Solitary fibrous tumor (SFT) of prostate is an unusual type of mesenchymal neoplasm that can elicit a benign or malignant phenotype. It represents a diagnostic challenge as it can simulate poorly differentiated adenocarcinoma and various mesenchymal neoplasms of prostate. We report a case of prostate SFT in a 54-year-old patient, which was clinically misdiagnosed as nodular hyperplasia of prostate with cystitis. However, on follow-up, he was not relieved by the designated treatment. Furthermore, he complained of exacerbation of symptoms and consequently, had to undergo open prostatectomy. Based on histopathological and immunohistochemical (IHC) assessment, a diagnosis of SFT of the prostate was rendered. Additionally, we have discussed the histological mimics of SFT and the diagnostic and prognostic importance of IHC while evaluating such lesions.

Background and Objective: Primary fallopian tube carcinomas (PFTC) are rare tumors with non-specific clinical presentations. The current case was unique since the tumor was first detected on endometrial curettage and clinicoradiologically was misdiagnosed as endometrial carcinoma.Case Report: A 48-year-old, post-menopausal female presented with one episode of vaginal bleeding. Endometrial curettage showed poorly differentiated carcinoma, while cervico-vaginal Papanicolaou (Pap) smear was negative for malignant cells. Right sided fallopian tube carcinoma in-situ was diagnosed on histopathological examination of surgical hysterectomy with B/L salpingo-oophorectomy specimen. Conclusion: As observed in the current case, unusual tumor histology with broad papillary fronds lined by pleomorphic cells showing nuclear stratification and focal involvement of endometrial curettage specimen may be considered a useful pointer for tubal malignancy.
