Clinical spectrum of cutaneous manifestations in renal and renopancreatic recipients in two centers in Uruguay.

Uruguay, with a total population of 3,345,000 inhabitants, is the Latin American country with the second highest number of renal replacement therapies. Long-term immunosuppressant therapy is essential for graft survival but results in reduced immunosurveillance, leading to an increased risk of complications. A variety of dermatological manifestations and a large increase in nonmelanoma skin cancers have been reported in this population.

Melanocytic nevi with special features: clinical-dermoscopic and reflectance confocal microscopic-findings.

Histopathology is considered the 'gold' standard for the diagnosis and classification of melanocytic nevi, but the widespread use of in vivo diagnostic technologies such as dermoscopy and reflectance confocal microscopy (RCM), has enriched profoundly the knowledge regarding the morphological variability in nevi. This is because most morphological observations made via these in vivo tools are closely correlated with features seen in histopathology. Dermoscopy has allowed for a more detailed classification of nevi.

Dermoscopic patterns of 158 acral melanocytic nevi in a Latin American population.

Background: Melanocytic nevi are frequently found on acral volar skin. Differentiation between nevi and melanoma is essential and sometimes difficult, although dermoscopy has enabled a more specific diagnosis of pigmented lesions. Dermoscopic patterns of lesions on acral volar skin have mostly been described in European and Asian populations.

Syringocystadenoma papilliferum arising on the scrotum.

An 8-year-old boy presented to the pediatric dermatology service with an elevated, moist and vegetated pinkish mass, measuring 4 × 5 × 2 cm in diameter, located in the scrotum. The lesion has been gradually increasing in size showing a recent accelerated growth. Excisional biopsy demonstrated the histological picture of syringocystadenoma papilliferum (SCAP).
