Multiple secondary neoplasms in nevus sebaceus excision

Area of Science:

• Dermatology
• Pathology
• Oncology

Background:

• Nevus sebaceus is a congenital skin malformation.
• It is associated with an increased risk of secondary tumors.
• Management options include observation or surgical excision.

Observation:

• A 19-year-old woman presented with changes in a parietal scalp nevus sebaceus.
• The lesion was surgically excised for further examination.
• Pathological analysis revealed a rare combination of tumors.

Findings:

• The excised nevus sebaceus contained both basaloid hamartoma and syringocystadenoma papilliferum.
• This dual diagnosis within a single nevus sebaceus is exceptionally uncommon.
• The findings underscore the complex histopathological potential of nevus sebaceus.

Implications:

• This case emphasizes the importance of thorough histopathological evaluation of excised nevus sebaceus.
• It contributes to the understanding of the spectrum of secondary neoplasms arising in nevus sebaceus.
• Further research may clarify optimal management strategies and excision timing for nevus sebaceus.
