“…Nabi [2], Mohan [3] and Rahmanou [4] also excluded another source for squamous cell carcinoma involving the prostate based on a normal cystoscopy exam (Table 2). The patient reported by Okada [5] underwent transurethral biopsy with no evidence of vesicle or urethral malignancy (Table 2). In addition to the case presented by Parwani [1], we identified just one more situation, described by Sarma [6], in which the diagnosis was made after cystprostatectomy procedure.…”

We report a case of pure squamous cell carcinoma involving the prostate and urinary bladder and describe the diagnostic dilemmas that we faced in trying to determine its origin. The patient was diagnosed ten years ago with prostatic adenocarcinoma treated with radioactive seed implantation. During the last year he also underwent a TURP procedure for urinary obstruction complicated by multiple infections. Postsurgery, the patient developed colo-urethral fistula and decision to perform cystprostatectomy was taken. Excision illustrated a tumor mass replacing the entire prostate that microscopically proved to be squamous cell carcinoma. The challenge that we encountered was to determine its origin, the possibilities being divergent differentiation from adenocarcinoma post radiation therapy, de novo neoplasm or urothelial carcinoma with extensive squamous differentiation. Our literature review showed also that the etiology of prostatic squamous carcinoma is still unclear. We present our approach in an attempt to solve this dilemma.

“…[41][42][43][44][45][46][47] It has been reported in the setting of Schistosomiasis infection. 48 Suggested criteria for a diagnosis of squamous cell carcinoma of the prostate include (i) the presence of unequivocal features of malignancy, (ii) the presence of definitive squamous differentiation, (iii) lack of a conventional carcinoma component, (iv) no prior treatment with radiation or hormones and (v) no squamous cell carcinoma elsewhere.…”

The vast majority of prostatic tumors developing in adult males are adenocarcinomas. For the most part, variations in histology have not received specific designations and, from a practical approach, have had any specific prognostic implications handled through application of the Gleason grading system. Nonetheless, some of the adenocarcinoma variants have specific clinical features and differential diagnoses. Furthermore, there has been some controversy regarding the appropriate application of the Gleason grading scheme in these tumors. In addition, there are carcinomas that are in fact not adenocarcinomas and that should be kept as distinct entities. In this paper, the histologic variants of adenocarcinoma are reviewed with emphasis on clinicopathologic features and the clinical relevance of these subtypes. Other carcinomas that occur in the prostate gland are also discussed again with a focus on the clinicopathologic characteristics.

Primary squamous cell carcinoma of the prostate (PSCC) is a rare disorder affecting the prostate forming 0.5% of prostate malignancies. Due to rarity of presentation there are many dilemmas regarding the clinical features, investigation and the best option in the management of PSCC. Here we studied 2 cases of PSCC retrospectively regarding the common clinical presentation, the investigations to prove the diagnosis and treatment of the patient by radiotherapy as the primary treatment. We reviewed the previous published literature about PSCC to ascertain the best treatment option based on the stage of the disease.
