Epidermal inclusion cysts are benign cutaneous lesions caused by dermal or subdermal implantation and proliferation of epidermal squamous epithelium as a result of trauma or surgery. They are typically located on the scalp, face, trunk, neck, or back; however they can be found anywhere on the body. Lesions are asymptomatic unless complicated by rupture, malignant transformation to squamous cell carcinoma, or infection at which point they can clinically appear as more sinister pathologies. We present the case of a 45-year-old laborer with a ruptured epidermal inclusion cyst, manifesting clinically and radiographically as a malignancy. Following MRI, definitive surgical management may appear to be a logical progression in management of the patient. This case however is a good example of why meticulously following surgical protocol when evaluating an unknown soft tissue mass is imperative. By following protocol, an alternate diagnosis was made and the patient has since gone on to a make a full recovery without life transforming surgery.
表皮样囊肿是由真皮或皮下植入以及表皮鳞状上皮因创伤或手术而增殖引起的良性皮肤病变。它们通常位于头皮、面部、躯干、颈部或背部；然而，身体的任何部位都可能出现。病变通常无症状，除非并发破裂、恶变成为鳞状细胞癌或感染，此时它们在临床上可能表现为更严重的病理情况。我们报告一例45岁劳动者的破裂表皮样囊肿病例，其在临床和影像学上表现为恶性肿瘤。磁共振成像（MRI）检查后，确定性手术治疗似乎是该患者治疗的合理进展。然而，该病例很好地说明了在评估不明软组织肿块时严格遵循手术方案的必要性。通过遵循方案，做出了另一种诊断，患者此后完全康复，无需进行改变生活的手术。
