Breast cancers (BCs) are solid tumors composed of heterogeneous tissues consisting of cancer cells and an ever-changing tumor microenvironment (TME). The TME includes, among other non-cancer cell types, immune cells influencing the immune context of cancer tissues. In particular, the cross talk of immune cells and their interactions with cancer cells dramatically influence BC dissemination, immunoediting, and the outcomes of cancer therapies. Tumor-infiltrating lymphocytes (TILs), tumor-associated macrophages (TAMs), and myeloid-derived suppressor cells (MDSCs) represent prominent immune cell populations of breast TMEs, and they have important roles in cancer immunoescape and dissemination. Therefore, in this article we review the features of TILs, TAMs, and MDSCs in BCs. Moreover, we highlight the mechanisms by which these immune cells remodel the immune TME and lead to breast cancer metastasis.

Basal cell carcinoma is the most common non-melanoma skin cancer of the nose. Defects of the nasal ala and tip region are among the most difficult to repair due to their intrinsic characteristics. To present our experience with the extended rotation flap for reconstruction of nasal ala defects and evaluate the outcome using the Patient and Observer Scar Assessment Scale (POSAS). Twenty-two patients with partial thickness nasal ala defects reconstructed using the extended rotation flap were assessed. Final cosmetic and functional outcomes were evaluated using the POSAS. Flaps survived in all the reported cases and no major complication was recorded. Histology showed complete excision of the tumour in all cases. Using the POSAS, the mean overall evaluation for patients was 1.8/10, while the mean overall evaluation for the evaluation panel was 2.2/ 10. Although similar flaps have been previously described, the extended rotation flap for nasal ala and tip reconstruction represents a functionally and cosmetically appealing wound closure option, respecting and avoiding any distortion of the alar crease.

Background: Abdominal wall endometriosis (AWE) is a rare pathological condition that mostly occurs in the post-cesarean section. This study aimed to describe the surgical approach employed in treating 31 patients at our center over the past decade and compare the outcomes with those reported in scientific literature. Methods: We retrospectively evaluated the data of 31 patients with a cesarean section history who underwent surgery for AWE excision between 1 November 2012, and 31 January 2023, at the University of Naples Federico II, Italy. Subsequently, we reviewed the scientific literature for all AWE-related studies published between 1 January 1995, and 31 July 2024. Results: Most women presented with a palpable abdominal mass (90.3%) at the previous surgical site associated with cyclic abdominal pain (80.6%) concomitant with menstruation. All patients underwent preoperative abdominal ultrasound and magnetic resonance imaging, 71% underwent computed tomography, and 32.2% received ultrasound-guided needle biopsies. Furthermore, 90.3% and 9.7% had previous Pfannenstiel and median vertical surgical incisions, respectively. All patients underwent laparotomic excision and abdominal wall reconstruction, with prosthetic reinforcement used in 73.5% of cases. No recurrent nodules were detected in any patient at the 12-month follow-up. Conclusions: AWE should be suspected in women with a history of cesarean section presenting with palpable, cyclically painful abdominal mass associated with the menstrual cycle. Preoperative ultrasound and magnetic resonance imaging are essential, and surgical excision must ensure clear margins. Abdominal wall reconstruction should include prosthetic reinforcement, except when the defect is minimal (≤1.5 cm). An ultrasound follow-up at 12 months is recommended to confirm the absence of recurrence.

Background: Esophageal achalasia is a rare motility disorder characterized by impaired lower esophageal sphincter (LES) relaxation and food stasis. Surgical interventions, including Heller myotomy with fundoplication or peroral endoscopic myotomy (POEM), effectively alleviate symptoms but induce significant anatomical and functional alterations. In various gastrointestinal surgeries, microbiota have been implicated in modulating clinical outcomes; however, their role in achalasia surgery remains unexplored. Methods: We performed a narrative literature search of various databases to identify studies exploring potential interactions between the gastroesophageal microbiota, achalasia pathophysiology, and surgical treatment, proposing clinical implications and future research avenues. Results: Chronic esophageal stasis in achalasia promotes local dysbiosis by facilitating aberrant bacterial colonization. Surgical restoration of esophageal motility and gastroesophageal transit induces substantial shifts in the microbial ecosystem. Analogous microbiota alterations following procedures such as fundoplication, gastrectomy, and bariatric surgery underscore the significant impact of mechanical modifications on microbial composition. Comprehensive microbiota profiling in patients with achalasia may enable the identification of dysbiotic phenotypes predisposed to complications, thereby providing personalized therapeutic interventions including probiotics, prebiotics, dietary modulation, or targeted antibiotic therapy. These insights hold promise for clinical benefits, including the mitigation of inflammation and infection, monitoring of surgical efficacy through microbial biomarkers, and optimization of postoperative nutritional strategies to reestablish microbial homeostasis, ultimately enhancing patient outcomes beyond conventional treatment paradigms. Conclusions: The gastroesophageal microbiota is a compelling mediator of surgical outcomes in achalasia. Future investigations integrating microbiological and inflammatory profiling are warranted to elucidate the functional role of the gastroesophageal microbiota and assess its potential as a biomarker and therapeutic target.

Squamous cell carcinoma is the most common cancer of the oral cavity, particularly of the tongue. Surgery is the treatment of choice, but it can have a dramatic impact on patients' quality of life. Although the primary goal of tongue reconstruction is the restoration of vital functions such as swallowing and speech, a good cosmetic result should also be achieved. Herein we present the case of a 54-year-old woman who underwent total glossectomy, describing and highlighting the advantages of our modified technique: the "Ghost-shaped" anterolateral thigh perforator flap.
