Extensive Presentation of Penile Carcinoma Cuniculatum a Variant of Squamous Cell Carcinoma With Low Malignant Potential

Abstract

Carcinoma cuniculatum is an uncommon variation of squamous cell carcinoma (SCC) has been documented in a few cases at various locations of the body such as penis, foot, jaw, oropharynx and esophagus. In this case, a 79-year-old male presents with a penile mass, which he underwent a total penectomy. Histology of the mass was defined as carcinoma cuniculatum with negative margins and no lymphovascular invasion. This variant of SCC rarely metastasizes. A joint decision was made to observe lymph nodes. It is important to differentiate the different SCC because patient care can be guided based on the pathology.
