Paediatric renal neoplasms present special challenges to the surgical pathologists because of their histological diversity. Wilms , tumor is the commonest amongst these. Lack of familiarity with the other pediatric renal neoplasms can lead to erroneous diagnosis. All resected specimens of kidney tumors over a period of 5 years were studied. Out of total 36 cases, there were 27 cases of Wilms , tumor. Amongst the other 9 cases, there were 3 cases of congenital mesoblastic nephroma, 2 cases of multicystic nephroma, 3 cases of clear cell sarcoma and 1 case of rhabdoid tumor. The cases of mesoblastic nephroma and multicystic nephroma are all doing well on follow up but the cases of clear cell sarcoma and rhabdoid tumor were associated with poor prognosis.

Cases of gynaecological malignancies are common albeit speculative in some instances owing to the marked sequential cyclic changes the female genital tract undergoes in a lifetime and also the amplitude of heterogeneity it can present with. Five selected cases posing considerable diagnostic challenges are presented here, among the Cases of Gynecological malignancies those were studied over the period of 3 years. Epithelioid leiomyosarcoma involving uterine corpus and unilateral ovary, high grade serous carcinoma with diffuse involvement of bilateral ovaries as well as endometrium and metastasis from occult gall bladder carcinoma to bilateral cystic ovaries are the first three cases. A case of uterine carcinosarcoma in a younger lady and an immature teratoma of ovary presenting with extensive gliomatosis peritonei are included in the last two cases. Each of these cases posed some unique diagnostic challenges as a virtue of their own.
