Summary
Subcutaneous granuloma annulare (GA) presents as asymptomatic nodules in deep skin layers. This case highlights a rare, isolated finger presentation in an adult, emphasizing the need for accurate diagnosis.
Area of Science:
- Dermatology
- Pathology
Background:
- Subcutaneous granuloma annulare (GA) is a benign condition presenting as deep, asymptomatic nodules.
- It can occur with intradermal lesions, though isolated subcutaneous involvement is less common.
Purpose of the Study:
- To report a rare case of isolated, unilateral subcutaneous granuloma annulare on an adult's finger.
- To emphasize the importance of differentiating this condition from similar-presenting entities like rheumatoid nodules.
Main Methods:
- Clinical presentation of a 53-year-old female with asymptomatic nodules on her right ring finger.
- Histopathological examination revealing characteristic features of granuloma annulare.
Main Results:
- Histopathology confirmed a palisading granuloma with degenerated collagen and mucin deposition.
- The case demonstrated isolated and unilateral involvement of a single digit.
Conclusions:
- Isolated, unilateral subcutaneous granuloma annulare on a digit is a rare presentation in adults.
- Accurate histopathological diagnosis is crucial for distinguishing subcutaneous GA from conditions like rheumatoid nodules.

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...

48
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...

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

01:05Accessory Structures of the Skin: Nails
4.2K
Nails are one of the important accessory structures of the skin. They are hard, protective structures that cover the dorsal surface of the distal phalanges of fingers and toes. Nails are composed of specialized keratinized cells and serve various functions, including protection, sensation, and manual dexterity.
The main components of a nail include the following.
Nail Plate: The nail plate is the visible portion of the nail that extends beyond the fingertips or toes. It is a hard, translucent...

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...

The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
