Patient: Male, 24Final Diagnosis: Ocular Kaposi’s sarcomaSymptoms: Eyelid swelling • red eyeMedication: —Clinical Procedure: BiopsySpecialty: OncologyObjective:Rare diseaseBackground:Ocular Kaposi’s sarcoma (KS) involving the conjunctiva and ocular adnexa is uncommon and is usually treated with cryotherapy or surgical excision. We report a case of ocular KS successfully treated with HAART combined with 8 cycles of weekly docetaxel.Case Report:Our patient was a 24-year-old, treatment-naïve, HIV-positive (CD4 cell count 198 cells/mm3), homosexual man treated as having atypical hordeolum and subconjunctival hemorrhage, and later confirmed with pathology to have ocular KS with immunohistochemistry study showing KS with positive HHV8, CD34, CD31, and focal positive staining with Factor VIIIRA. HAART therapy was initiated combined with weekly docetaxel. With 2-month treatment of HAART and 8 cycles of weekly docetaxel, the KS of the bulbar conjunctiva and the eyelid partially resolved.Conclusions:HAART combined with weekly docetaxel is an effective and well-tolerated option for ocular KS, which could be considered before cryotherapy or surgical excision.

Background Sickle cell hemoglobinopathies are associated with end organ damage but very rarely present with a clinical and laboratory picture of microangiopathic hemolytic anemia (MAHA) and thrombocytopenia, characteristic of thrombotic microangiopathy (TMA). Case presentation We present a patient with HbSC disease who developed thrombotic microangiopathy, needing both RBC exchange transfusion and therapeutic plasma exchange (TPE) for complete clinical recovery. Conclusion Although literature showed therapeutic plasma exchange alone can abrogate a similar clinical scenario, we did an in-depth review which concluded that in most of the TMA cases secondary to sickle cell disease, treatment with both with plasma exchange and red cell exchange transfusion are necessary.

This paper describes a rare case of germ cell cancer with duodenum, brain and lung metastases. The patient presented with melena and left testicle enlargement. Orchiectomy revealed mixed germ cell cancer, enteroscopy revealed duodenal choriocarcinoma, and chest x-ray and computed tomography (CT) showed bilateral lung metastases. The patient received and tolerated cisplatinum-based chemotherapy, and responded well. However, he developed seizures 3 months later. MRI showed brain metastases and he was treated with whole-brain radiation. One month later, he developed progressive dyspnea. Chest CT showed worsening lung metastases. He received second-line chemotherapy, but died due to multiorgan failure. Germ cell cancer with nonpulmonary metastases has poor prognosis and the management of these patients requires a multimodal approach. Head CT should be considered as routine screening for all germ cell cancer patients on initial diagnosis and brain MRI should be considered for high-risk patients (with an embryo- or choriocarcinoma histology, dramatically elevated β-human chorionic gonadotropin and lung involvement).

Painless bleeding in a patient presenting from the community with elevated coagulation studies rarely makes the physicians suspect superwarfarin or rodenticide poisoning. Although a significant number of superwarfarin exposure cases are diagnosed every year, we believe there appears to be delay in diagnosis and confusion in determining what is the ideal way to treat and monitor these patients during the management. This is the first thorough literature review of all the reported cases of superwarfarin poisoning which also studied the clinical presentation, management and follow-up patterns. We present a 70-year-old man who presented to the emergency room with epistaxis, melena, colacolored urine with elevated prothrombin time (PT), activated partial thromboplastin time (aPTT) and international normalized ratio (INR). Mixing studies showed complete correction of coagulopathy indicative of factor deficiency. Additional history revealed that the patient had arguments with family member at home and made us suspect superwarfarin exposure. Qualitative brodifacoum testing was positive and was managed with fresh frozen plasma and high doses of vitamin K1 (phytomenadione) with serial monitoring of INR and clinical symptoms. Superwarfarin poisoning should be considered in the differential diagnosis of a patient who presents with above clinical and laboratory profile especially in the absence of any history of coagulopathy or anticoagulant use. We want to raise public and especially physician awareness that history taking, early diagnosis and managing in right clinical setting play a significant role in survival of these patients.
