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.

肿块和颠簸：不容错过的

对患有皮下结节的儿科患者进行评估仍然是一个诊断挑战。儿科皮肤科医生经常遇到患有非特异性结节的患者。尽管大多数需要评估的肿块最终都是良性的，但更积极的过程（包括临界或恶性肿瘤）的可能性强调了儿科皮肤科医生在识别这些病变中的关键作用。本综述的目的是概述肿块和肿块，识别这些肿块和肿块对于防止延误诊断或治疗严重的潜在疾病很重要。回顾了可能导致儿科皮肤科医生对更具侵袭性病变产生更高怀疑的临床线索。提出了评估和检查的建议，以及难以辨别的病变的提示。
