We report a case of squamous cell carcinoma originated from a sacrococcygeal tailgut cyst in a 73-year-old female patient. Tailgut cysts are generally multilocal and have a layer of either columnar, squamous or transitional epithelium, or a combination of these. This case was treated with surgical excision and radiotherapy. Cancer presentation of a congenital abnormality in old age is a rare entity. This report is the first case of squamous cell carcinoma developing in a tailgut cyst without any synchronization, as an isolated (pure) pathology.

A heterogeneous aggregate of at least three distinct histological types of lung cancer, including SQUAMOUS CELL CARCINOMA; ADENOCARCINOMA; and LARGE CELL CARCINOMA. They are dealt with collectively because of their shared treatment strategy.
A mixed adenocarcinoma and squamous cell or epidermoid carcinoma.
Morphological abnormalities of the cervical EPITHELIUM, usually revealed in PAP SMEAR, which do not meet the criteria for squamous CERVICAL INTRAEPITHELIAL NEOPLASIA or SQUAMOUS CELL CARCINOMAS of the CERVIX . It may be a sign of infection with certain types of human papillomavirus (HPV).or sign of a benign (not cancer) growth, such as a cyst or polyp or, in menopausal women, of low hormone levels. More testing, such as HPV test, may be needed.
A carcinoma arising from MERKEL CELLS located in the basal layer of the epidermis and occurring most commonly as a primary neuroendocrine carcinoma of the skin. Merkel cells are tactile cells of neuroectodermal origin and histologically show neurosecretory granules. The skin of the head and neck are a common site of Merkel cell carcinoma, occurring generally in elderly patients. (Holland et al., Cancer Medicine, 3d ed, p1245)
