Abstract

SANCHEZ, MP et al. Squamous hybrid carcinoma of the sole of the foot. Rev. argent. dermatol. [online]. 2022, vol.103, n.4, pp.21-30. ISSN 1851-300X.

Squamous carcinoma (SCC) is a malignant tumor of the epidermis and its appendages. It is the second most common after basal cell carcinoma and has different clinicopathological variants. The verrucous carcinoma (VC) subtype is a rare variant of SCC with histopathological characteristics and specific behavior. Occasionally, carcinomatous components of conventional squamous cells can be observed in the VC, this entity being called "hybridized" tumors, which represent 20% of cases.We report the case of a 72-year-old male with a large exophytic lesion involving the 5th right toe and foot with a diagnosis of squamous hybrid carcinoma.

The objective of the presentation is to show an infrequent association, emphasizing its close follow-up as it can modify its clinical behavior by spreading to regional lymphnodes.

Keywords : Squamous carcinoma; verrucous; sole; hybridcarcinoma.
