Tubular Krukenberg tumor with an occult primary can cause problems in histopathologic diagnosis, by mimicking primary ovarian tumors. We present one such occurrence in a 32year old female who underwent surgery for bilateral malignant ovarian tumor. Gross examination of both ovarian tumors re-vealed bosselated, smooth outer surface with a few cysts on the surface. Cut surface was grey-white to yellowish in colour with cysts filled with serous fluid at the periphery. Microscopic ex-amination revealed mucin laden signet ring cells, predomin-antly showing tubular architecture within a cellular ovarian stroma. The cytoplasm of these cells varied from granular eos-inophilic to pale vacuolated appearance and showed PAS and mucicarmine positive mucin. Differential diagnosis with other primary ovarian tumors is discussed.
