Disseminated iatrogenic upper gastrointestinal Kaposi sarcoma following prolonged steroid use in a patient with Crohn's disease: a case report.
Article in Journal of medical case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundKaposi sarcoma is a malignant vascular neoplasm caused by human herpesvirus-8. It is mostly seen in immunocompromised individuals, particularly those with human immunodeficiency virus/acquired immunodeficiency syndrome or organ transplants. Cutaneous and mucosal Kaposi sarcoma manifestation is common; however, Kaposi sarcoma may involve the visceral organs. Iatrogenic or drug-induced Kaposi sarcoma may develop in immunocompromised patients undergoing immunosuppressive medication. It is quite uncommon for patients with inflammatory bowel diseases on immunosuppressive medication to develop intestinal Kaposi sarcoma. This case report describes the clinical presentation of steroid-induced disseminated upper gastrointestinal Kaposi sarcoma in a patient with underlying Crohn's disease and examines the management approach, associated challenges, and clinical outcome. CASE PRESENTATION: We report a rare case of iatrogenic Kaposi sarcoma in a 39-year-old African male patient with Crohn's disease undergoing long-term corticosteroid treatment. Patient history, clinical examination, and investigations revealed mucosal Kaposi sarcoma with human herpes virus-8 positivity. This prompted discontinuation of corticosteroids with subsequent transition to infliximab a biologic agent. During the course of treatment with infliximab, the patient presented with extensive Kaposi sarcoma and was started on systemic chemotherapy with improvement.
conclusionThis case underscores the importance of maintaining a high index of suspicion for Kaposi sarcoma in patients on chronic immunosuppressive therapy who present with unusual skin or mucosal lesions.
