BeforeAfterA 56-year-old male patient presented to the urological emergency department with progressively increasing swelling and redness in the genital area. Following the diagnosis of Fournier gangrene, the patient underwent multiple radical necrosectomies, bilateral hemiscrotectomies, and surgical displacement of the testicles into femoral scrotal compartments. Septic symptoms and acute kidney failure necessitated intensive care monitoring for the first sixteen days postoperatively. Subsequently, a significant soft tissue defect (17 x 24 cm) in the inguinal and genital region emerged, prompting referral to our hospital for specialized defect reconstruction. The patient's medical history revealed several underlying conditions including coronary artery disease, arterial hypertension, and type II diabetes mellitus with polyneuropathy. Initially, wound bed preparation was performed in our clinic for further reconstructive planning. It was noticed that the wound was suitable for split-thickness skin grafting. However, due to the patient's non-compliance and the necessity for postoperative bed rest, which the patient did not adhere to, the attempts at split-thickness skin grafting were futile on two occasions. Consequently, the patient decided to discharge himself voluntarily against explicit medical advice. Due to postoperative bleeding and persistent wound healing issues, the patient returned to our clinic for further surgical treatment.
The wound bed was prepared by debriding non-viable tissue and taking precise measurements of the defect. Split-thickness skin grafting was initially deemed suitable for the wound bed, and accordingly, the procedure was performed using skin harvested from the right thigh. However, due to the patient’s non-compliance with postoperative bed rest, which was crucial for successful healing, the skin grafting failed on two separate occasions.

The initial intraoperative plan was to raise a triangular-shaped bipedicled DIEP flap, intending to rotate it 90° clockwise to reconstruct the entire defect, encompassing both the testicles and scrotum
3
Reconstruction began with a thorough debridement of the wound edges. During this process, previously epithelialized skin areas resulting from the conducted split-thickness skin grafts were thourughly removed, even from the testicles.
4
Following a meticulous analysis of the flap dimensions and the extent of the defect, we revised our initial reconstruction plan. Considering the dimensions of the defect, we chose to perform proximal defect reconstruction using a sliding bipedicled DIEP (Deep Inferior Epigastric Perforator) flap for the proximal portion of the defect. Additionally, we decided to reconstruct the distal portions of the defect using rotational flap surgery from the inner thighs.
5
At the beginning, the borders of the rotational flap were delineated and marked on both sides of the thigh using a sterile marker. Following the preparation and elevation of the rotational flap, rotation was executed along with additional release in the form of bilateral Burow’s triangles. Through this method, the rotational flap successfully achieved tension-free coverage of the distal skin and soft tissue defect up to the base of the penis. The flaps were attached to the remaining scrotum with 3-0 absorbable sutures.
6
The borders of the DIEP flap were delineated and demarcated according to the needed size, using a sterile marker. For the reconstruction of the remaining defect, a DIEP flap reconstruction was performed, incorporating the robust medial perforators previously identified in the CT-Angiography. Initially, the right-sided DIEP flap was elevated from lateral to medial in an epifascial manner. Subsequently, the left-sided flap was then elevated
7
The procedure involved precise dissection of the large-caliber epigastric perforators of the medial row and tracking them through the muscle. The perforators were dissected until tensionless sliding of the flap was possible. In this process, the muscle remained almost entirely intact. Subsequently, the flap was perfused adequately only through the perforators after sufficient dissection.
8
Following the adequate preparation of the perforators, the flap was shifted distally.
9
Now, the tension-free caudal shift of the flap was performed. Furthermore, the umbilicus was repositioned more caudally. Limited mobilization of the abdominal wall was conducted to ensure a tension-free closure.
10Securing the DIEP flap and donor-site closure:Donor-site closure was achieved through a modified abdominoplasty. Securing of the flap was performed with self-resorbing subcutaneous and intracutaneous sutures. The abdominal fascia was closed with non-resorbale Prolene 2-0 sutures without constriction of the perforators on both sides.
The patient should remain sedentary in bed for five days with hourly monitoring of the perfusion of the flaps by the surgeon for 48 hours. The patient will require outpatient monitoring and follow-up appointments scheduled at two weeks, six weeks, three months, and 12 months post-surgery.

Case 20 2026: Staged Excision and Delayed Primary Closure of a large Nodular Basal Cell Carcinoma of the Anterior Scalp
Mikkel Halborg Sørensen, Nanja Gotland Sundstrup, Christian Lyngsaa Lang
Keywords: Basal cell carcinoma, scalp reconstruction, staged excision, primary closure, scalp biomechanics. Authors: Mikkel Halborg Sørensen, MD; Nanja Gotland Sundstrup, MD; Christian Lyngsaa Lang, MD. Institution: Department of Plastic Surgery and Burns, Rigshospitalet, Copenhagen University Hos-pital, Denmark Abstract A 48-year-old woman was referred with a non-radically excised nodular basal cell carcinoma of the anterior scalp complicated by wound infection and dehiscence. Re-excision with 3 mm margins to the galea was performed under local anesthesia. Given local inflammation and uncertain margin status, delayed reconstruction was planned pending histopathological confirmation. After clear margins were verified, controlled subgaleal undermining allowed tension-reduced primary closure. This staged strategy ensured oncologic safety while preserving hair-bearing scalp and avoiding unnecessary flap reconstruction. Patient medical history A 48-year-old woman was referred after incomplete excision of a nodular basal cell carcinoma (nBCC) of the anterior scalp performed in private plastic surgery practice. Histology demonstrated tumor involvement of the lateral margins, while the deep margin was free of tumor. Postoperatively, wound rupture and infection developed. Microbiology showed sparse growth of Staphylococcus aureus, and antibiotic therapy was initiated. The patient was otherwise non-smoking and healthy, with well-treated asthma, as her only relevant comorbidity. Before and After Patient examination Clinical examination revealed a 22 × 19 mm anterior scalp defect with limited perifocal erythema and minimal purulent discharge. No regional lymphadenopathy was palpable. Pre-operative considerations Initial histopathology demonstrated nodular basal cell carcinoma with focal lateral margin involvement and a clear deep margin, without perineural invasion or other high-risk features. In accordance with current recommendations for low-risk BCC, re-excision with 3 mm c

Keywords: Superior gluteal vessel, free flap reconstruction, lumbosacral defects Authors: 1. Tushar Dutta, Consultant Plastic Surgeon; 2. Arun PS, Consultant Surgical Oncologist; 3. Swati Sattavan, Consultant Surgical Oncologist; Institute: State Cancer Institute, Guwahati, Assam, India Abstract Lumbosacral defects that are too large for local flap reconstruction should be considered for microvascular free tissue transfer. However, lack of suitable recipient vessels in the area makes the task technically difficult. Options such as thoracodorsal and inferior gluteal vessels extended with vein grafts and AV loops have been described. Each option has its own drawbacks. Despite having a short course at its origin, the superior gluteal vessel is a viable alternative. We describe here a case where the vessel was dissected out with adequate length and used as a recipient for free flap reconstruction. Patient medical history The patient was a 41-year-old lady with no known comorbidities. She presented to us with a large lumbosacral mass that had been growing for one year. Before visiting our center, she had been operated twice at other institutions and had recurrences after each occasion. During the last three months the mass had started to grow rapidly and caused ulceration. There was no pain or fever. There was no neurological involvement of lower limbs. Patient had an ECOG status 1. Before and After Patient examination A 17x 22 cm mass was noted encompassing the left part of lumbosacral region and crossing the midline to the opposite side. The superior limit of the lesion was at the L3 vertebra and inferior extent was near the coccyx. Skin ulceration was noted at the center of the mass. On palpation, the mass was warm to touch, hard in consistency and immobile. Skin was fixed and fixity was also noted to the underlying muscle. No tenderness was elicited. Surrounding possible donor sites for flap harvest showed no scars. Pre-operative considerations Preoperative biopsy co
Case 23 2026: “Minimally Invasive Finger Amputation Using a Volar ‘Toilet seat’ Flap for Invasive Squamous Cell Carcinoma”
Claes Hannibal Killerich, Nikolaj Warming
Keywords: Squamous cell carcinoma; finger amputation; volar flap; local reconstruction; traction neurectomy; hand surgery. Authors: Claes Hannibal Killerich, Nikolaj Warming Abstract A 93-year-old woman presented with a chronic non-healing dorsal finger wound initially diagnosed as actinic keratosis. Repeat biopsy revealed invasive squamous cell carcinoma with joint and bone involvement. Due to the extent of invasion, distal amputation of the third finger was required. Reconstruction was performed using a volar “toilet seat” flap under digital nerve block to minimize surgical burden. The procedure achieved clear margins, preserved stump length, and avoided donor-site morbidity. This case highlights the importance of early re-biopsy of non-healing lesions and adapting surgical strategy to patient age, function, and comorbidity. Patient medical history A 93-year-old woman presented with a wound on the dorsal aspect of the proximal phalanx of the left third finger. A primary biopsy revealed actinic keratosis, and the lesion was treated several times with curettage and electrodesiccation by a private dermatologist. Despite repeated treatments under professional supervision, the wound failed to heal.Due to the persistent non-healing nature of the lesion, a repeat biopsy was performed, confirming the diagnosis of squamous cell carcinoma (SCC). The patient was referred to the Department of Plastic Surgery, Aalborg University Hospital, where a primary excision was performed with a 7 mm surgical margin. Histopathological examination demonstrated invasive tumor growth involving both joint and bone. The defect was subsequently reconstructed using a full-thickness skin graft. Before and After Patient examination The left third finger showed a healed full-thickness skin graft on the dorsal aspect of the proximal phalanx, covering the proximal interphalangeal (PIP) joint. There was no visible residual tumor, and no palpable lymphadenopathy in the left cubital fossa or axillary re
