“…37,38 However, there was no proof that the KAs were correctly diagnosed as such. A malignant course in presumed KA is thought to be more likely the result of diagnostic confusion with well-differentiated SCC than malignant transformation.…”

“…SCCs have the potential to become invasive and metastasize. However, reports of KAs metastasizing have also given support to the idea that KAs are a type of well‐differentiated SCC 18,22 . Other reports propose that similar to actinic keratoses, KAs may belong to a spectrum of premalignant lesions that can transform into SCCs over time 23 .…”

The possibility of rapidly developing actinic keratoses, keratocanthomas, verrucas, and SCC during treatment with sorafenib, warrants close dermatologic follow-up and a lower threshold for biopsy and treatment of suspicious cutaneous lesions. Development of a sorafenib-induced SCC is not an absolute contraindication for continued use of sorafenib therapy; however, the drug should be briefly discontinued until lesions are treated.

“…However, the lesion usually heals in a period shorter than a year and presents a cup-shaped fashion of growth, with lipping of the epidermis at the lateral margins of a solitary cornified crater. Distinction between keratoacanthoma and squamous cell carcinoma is very arbitrary and lesions of great dimensions and aggressive behavior should be treated as squamous cell carcinoma [24], Likely, the socalled atypical pseudoepitheliomatous hyperplasia may in certain cases also be treated as carcinoma [25].…”

Carcinoma Cuniculatum of the Buttock

A rare case of carcinoma cuniculatum involving the buttock in a 56-year-old male is presented. This case is uncommon in that the tumor was largely subcutaneous, while the usual carcinoma cuniculatum is an exophytic growth. Although carcinoma cuniculatum has a wide clinical and histological spectrum, to our knowledge there has been only 1 case with similar histological features, located in a pilonidal sinus, and another case located on the buttock.
