic plaque psoriasis: review of clinical data. part II.

J Cutan Med Surg 2005 Dec;9(6):313-23

University of Western Ontario, Waterloo, ONT, Canada.

Background: The efficacy and safety of efalizumab have been evaluated in multiple clinical trials.

Objective: The purpose of this review is to provide an overview of the safety profile of efalizumab during the clinical trials.

Methods: Twelve-week data from four placebo-controlled trials were pooled and analyzed. Data from patients receiving 13-60 weeks of efalizumab therapy were pooled to evaluate longer-term safety.

Results: The most common adverse events were mild to moderate, self-limiting, flu-like symptoms that were most frequent following the first two efalizumab doses; by the third dose the incidence was comparable to placebo. Serious adverse events were observed in 2.2% and 1.7% of efalizumab- and placebo-treated patients, respectively. Nonserious adverse events leading to withdrawal were infrequent and similar to placebo (2.8% vs 1.8%). There does not appear to be increased risk of end-organ toxicity, infection, or malignancy in efalizumab-treated patients.

Conclusion: Efalizumab was well tolerated, with a favorable safety profile.

Hyperimmunoglobulin E syndrome: two cases and a review of the literature.

J Am Acad Dermatol 2006 May;54(5):855-65

Division of Dermatology, Southern Illinois University School of Medicine, Springfield, Illinois, USA.

Hyperimmunoglobulin E syndrome (HIES) is a rare immunodeficiency associated with elevated serum IgE levels, eczematous skin, recurrent cutaneous infections, and distinctive musculoskeletal features. We report two cases seen at our institution and review the current literature. Patient 1 was an 18-month-old African American boy with recurrent staphylococcal cold abscesses, pneumonia, and bacteremia. He had severely eczematous skin, ultimately complicated by eczema herpeticum. After treatment of systemic infections with culture-directed antibiotics, a brief course of cyclosporine, 5 mg/kg, improved the dermatitis and allowed transition to long-term therapy with oral trimethoprim-sulfamethoxazole. Patient 2 was a 15-year-old Caucasian boy with long-standing HIES. He has been maintained on a regimen of interferon gamma injections given 3 times weekly and monthly intravenous immunoglobulin since the age of 3 years, prophylactic antibiotics, and low-dose fluconazole. He has occasional episodes of cold abscesses and sinusitis, but has had excellent control since institution of this regimen and has not experienced any adverse effects.

Life-threatening paraneoplastic cutaneous syndromes.

Clin Dermatol 2005 May-Jun;23(3):301-6

Division of Dermatology, Southern Illinois University School of Medicine, Springfield, 55026, USA.

Paraneoplastic syndromes are diseases or symptom complexes associated with malignancy, usually internal. In dermatology, we modify the definition to refer to dermatoses associated with internal malignancy. In this article, we discuss the link between malignancy and such dermatologic disorders as acanthosis nigricans, acrokeratosis paraneoplastica of Bazex, dermatomyositis, erythema gyratum repens, necrolytic migratory erythema (glucagonoma syndrome), and paraneoplastic pemphigus and discuss, where such information is known, the mechanism by which these paraneoplastic diseases occur.

Validity and reliability of patient reported outcomes used in psoriasis: results from two randomized clinical trials.

Health Qual Life Outcomes 2003 Oct 8;1:53. Epub 2003 Oct 8.

Center for Health Outcomes Research, MEDTAP International, Inc, Seattle, WA USA.

Background: Two Phase III randomized controlled clinical trials were conducted to assess the efficacy, safety, and tolerability of weekly subcutaneous administration of efalizumab for the treatment of psoriasis. Patient reported measures of psoriasis-related functionality and health-related quality of life and of psoriasis-related symptom assessments were included as part of the trials.

Objective: To assess the reliability, validity, and responsiveness of the patient reported outcome measures that were used in the trials - the Dermatology Life Quality Index (DLQI), the Psoriasis Symptom Assessment (PSA) Scale, and two itch measures, a Visual Analog Scale (VAS) and the National Psoriasis Foundation (NPF) itch measure.

Methods: Subjects aged 18 to 70 years with moderate to severe psoriasis for at least 6 months were recruited into the two clinical trials (n = 1095). Internal consistency reliability was evaluated for all patient reported outcomes at baseline and at 12 weeks. Construct validity was evaluated by relations among the different patient reported outcomes and between the patient reported outcomes and the clinical assessments (Psoriasis Area and Severity Index; Overall Lesion Severity Scale; Physician's Global Assessment of Change) assessed at baseline and at 12 weeks, as was the change over the course of the 12 week portion of the trial.

Results: Internal consistency reliability ranged from 0.86 to 0.95 for the patient reported outcome measures. The patient reported outcome measures were all shown to have significant construct validity with respect to each other and with respect to the clinical assessments. The four measures also demonstrated significant responsiveness to change in underlying clinical status of the patients over the course of the trial, as measured by the independently assessed clinical outcomes.

Conclusions: The DLQI, the PSA, VAS, and the NPF are considered useful tools for the measurement of dermatology-related limitations of functional ability and the frequency, severity and impact of psoriasis symptoms on patients' lives and psoriasis-related quality of life.
