Giant Trichilemmal Cyst at the Neck Region

Abstract

Trichilemmal cyst (TC) is an adnexal skin tumor that usually occurs on the scalp. There is a female dominance in this tumor. Proliferating pilar tumors or cysts arise from this lesion, and the clinical differential diagnosis from TCs must be taken because of aggressive behavior of proliferating pilar tumor. Trichilemmal cyst usually occurs in hair-bearing areas such as the neck, trunk, groin, and others. In this article, we report a case with giant TC involving the neck region.

Trichilemmal Cyst of the Third Fingertip: A Case Report

“…1 , 8 One additional report exists describing a TC in the neck region extending to the deep cervical structures with an unusual behavior. 9 This is the first case report in the literature in which a TC presented on the fingertip, where there are no hair follicles.…”

Trichilemmal Cyst: A Case Report and Review of Literature

“…Trichilemmal cyst is a benign, adnexal skin tumour usually occuring in scalp. 1 Hair bearing areas such as neck, trunk, groin are other areas of occurrence. There is a female predominance in this tumour.…”

“…These cysts are almost always benign, malignant transformation being extremely rare. 1 They may be sporadic or may be autosomal dominant. 2 Rarely, these cysts can be multiple and progress rapidly, often called as proliferating trichilemmal cysts.…”

Differential diagnosis of soft scalp lumps

“…Trichilemmal cysts usually occur in the hair bearing areas with a predisposition for the scalp, neck, trunk and gluteal region. They have a female dominance and with an age preponderance of over 60 years16 and occasionally reached extreme sizes of over 8 cm in diameter 17 18. Trichilemmal cysts are usually solitary lesions and can increase in size over time.…”
