摘要

恶性黑色素瘤是一种侵袭性的、臭名昭著的肿瘤,在形态和免疫组织化学表达上表现出很大的可变性,因此通常会导致错误的诊断。在黑色素瘤组中,无色素黑色素瘤以其广泛的临床表现、缺乏色素沉着和多样的组织学外观,已经成为一种新的伪装大师。使用免疫组织化学诊断恶性肿瘤,包括黑色素瘤,是原始的和不可或缺的。然而,在抗原表达异常的情况下,问题变得更加复杂。本病例提出了多种诊断挑战的形式,不典型的临床表现,变异形态,以及异常抗原表达。在这里,我们报告一位72岁的男性患者,在他最初的表现时,被认为是肉瘤样间变性浆细胞瘤,但5个月后,另一次来自不同部位的活检显示实际诊断为无色素瘤黑色素瘤。

Amelanotic Melanoma: A Great Masquerader.

Malignant melanoma is an aggressive, notorious tumor showing great variability in morphological and immunohistochemical expression, thus commonly leading to an erroneous diagnosis. Within the melanoma group, amelanotic melanoma, with its wide clinical presentations, lack of pigmentation, and varied histological appearances, has taken on a new persona as a master masquerader. Use of immunohistochemistry in the diagnosis of malignant tumors, including melanoma, is primordial and indispensable. However, the problem gets compounded in scenario of aberrant antigenic expression. The present case posed multiple diagnostic challenges in form of atypical clinical presentation, variant morphology, as well as aberrant antigenic expression. Here, we present the case of a 72-year-old male who, upon his initial presentation, was thought to be sarcomatoid anaplastic plasmacytoma, but 5 months later another biopsy from a different site revealed the actual diagnosis of amelanotic melanoma.
