Benign and low-grade fibroepithelial neoplasms of the breast have low recurrence rate after positive surgical margins.

Breast phyllodes tumors are uncommon fibroepithelial neoplasms with a range of histologic features. Surgical excision is the primary management, but the need for excision to negative margins in benign and borderline phyllodes tumors is unclear. Here, we review the surgical management patterns and outcomes of 90 patients with benign and low-grade fibroepithelial lesions of the breast treated at our institution, including 19 borderline phyllodes tumors, 52 benign phyllodes tumors, and 19 representative neoplasms with overlapping features of fibroadenoma and benign phyllodes tumors, which were classified as 'fibroadenomas with phyllodal features'. In total, 52 (58%) had positive surgical margins on first excision, and of these 17 (33%) underwent re-excision to achieve negative margins. Residual tumor was identified in three (18%) re-excisions. Patients with fibroadenoma with phyllodal features were more likely to have a positive surgical margin than with benign phyllodes tumors or borderline phyllodes tumors (89 vs 49%, P=0.0015), and were less likely to undergo re-excision for positive margins (12 vs 43%, P=0.031). In total, there were three recurrences (3%), with one per fibroadenoma with phyllodal features, benign phyllodes tumor, and borderline phyllodes tumor. There was no statistically significant difference in recurrence rates between patients with positive or negative margins, or between patients with positive margin with or without re-excision. The extent of the positive margin did not predict recurrence. In conclusion, the recurrence rate of benign and low-grade fibroepithelial lesions is low and not associated with the original margin status. Patients with fibroadenomas with phyllodal features, benign phyllodes tumors, or selected borderline phyllodes tumors and positive margins on initial excision may be managed conservatively, with close follow-up and timely re-excision of any potential recurrence.

Pólipo ureteral fibroepitelial. Revisión de la literatura / Fibroepithelial ureteral polyp. Review of the literature

Los pólipos fibroepiteliales (PF) del uréter son poco frecuentes para plantear un serio problema de diagnóstico diferencial con el carcinoma urotelial. Entre ambos existen algunas diferencias radiológicas pero no siempre es fácil reconocerlas. Históricamente, se ha realizado nefroureterectomia innecesariamente en muchos casos de pólipos. Con el avance de la instrumentación, la ureterorrenoscopia es una prueba de gran utilidad para el diagnóstico de los defectos de repleción ureteral. La biopsia confirma el diagnóstico. Los PF que provocan obstrucción del tracto urinario superior precisan de tratamiento endourológico o laparoscópico (AU)

Fibroepithelial polyps (FP) of the ureter are infrequent benign tumors often not easily distinguished from malignant transitional-cell carcinomas by radiologic means. Historically, many patients have undergone unnecessary nephroureterectomy for these lesions. With the advancement in endourologic instrumentation, the ureteroscopy is the gold standard of diagnosis for ureteral filling defect. When FP causes upper urinary tract obstruction can be treated with endourology or laparosocopy (AU)

Polyps and masses of the pediatric urinary bladder: a 21-year pathology review.

Although not uncommon in adults, bladder tumors are rare in children. In addition, the histologic types of tumors seen in the pediatric population differ from those seen in adults. Although rhabdomyosarcoma is the most common pediatric bladder tumor, many other benign, malignant, and reactive lesions can be encountered. All may present clinically as a mass or polyp in the bladder. This study was designed to describe the pathology and patient demographics of pediatric bladder masses, because there are few studies describing these entities. Retrospectively reviewing our experience over a 21-year period, we identified 98 specimens from 65 patients with polyps or masses in the urinary bladder. As expected, the most frequent diagnosis was rhabdomyosarcoma. This was followed by fibroepithelial polyp and a variety of additional nonurothelial tumors. Only 7 urothelial tumors were identified, including 1 low-grade papillary urothelial carcinoma. Inflammatory lesions, such as cystitis cystica and nephrogenic adenoma, were invariably associated with an irritating factor when a history was provided. Our findings emphasize that diagnoses made in the pediatric urinary bladder are distinct from those in adults, although a wide variety of lesions may still be seen.

Genito-urinary polyps: summary of the 10-year experiences of a single institute.

OBJECTIVE: We present a large series of polyps situated in various parts of the urinary tract in adults, including 12 cases of fibroepithelial polyps, four cases of eosinophilic cystitis, three cases of benign prostatic epithelial polyp, and one case of transitional cell carcinoma presenting as a bladder polyp. MATERIAL AND METHODS: Data on 23 patients with polyps in the urinary tract treated in our department from December 1995 to December 2005 were reviewed. The characteristics of the patients, disease, and treatment modalities were recorded. RESULTS: Of the 23 patients treated in our institute during the study period, seven had polyps in the ureter, eight had polyps in the bladder, and eight had polyps in the urethra. Twenty-one patients underwent endoscopic resection of the polyps, and two patients were managed conservatively with medical therapy. Twenty-two polyps were benign (fibroepithelial polyps, benign prostatic epithelial proliferations, eosinophilic cystitis), and in one patient transitional cell carcinoma presented as a bladder polyp. Postoperative recovery was excellent. Mild hematuria manifested in two patients during the perioperative period, but there was no recurrence in the follow-up period. Two patients with a urethral polyp managed with endoscopic resection developed urethral stricture during the postoperative period and required repeated urethral dilatations during the follow-up period. CONCLUSION: The presence of polyps in the urinary tract is rare. The treatment of choice is endoscopic resection, and the prognosis of these patients is excellent.

Dermoscopy patterns of fibroepithelioma of pinkus.

BACKGROUND: Fibroepithelioma of Pinkus (FeP) is a rare variant of basal cell carcinoma that may clinically mimic a number of benign skin tumors. While the dermoscopic features of basal cell carcinoma have been studied extensively, little is known about the dermoscopic features of FeP. OBSERVATIONS: Retrospective evaluation of clinical records and digital clinical dermoscopic images of 10 histopathologically proved FePs (6 nonpigmented and 4 pigmented) was performed. Clinically, no FeP was correctly identified and, in half of all patients, a clinical differential diagnosis of purely benign skin lesions was made. Dermoscopy enabled the correct diagnosis in 9 of 10 FePs, based on the presence of fine arborizing vessels, either alone or associated with dotted vessels, and white streaks (in 100%, 70%, and 90% of lesions, respectively). In the 4 pigmented FePs, a structureless gray-brown area of pigmentation and variable numbers of gray-blue dots were observed, in addition. CONCLUSIONS: Dermoscopy is helpful in diagnosing FeP and in differentiating this variant of basal cell carcinoma from other benign skin tumors commonly included in the clinical differential diagnosis. This presumes, however, that dermoscopy is used as a first-line examination for all skin lesions, not only for those that are clinically suspect.
