[Acute leukemia child with ocular Kaposi's sarcoma after hematopoietic stem cell transplantation: a case report and literatures review].

OBJECTIVE

To summarize clinical features of eye Kaposis' sarcoma ( KS ) in leukemia child after peripheral blood stem cell transplantation (PBSCT).

METHODS

One 13 years-old child with acute lymphoblastic leukemia (ALL) and negative HIV test who developed KS restricted in right conjunctiva, cornea and sclera after successful allogeneic PBSCT was reviewed retrospectively.

RESULTS

The child suffered from T cell type ALL. He received immunosuppressive treatment after PBSCT, and had once extensive herpes zoster restricted in skin. Seven months after PBSCT, he had blurred vision with right eye and slowly neoplasm formed in cornea and conjunctiva. Pathological examination confirmed KS with changes like capillary hemangioma, atypical fusiform cell, typical immunochemistry and positive immunofluorescent result of HHV8. He received excision of lump of cornea, conjunctiva, sclera and transplantation of cornea and sclera. Antiviral therapy was given together with anti-infection, prevention of cornea rejection and biotherapy. He kept right eye and hand-move eyesight, survived without GVHD or recurrence of ALL and KS.

CONCLUSION

This was the first ocular KS case in ALL child after PBSCT, without correlation with HIV infection. Complete excision combined with biotherapy was safe and effective for single ocular lesions.
