Summary
Sebaceous naevus, a congenital scalp lesion, can present later in life. This case highlights a 45-year-old with acquired plaques, diagnosed histologically as sebaceous hamartoma.
Area of Science:
- Dermatology
- Histopathology
Background:
- Sebaceous naevus (sebaceous hamartoma) is a congenital skin lesion.
- Typically diagnosed at birth, it can sometimes be missed initially.
- Associated risks include benign tumors and rare malignancies.
Observation:
- A 45-year-old patient with a 10-year history of gradually enlarging, bilateral, symmetric pigmented plaques.
- Clinical presentation included temporal and subauricular plaques with a brownish, verrucous, smooth surface.
- Patient also had a history of Biermer's anemia and ophiasic alopecia.
Findings:
- Histological examination revealed acanthosis, papillomatosis, and enlarged sebaceous glands.
- Abnormally high dermal location of sebaceous glands confirmed the diagnosis of sebaceous hamartoma.
- The lesion's presentation mimicked an acquired condition rather than a congenital one.
Implications:
- This case underscores the importance of considering sebaceous hamartoma in adult-onset skin lesions.
- Highlights the diagnostic challenges when congenital lesions present atypically.
- CO2 laser treatment was proposed, indicating therapeutic options for such presentations.
