Provisional chapter Chapter 11 Infections, Infestations and Neoplasms of the Scalp Infections, Infestations and Neoplasms of the Scalp Filiz Canpolat Filiz Canpolat Additional information is available at the end of the chapter Additional information is available at the end of the chapter http://dx.doi.org/10.5772/67278 Abstract This chapter reviews common cutaneous infections, infestations, and neoplasms of the scalp. Infections of the scalp are subdivided into three major groups. The most seen are: (1) Bacterial: Folliculitis, folliculitis decalvans, tufted hair folliculitis and acne keloidalis nuchae. (2) Fungal: Tinea capitis, favus and kerion celsi. (3) Protozoal: Syphilitic alope- cia. Pediculosis capitis is the most common worldwide infestation of the scalp. The neo- plasms of the scalp are large group of different diseases due to arising different origin. In the following section, trichilemmal cyst, proliferating trichilemmal cyst, nevus sebaceous and cylindroma are discussed in detail. Keywords: infection, infestation, neoplasm, scalp 1. Introduction Scalp diseases are one of the most seen reasons for admission to dermatology clinics. There is a wide spectrum of different aetiologies for scalp lesions. This chapter will review cutaneous infections, infestations and neoplasms of the scalp. Examples of bacterial infections include folliculitis, folliculitis decalvans, tufted hair folliculitis and acne keloidalis nuchae. There will be some detailed information about fungal infections, such as tinea capitis, favus and kerion celsi. The neoplasms of the scalp represent a varied group of dermatoses. This review focuses on trichilemmal cyst, proliferating trichilemmal cyst, nevus sebaceous and cylindroma. 2. Bacterial infections of scalp There are several types of infections of the scalp including chronic scalp folliculitis [SF], fol- liculitis decalvans [FD], tufted folliculitis [TF], acne nuchae keloidalis [ANK] and dissecting ©© 2016 2017 The The Author(s). -

Approach to Hair Loss in Women of Color Jennifer M
Approach to Hair Loss in Women of Color Jennifer M. Fu, MD, and Vera H. Price, MD, FRCP(C) Hair loss in women of color represents a unique diagnostic challenge that requires a systematic approach. In women of color, clinical examination of the hair and scalp is most helpful when performed first and used to guide subsequent history-taking to arrive at a clinical assessment. The most common hair problems in women of color are hair breakage, traction alopecia, and central centrifugal cicatricial alopecia. A careful detailed clinical examination and history will guide the clinician to appropriate counseling and management. It is important to recognize that a patient may have more than one of these 3 diagnoses and each requires separate attention.

These micro- biota help regulate host immune mechanisms via an interplay between microbes and immune cells, influencing homeostasis and inflammation. Bacteria affect immune responses by controlling the local inflammatory milieu, the breakdown of which can result in chronic inflammatory disorders. Follicu- lar microbiome shifts described in some inflammatory cutaneous diseases suggest a link between their development or perpetuation and dysbiosis.

Streptococcus and Staphylococcus aureus are the most common bacteria causing abscesses of the skin. Cracks and injury to the skin is the usual pathway of entry for the specified bacteria. Fever may be a direct result of the bacteria and the areas of the affected skin usually become swollen, red, tender and warm. Most abscesses resolve quickly once appropriately treated (skinsight.com). Dissecting folliculitis is a rare chronic suppurative disease, usually affecting African American adult males causing alopecia scarring of the scalp (S. Sivakumaran et al, 2001). Many dermatologist and or pathologist receive little to no training is the evaluation of hair disease (Sperling, 2001). This classification of scarring alopecia recognizes five fairly distinct diseases. However, many cases of scarring alopecia will demonstrate clinical and /or histologic features that are shared by more than one diagnostic entity. A sixth category (‘‘scarring alopecia, unclassified‘‘) is needed for cases of scarring alopecia that cannot be confidently identified.
