Summary
Extra ocular sebaceous cell carcinoma, a rare scalp malignancy, was identified without metastasis or Muir-Torre syndrome. Immunohistochemistry confirmed the diagnosis in this extensive cutaneous case.
Area of Science:
- Dermatopathology
- Oncology
Background:
- Extra ocular sebaceous carcinoma is a rare malignancy originating from sebaceous gland epithelium.
- Aggressive variants can present with lymph node and visceral metastasis, indicating a poor prognosis.
Observation:
- This report details a case of extensive cutaneous extra ocular sebaceous cell carcinoma affecting a large area of the scalp.
- The tumor was confined to the scalp without intracranial involvement or distant metastases.
Findings:
- Immunohistochemistry confirmed the diagnosis of sebaceous cell carcinoma.
- The patient showed no evidence of Muir-Torre syndrome, a genetic condition associated with sebaceous neoplasms.
Implications:
- This case highlights a rare presentation of extra ocular sebaceous cell carcinoma.
- It underscores the importance of thorough diagnostic workup, including immunohistochemistry, to rule out systemic involvement and associated syndromes.

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...

01:22Microbiome of the Eye
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
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.
