Malignant rhabdoid tumor is a well-established clinicopathologic entity occurring classically in the kidney and central nervous system in children. Cutaneous origin has rarely been reported. We herein report a male newborn infant presented with an erythematous and ulcerated mass on his lower back at birth and was found to be a malignant rhabdoid tumor, diagnosed by histopathologic and immunohis...

BACKGROUND Renal transplant recipients have increased risk for developing malignant diseases because of immunosuppression or donor-to-recipient transmission. Malignant rhabdoid tumor (MRT) is a rare, highly aggressive and lethal tumor primarily affecting the kidney of infants and young children. MRT has not been reported in the renal allograft of an adult recipient after kidney transplantation....

UNLABELLED We present here an intriguing case of sporadic renal haemangioblastoma occurring in a 61-year-old male. The tumor consisted of nests of polygonal cells and abundant capillary networks. The neoplastic cells generally showed abundant eosinophilic cytoplasm and prominent eccentric nuclei, resembling the rhabdoid cells. Pronounced intranuclear cytoplasmic pseudoinclusions were another si...

It is well known that malignant melanoma sometimes shows a variety of cytomorphological and architectural features, such as balloon cell, small cell, signet-ring cell, myxoid, and adenoid (pseudoglandular) types [1-4].
