Hyperpigmentation Associated with Essential Thrombocytosis

Tongue hyperpigmentation associated with chemotherapy

W e demonstrate a new hyperpigmentation on the tongue of a 68-year-old female patient who was diagnosed with stage IIA infiltrating ductal carcinoma of the left breast who underwent modified radical mastectomy followed by a triple chemotherapy regimen which consisted of doxorubicin, docetaxel, and cyclophosphamide. The patient developed the tongue hyperpigmentation a few weeks after the initiat...

Essential Thrombocytosis-Associated Thromboembolism in the Abdominal Aorta

Essential thrombocytosis (ET) is a myeloproliferative disorder characterized by an anomalous increase in platelet production. Many patients with ET are asymptomatic. Few studies have reported ET-associated thromboembolism in large vessels such as the aorta. We report a patient with ET who presented with peripheral embolism from an abdominal aortic thrombus and developed acute limb ischemia. The...

Chemotherapy-associated supravenous hyperpigmentation.

Amlodipine associated hyperpigmentation.

Amlodipine is a potent peripheral and coronary vasodilator with high selectivity for vascular smooth muscle, and is widely used in mild to moderate hypertension, chronic stable angina and vasospastic angina. Its most prevalent side effects are peripheral edema, flushing and headache. Cutaneous adverse reactions associated with amlodipine have been rarely reported. Herein, a male patient is desc...

Dengue fever associated with extreme reactive thrombocytosis

Dengue is an important viral illness which has the potential to progress into dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS). Leucopenia and throm-bocytopenia are the hallmarks of acute dengue which normalise with recovery [1]. Progression from thrombo-cytopenia to severe thrombocytosis is uncommon. We describe a patient presenting with acute dengue, who developed extreme reactiv...
