Squamous-cell skin cancer is one of the main types of skin cancer along with basal cell cancer, and melanoma. It usually presents as a hard lump with a scaly top but can also form an ulcer. Onset is often over months. Squamous-cell skin cancer is more likely to spread to distant areas than basal cell cancer. When confined to the outermost layer of the skin, a precancerous or in situ form of cSCC is known as Bowen's disease.

Bowen's disease (BD) is an in-situ squamous cell carcinoma of epidermis. The etiology of BD is multifactorial with high incidence among Caucasians. BD is common in photo-exposed areas of skin, but other sites can also be involved. Lesions are usually solitary. The morphology of BD differs based on age of the lesion, site of origin, and the degree of keratinization. BD is considered as the lull before the storm, which precedes an overt squamous cell carcinoma. Histopathology is the gold standard diagnostic modality to confirm the diagnosis.

Bowen disease is most commonly found in white patients over 60 years old. Other risk factors include chronic sun exposure, immunosuppression, arsenic exposure and cutaneous human papillomavirus (HPV) infection. HPV types 16, 18, 34 and 48 cause Bowen disease at genital sites; the role of HPV in nongenital cases of Bowen disease is less well defined. HPV types 2, 16, 34 and 35 have been rarely identified within nongenital lesions.
