A 71-year-old male came to our clinic complaining of a painful solitary erythematous pedunculated nodule on the left popliteal area. It had a clinical presentation similar to that of a pyogenic granuloma which is usually a solitary, sessile or pedunculated, friable papule. The patient said that the lesion had grown up to 1.0 x 0.4 cm in size since 3 years ago and occasionally bled. Skin biopsy taken from the lesion showed atypical keratinocytes disorderly arranged throughout the epidermis. Non-specific proliferations and dilatations of vessels were noted in the upper dermis. From these findings the lesion was diagnosed as Bowen’s disease and surgically removed and the patient is under observation without recurrence. Occasionally, skin malignancy presents atypical clinical manifestation and mimics various other cutaneous skin diseases. In this situation, diagnosis and proper management would be delayed. There are 19 reported cases of skin malignancy mimicking pyogenic granuloma: cutaneous metastasis (6), melanoma (6), Kaposi’s sarcoma(3), Lymphoma(2), Hidradenocarcinoma(1), basal cell carcinoma(1). While 19 cases of other skin malignancy mimicking pyogenic granuloma have been reported, there was no reported case of Bowen’s disease. So we herein report a first case of Bowen’s disease mimicking pyogenic granuloma.
