RESUMEN
A 20-year-old male patient presented with painful swelling around left elbow joint. Radiographic examination revealed osteolytic lesion with pathological fracture of lower end of humerus and upper radius. Upper end of ulna was completely absent along with bony erosion. Histopathology of the bony tissue revealed hemangioma-like lesion composed of vascular channels lined by benign endothelium replacing bone. The diagnosis of Gorham's massive osteolysis was made. Gorham's disease is a benign self-limiting condition affecting any age, may involve any part of the skeleton and is characterized by replacement of bone by hemangiomatous tissue resulting in formation of lesions exhibiting massive osteolysis, which may be to the extent of disappearance of the affected bone in radiograph. This nonhereditary case was not associated with nephropathy, which is often a coexistent condition. The case is being reported for its rarity.
RESUMEN
Malignant tumors of the vagina in infants and children are rare, with primary germ cell tumor (endodermal sinus tumor [EST]) being rarer, which carries a dismal prognosis. This tumor is often clinically mistaken as botryoid rhabdomyosarcoma and, on histopathological examination, is often misdiagnosed as clear cell adenocarcinoma. Two cases of EST of the vagina in infants aged 9 and 17 months are reported. Both the patients presented with bleeding per vagina and clinically and by ultrasonography were diagnosed as sarcoma botryoides. Both were diagnosed as primary yolk sac tumors. The serum alfa fetoprotein (AFP) level was 4325 and 9328 ng/ml, respectively. One patient aged 9 months expired 2 months after receiving chemotherapy. The other, aged 17 months, was given chemotherapy followed by surgery with reduction of the AFP levels.
