A Rare Cutaneous Adnexal Tumor: Malignant Proliferating Trichilemmal Tumor
Proliferating trichilemmal tumors (PTTs) are neoplasms derived from the outer root sheath of the hair follicle. These tumors, which commonly affect the scalp of elderly women, rarely demonstrate malignant transformation. Although invasion of the tumors into neighboring tissues and being accompanied with anaplasia and necrosis are accepted as findings of malignancy, histological features may not...
متن کاملA Rare Cutaneous Adnexal Tumour with a Rare Presentation
c Abstract: Proliferating Trichilemmal Tumour (PTT) is a rapidly growing large cutaneous adnexal neoplasm. Although biologically considered as benign, it may be locally aggressive. Malignant transformation of these lesions, known as Malignant Proliferating Trichilemmal Tumour (MPTT) has rarely been reported. So far in the literature, only 39 well-documented cases of MPTT have been reported. MPT...
متن کاملTreatment of Malignant Cutaneous Adnexal Neoplasms.
Malignant cutaneous adnexal neoplasms form a group of rare, typically low-grade-malignancy carcinomas with follicular, sebaceous, apocrine, or eccrine differentiation or a combination of the first 3 subtypes. Their clinical presentation is usually unremarkable, and biopsy is required to establish the differentiation subtype and the definitive diagnosis. Due to their rarity, no clear consensus h...
متن کاملTransgenic mouse model of cutaneous adnexal tumors
TMEM207 was first characterized as being an important molecule for the invasion activity of gastric signet-ring cell carcinoma cells. In order to unravel the pathological properties of TMEM207, we generated several transgenic mouse lines, designated C57BL/6-Tg (ITF-TMEM207), in which murine TMEM207 was ectopically expressed under a truncated (by ~200 bp) proximal promoter of the murine intestin...
متن کاملRetrospective study of rare cutaneous malignant adnexal tumors of the head and neck in a tertiary care cancer hospital: a case series
BACKGROUND Adnexal tumors of the skin are a large and diverse group of benign and malignant neoplasms, which exhibit morphological differentiation toward one of the different types of adnexal epithelium present in normal skin and they pose a diagnostic challenge. The purpose of this study is to share our experience with these rare but aggressive tumors at a tertiary care cancer hospital in a de...
