This chapter provides a comprehensive overview of various skin pathologies, ranging from infectious and inflammatory conditions to genetic syndromes and neoplastic disorders. The chapter delves into skin disorders such as eczema, dry skin (xerosis), and Crohn’s disease, exploring their pathophysiology, clinical features, and management. It also covers rare conditions such as acral peeling skin syndrome, diffuse cutaneous mastocytosis, and peeling skin syndrome, including their genetic underpinnings and diagnostic markers. Fungal infections such as mucormycosis and disseminated fusariosis are examined, along with bacterial causes of skin abscesses and staphylococcal scalded skin syndrome. Additionally, the chapter highlights specific skin manifestations of systemic diseases, such as warfarin-induced skin necrosis and Still’s disease. The importance of Langer’s lines in skin grafting and wound healing is also discussed. The section on dermatological lesions includes insights into skin tags, plantar warts, and palmar callus, providing a broad clinical perspective on skin health.
