Giant perianal seborrhoeic keratosis mimicking Condylomata acuminata

Seborrheic Keratosis: Report of a Rare Presentation and Reminder of the Current Knowledge of the Problem

A 75-year-old man presented with an abdominal enlarging painless tumor of the skin evolving over the last 30 years. His past medical history was unremarkable. Physical examination revealed a brownish pedunculated cutaneous mass which had an irregular keratotic warty surface with no discharge or ulceration. The mass was clinically presumed to be a melanocytic tumor, or a verrucous carcinoma. A monoblock excision of the mass was performed with a good outcome. The specimen was then sent to our pathology department to rule out malignancy. Macroscopic examination revealed a brownish tumor of 7.5 × 7 × 1.5 cm which had fissures and cauliflower-like appearance. Final histological report concluded to a giant seborrheic keratosis.

Giant perianal Seborrheic keratosis: A case report

•

Giant perianal Seborrheic keratosis is a rare form of the sidease that can be misdiagnosed with other skin conditions.

•

The diagnosis of Seborrheic keratosis requires biopsy and histopathologic examination of the lesion.

•

Treatment of giant lesions at the genital area can be successfully made with skin grafting and proper soft tissue coverage.

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.

Giant perigenital seborrheic keratosis

Seborrheic keratosis (SK) is a very common benign epidermal proliferation that is prevalent in all races. Most commonly occurring on the trunk, face, scalp, and the extremities, they can occur anywhere on the body except the palms and soles. The most common appearance is that of a very superficial verrucous plaque which appears to be stuck on the surface. Giant lesions are very rare, and their location on the genital area is rarer still. We report here a case of multiple giant SK lesions in a 59-year-old man.
