Fine-needle aspiration cytology in the diagnosis of malignant proliferating trichilemmal tumor: Report of a case and review of the literature.

29 Sep 2009 Malignant proliferating trichilemmal tumor is a rare cutaneous neoplasm derived from the outer root sheath of the hair follicle. Fine-needle aspiration cytology is being increasingly used in the investigation of primary and metastatic cutaneous ... Read more...

Aberrant expression of class III beta-tubulin in basal cell carcinoma of the skin.

29 Sep 2009 Tubulin is a major component of microtubules. Class III beta-tubulin (beta III) is a neuron-associated beta-tubulin isotype and expressed in the normal central and peripheral nervous systems. According to a previous study, beta III is not expressed ... Read more...

Mutations in lipase H cause autosomal recessive hypotrichosis simplex with woolly hair.

16 Sep 2009 BACKGROUND: Mutations in lipase H (LIPH) are a rare cause of autosomal recessive hypotrichosis (HT) simplex. OBJECTIVE: In this study, we investigated the clinical and molecular basis of HT simplex with woolly hair in 3 nonrelated families. METHODS: ... Read more...

Technical information about 'Hair Follicle'

Definition: A tube-like invagination of the EPIDERMIS from which the hair shaft develops and into which SEBACEOUS GLANDS open. The hair follicle is lined by a cellular inner and outer root sheath of epidermal origin and is invested with a fibrous sheath derived from the dermis. (Stedman, 26th ed) Follicles of very long hairs extend into the subcutaneous layer of tissue under the SKIN.
