A challenging diagnosis of penile sarcomatoid squamous cell carcinoma

We report a patient with penile sarcomatoid squamous cell carcinoma (SCC) initially misdiagnosed as condyloma acuminatum. Sarcomatoid SCC is a rare, aggressive, biphasic cancer that often presents a diagnostic challenge and carries a poor prognosis, especially after a delay in diagnosis. Although sarcomatoid SCC may exhibit a broad range of clinical features, the expression of p63 and keratin 34βE12 is a common finding. Our case highlights the importance of accurate clinicopathologic correlation to facilitate a timely diagnosis and management of this rare and highly aggressive malignancy.
