Summary
Actinic prurigo, a rare condition, caused a 13-year-old boy to develop itchy skin lesions and eye inflammation. Treatment with thalidomide significantly improved his symptoms.
Area of Science:
- Dermatology
- Ophthalmology
- Immunology
Background:
- Actinic prurigo is a rare, photosensitive disorder characterized by intense itching and skin lesions.
- It often presents in childhood or adolescence, particularly in individuals with darker skin types.
- Associated symptoms can include ocular and lip involvement.
Observation:
- A 13-year-old male presented with pruritic papular and nodular lesions on his forearms.
- He also exhibited lower lip edema, photophobia, conjunctivitis, and pterygium.
- Skin biopsy revealed histopathological features consistent with actinic prurigo.
Findings:
- Histopathology confirmed acanthosis, spongiosis, and dermal perivascular mononuclear cell infiltration (lymphocytes, plasma cells, eosinophils).
- The patient experienced significant improvement in lesions after treatment with thalidomide 100mg/day.
Implications:
- Thalidomide is an effective treatment option for severe actinic prurigo.
- Early diagnosis and management are crucial to alleviate symptoms and prevent complications.
- Further research into the pathogenesis and long-term outcomes of actinic prurigo is warranted.

Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.

Papillary Dermis
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...

Changes in Skin Color: Clinical Perspectives
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism

Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
