Two cases of melanoacanthoma occurring on oral mucous membranes are presented. Melanoacanthoma is considered to be a benign mixed tumor of keratinoacytes admixed with pigment-laden dendritic melanocytes. All intraoral melanoacanthomas reported thus far have been pigmented lesions of the buccal mucosa and have occurred in young to middle-aged black females. These tumors may grow rapidly and therefore they often mimic the radial growth phase of an intraoral melanoma. Because melanocanthomas have no distinguishing clinical features, biopsy is mandatory.
本文报告了两例发生于口腔黏膜的黑素棘皮瘤。黑素棘皮瘤被认为是一种由角质形成细胞与含色素的树枝状黑素细胞混合而成的良性混合瘤。迄今为止报道的所有口腔内黑素棘皮瘤均为颊黏膜色素沉着性病变，且发生于年轻至中年黑人女性。这些肿瘤可能生长迅速，因此常酷似口腔黑色素瘤的放射状生长期。由于黑素棘皮瘤没有特征性的临床特点，活检是必需的。
