Neuroblastoma is the most common extracranial solid tumor in childhood. In different classification of neuroblastomas, a subset of undifferentiated or poorly differentiated tumors with bizarre histological features has been mentioned. A 3-year-old girl presented with abdominal pain. Her haematological and biochemical parameters were normal except her urinary vanelylmandelic acid level was elevated five times the normal value (64.4 IU/ml). On computed tomographyscan, a retroperitoneal contrast-enhancing mass was visible around D12-D13 region (60×52×47mm). Sections of CT guided trucut biopsy revealed large cells with pleomorphic nuclei, abundant cytoplasm and occasional multinucleated giant cells. Immunohistochemistry showed the cells reactive for neuron specific enolase, chromogranin-A, synaptophysin, non-reactive for cytokeratin, desmin and glial fibrillary acid protein and Alk-1. A diagnosis of anaplastic neuroblastoma was made. The child is currently under chemotherapy and doing well. How to cite this article: Roy S, Das I, Nandi A, De S.

Rhinosporidiosis is a granulomatous disorder caused by Rhinosporidium seeberi, an aquatic parasite. It spreads through contaminated water and soil. It frequently involves the nasal cavity and nasopharynx. Disseminated or systemic lesions are rare. A 56 year old man presented with multiple tumor like lesions all over the body in our cancer institute in April 2012. Fine needle aspiration cytology (FNAC) from the skin lesions revealed many sporangia and spores of R. seeberi. He had history of nasal mass being removed by excision and was immunocompetent. Histopathological examination and periodic acid Schiff (PAS) stain confirmed it to be disseminated rhinosporidiosis. His accessible lesions were excised with cautery and he was put on oral dapsone therapy. He did not show recurrence till six months of therapy. A common lesion with an uncommon presentation should not be missed which can increase the morbidity and even mortality in such a case.
