Sarcomatoid carcinoma of the penis: Clinicopathologic features
Sarcomatoid carcinomas are biphasic tumors, which can occur at any site in the human body. Very few cases have been reported in the literature as arising from the penis. A few studies consider these tumors as a variant of squamous cell carcinoma or a metaplastic differentiation of the mesenchyme. Their clinical behavior is aggressive with both blood borne and lymphatic metastases. Treatment is by surgical excision, and dissected lymph nodes have shown both epithelial and sarcomatous components. We report a 50-year-old gentleman, with a sarcomatoid carcinoma of the penis, which was confirmed immunopathologically. The rarity of this entity makes it a clinicopathologic curiosity.
