Bilateral and multifocal phyllodes tumours of the breast: A case report

Phyllodes tumours are rare breast neoplasms that present as painless breast masses. They are classified as benign, malignant and borderline. More rare presentations of these tumours include bilateral asynchronous disease and unilateral multifocal disease. Surgical excision with clear margins remains the treatment of choice for these tumours. The present case report is the first to be discussed in the literature. It describes a patient presenting with synchronous bilateral, multifocal breast phyllodes tumours who underwent immediate reconstruction with tissue expanders at the time of her mastectomies.     

Complications of presumed ocular tuberculosis

Acta Ophthalmol. 2010: 88: 905–909

Abstract.

Purpose: To determine the effect of steroid treatment on visual outcome and ocular complications in patients with presumed ocular tuberculosis. Methods: Retrospective review of patients with presumptive ocular tuberculosis. The clinical diagnosis was made based on ocular findings, positive purified protein derivative (PPD) testing of more than 15 mm induration, exclusion of other causes of uveitis and positive ocular response to anti‐tuberculous therapy (ATT) within 4 weeks. Group 1 included patients who had received oral prednisone or subtenon injection of triamcinolone acetonide prior to ATT. Group 2 included patients who did not receive corticosteroid therapy prior to administration of ATT. Results: Among 500 consecutive new cases of uveitis encountered in 1997–2007 there were 49 (10%) patients with presumed ocular tuberculosis. These comprised 28 (57%) male and 21 (43%) female patients with a mean age of 45 years (range 12–76 years). Four (20%) patients in group 1 had initial visual acuity of 20/40 or better, in comparison to eight (28%) patients in group 2. At 1‐year follow‐up, six (30%) patients in group 1 had a visual acuity of 20/40 or better compared with 20 (69%) patients in group 2 (p = 0.007). Of 20 eyes (26%) in group 1 that had visual acuity of < 20/50 at 1‐year follow up, 14 (70%) eyes developed severe chorioretinal lesion (p = 0.019). Conclusion: Early administration of corticosteroids without anti‐tuberculous therapy in presumed ocular tuberculosis may lead to poor visual outcome compared with patients who did not receive corticosteroids prior to presentation. Furthermore, the severity of chorioretinitis lesion in the group of patients given corticosteroid prior to ATT may account for the poor visual outcome.     

Cytologic features of proliferative breast disease: a study designed to minimize sampling error

BACKGROUND: Assessment of cytologic features that allow accurate classification of proliferative breast disease has been hampered by sampling errors when fine-needle aspirations have been compared with their corresponding histologic sections. METHODS: To allow for optimal cytohistologic correlation, 2 smears (1 hematoxylin and eosin-stained and 1 Diff-Quik-stained) were prepared from each of 98 breast biopsies without mass lesions and compared with the corresponding histologic sections of the scraped area. Each smear was reviewed in a blinded fashion and assessed for cellularity, background elements, cytoarchitectural features of cell groups, and nuclear features by 2 reviewers. Smears were then classified as nonproliferative breast disease (NPBD), proliferative breast disease without atypia (PBD) or with atypia (PBDA), or DCIS, based on review of the corresponding histologic sections. RESULTS: When comparing NPBD/PBD (n = 86) with PBDA/DCIS (n = 12), smears from PBDA/DCIS were significantly (by the Fisher exact test or Wilcoxon rank sum P values with adjustment for multiple comparisons) more likely to be cellular; contain single cells and necrosis; exhibit nuclear overlap and cytoplasmic vacuoles; have large nuclei, macronucleoli, pleomorphism, clumped chromatin, and hyperchromasia; and were less likely to have complex cell groups, monolayers, swirling, cohesion, and myoepithelial cells in epithelial sheets and the smear background. When NPBD (n = 53) and PBD (n = 33) were similarly compared, smears from PBD were more likely to exhibit larger and more complex cell groups, but they were otherwise similar to smears from NPBD. CONCLUSIONS: There are many cytologic features that will allow a distinction of NPBD/PBD from PBDA/DCIS, but relatively few that can aid in separating NPBD from PBD.
