Extramedullary hematopoiesis (EMH) is the development of hematopoietic tissue outside the bone marrow and it most often occurs in the liver and spleen. Renal EMH is quite rare, and there are very few case reports concerning the kidney. We describe a case diagnosed with congenital dyserythropoetic anemia presenting with a solitary renal mass with splenomegaly. CECT showed a heterogeneously enhancing mass lesion suggestive of renal neoplasm. Microscopic examination revealed features of extramedullary hematopoiesis. We intend to present this case because of the rarity of EMH in kidney and to emphasize that its possibility should be kept in mind in any case of solitary renal mass, especially in those patients suffering from chronic hematological disorders.

Desmoid tumors are benign neoplasms of fibroblasts characterized by local invasiveness. They often recur after surgical resection. They constitute about 3.5% of all fibrous tissue tumors and 0.03% of all neoplasms. Paraspinal desmoid tumors are rare and only few cases have been reported in the literature. We present an 18-year-old female presenting with a paraspinal mass. Patient had a history of trauma at the same site one year back. FNA (Fine needle aspiration) was done and a diagnosis of benign fibroblastic lesion was made which was later confirmed on histopathology. We present this case on account of its rarity and its importance in the differential diagnosis of post traumatic paraspinal masses.
