The 5-year overall survival for CCS in Stages III and IV was much worse than Stages I and II. Overall estimated 5- and 10-year survival was approximately 50 and 38%, respectively. Men and women were equally affected and had a median age at diagnosis of 39 years. The most common tumor location was lower limb and hip and the most common site of metastases was the lung.

A 70-year-old man presented to the emergency department with fevers, ankle edema and nausea following a presumed insect bite on his ankle 1 month prior. On examination, he was febrile and had left leg pain with passive range of motion. Laboratory studies revealed anemia, thrombocytopenia, acute kidney injury and elevated aminotransaminases. Due to his recent travel to the Northeastern United States, he was suspected of having a possible tick-borne illness. Serologies were positive for Borrelia burgdorferi, Anaplasma phagocytophilum and Babesia microti, and the patient was diagnosed with Lyme disease, babesiosis and anaplasmosis. He was treated with doxycyline, atovaquone and azithromycin, leading to resolution of symptoms. While co-infection with Lyme disease is common, infection with three tickborne illnesses at one time is relatively rare.

A 47-year-old man with a history of dyshidrotic eczema presented to the emergency department with diffuse erythema, chills and pruritus of three weeks’ duration. The patient had received two injections of methotrexate in the preceding two weeks, both of which had failed to improve his whole-body erythema and pruritus. In the emergency department, the patient was evaluated for infection and admitted for the dermatology consultation. After being seen on the general medical floor by the dermatology service the diagnosis of erythroderma was made and the patient was treated with intravenous (IV) cyclosporine therapy, with which his rash dramatically improved over three days. This case report summarizes the presentation and differential of erythroderma, and highlights the importance of having a high index of suspicion for this potentially fatal disease.
