Longitudinal study of prognostic factors for localized cutaneous melanoma in patients who have been disease-free for five years.

Most relapses in melanoma patients occur during the first five years after diagnosis. Identifying characteristics associated with recurrence after this period could help delineate guidelines, specifically for follow-up protocols. Objectives: The aim of this study was to identify the prognostic factors for relapse and death caused by melanoma in patients who have been disease-free for five years.

Usefulness of ultrasound in dermatofibrosarcoma protuberans and correlation with histopathological findings: A series of 30 cases.

Background: Small series of ultrasound findings in dermatofibrosarcoma protuberans (DFSP) have been published, but the usefulness of this technique as a preoperative planning tool for tumor resection has not been studied.

Materials And Methods: We retrospectively reviewed patients with DFSP at our hospital that underwent ultrasound examination. Depth of invasion was evaluated by ultrasound and histopathology.

Conventional Photodynamic Therapy for Necrobiosis Lipoidica: Successful Treatment in a Series of 4 Cases.

Necrobiosis lipoidica is a rare chronic granulomatous disease. Multiple treatment approaches are available, but results are generally minimal and inconsistent. Some publications report variable results with photodynamic therapy (PDT) as a second line of treatment for refractory cases.

Ex-vivo confocal fluorescence microscopy for rapid evaluation of renal core biopsy.

Small renal mass incidentally diagnosed are common findings nowadays due to the widespread of imaging. Renal mass biopsy is still underutilized by urologists due to its non-diagnostic rates. Confocal microscopy allows for rapid imaging of fresh tissue samples.
