Abstract
Squamous cell carcinoma of the anus is a rare gastrointestinal tract disease. Due to the early presence of symptoms, which include bleeding, soreness and a feeling of resistance in the anus, this disease is usually diagnosed in its initial stages.
The standard treatment consists of a multimodal approach combining radiotherapy and 5-fluorouracil-based chemotherapy with mitomycin or cisplatin. The prognosis is very favorable for most patients with the disease localized only to the anus, yet there are some risks associated with the treatment.
This case report describes the management of a wide range of complications, including 5-fluorouracil-associated cardiotoxicity, development of heparin-induced thrombocytopenia, and thrombotic complications in a patient otherwise standardly treated for squamous cell carcinoma of the anus.
