1. Deep dermatophytosis caused by Trichophyton rubrum in immunocompromised patients
Abstract In immunosuppressed patients, dermatophytosis can be more invasive, affecting the dermis and subcutaneous tissues. The authors describe the cases of two patients with kidney and heart transplanted, respectively, that developed a deep dermatophytosis caused by Trichophyton rubrum, confirmed by culture and DNA sequencing. Both patients had concomitant

2. Nail clipping in onychomycosis and comparison with normal nails and ungual psoriasis
Abstract: Background: Of all nail disorders seen in dermatology offices, half of them are due to onychomycosis. The main differential diagnosis is nail psoriasis. The objective of this study was to compare the microscopic findings, other than the presence of fungi, in the clipping of onychomycosis versus normal nails and nail psoriasis. Methods: Cross-sect

3. Prevalence of dermatoses in patients referred for evaluation in an outpatient clinic of specialties
Abstract: Background: Brazilian Unified Health System presents a long waiting period for a dermatology appointment, varying from 34 to 239 days. Objectives: Analyze the prevalence of cutaneous diseases evaluated by dermatologists in a specialized center, in patients referred from the primary care, and to present possible interventions for the primary units

4. In vitro antifungal activity of organic compounds derived from amino alcohols against onychomycosis
Abstract Onychomycosis is a fungal infection of the nail caused by high densities of filamentous fungi and yeasts. Treatment for this illness is long-term, and recurrences are frequently detected. This study evaluated in vitro antifungal activities of 12 organic compounds derived from amino alcohols against standard fungal strains, such as Trichophyton rubru

5. Descriptive analysis of mycological examination of patients with onychomycosis treated in private practice
ABSTRACT This is a retrospective study of 160 patients treated in private practice in São Paulo from March 2003 to March 2015. We analyzed 171 results of direct mycological examinations and fungal cultures from nail scrapings. The agreement between direct mycological examination results and fungal culture was satisfactory, consistent with the literature (ka

6. Subungual squamous cell carcinoma
Abstract Although subungual squamous cell carcinoma is rare, it is the most common primary malignant neoplasms in this location. The higher incidence occurs in the fingernails, but involvement of the toenails is also possible. Subungual squamous cell carcinoma often looks like other more common benign lesions, such as fungal infection, onychomycosis, or vira

7. Nail clipping in onychomycosis
Abstract: Onychomycosis is the most prevalent onychopathy and it requires a correct early diagnosis. Currently, the diagnostic gold standard is the association of direct mycological test with culture; however, it shows variable sensitivity. The histopathological examination of the distal nail plate, called clipping, has shown to be an adjuvant in diagnosing

8. Nail abnormalities in patients with vitiligo
Abstract: Background: Vitiligo is an acquired pigmentary skin disorder affecting 0.1-4% of the general population. The nails may be affected in patients with an autoimmune disease such as psoriasis, and in those with alopecia areata. It has been suggested that nail abnormalities should be apparent in vitiligo patients. Objective: We sought to document the

9. Trichosporon isolation from human ungueal infections: is there a pathogenic role?
Abstract BACKGROUND: Although dermatophytes are considered the major cause of onychomycosis, many reports have incriminated non-dermatophyte moulds and yeasts in the disease’s etiology. Successive Trichosporon isolation from onychomycosis has led to the genus being suspected as a nail primary pathogen. OBJECTIVE: To determine the prevalence of Trichospor

11. Dermoscopy and Onychomycosis: guided nail abrasion for mycological samples
Abstract: Mycological examination is still the cornerstone for the diagnosis of onychomycosis for many dermatologists, but sampling technique interferes on its sensitivity and specificity. Nail abrasion may be used to reach the most proximal part of the lesion and can be easily accomplished with an electric abrasor. We suggest nail plate dermoscopy to identi

12. Scanning electron microscopy of superficial white onychomycosis
AbstractSuperficial white onychomycosis is characterized by opaque, friable, whitish superficial spots on the nail plate. We examined an affected halux nail of a 20-year-old male patient with scanning electron microscopy. The mycological examination isolated Trichophyton mentagrophytes. Abundant hyphae with the formation of arthrospores were found on the nai
