“…1,45 Inverted growth can also be observed in other skin sites, such as the buttocks, where the tumor presents as an invasive mass with a sinusoidal opening on the surface. 46 It may be more pronounced in men when hair follicles are involved. CVC in the buttocks is more likely to show sinus and purulence than in other areas (Figure 1).…”

Verrucous carcinoma (VC) is a relatively rare locally aggressive, slow-growing, well-differentiated squamous cell carcinoma with minimal metastatic potential and is most frequent in the mucosa. Although rarely reported on the skin, cutaneous verrucous carcinomas (CVC) can appear anywhere, most commonly on the feet. However, clinical and pathologic diagnosis of CVC has been confusing and challenging. It can easily be mistaken for benign or more malignant conditions such as giant condyloma acuminata, keratoacanthoma, and pseudoepithelioma-like hyperplasia or squamous cell carcinoma, resulting in inappropriate management. In this review, we describe the different aspects associated with CVC, including its pathogenesis and clinicopathologic features. The available evidence for the differential diagnosis and treatment of CVC is discussed, and specific management recommendations are made. After the treatment, careful follow-up examinations of the excised area should be performed at regular intervals.

Verrucous carcinoma (VC) is an uncommon, low-grade variant of squamous cell carcinoma. Its benign histologic appearance and indolent course may lead to a delayed diagnosis. We report a rare case of an inverted verrucous carcinoma of the buttock presenting as a slow-growing subcutaneous lesion with a draining sinus and no exophytic component, clinically mimicking abscess and gossypiboma, with magnetic resonance imaging (MRI) and pathologic correlation. Biopsy of the lesional base is mandatory for accurate diagnosis. An enhancement pattern with a convoluted undulating appearance in a subcutaneous lesion displayed on MRI should raise a consideration of inverted VC in the differential diagnosis.
