“…Large SK is in fact an unusual presentation and it is rarely documented in the literature ( Table 1 ). 3 - 6 , 12 - 25 Giant SK have been notably described in genital areas. 4 - 6 , 17 - 20 , 22 - 24 The size of reported giant SK varies from 4.5 to 25 cm in greatest diameter with an average size of 9.8 cm.…”

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.

A Case of Irritated Seborrheic Keratosis Associated with a Previous Incision Site

An 83-year-old woman had undergone an external dacryocystorhinostomy with silicone intubation. Before the surgery, no skin lesions were observed on the incision site. Three months after surgery, the patient complained of a brown-to-black pigmented elevation at her previous skin incision site. A punch biopsy of the pigmented mass was performed. The histopathologic findings confirmed the clinical diagnosis of irritated seborrheic keratosis (SK). SK can occur several months postoperatively and can suddenly increase in size, so surgeons need to carefully check patients' skin prior to surgery. To our knowledge, this is the first reported case of irritated SK discovered on a previous skin incision site.
