Adenoid squamous cell carcinoma is an uncommon variant of squamous cell carcinoma. The lesion is histologically distinctive and it is usually localized on the skin of the head and neck region; it only rarely involves the mucosal sites. The differential diagnoses include adenosquamous carcinoma, adenoid cystic carcinoma, mucoepidermoid carcinoma, basaloid squamous cell carcinoma, and metastatic adenocarcinoma. Surgery is the treatment of choice. The biologic behavior of this neoplasm is more aggressive when it involves mucosal areas, and the prognosis seems worse than that of conventional squamous cell carcinoma.

Purpose A collision tumor consists of 2 different histologically distinct and topographically independent tumors merging in the same mass. In the head and neck region they are rare, with only 4 cases reported in the larynx. Case report A 60-year-old heavy smoker complained of a left submandibular lesion in October 2014. The lesion was excised and showed a poorly differentiated carcinoma, suggestive for adenocarcinoma. After a positron emission tomography-computed tomography scan showed increased metabolic activity in the left laterocervical region and right vocal cord, the patient underwent endoscopic biopsy of the lesion of the left piriform sinus, which was positive for moderately differentiated squamous cell carcinoma (SCC). He was then submitted to circular pharyngolaryngectomy, reconstruction with a radial forearm free flap, and bilateral neck dissection. The histopathologic examination showed an in situ and microinvasive SCC of the left pyriform sinus colliding with a high-grade, non-small-cell neuroendocrine carcinoma of the larynx. Conclusions To our knowledge, this is the first case described of laryngeal collision tumor comprising a neuroendocrine component. The choice of treatment of this kind of lesion is difficult because of the presence of 2 different histologies and of the controversial prognostic correlation of non-small-cell neuroendocrine neoplasms of the head and neck region.
