Summary
A rare skin condition, subepidermal calcified nodule (SCN), presented as a growing papule on an infant's ear. Histologic analysis confirmed the diagnosis, and surgical removal yielded positive results.
Area of Science:
- Dermatology
- Pathology
- Pediatrics
Background:
- Subepidermal calcified nodule (SCN) is an uncommon, idiopathic condition.
- It typically presents as a solitary nodule, often on the head or neck.
Observation:
- A 7-month-old boy presented with a gradually enlarging papule on his right ear, noted shortly after birth.
- Physical examination revealed a 5-6 mm pink, firm papule with a scaly surface and surrounding erythema on the superior helix.
Findings:
- Histologic examination showed epidermal defect with fibrin, chondroid tissue, granulation tissue, and extensive amorphous calcified material in the dermis.
- The findings were consistent with subepidermal calcified nodule (SCN).
Implications:
- Early diagnosis and surgical excision are effective for subepidermal calcified nodules.
- This case highlights the presentation of SCN in infancy, emphasizing the importance of histopathological correlation.

01:27Acne 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...
01:21Accessory Structures of the Skin: Sebaceous Glands
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

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...

01:30Skin 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.
