Low-fat and fat-free pleomorphic lipomas: a diagnostic challenge.

Am J Dermatopathol. 2009 Jul; 31(5): 423-6Sachdeva MP, Goldblum JR, Rubin BP, Billings SDPleomorphic lipomas are benign tumors that most commonly present as subcutaneous masses in the head and neck, shoulder, or back region of middle-aged to elderly men. They are related to spindle cell lipomas based on shared cytogenetic aberrations and histologic features. When little or no fat is present, the diagnosis can be challenging. A review of 38 pleomorphic lipomas seen in consultation revealed 7 cases in which fat was present in reduced (

Topical PRK 124 (0.125%) lotion for improving the signs and symptoms of rosacea.

J Drugs Dermatol. 2009 May; 8(5): 459-62Ortiz A, Elkeeb L, Truitt A, Hindiyeh R, Aquino L, Tran M, Weinstein GBACKGROUND: Current treatments for acne rosacea are often associated with unsatisfactory outcomes and adverse effects. OBJECTIVE: To determine the efficacy and tolerability of a new moisturizing lotion for improving the clinical signs and symptoms of mild-to-moderate acne rosacea. METHODS: In a 12-week, open-label study, a moisturizing lotion containing furfuryl tetrahydropyranyladenine as PRK124 (0.125%, Pyratine-XR, Senetek PLC, Napa, CA) was applied twice daily to subjects with mild-to-moderate rosacea. Improvement in the appearances of erythema and papules were assessed by the treating physician. Skin barrier function was measured by transepidmal water loss after treatment. Tolerability and cosmetic outcome were evaluated by patients. RESULTS: Twenty-one participants completed the study. Overall clinical improvement was observed in 80% of subjects, with most showing mild-t...

Skin tolerance, efficacy, and quality of life

Patients with rosacea and red facial skin often show sensitivity to skin care products which can exacerbate inflammation and subjective irritation. Besides pharmacologic management, special skin care is prudent to avoid cosmetically induced irritation and address cosmetic concerns. Appropriate skin care should provide gentle cleansing, UVA/UVB protection, effective moisturization, and concealing pigments to neutralize the appearance of redness. AIMS: To evaluate skin compatibility and efficacy of a skin care regimen containing licochalcone A (Lic A), an anti-irritant from the licorice plant Glycyrrhiza inflata, for subjects with mild to moderate facial redness. PATIENTS/METHODS: Sixty-two patients with mild to moderate red facial skin used a four-product skin care regimen for 8 weeks. Clinical assessments of erythema and subjective irritation, cross-polarized photography, and self-assessment questionnaires were completed at baseline, and after 4 and 8 weeks of use. A quality of life ...

Rosacea fulminans, pyostomatitis and pyovulvitis in Crohn's disease

Rosacea fulminans (also known as pyoderma faciale) has been reported to occur in association with Crohn's disease. It is still unclear whether the papulopustules and confluent nodules of rosacea fulminans represent a manifestation of mucocutaneous Crohn's disease or whether this association is a mere coincidence. A 46-year-old woman presented with the spontaneous outbreak of rosacea fulminans and pyostomatitis/pyovulvitis. Complete remission of the mucocutaneous symptoms was achieved with 2 months combination therapy with methylprednisolone, isotretinoin and dapsone. The patient's Crohn's disease, already diagnosed for 3 years, did not flare during this period.

Unusual histopathological features of cutaneous leishmaniasis identified by polymerase chain reaction specific for Leishmania on paraffin-embedded ski

Cutaneous leishmaniasis (CL) is rare in Northern Europe and may be overlooked because colleagues have little experience with it. OBJECTIVES: To identify manifestations of CL that may escape diagnosis. METHODS: Correlation of clinical diagnosis and histopathological findings in 28 biopsy specimens taken from 19 patients with CL confirmed by polymerase chain reaction (PCR) specific for Leishmania. RESULTS: In only one patient was the clinical diagnosis CL; other diagnoses included: malignant epithelial neoplasms (5), follicular cyst (2), atypical mycobacteriosis (1), sarcoidosis (2) and lymphoma (1). Lesions were single (15) or few (4) nodules predominantly situated on the extremities or face (16). Histopathological findings were diagnostic of CL in only 10 cases. In nine cases Leishmania was not identified microscopically; histopathological diagnoses were: granulomatous dermatitis (6), lupoid rosacea (1), foreign body granuloma (1) and granuloma annulare (1). Unaltered epidermis (9), n...

Efficacy and safety of once-daily metronidazole 1% gel compared with twice-daily azelaic acid 15% gel in the treatment of rosacea

Rosacea is an inflammatory dermatologic disorder characterized by the presence of facial erythema, visible blood vessels, papules, and pustules. The National Rosacea Society has established a classification system that identifies 4 distinct rosacea subtypes based on clinical presentation: erythematotelangiectatic, papulopustular, phymatous, and ocular. The goal of topical therapy for rosacea is to reduce inflammatory lesion counts; decrease intensity of erythema; and reduce symptoms such as stinging, burning, and pruritus. Metronidazole and azelaic acid are thought to reduce the inflammation associated with rosacea by inhibiting the production of reactive oxygen species produced by neutrophils. Both metronidazole 1% gel and azelaic acid 15% gel recently have been approved for the treatment of rosacea . The current study was conducted to compare the once-daily application of metronidazole 1% gel with twice-daily applications of azelaic acid 15% gel for the treatment of patients with ...

A look at the safety of metronidazole 1% gel

Rosacea is a common, recurrent, inflammatory dermatologic disorder characterized by the presence of facial erythema, visible blood vessels, papules, and pustules. The condition may cause serious psychologic morbidity and may significantly affect quality of life. The first topical rosacea therapy approved by the US Food and Drug Administration was metronidazole for the treatment of inflammatory lesions and erythema . Previously, metronidazole was available as a 0.75% gel. Improved solubility was achieved in a new, stable, aqueous gel that permitted the formulation of metronidazole 1.0%. This new formulation is highly spreadable, easy to use, cosmetically friendly, mild to the skin, nondrying, and moisturizing. The safety of metronidazole 1% gel was determined by the evaluation of its cumulative irritation, contact sensitization, phototoxicity, and photoallergy potential in healthy male and female patients. In this formulation, metronidazole was not irritating under occlusive applicati...
