A rare case of oral adenosquamous carcinoma in a 78-year-old woman is reported. The tumor occurred in her tongue and metastasized to the submandibular and cervical lymph nodes. Histologically, the tumor showed invasive growth involving the submucosal and muscle layers. Its solid carcinomatous nests exhibited ductal differentiation in the deeper aspects and squamous differentiation toward the surface. Histochemical examination revealed an accumulation of acid mucopolysaccharide in the ductal lumina, and the ductal cells were immunohistochemically positive for carcinoembryonic antigen, epithelial membrane antigen, cancer antigen 15-3 and Ulex europaeus agglutinin I. Ultrastructurally, tonofibrils, desmosomes and numerous cytoplasmic processes were common features of the tumor cells. In addition, true glandular structures and pseudocysts were seen in areas. Clinical features of 13 adenosquamous carcinomas in the literature were analyzed.

UI MeSH Term Description Entries
D002272 Carcinoembryonic Antigen A glycoprotein that is secreted into the luminal surface of the epithelia in the gastrointestinal tract. It is found in the feces and pancreaticobiliary secretions and is used to monitor the response to colon cancer treatment.

D017809 Fatal Outcome Death resulting from the presence of a disease in an individual, as shown by a single case report or a limited number of patients. This should be differentiated from DEATH, the physiological cessation of life and from MORTALITY, an epidemiological or statistical concept. Fatal Outcomes,Outcome, Fatal,Outcomes, Fatal

D018396 Mucin-1 Carbohydrate antigen elevated in patients with tumors of the breast, ovary, lung, and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows particularly increased expression in the breast at lactation and in malignancy. It is thus an established serum marker for breast cancer.

D037102 Lectins Proteins that share the common characteristic of binding to carbohydrates. Some ANTIBODIES and carbohydrate-metabolizing proteins (ENZYMES) also bind to carbohydrates, however they are not considered lectins. PLANT LECTINS are carbohydrate-binding proteins that have been primarily identified by their hemagglutinating activity (HEMAGGLUTININS). However, a variety of lectins occur in animal species where they serve diverse array of functions through specific carbohydrate recognition.
