Extragonadal teratomas in adults are an extremely rare entity. Teratomas may be mature or immature and are characterized by their midline presentation. We are presenting here a case report of immature teratoma of the palm in a 35-year-old female. The patient developed a recurrent swelling of the palm from which a wedge biopsy was taken and sent for histopathological examination. A diagnosis of "immature teratoma, grade 2" was made, whose margins were compromised. Later on ultrasonography (USG) abdomen and pelvis and whole-body magnetic resonance imaging (MRI) showed no significant findings ruling out the possibility of an occult primary. MRI palm showed a well-defined cystic lesion with loculations suggestive of teratoma. Re-exploration was advised to achieve free margins.
成人性腺外畸胎瘤是一种极其罕见的疾病。畸胎瘤可成熟或不成熟，其特征是呈中线部位表现。我们在此报告一例35岁女性手掌部未成熟畸胎瘤的病例。患者手掌反复出现肿胀，从中取楔形活检组织并送去做组织病理学检查。诊断为“2级未成熟畸胎瘤”，其边缘不完整。随后，腹部和盆腔超声检查（USG）及全身磁共振成像（MRI）未发现明显异常，排除了隐匿性原发灶的可能性。手掌MRI显示一个边界清晰的囊性病变，有分隔，提示为畸胎瘤。建议再次手术以获得切缘阴性。
