    ABSTRACT: Rhabdomyosarcoma is a rare tumor, with an annual incidence of 4.3 cases per million children. Even thought, it is the most common soft tissue sarcoma in childhood, with a mean age of 6 to 8 years at diagnosis. A 4 year-old boy presented with a history of a fast growing (1-month) nodular lesion in the caruncle of his left eye. Slit lamp examination showed a vascularized solid nodular lesion in the semilunar fold. The lesion was surgically removed obtaining infiltrated edges with tumoral cells. A second surgery was performed with free tumour edges. The diagnosis of embryonal rhabdomyosarcoma, botryoid type, of intermediate differentiation was made. The treatment for botryoid rhabdomyosarcoma is basically surgical with the combined use of adjuvant polychemotherapy. In adolescent or adult patients (not in infants where growth bone disturbances can occur) external beam radiotherapy can be combined with chemotherapy. Rhabdomyosarcomas of the conjunctiva without orbital extension are rarely reported. We presented a case of a child with a rare tumor which we had a high suspicion of malignancy and early diagnosis and treatment and child is free of systemic disease 6 and half years later. Our research group believes that the key in these tumors is the high index of suspicion and early treatment.

    ABSTRACT: To report a case of extramedullary plasmacytoma of the orbit. A 71-year-old patient presented with diplopia eyelid fullness and limitation of ocular motility in the left eye. Visual acuity was counting fingers, intraocular pressure 34 mmHg and fundus eye examination showed choroidal folds in the involved eye. CT scan showed a mass filling the superior and external left orbit without bone destruction. A biopsy was performed revealing that the tumour was composed of plasmacytoid cells positive with immunohistochemical stains for Kappa light chains and epithelial membrane antigen. Systemic work up was negative. The diagnosis of extramedullary orbital plasmacytoma was made. The patient was treated with external beam radiotherapy (40 Gy) and has remained disease free for four years (49 months). Extramedullary plasmacytomas of the orbit are extremely rare tumours. Accurate and early diagnosis is essential for the therapeutic approach. Extensive medical work up to rule out multiple myeloma or other malignant lymphoproliferative conditions involving the orbit is needed when the diagnosis of orbital extramedullary plasmacytoma is suspected because treatment and prognosis are very different.
