Selected patients with transrectal ultrasound (TRUS)-guided biopsies containing Gleason score 3 + 4 = 7 prostate cancer (PCa) may be considered candidates for active surveillance (AS). The purpose of this study was to determine if there are features that predict PCa upstaging and/or upgrading after radical prostatectomy (RP) in patients with Gleason score 3 + 4 = 7 PCa diagnosed on TRUS-guided biopsies. We searched our institution's database for patients with Gleason score 3 + 4 = 7 PCa diagnosed on TRUS-guided biopsy who underwent subsequent RP between January 2010 and January 2015. Two blinded genitourinary pathologists independently reviewed and assessed the following on biopsies: (a) nuclear size, nucleolar size and distribution of macronucleoli of PCa, which were subjectively graded using a semi-quantitative scale from 1 to 3, and (b) PCa with cribriform morphology and the size of cribriform disease. Patient age, serum prostate-specific antigen (PSA) and PSA density (PSAD) were also recorded. The Gleason score and stage (presence or absence of organ-confined disease (OCD)) were retrieved from RP reports. Comparisons were performed between groups using the chi-square test and Spearman correlation. One hundred and four patients were identified to have met inclusion criteria. The mean age was 63 (±6.1) years. Mean PSA and PSAD at diagnosis were 7.5 (±4.2) and 0.25 (±0.15) ng/mL, respectively. Gleason scores were upgraded to greater than 3 + 4 = 7 in 26.9 % (28/104) of patients, and 44.2 % (46/104) of patients had no OCD after RP. There was no correlation between age, PSA, PSAD or percent of biopsies with Gleason pattern 4 for either Gleason score upgrading or absence of OCD at the time of RP (p > 0.05). Thirty patients had cribriform morphology on TRUS-guided biopsy of which 60 % (18/30) had no OCD at RP (p = 0.04) while 36.7 % (11/30) were upgraded to Gleason score ≥3 + 4 = 7 after RP (p = 0.15). There was no association between nuclear size, nucleolar size and/or distribution of macronucleoli with upgrading and/or absence of OCD (p > 0.05). The size of cribriform pattern was not associated with the absence of OCD (p = 0.43) or Gleason score upgrade (p = 0.28). A proportion of patients with Gleason score 3 + 4 = 7 PCa at needle biopsy do not have OCD or are upgraded to higher Gleason scores after RP. In our study, patients with Gleason score 3 + 4 = 7 PCa with the presence of cribriform pattern 4 had a significantly increased chance of being found to have no OCD at the time of RP. There were no clinical or pathologic parameters at the time of TRUS-guided biopsy that identified risk factors for Gleason score upgrading at RP in this study. Cribriform morphology detected on biopsy in patients with Gleason score 3 + 4 = 7 PCa is associated with tumour upstaging after RP and may be considered a contraindication to active surveillance.
Primary squamous cell carcinoma of the ovary is rare. Most cases represent malignant transformation of ovarian teratomas. Other cases are associated with preexisting Brenner tumor or ovarian endometriosis. We report a primary ovarian squamous cell carcinoma in a 40-year-old woman. The patient had recurrent high-grade intraepithelial neoplasia of the vulva (VIN) and recurrent high-grade cervical intraepithelial neoplasia (CIN). Human papilloma virus (HPV) DNA 16/18 was identified in an in situ and invasive carcinoma in the left ovary; CIN and VIN were identified with in situ hybridization with biotinylated DNA probes. Review of the literature revealed nine cases of primary ovarian squamous cell carcinoma not associated with a preexisting ovarian lesion. Three cases were not associated with CIN and occurred in women who ranged in age from 64 to 90 years and did not have carcinoma in situ component. Six cases were associated with CIN, had a carcinoma in situ, and occurred in younger women ranging from 33 to 54 of age. Our case belonged to the latter category. This report raises the possible causal relationship of HPV with primary ovarian squamous carcinoma in the group of middle-aged patients with CIN.
Renal neoplasms with certain unusual features should be investigated immunohistochemically to rule out the possibility of EAML. The frequency of adverse outcome is lower in EAML than in renal cell carcinoma.
We report a case of vascular myxolipoma of the spermatic cord occurring in a 32-year-old man. Clinically, the lesion was mobile and tender. Pathologically, the tumor was encapsulated and rubbery with a beige-yellow gelatinous cut surface. Microscopically, the lesion consisted of adipose tissue with extensive areas of myxoid change and an abundance of thin and thick-walled blood vessels. We consider this tumor a vascular type of myxolipoma and propose the term angiomyxolipoma. The lesion should be distinguished from liposarcoma and aggressive angiomyxoma, which have malignant or aggressive clinical course.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
