The authors report a case of exuberant giant condyloma acuminatum of Buschke-Loewenstein in a male patient, slow-growing, progressive and with locally destructive behavior in the inguinal, body of the penis, scrotum, perineal and perianal regions. After surgery he showed no signs of recurrence in 20 months of follow-up. The identification of HPV types 6 and 11 was performed using in situ hybridization.

Onychomychosis, a nail fungus infection is the most frequent nail ailment, constituting about half of all nail disorders. It can be caused by dermatophytes, non-dermatophytes, yeasts and Prothoteca spp. Methods include 5407 samples of patients with suspected onychomycosis, studied from January 2002 to December 2006, by direct mycological examination and fungi culture. The diagnosis of onychomycosis was confirmed in samples from 3822 direct mycological and/or culture positive. The diagnosis was established by culture for fungi. Among the 1.428 identified agents, the dermatophytes were responsible for 68.6% (N = 980) of cases, followed by yeasts with 27.6% (N = 394), non-dermatophytes fungi with 2.2% (N = 31), Prothoteca spp with 0.1% (N = 2), and associations with 1.5% (N = 22). Females were more affected, with 66% (N = 2527) of cases, and the most affected age group ranged from 31 to 60 years of age (median 47 years). Fungal microbiota is often changed in the world, both quantitatively and qualitatively, and is affected by several environmental factors. Thus, the periodic review of the composition of this microbiota is important to evaluate the epidemiology and thus proportion a better therapeutic response.

Genital warts can be diagnosed through physical examination and confirmed by histopathology. Noninvasive methods are useful for ruling out other diagnoses with no harm to the patient. In this study the clinical findings were compared to dermoscopy, reflectance confocal microscopy (RCM), and to histopathology findings, in order to determine possible patterns that can aid diagnosis of the lesion. It was possible to identify structural changes on reflectance confocal microscopy that are already known by dermoscopy, in addition to cellular changes previously seen only by histopathological examination. This study shows the use of reflectance confocal microscopy in cases of genital warts, providing important information that can be used in further studies.

SSKI is an effective drug, with many side effects, but with low frequency. Resolution was for maximum six months of treatment. SSKI has been found to be a very effective drug in this retrospective study of culture-proven cases of cutaneous and lymphocutaneous sporotrichosis. It should be used as first drug of choice especially in resource-limited settings.

The clinical course of pityriasis versicolor varied according to the number of relapsing episodes of the disease analyzed over a period of 12 months and can be classified as follows: pityriasis versicolor with clinical and mycological clearing, relapsing pityriasis versicolor and chronic pityriasis versicolor.
