Purpose: This study evaluated the long-term clinical outcomes of silicone tube intubation using a Nunchaku® (FCI Ophthalmics Inc., Pembroke, MA, USA) tube in adult patients with epiphora. Methods: A prospective study was conducted on 42 eyes in 32 patients who underwent silicone tube intubation with a Nunchaku® tube between March 2023 and September 2023. Clinical manifestations, Munk scale scores, lacrimal syringing test results, and tear meniscus height were assessed before and after surgery. Surgical success was defined as a Munk score of ≤ 1. Results: The mean age of the participants was 56.2 years. Preoperative lacrimal irrigation testing revealed partial obstruction in 29 eyes (69.0%), patent passage in 11 eyes (26.2%), and punctal stenosis in 2 eyes (4.76%). The mean operative time was 6.4 minutes for monocular procedures and 9.7 minutes for binocular procedures. At three months postoperatively, 33 eyes (78.6%) in 28 patients achieved a Munk scale score of ≤ 1. No significant differences were observed between the surgical success and failure groups in terms of preoperative Munk scale scores, lacrimal syringing test results, or tear meniscus height. One patient who underwent binocular surgery experienced worsening symptoms in both eyes postoperatively with associated punctal inflammation and granuloma formation necessitating early silicone tube removal. Slit punctum was observed in 17 eyes across 11 patients, six of whom underwent a snip procedure during surgery. Conclusions Silicone tube intubation using the Nunchaku-style tube is a relatively simple and effective treatment for nasolacrimal duct obstruction. However, an increased incidence of lacrimal punctum-related complications was observed compared to previous studies, indicating the need for caution when performing the snip procedure concurrently.

Objective: To investigate whether breast tissue composition on preoperative automated breast ultrasound (ABUS) is associated with the accuracy of cancer multiplicity evaluation and postoperative recurrence-free survival (RFS) in patients with early-stage breast cancer. Materials and Methods: This retrospective analysis included women with early-stage breast cancer (clinical Tis, T1–2/N0) who underwent ABUS and digital mammography (DM) between October 2019 and April 2021. Tissue composition on ABUS was assessed using the Breast Imaging Reporting and Data System background echotexture (BE) (homogeneous-fat, homogeneous-fibroglandular, or heterogeneous). In a subgroup of patients with mammographically dense breasts, the glandular tissue component (GTC) on ABUS were further stratified into high (moderate or marked) or low (minimal or mild).Multivariable logistic and Cox regression analyses were used to identify factors associated with accurate cancer multiplicity categorization (unifocal, multifocal/multicentric, or bilateral) using ABUS + DM, and with RFS, respectively. Results: Among 409 women (mean age ± standard deviation, 50.2 ± 8.7 years), ABUS combined with DM yielded accurate cancer multiplicity categorization in 368 patients (90.0%). Neither BE nor GTC on ABUS affected the accuracy of categorization when ABUS was combined with DM. Over a median postoperative follow-up of 3.5 years, 11 recurrences occurred. Heterogeneous BE on ABUS (hazard ratio [HR] 11.24 [95% confidence interval [CI]: 2.82–44.92]; P = 0.001), BRCA mutation (HR 15.94 [2.47–102.97]; P = 0.004), and pathologic index cancer size (HR per 1-cm increase 1.91 [1.13–3.23];P = 0.02) was independently associated with RFS. In patients with dense breasts, heterogeneous BE (HR 14.17 [95% CI:2.69–74.60]; P = 0.002) and high GTC (HR 10.32 [2.35–45.28]; P = 0.002) on ABUS, BRCA mutation (HR 24.34 [2.75– 215.06]; P = 0.004), and pathologic cancer size (HR per 1-cm increase 2.62 [1.50–4.59]; P = 0.001) was independently associated with RFS. Conclusion In patients with early-stage breast cancer, heterogeneous BE and high GTC on preoperative ABUS, along with larger cancer size and BRCA mutation, was associated with worse RFS. However, BE and GTC did not affect cancer multiplicity evaluation when ABUS was used in combination with DM.

Objective: To evaluate the performance of supplemental automated breast ultrasound (ABUS) added to mammography-based breast cancer screening for women with nondense breasts. Materials and Methods: A retrospective search of radiology databases at two tertiary institutions identified asymptomatic women with nondense breasts who underwent breast cancer screening using both digital mammography (DM) and supplemental ABUS between January 2020 and December 2023. We excluded women without sufficient follow-up data or those without an established final diagnosis, including histopathologic results. The performance measures of DM alone and ABUS combined with DM (ABUS plus DM) were compared. The primary outcome was the cancer detection rate (CDR), and the secondary outcomes were sensitivity and specificity. Subgroup analyses were performed for women with scattered fibroglandular density and almost entirely fatty breasts. Results: A total of 2,904 pairs of screening examinations were performed in 1,683 women (59 ± 10 years), detecting 26 cancers. In comparison with DM alone, ABUS plus DM showed higher CDR (9.0 vs. 7.9 per 1,000 examinations, P < 0.001), higher sensitivity (100% [26/26] vs. 88.5% [23/26], P < 0.001), and lower specificity (95.0% [2,735/2,878] vs. 97.9% [2,817/2,878], P < 0.001). In women with scattered fibroglandular density, ABUS increased the CDR from 7.4 to 8.5 per 1,000 examinations and improved the sensitivity from 87.0% [20/23] to 100% [23/23] (P < 0.001). In women with almost entirely fatty breasts, ABUS plus DM showed the same CDR (16.4 per 1,000 examinations) and sensitivity (100% [3/3]) as DM alone. Three cancers (11.5% [3/26]), all of which were stage T1N0, were detected only by supplemental ABUS. Conclusion Supplemental ABUS improved cancer detection and sensitivity in women with nondense breasts, with the benefits primarily observed in those with scattered fibroglandular density.

Background: Basal cell carcinomas (BCCs) are often misdiagnosed as benign lesions, leading to inappropriate laser ablation. Misidentification may cause delays in proper diagnosis and surgical intervention, potentially affecting patient outcomes. Objective: We investigated the percentage of patients with BCC who were inappropriately treated with laser ablation following the introduction of dermoscopic examination reimbursement and analyzed their clinical and histological characteristics. Methods: We retrospectively reviewed the data of 106 patients with histologically confirmed BCC after reimbursement for dermoscopic examinations was implemented. Results: Among the 106 patients pathologically diagnosed with BCC, 11 patients (10.4%) had a history of laser ablation after being misdiagnosed with a benign lesion. All patients had pigmented BCCs on their faces, with the cheeks and nose (36.4% each) being the most frequent sites of involvement. The mean time between laser treatment and hospital visits was 30.9 months, and six patients (54.5%) were diagnosed with BCC within 1∼5 years after laser ablation. Of the 11 patients, six were treated by dermatologists, two by non-dermatologists, and two by non-licensed personnel. Nine patients showed at least one classic dermoscopic pattern, and the most common dermoscopic finding was the presence of multiple blue/gray globules (7/10, 70.0%). No recurrence after wide excision was observed during the last follow-up. Conclusion Despite dermoscopic examination reimbursement, our findings indicate that approximately 10.0% of BCCs are still misdiagnosed as benign lesions, as reported in a previous study. Therefore, when a malignancy is suspected, dermoscopic examination and biopsy should be considered to ensure an accurate diagnosis and facilitate appropriate treatment.

Purpose: The study investigated whether incorporating magnetic resonance imaging (MRI) alongside ultrasonography (US) in the preoperative evaluation is associated with differing survival outcomes between male and female breast cancer patients in a matched analysis. Additionally, clinicopathological prognostic factors were analyzed. Methods: Between January 2005 and December 2020, 93 male and 28,191 female patients who underwent breast surgery were screened. Exact matching analysis was conducted for age, pathologic T and N stages, and molecular subtypes. The clinicopathological characteristics and preoperative imaging methods of the matched cohorts were reviewed. Disease-free survival (DFS) and overall survival (OS) were assessed using Kaplan-Meier analysis, and Cox proportional hazards regression analysis was used to identify prognostic factors. Results: A total of 328 breast cancer patients (61 men and 267 women) were included in the matched analysis. Male patients had worse DFS (10-year DFS, 70.6% vs. 89.2%; P=0.001) and OS (10-year OS, 64.4% vs. 96.3%; P<0.001) than female patients. The pathologic index cancer size (hazard ratio [HR], 2.013; 95% confidence interval [CI], 1.063 to 3.810; P=0.032) was associated with worse DFS, whereas there were no significant factors associated with OS. Adding MRI to US for preoperative evaluation was not associated with DFS (HR, 1.117; 95% CI, 0.223 to 5.583; P=0.893) or OS (HR, 1.529; 95% CI, 0.300 to 7.781; P=0.609) in male patients. Conclusion Adding breast MRI to US in the preoperative evaluation was not associated with survival outcomes in male breast cancer patients, and the pathologic index cancer size was associated with worse DFS.

Background: Primary cutaneous CD30+ lymphoproliferative disorders (pcCD30-LPDs) are a diseases with various clinical and prognostic characteristics. Objective: Increasing our knowledge of the clinical characteristics of pcCD30-LPDs and identifying potential prognostic variables in an Asian population. Methods: Clinicopathological features and survival data of pcCD30-LPD cases obtained from 22 hospitals in South Korea were examined. Results: A total of 413 cases of pcCD30-LPDs (lymphomatoid papulosis [LYP], n=237; primary cutaneous anaplastic large cell lymphoma [C-ALCL], n=176) were included. Ninety percent of LYP patients and roughly 50% of C-ALCL patients presented with multiple skin lesions. Both LYP and C-ALCL affected the lower limbs most frequently. Multiplicity and advanced T stage of LYP lesions were associated with a chronic course longer than 6 months. Clinical morphology with patch lesions and elevated serum lactate dehydrogenase were significantly associated with LPDs during follow-up in LYP patients. Extracutaneous involvement of C-ALCL occurred in 13.2% of patients. Lesions larger than 5 cm and increased serum lactate dehydrogenase were associated with a poor prognosis in C-ALCL. The survival of patients with C-ALCL was unaffected by the anatomical locations of skin lesions or other pathological factors. Conclusion The multiplicity or size of skin lesions was associated with a chronic course of LYP and survival among patients with C-ALCL.
