Adenoid squamous cell carcinoma (ASCC) is a one of the histological variants of oral squamous cell carcinoma with a rare occurrence of less than 4% of all the cases. The tumour has a slight male predilection with lower lip being the most affected site. ASCC is said to have a varied biologic behaviour which accounts for its ability to metastasize to distant sites and hence has poor prognosis. The histopathology shows numerous duct-like structures with central acantholytic cells. Distinct cytological atypia is seen which aids in diagnosis of SCC. Special stains help in differentiating the tumour from other variants of SCC. The presented case of a 70-year-old female emphasizes the importance of histopathogical examination of the unusual and rarely observed ASCC which can be missed due to similarities with other entities. Recurrence rates being very high, proper treatment starting with definitive diagnosis is imperative. Keywords: Acantholysis, Adenoid features, Ductlike, Oral squamous cell carcinoma.
