Breast reconstruction after nipple sparing mastectomy (NSM) plays, nowadays, a fundamental role in breast cancer management. There is no consensus on the best implant-based reconstruction technique, considering 2 stages (expander-prosthesis) or direct-to-implant (DTI). A retrospective review of consecutive adult female patients who underwent NSM with breast reconstruction over a 3-year period (January 2013 to December 2015) was performed. Patients were divided into 2 groups according to the type of reconstruction: expander/prosthesis (group A) and DTI (group B). Anamnestic data were collected. Number and type of procedures, complications and esthetic satisfaction were registered and compared. Fifty-six patients were included in group A (34.6%) and 106 in group B (65.4%). Complications associated with the 2 types of breast reconstruction were not different (P = 0.2). Patients in group A received a higher number of total surgical procedures (considering revisions, lipostructures and contralateral symmetrizations) than those in group B (2.5 ± 0.69 and 1.88 ± 1.02, P = 0.0001). Satisfaction with breast reconstruction resulted higher in group A (7.5 ± 2.6 and 6 ± 1.9, P = 0.0004). At the multivariate analysis, chemotherapy and radiotherapy were not correlated with complications, regardless of the group (odds ratio, 0.91 and 2.74, respectively). Radiotherapy and chemotherapy did not even influence the esthetic result, regardless of the group (P = 0.816 and P = 0.521, respectively). Prosthetic breast reconstructions, both in a single and in 2 stages, are welcomed by patients and have relatively low and almost equivalent complication rates, independent of other factors such as chemotherapy, radiotherapy, lymphadenectomy, smoking and age. In our experience, 2-stage breast reconstruction, although requiring more operations, is associated with a higher esthetic satisfaction. Patients who perform a DTI breast reconstruction after NSM should be informed of the high probability of surgical revision.

Background: Brooke–Spiegler syndrome is a rare autosomal dominant disorder characterized by the continuous development of multiple benign skin appendage tumors. It is treated usually by repeated standard surgery. Here, we present a case study where electrochemotherapy (ECT) with bleomycin was used as an effective alternative approach in treating advanced dermal cylindromatosis of the head and neck in a patient with Brooke–Spiegler syndrome. Patients and methods: A 45-year-old woman presented with multiple recurrent dermal cylindroma lesions on her scalp. Previous treatment consisted of several surgical excisions that resulted in psychological deterioration due to the formation of numerous scars and extensive alopecic areas. ECT was offered to provide tumor removal and disease control and to improve the patient’s quality of life. Results: The treatment was well tolerated, and a significant reduction in neoplastic tissue was achieved. Importantly, scalp skin condition significantly improved, regaining a fair follicular density on the margins. Conclusion: This report suggests the feasibility of bleomycin ECT as a less invasive alternative option for controlling multiple scalp cylindroma lesions with cosmetically acceptable results, and improving quality of life.

The Tumour Microenvironment (TME) is pivotal for melanoma progression and contributes to therapy resistance. While dermal cell involvement is well established, the role of epidermal cells remains less defined. To explore the contribution of Normal Human Keratinocytes (NHKs) to melanoma biology, we investigated the modification of gene and protein expression of NHKs exposed to melanoma-conditioned medium or maintained in a co-culture system. The analysis focused on pathways related to proliferation, inflammation, Extracellular Matrix (ECM) remodelling, and cell adhesion. Due to the well-documented melanoma–fibroblast crosstalk, Normal Human Fibroblasts (NHFs) and Cancer-Associated Fibroblasts (CAFs) were used as comparative references. Keratinocyte gene expression changes under the influence of melanoma secretome only partially overlapped with those of NHFs and CAFs, indicating cell-type-specific responses. Exposure to melanoma-conditioned medium induced the upregulation of bFGF, CXCL-16, TIMP-2, and E-cadherin in NHKs, alongside downregulating TGF-β and MMP-9. Although bFGF is a recognized pro-tumorigenic factor, the modulation of CXCL-16, TIMP-2, and TGF-β may reflect a protective response. Notably, under co-culture conditions, NHKs exhibited a pronounced pro-inflammatory and ECM-remodelling phenotype, characterized by elevated production of cytokines (IL-1α, IL-1β, and IL-8) and ECM-degrading enzymes (MMP-7, 9, 12, and 13), indicative of a pro-tumoral feature. Collectively, these findings underscore an active role for NHKs in melanoma initiation and progression.

Background: Sentinel lymph node (SLN) biopsy in cutaneous melanoma patients evaluates the regional draining basin for occult micrometastatic disease. Occasionally, nonidentification of SLN impairs the acquisition of this important prognostic factor. Objectives: To investigate the outcomes of melanoma patients with negative lymphoscintigraphic findings and patients who underwent SLN biopsy from 2004 to 2015 (n = 1200) were retrospectively reviewed for tumor characteristics and clinical outcomes. Methods: Patients with nonvisualized lymph nodes (NV group) who underwent only preoperative lymphoscintigraphy were separated and compared with a cohort drawn from all melanoma patients who completed the surgical procedure within the same period (V group). Results: A negative lymphoscintigraphic scan was observed in 38 cases (3.2% of all patients). The NV group showed a significantly older age (median 66.0 vs. 48.3 years; P < 0.0001). Head and neck melanomas were more frequent in the NV group compared to the control group (25.1 vs. 7.8%; P = 0.009). Tumor characteristics such as ulceration and Breslow thickness do not influence the lymphoscintigraphy result. No differences were found in overall survival (OS) and disease-free survival (DFS) between the groups. Conclusions: The nonvisualization of regional lymph nodes by lymphoscintigraphy is more frequent in older patients with head and neck melanomas. From the clinical point of view, no specific recommendation emerged for patients’ management because the nonvisualization of the SLN did not show a significant influence on DFS and OS rates. However, lack of knowledge of lymph node status suggests performing a tighter follow-up eventually by ultrasound evaluation of all potential lymph node drainage basins.

Background: The reconstruction of extensive full-thickness lower eyelid defects constitutes a challenge for plastic surgeons. Various techniques have been described to cater to patients’ specific defect needs, with the aim of achieving the best results. Materials and Methods: We performed a retrospective observational study assessing our experience with a combination of a single-stage procedure consisting of a hard palate graft and a Fricke flap for patients with complex lower lid resections undergoing immediate total reconstruction at our institution. Clinical data, histological type and results, size of tumor, recurrences, and post-operative complications were collected to evaluate outcomes. A Visual Analogue 10-point scale was administered to all patients to assess esthetic and functional outcomes. Results: Seven lower lid reconstructions were performed, with all patients receiving immediate reconstruction. The age of the patients ranged from 55 to 82. Five skin cancers were located on the right side and three on the left side. In all cases, histological diagnosis was non-melanoma skin cancers. The mean size of the tumor was 1.7 × 1.7. In all patients, negative surgical margins were obtained. All patients underwent 24-month follow up. No immediate complication from surgery was recorded within the first 30 days. During follow-up, lower lid ectropion was observed in one patient due to the development of a retracting scar. No local cancer recurrence or nodal metastasis were detected until 2 years follow-up. In only one case, adjuvant therapy was required. The aesthetic results were deemed satisfactory by all patients. Conclusions: According to our experience, the combination of a Fricke flap and hard palate graft is an excellent option for total lower eyelid reconstruction, with low morbidity and favorable outcomes, even in elderly and frail patients where satisfactory results were achieved in a single-stage procedure and short operative times.
