Pilomatrixomas, also known as epithelioma calcificans, are benign tumors of hair follicle matrix cells that are often mistaken for other lesions, especially cutaneous abscesses. We report an illustrative case in which a teenage girl developed a red, swollen earlobe that required multiple care visits and interventions until definitive diagnosis and treatment were provided. Although the lesion was initially treated as an abscess, it continued to progress in size and discomfort. The correct diagnosis was established after imaging and complete excision with pathologic examination. Ultimately, our patient was subjected to avoidable procedures that carried the risk of potentially negative cosmetic sequelae before the proper intervention. Although abscesses are common, it is important for clinicians to avoid incision and drainage of lesions, unless the diagnosis is certain.
毛发基质瘤，又称钙化上皮瘤，是毛囊基质细胞的良性肿瘤，常被误诊为其他病变，尤其是皮肤脓肿。我们报告了一个典型病例，一名十几岁的女孩耳垂下出现红肿，经过多次就诊和干预，直到明确诊断和治疗后才得到缓解。虽然该病变最初被诊断为脓肿，但它的大小和不适感持续加重。经过影像学检查和完整切除并进行病理检查后，才做出正确的诊断。最终，我们的患者在接受适当干预之前，经历了一些本可避免的程序，这些程序存在潜在的负面美容后遗症的风险。尽管脓肿很常见，但临床医生应避免对病变进行切开引流，除非诊断明确。
