RESUMO
In a case of conjunctival malignant melanoma involving the cornea, we evaluated the findings of H,E, Fontana-Masson, S-100 protein, HMB 45 stain after the localized excision in 39 years old male patient. B-scan ultrasonography, orbit, MRI, Ga citrate scanning and bone scan showed no metastasis to the intraocular tissue, orbital adnexae and other organs. In H-E stain, spindle cells containing melanin pigment which was growing diffusely underneath the conjunctival epithelium could be seen. Fontana-Masson and S-100 protein staining resulted in diffusely positive findings, Therefore we could diagnose as 8 spindle B type malignant m.elanom.a. By histopathological examination, in a case of confirmed spindle B type COunctival malignant melanoma involving the cornea, good result, could be obtained by localized excision followed by 11 months.

Renal angiomylipomas are uncommon benign neoplasms composed of mature fat tissue, thick-walled blood vessels and smooth muscle in varying proportions, which can be commonly diagnosed by those unique fat nature in abdominal ultrasonography and abdominal CT scan. Renal angiomyolipomas without demonstrable fat component are rarely reported which is difficult to differentiate from renal cell carcinoma. We report a case of renal angiomyolipoma without demonstrable fat component which was proven to positive HMB-45 stain after partial nephrectomy.
