The Effect of Aging on Tissues

The Effect of Aging on Tissues

Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Pigmentation

Pigmentation

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Changes in Skin Color: Clinical Perspectives

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
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Skin Diseases and Disorders

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.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Skin Cancer

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.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Acne Infection

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...

Summary

This study reviews common benign and malignant skin tumors in the elderly, detailing their origins, diagnosis, and treatment options. Early detection and appropriate management are key for better patient outcomes.

Area of Science:

Dermatology
Oncology
Geriatrics

Background:

Skin tumors are common in the elderly, originating from epidermal, melanocytic, or mesodermal tissues.
Benign lesions like seborrheic keratoses and malignant ones such as basal cell carcinoma frequently occur in this demographic.

Purpose of the Study:

To provide a comprehensive overview of skin tumors prevalent in elderly patients.
To outline diagnostic approaches and therapeutic strategies for various skin lesions.

Main Methods:

Review of common benign and malignant skin tumors in the elderly.
Discussion of diagnostic criteria based on tumor characteristics and morphology.
Summary of available treatment modalities including surgical and non-surgical options.

Published on: August 18, 2022

Main Results:

Identified frequent benign tumors (seborrheic keratoses, lentigo) and malignant tumors (basal cell carcinoma, melanoma) in the elderly.
Highlighted the importance of clinical presentation and biopsy for accurate diagnosis.
Detailed various treatment options tailored to lesion type, location, and patient condition.

Conclusions:

Skin tumors in the elderly encompass a range of benign and malignant conditions.
Diagnosis relies on morphology, with biopsy sometimes necessary.
Treatment is individualized, utilizing methods like curettage, cryosurgery, excision, and radiotherapy.
