Verrucous cysts are a cutaneous condition that resemble epidermoid cysts except that the lining demonstrates papillomatosis.

Epidermoid Cyst
An epidermoid cyst or epidermal inclusion cyst is a benign cyst usually found on the skin. The cyst develops out of ectodermal tissue. Histologically, it is made of a thin layer of squamous epithelium. Signs and symptoms The epidermoid cyst may have no symptoms, or it may be painful when touched. It can release macerated keratin. In contrast to pilar cysts, epidermoid cysts are usually present on parts of the body with relatively little hair. An epidermoid cyst is one type of vaginal cysts. Although they are not malignant, there are rare cases of malignant tumors arising from an epidermoid cyst. Epidermal inclusion cysts account for approximately 85–95% of all excised cysts, malignant transformation is exceedingly rare. The incidence of squamous cell carcinoma developing from an epidermal inclusion cyst has been estimated to range from 0.011 to 0.045%. Diagnosis Epidermoid cysts are usually diagnosed when a person notices a bump on their skin and seeks medical attention. The ...

Papillomatosis
Papillomatosis of skin is skin surface elevation caused by hyperplasia and enlargement of contiguous dermal papillae.Kumar, Vinay; Fausto, Nelso; Abbas, Abul (2004) ''Robbins & Cotran Pathologic Basis of Disease'' (7th ed.). Saunders. Page 1230. . These papillary projections of the epidermis form an undulating surface under microscopic examination. See also * Skin lesion * Skin disease * List of skin diseases * Papilloma * Laryngeal papillomatosis Laryngeal papillomatosis, also known as recurrent respiratory papillomatosis (RRP) or glottal papillomatosis, is a rare medical condition in which benign tumors (papilloma) form along the aerodigestive tract. There are two variants based on the a ... References External links {{Clinical and histological nomenclature for skin lesions Dermatologic terminology ...

Milium (disease)
A milium (''plural'' milia), also called a milk spot or an oil seed, is a clog of the eccrine sweat gland. It is a keratin-filled cyst that can appear just under the epidermis The epidermis is the outermost of the three layers that comprise the skin, the inner layers being the dermis and hypodermis. The epidermis layer provides a barrier to infection from environmental pathogens and regulates the amount of water rele ... or on the roof of the mouth.Freedberg, et al. (2003). ''Fitzpatrick's Dermatology in General Medicine''. (6th ed.). McGraw-Hill. . Milia are commonly associated with newborn babies, but can appear on people of all ages. They are usually found around the nose and eyes, and sometimes on the genitalia, often mistaken by those affected as warts or other sexually transmitted diseases. Milia can also be confused with stubborn whiteheads. In children, milia often disappear within two to four weeks. For adults, they can be removed by a physician (a dermatologi ...

Skin Lesion
A skin condition, also known as cutaneous condition, is any medical condition that affects the integumentary system—the organ system that encloses the body and includes skin, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. Conditions of the human integumentary system constitute a broad spectrum of diseases, also known as dermatoses, as well as many nonpathologic states (like, in certain circumstances, melanonychia and racquet nails). While only a small number of skin diseases account for most visits to the physician, thousands of skin conditions have been described. Classification of these conditions often presents many nosological challenges, since underlying causes and pathogenetics are often not known. Therefore, most current textbooks present a classification based on location (for example, conditions of the mucous membrane), morphology ( chronic blistering conditions), cause (skin conditions ...
