Neurothekeoma2
Neurothekeoma (NT) is a rare benign cutaneous tumor, superficial soft tissue tumors that frequently develop on the head and neck. They often occur in the second and early third decades of life and tend to afflict women more frequently than men. First described by Gallager and Helwig, who proposed the term in order to reflect the presumed origin of the lesion from nerve sheath. Microscopically, the lesions described closely resembled the tumor, "nerve sheath myxoma (NSM)", an entity first described by Harkin and Reed. The latter had, through the years, been variously described as "Bizarre cutaneous neurofibroma", "Myxoma of nerve sheath", and "Pacinian neurofibroma". Clinically, neurothekeomas present as a solitary nodule of the skin. The most common sites of occurrence are the head and neck and the extremities. The lesions range in size from about 0.5 cm. to more than 3 cm. The average patient age is about 25 years, but neurothkeomas may occur at any age. Women are affec ...

List Of Cutaneous Conditions
Many skin conditions affect the human integumentary system—the organ system covering the entire surface of the body and composed of skin, hair, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin.Burns, Tony; ''et al''. (2006) ''Rook's Textbook of Dermatology CD-ROM''. Wiley-Blackwell. . Within the latter type, the hairs occur in structures called pilosebaceous units, each with hair follicle, sebaceous gland, and associated arrector pili muscle. In the embryo, the epidermis, hair, and glands form from the ectoderm, which is chemically influenced by the underlying mesoderm th ...

Myxoid Tumor
A myxoid tumor is a connective tissue tumor with a "myxoid" background, composed of clear, mucoid substance. This tumoral phenotype is shared by many tumoral entities: * Myxomas ** Atrial myxoma ** Odontogenic myxoma ** Cutaneous myxoma ** Intramuscular myxoma * Myxoid hamartoma * Aggressive angiomyxoma * Myxoid leiomyoma * Chondromyxoid fibroma * Myxoid neurofibroma * Nerve sheath myxoma ( neurothekeoma) * Myxolipoma * Angiomyofibroblastoma * Myxoid leiomyosarcoma * Myxoid liposarcoma * Lipoblastoma * Myxofibrosarcoma * Myxoid cortical adenoma * Pleomorphic adenoma * Undifferentiated embryonal sarcoma * Plexiform angiomyxoid myofibroblastic tumor * Myxoid plexiform fibrohistiocytic tumor * Angiomyxolipoma (vascular myxolipoma) * Parachordoma * Acral myxoinflammatory fibroblastic sarcoma Acral myxoinflammatory fibroblastic sarcoma (AMSF), also termed myxoinflammatory fibroblastic sarcoma (MSF), is a rare, low-grade, soft tissue tumor that the World Health Organization ( ...
