Oral Acantholytic Squamous Cell Carcinoma: A Rare Case of Mandibular Alveolar Ulceration.

Acantholytic squamous cell carcinoma (ASCC) is an atypical form of squamous cell carcinoma (SCC). Although it is well known that ASCC typically appears in sun-exposed regions of the face and neck, oral cavity cases are incredibly rare. In this case report, we present a rare case of a 50-year-old male who developed an ulcer on his right mandibular alveolus, diagnosed with ASCC post-biopsy. On histopathological analysis, acantholytic cells with a pseudo-glandular appearance were observed. Subsequently, the tumor was resected by modified radical neck dissection with a split-thickness graft. The patient responded well to surgery and had no complications post-surgery.
