Dermatoscopic Findings of Seborrheic Keratosis in Melanoma

Cutaneous melanoma may in some instances be confused with seborrheic keratosis, which is a very common neoplasia, more often mistaken for actinic keratosis and verruca vulgaris. Melanoma may clinically resemble seborrheic keratosis and should be considered as its possible clinical simulator.  We report a case of melanoma with dermatoscopic characteristics of seborrheic keratosis and emphasize the importance of the dermatoscopy algorithm in differentiating between a melanocytic and a non-melanocytic lesion, of the excisional biopsy for the establishment of the diagnosis of cutaneous tumors, and of the histopathologic examination in all surgically removed samples.</p

The lesion appeared on the proximal nail fold, covering half the nail of the second left finger. The nail was thickened and yellowish with longitudinal melanonychia. It was surgically removed with very satisfactory aesthetic results even after 5 years. A review on the subject is also presented

Criocirurgia como tratamento adjuvante na esporotricose: relato de três casos

A esporotricose é doença causada pelo fungo dimorfo Sporothrix spp., e o número de casos vem aumentando, principalmente na cidade do Rio de Janeiro, onde hoje é considerada um problema de saúde pública. O tratamento recomendado é com antifúngicos, mas em caso de persistência das lesões ou quando houver contraindicação, a criocirurgia é opção, pois o fungo é sensível a temperaturas extremas. São relatados três casos de esporotricose tratados com itraconazol e/ou iodeto de potássio durante mais de seis meses com resposta incompleta, nos quais a criocirurgia foi usada com sucesso como tratamento adjuvante
