Kaposi Sarcoma can affect the ocular surface and adnexa and can masquerade as other entities, delaying prompt diagnosis can lead to diagnostic wandering delaying treatment. Our aim is to describe a case of KS of the eyelid in an HIV seronegative patient. Case Presentation: A seventy-year-old man developed a bilateral growing tumoral reddish purple vascular mass on both the lower and upper eyelid involving rapidly for 6 months. Both feet and the two shanks show the presence of a brown-violet tumor-shaped formation. The patient was negative for HIV. Histology examination showed a nodular tumor-like mass with a fibro hemangioma-epitheliomatous. Polymerase chain reaction was positive for human herpes virus 8. Initial chemotherapy followed by surgery was proposed to the patient. Unfortunately, the patient rejected treatment and was lost to follow-up. Conclusion: This case reports the difficulty of managing KS in developing countries.展开更多

The majority is asymptomatic, and for this reason, gastrointestinal KS(GI-KS) remains undiagnosed. With continued tumor growth, considerable variation in clinical presentation occurs including abdominal pain, nausea, vomiting, iron deficiency anemia(either chronic or frank gastrointestinal bleeding), and rarely mechanical obstruction alone or combined with bowel perforation. Endoscopy with biopsy allows for histological and immunohistochemical testing to confirm the diagnosis of GI-KS among those with clinical symptoms. In previous studies, dual treatment with highly active antiretroviral therapy and systemic chemotherapy have been associated with improved morbidity and mortality in individuals with visceral KS. Therefore, investigators have suggested performing screening endoscopies in select patients for early detection and treatment to improve outcome. In this review, we describe a 44 years old man with AIDS and cutaneous KS who presented for evaluation of postprandial abdominal pain, vomiting, and weight loss. On upper endoscopy, an extensive, infiltrative,circumferential, reddish mass involving the entire body and antrum of the stomach was seen. Histologic examination later revealed spindle cell proliferation, and confirmatory immunohistochemical testing revealed human herpes virus 8 latent nuclear antigen expression consistent with a diagnosis of gastric KS. Following this, we present a comprehensive review of literature on KS with emphasis on gastrointestinal tract involvement and management.展开更多
