Lumps and bumps: What not to miss.

The evaluation of pediatric patients with subcutaneous nodules remains a diagnostic challenge. Pediatric dermatologists are regularly confronted with patients who have a nonspecific nodule. Though most masses that require evaluation are ultimately benign, the possibility of a more aggressive process, including borderline or malignant neoplasms, underscores the pivotal role of the pediatric dermatologist in recognizing these lesions. The aim of this review is to provide an overview of lumps and bumps that are important to recognize to prevent delay in diagnosis or treatment of a serious underlying condition. Clinical clues that may lead the pediatric dermatologist to have a higher index of suspicion for more aggressive lesions are reviewed. Suggestions for evaluation and workup, as well as tips for the difficult to discern lesion, are proposed.
