RESUMO
Solitary myofibromas are relatively rare neoplasms but one of the most common fibrous neoplasms occurring in infancy and childhood. Adult cases have also been reported in the literature. We describe here a case report of an eighteen-month-old child who presented with a gradually enlarging nodule in the right breast. The case is presented for an insight into contemporary knowledge about its histogenetic origin, behaviour and prognosis.

Angiosarcomas are uncommon malignant neoplasms characterized by rapidly proliferating extensively infiltrating anaplastic cells derived from blood vessels and lining irregular, blood-filled spaces. The cells manifest many of the functional and morphological properties of normal endothelium. They are collectively one of the rarest forms of soft tissue neoplasms. Here we present two cases of pericardial angiosarcoma, one of them showing widespread dissemination, which caused considerable diagnostic dilemma and the diagnosis could only be established very late in their course of disease.

Placental site trophoblastic tumour is a rare form of gestational trophoblastic disease, which seldom metastasizes. It is chemoresistant though has an excellent prognosis after complete resection of the tumour. Its characterization is thus important for treatment and further management. We present an unusual case who presented with ascites of non-neoplastic origin and was found to have metastases to the lymph node.
