The incidence of squamous cell carcinoma of prostate is between 0.5-1% of all neoplastic lesions of this gland.
Due to their rarity, there are no protocolised recommendations on the management of these patients. A report is presented on a patient with this diagnosis treated at our institution, its outcome at two years of follow-up, and a review of the subject.
Case report: Male patient, 79 years old, diagnosed with invasive squamous cell carcinoma of the prostate. Staged as T4NxMx/IPSA 2.64/Gleason undeterminable.Work up studies were negative, and primaries from nearby organs were ruled out.
He was treated with radiotherapy as monotherapy and was scheduled for an intensitymodulated radiotherapy (IMRT) technique, initially to the pelvis at a radiotherapy dose of 46 Gy 2Gy daily (PTV 1), further reinforcing prostate and vesicles up to 56 Gy (1.1 PTV), and finally to 76 Gy to prostate (PTV 1,1,1).
With a follow-up of two years, lung lesions were found, which were biopsied and positive for squamous cell carcinoma.
