Introduction:
Seborrheic keratosis is one of the most common benign epidermal cutaneous lesions encountered by dermatologists and plastic surgeons in their daily practice.
Presentation of the case:
A 66-year-old man was presented with a large verrucous mass on the sacrum and perianal area of 10 years duration. After the diagnosis of SK was confirmed, a complete excision of the lesion was done with coverage of the defect with a partial thikness skin graft, with a good outcome.
Discussion:
Giant Seborrheic keratosis are very rare, and their location on the perianal area is rarer still, with no more than 10 published cases of genital area involvement.
Conclusion:
Giant perianal seborrheic keratoses is a very rare presentation, that may resemble many of the skin disease of that area and should be managed with excision and biopsy to confirm the diagnosis.
