Mohs micrographic technique in high-risk basal cell carcinoma: a 3D prediction of safety margins.

Objective: Compared with standard excision with a two-dimensional histological examination, Mohs micrographic surgery offers a lower recurrence rate and a greater extent of healthy tissue sparing for the treatment of high-risk basal cell carcinoma (BCC). The aims of this study were to first quantify the healthy tissue spared through the micrographic technique compared to traditional surgery for high-risk tumours. Then, to speculate, through the analysis of the distal micrographic resection margin, the adequate width of safety margins for standard excision.

Purse-string suture versus full-thickness skin graft: An efficacy and safety comparison study.

Purse-string suture (PSS) and full-thickness skin graft (FTSG) are two different approaches to the closure of circular skin defects. In this study, we compare the feasibility and the aesthetic outcome of these two techniques in high operatory risk non-melanoma skin cancer (NMSC) patients. We performed a retrospective study on 65 patients, treated with PSS or FTSG, and evaluated after a minimum follow-up of 6 months.

Minced Skin Grafting: A Minimally Invasive and Low-Cost Procedure to Treat Pyoderma Gangrenosum.

Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis that usually presents as a painful ulcer with erythematous and undermined borders and is often characterized by pathergy. Although this condition precludes a surgical approach, in cases resistant to treatment with immunosuppressive agents, skin grafts and amputation are considered last resorts. Both expose the patient to the risk of developing new lesions.

The impact of COVID-19 pandemics on dermatologic surgery: real-life data from the Italian Red-Zone.

Background: The COVID-19 pandemic is challenging healthcare systems worldwide. Dermatology had to re-prioritize visits, guarantee urgent care, and ensure continuity for chronic patients.

Objectives: To evaluate the COVID-19 impact on dermatologic surgery outpatient management.

Safety margins for dermatofibrosarcoma protuberans: a comparison between wide local excision and Mohs Tubingen technique.

Background: Dermatofibrosarcoma protuberans (DFSP) is a rare, locally infiltrating, rarely metastasizing, soft tissue tumour. Due to its indistinct margins, local aggressive behaviour and high recurrence rate, the surgical approach is complex. Micrographic surgery and variants of this technique, e.

Eradication of basal cell carcinoma of the head and neck using the surgical excision with a new stained margin technique: a preliminary study.

Background: Basal cell carcinomas (BCCs) are common cutaneous neoplasms that mainly affect fair-skinned subjects, in sun-exposed areas of the body. The treatment of choice of BCCs is represented by surgical excision and different techniques are available, in order to allow the complete eradication of the tumor with the best cosmetic results. In this paper, we describe the surgical excision with stained margin technique (SMET) and we report its efficacy for the treatment of BCCs of the head and neck region.

Insights into the use of gadolinium and gadolinium/boron-based agents in imaging-guided neutron capture therapy applications.

Gadolinium neutron capture therapy (Gd-NCT) is currently under development as an alternative approach for cancer therapy. All of the clinical experience to date with NCT is done with (10)B, known as boron neutron capture therapy (BNCT), a binary treatment combining neutron irradiation with the delivery of boron-containing compounds to tumors. Currently, the use of Gd for NCT has been getting more attention because of its highest neutron cross-section.

Extemporaneous transposition flap for closing two contiguous surgical excision.

The authors present a surgical procedure to remove two contiguous cutaneous lesions using a single transposition flap and suture line without an evident scar. This method is useful when rhomboid surgical exeresis could not represent the best choice to obtain an optimum aesthetic result.

Basal Cell Carcinoma of the Nipple in a Male Patient: A Particular Case Report.

Basal cell carcinoma (BCC) is a common skin cancer worldwide. However, BCC of the nipple and areola complex is rare. Men are more affected than women.

The hydroboration reaction as a key for a straightforward synthesis of new MRI-NCT agents.

In this study the hydroboration reaction has been exploited to produce in only four steps a new lipophilic GdBNCT/MRI agent (PB01). As a matter of fact, the formation of a new B–C bond to link the decaborane with the lipophilic moiety greatly simplifies the synthesis of PB01 with respect to the previously reported dual agents. The complexes obtained (PB01a and PB01b) have been fully characterised from the relaxometric point of view and, after disaggregation with HPβCD, both isomers display high affinity for low density lipoproteins (LDLs) that can be exploited as specific carriers of these therapeutic and diagnostic agents for tumour cells.

Reconstruction of scalp defects with exposed bone after surgical treatment of basal cell carcinoma: the use of a bilayer matrix wound dressing.

Treatment of scalp defects after tumor resection or traumatic events is a challenging problem. Large defects with loss of soft tissue down to the bone require complex reconstructive options, including tissue expansion, local and distal scalp flaps, and free split thickness skin graft. Nonetheless, these techniques are often disfiguring and are limited by the relatively poor elasticity and vascularity of scalp tissues after recurrent resection or previous irradiation.

Selective release of cytokines, chemokines, and growth factors by minced skin in vitro supports the effectiveness of autologous minced micrografts technique for chronic ulcer repair.

A new effective surgical procedure to repair chronic ulcers called minced micrografts technique has been recently reported. The technique consists in spreading a finely minced skin sample upon the wound bed. In this study, we investigate the in vitro release of cytokines (interleukin-6, tumor necrosis factor-α, interleukin-1α, and granulocyte-colony stimulating factor), chemokines (monocyte chemoattractant protein-1 and growth-related oncogene-α), and growth factors (platelet-derived growth factor, basic fibroblast growth factor, vascular endothelial growth factor, hepatocyte growth factor, and nerve growth factor) by minced (referred to as the minced sample) vs.

“Opposite semilunar” variant of Burow triangle in rotation and advancement flaps.

The Burow triangle is an expedient suitably conceived either to facilitate sliding of the flap and avoid folds due to differences in skin distension or to correct coaptation of 2 cutting edges with a different length. In some cases, the triangle cannot be drawn in the right position either because of a particular anatomic site, for example, in proximity to commissures and openings, or because it is contraindicated to avoid unwelcome scar lines. In these cases, a semilunar ablation opposite to the direction of Burow triangle could be a valuable alternative.
