ABSTRACT
Plasmacytoid urothelial carcinoma (PUC) is a newly recognized rare variant of urothelial carcinoma, which is now being increasingly diagnosed prospectively as well as by retrospective analysis of cases with a poor prognosis. Morphologically, these tumors simulate plasma cell neoplasms and pose a diagnostic challenge. Identifying this variant is essential in two aspects: therapy and prognosis. Here, we present a case who underwent multiple transurethral resection of bladder tumor (TURBT) procedures, each with a diagnosis of urothelial carcinoma, the plasmacytoid type which was confirmed on radical cystectomy, and after 1 year, the patient presented with duodenal metastasis. We discuss the morphological aspects of differentiating this tumor from variants of urothelial carcinoma and other tumors with a plasmacytoid appearance. Despite the recognition and aggressive treatment, the patient expires within 2 years of the first diagnosis of bladder carcinoma.

Sertoliform endometrioid carcinoma (SEC) is a rare epithelial ovarian cancer which may be mistaken for sex cord tumour on microscopy. Immunohistochemistry and extensive sampling of tumour to look for areas of conventional endometrioid carcinoma are important to confirm the diagnosis of SEC. We report a case of SEC of ovary in a postmenopausal lady who presented to us with abdominal wall abscess in epigastric region.
