Squamous cell-like proliferations: Differential diagnosis
| Condition[1] | Characteristics[1] | Image |
|---|---|---|
| Invasive squamous-cell carcinoma of the skin | Atypical and pleomorphic keratinocytes, involving the dermis and the sub-cutis with a potential metastatic spread. | 
|
| Actinic keratosis | Atypical keratinocytes confined on basal layer. | 
|
| Bowen | Atypical keratinocytes at every layer of epidermis. | |
| Keratoacanthoma | Symmetrical and circumscribed proliferation of keratinocytes, with central horn plug, with epidermis that extends over the tumor. Highly differentiated SCC. | |
| Queyrat’s erytroplasia | As Bowen, but in the mucosa. | |
| Adnexal carcinomas | Squamous differentiation, but does not show connection with the epidermis and highlights adnexal features. | |
| Adenosquamous carcinoma | Mixed glandular and squamous differentiation. | |
| Verrucous squamous cell carcinoma[notes 1] | Exophytic squamous proliferation with marked papillomatosis and low atypia and the presence of koilocyte-like changes | |
| Epithelioma cuniculatum | Squamous-cell carcinoma of the foot. Histologically is characterized hyperkeratosis, acanthosis with an undulating, densely keratinized, well differentiated squamous epithelium, deeply penetrating the soft tissues. | |
| Inverted follicular keratosis | Sharply circumscribed endophytic verrucous proliferation with prominent squamous features. | |
| Seborrheic keratosis | Acanthosis, absence of atypia, pseudo-horn cysts, in inflamed lesions, mitoses may be present. | |
| Bowenoid papulosis | Atypical keratinocytes and mitoses. Histology similar to Bowen’s disease. | |
| Metastasis | Personal medical history of the patient, nodular proliferation without connection to epidermis, immunohistochemical evaluation. |
Notes
- ↑ When present in ano-genital region, verrucous squamous cell carcinoma is also known with the term of Buschke–Löwenstein tumor
