We report the clinical findings and evolution of seven patients (five men and two women), the majority of them intravenous drug users, with paracoccidioidomycosis associated to acquired immunodeficiency syndrome (AIDS). In four of the patients the paracoccidioidomycosis was restricted to the lung and in the three others was generalized with cutaneous(More)
BACKGROUND Oral isotretinoin is the criterion standard treatment for severe inflammatory acne associated with scar development. Atypical or exaggerated cicatrization related to oral isotretinoin was reported throughout the 1980s and 1990s. Dermabrasion for atrophic acne scar revision is not recommended 6 to 12 months from the end of oral isotretinoin(More)

Type I collagen is the main dermal component, and its evaluation is relevant to quantitative studies in dermatopathology. However, visual gradation (0 to 4+) has low precision and high subjectivity levels. This study aimed to develop and validate a digital morphometric analysis technique to estimate type I collagen levels in the papillary dermis. Four(More)

OBJECTIVES The clinical significance of nevus-associated melanoma compared with de novo melanomas remains controversial. It has been suggested that nevus-associated melanomas have a higher Breslow thickness and therefore worse prognosis. Over a 10-year period, this study evaluated the incidence of nevus-associated melanoma and its prognostic significance(More)
