Ameloblastoma is an uncommon locally invasive benign odontogenic tumor arising from the odontogenic epithelium. It is a slow-growing tumor with locally aggressive nature, and posterior mandible is the most common location. The recurrence rate is high even after resection. Acanthomatous ameloblastoma is one of the rare variants of ameloblastoma and is usually seen in older age group. Here, we present a case of acanthomatous ameloblastoma in a 46-year-old female who previously diagnosed and treated for a case of plexiform ameloblastoma 17 years back. This is the first case to be reported among ameloblastoma with different histopathological variants at recurrence.
成釉细胞瘤是一种罕见的、起源于牙源性上皮的局部侵袭性良性牙源性肿瘤。它是一种生长缓慢但具有局部侵袭性的肿瘤，下颌骨后部是最常见的发病部位。即使切除后，其复发率也很高。棘皮瘤型成釉细胞瘤是成釉细胞瘤的罕见变异型之一，通常见于老年人群。在此，我们报告一例46岁女性的棘皮瘤型成釉细胞瘤病例，该患者17年前曾被诊断并治疗过一例丛状型成釉细胞瘤。这是首例报道的复发时具有不同组织病理学变异型的成釉细胞瘤病例。
