Summary
A rare gigantic sebaceous carcinoma developed in a congenital nevus sebaceus on a 53-year-old woman's face. Surgical removal was successful, highlighting the importance of monitoring such lesions for malignant transformation.
Area of Science:
- Dermatology
- Oncology
- Pathology
Background:
- Nevus sebaceus is a congenital skin malformation.
- Sebaceous carcinoma is a rare malignancy arising from sebaceous glands.
Observation:
- A 53-year-old woman presented with a large, growing lesion present since birth.
- The lesion evolved into a massive tumor measuring 110 x 70 x 35 mm on her right cheek.
- Histological examination revealed an invasive dermal neoplasm with atypical cells and foamy cells.
Findings:
- The tumor was diagnosed as sebaceous carcinoma arising in nevus sebaceus.
- Surgical excision, parotidectomy, lymph node dissection, and skin grafting were performed.
- Microscopic analysis showed features consistent with sebaceous carcinoma within a nevus sebaceus.
Implications:
- This case underscores the potential for malignant transformation in nevus sebaceus.
- Early detection and surgical management are crucial for favorable outcomes.
- Further research into the pathogenesis of sebaceous carcinoma in nevus sebaceus is warranted.

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.

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...

01:11Papillary 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.

01:06Multipotency and Niche of Bulge Stem Cell
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...
01:20Accessory Structures of the Skin: Hair Growth and Types
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...
01:16Accessory Structures of the Skin: Hair and Hair Follicles
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...
