RESUMO
Collision tumours, characterized by the simultaneous occurrence of two distinct neoplasms within the same anatomical site, are exceedingly rare in oral pathology. This case report presents an uncommon collision tumour involving desmoplastic ameloblastoma and squamous odontogenic tumour in the anterior maxilla of a 52-year-old male from the Indian population. Desmoplastic ameloblastoma is a variant of ameloblastoma known for its unique histopathological features, while squamous odontogenic tumour is a benign epithelial odontogenic tumour with distinctive clinical behaviour. The rarity of this occurrence emphasizes the need for accurate diagnosis and effective treatment strategies. This report discusses the clinical presentation, radiographic findings, and histopathological characteristics of this collision tumour. Through the presentation of this case, we aim to contribute to the understanding of these rare entities and their management considerations.
RESUMO
Leiomyosarcoma and its pleomorphic variant are rare entities in the head and neck region. Since they usually present as slow growing, discrete firm, and non-ulcerated painless mass, they seem to be deceptively benign and are thus misdiagnosed. Histopathological and immunohistochemical studies are the ways of getting a definitive diagnosis. Till date surgery has been the primary treatment but effectiveness of radiotherapy/chemotherapy is still questionable. Here, we describe a case of leiomyosarcoma in mandible along with discussion about the ways of diagnosis, its differentiation with its pleomorphic variant and their managements.
