摘要

摘要:皮肤蜕皮症是一种极为罕见的疾病,临床表现为皮肤上的结节性病变,如疤痕或肿瘤。从组织学角度来看,这可能会给模拟包括肉瘤在内的恶性上皮样肿瘤的诊断带来挑战。组织学上可观察到大的单形上皮样细胞的结节状生长模式。蜕皮病中的上皮样细胞可表现为非典型,核多形,模仿恶性肿瘤。不熟悉妇科病理学的皮肤病理学家可能会将这些特征误解为原发性皮肤或转移性恶性肿瘤。如果不能正确诊断这种情况,可能会给患者带来不必要的诊断检查。本文报告了一例 35 岁剖宫产疤痕妇女的皮肤蜕皮症。组织学检查显示,大的上皮样细胞呈结节状增生,胞浆呈淡嗜酸性,核大,核仁突出。部分区域出现类似子宫内膜腺体的压迫性萎缩裂隙样腺体。蜕膜细胞的组织病理学特征以及适当的免疫组化研究有助于确定诊断,并排除其他模仿蜕膜增生症的肿瘤。

Cutaneous Deciduosis: A Rare Cutaneous Lesion Mimicking Malignancy.

Abstract: Cutaneous deciduosis is an extremely rare condition that clinically presents as a nodular lesion in the skin as a scar or neoplasm. Histologically, this may pose a diagnostic challenge simulating malignant epithelioid neoplasms including sarcoma. Histologically, a nodular growth pattern of large monomorphic epithelioid cells is observed. The epithelioid cells in deciduosis can appear atypical with considerable nuclear pleomorphism, mimicking a malignancy. These features can be misinterpreted as a primary cutaneous or metastatic malignancy by dermatopathologists who are not familiar with gynecologic pathology. Failure to correctly diagnose this condition may result in unnecessary diagnostic studies for the patient. In this article, we report a case of cutaneous deciduosis in a 35-year-old woman with a cesarean scar. Histological examination revealed nodular proliferation of large epithelioid cells with pale eosinophilic cytoplasm and large nuclei with prominent nucleoli. Compressed atrophic slit-like glands resembling endometrial glands were present in some areas. Histopathological features of decidual cells, along with appropriate immunohistochemical studies, help establish the diagnosis and rule out other neoplastic mimics of deciduosis.
