Trichoblastomas are rare cutaneous tumors arising from the hair bulb and mesenchyme. Although they are benign, they can pose a diagnostic dilemma for the clinician and pathologist because they clinically and histologically mimic more common lesions such as basal cell carcinomas (BCCs) and trichoepitheliomas. It is important for the clinician and pathologist to be aware of such tumors and their variants. We present a case of a melanotrichoblastoma, an exceedingly rare variant of trichoblastoma, as well as review the current literature on the clinical presentation and histologic differentiation of these unique tumors with their more commonly seen mimics.
毛母细胞瘤是一种起源于毛球和间充质的罕见皮肤肿瘤。尽管它们是良性的，但它们可能给临床医生和病理学家带来诊断难题，因为它们在临床和组织学上与更常见的病变如基底细胞癌（BCC）和毛发上皮瘤相似。临床医生和病理学家了解此类肿瘤及其变体很重要。我们报告一例黑素毛母细胞瘤，这是毛母细胞瘤一种极其罕见的变体，并回顾了关于这些独特肿瘤及其更常见的相似病变的临床表现和组织学鉴别诊断的当前文献。
