Keywords: Goldilock, Mastectomy, Goldilocks mastectomy, Breast reconstruction, mamma reconstruction, Oncoplastic, Risk reducing mastectomy, breast cancer, cancer Authors: Nanja Gotland Sundstrup (MD), Pia Cajsa Leth Andersen (MD) Institution: Department of Plastic Surgery and Burns, Rigshospitalet, Copenhagen University Hospital, Denmark Abstract This case report describes the “Goldilocks procedure” as a technique used for primary breast reconstruction in a patient with prior bilateral c. mamma, treated with lumpectomy and radiotherapy. An implant-based reconstruction was not advised due to the radiotherapy, and she was reluctant to undergo larger scale autologous reconstruction. She was suggested the “goldielocks procedure” as an upgrade to the simple mastectomy which was her alternative consideration. the Goldilocks procedure has the advantage of achieving immediate formation of a small breast, while simultaneously establishing a favorable platform for potential delayed reconstruction with autologous fat grafting. Patient medical history The patient, a 67-year-old woman had a history of bilateral breast cancer: left-sided in 2016 and right-sided in 2023, treated with lumpectomy, and radiotherapy, with additional chemotherapy for the right-sided cancer. Further she was found to carry a pathogenic CHEK2 mutation. The patient underwent bilateral risk reducing mastectomy using the Goldilocks technique, with maximal preservation of the skin envelope and subcutaneous tissue (1). Compared with a simple mastectomy, this approach preserved a good shape and projection resulting in the formation of a small breast. Furthermore, the result provided a more favorable foundation for potential delayed breast reconstruction. The patient was planned for a reconstruction in terms of lipofilling, and mastopexy as well as nipple reconstruction. Before and After Patient examination The patient generally presented with good skin quality. Clinical examination revealed sequelae of prior br
BeforeAfterThe patient, a 67-year-old woman had a history of bilateral breast cancer: left-sided in 2016 and right-sided in 2023, treated with lumpectomy, and radiotherapy, with additional chemotherapy for the right-sided cancer.

Compared with a simple mastectomy, this approach preserved a good shape and projection resulting in the formation of a small breast. Furthermore, the result provided a more favorable foundation for potential delayed breast reconstruction. The patient was planned for a reconstruction in terms of lipofilling, and mastopexy as well as nipple reconstruction.
Preoperative markings were performed with the patient upright. The upper breast border, breast footprint, and the inframammary fold (IMF) were delineated, and the median marked from the upper breast boarder extending inferiorly. The planned neo-papilla position was placed on the meridian 8 cm inferior to the upper breast border, with an additional reference point 10 cm lateral to the thoracic midline beneath the breast. As the mastectomy included excision of the native NAC, periareolar incision lines were used.
The subcutaneous mastectomy was performed, resulting in well perfused skin envelopes bilaterally. The hyperpigmentation of the skin is residual from the radiotherapy.
2
The skin was folded to preserve the maximal amount of tissue for de-epithelialization and temporarily secured with staples. The area designated for de-epithelialization was marked from the point of the planned neopapilla 8 cm below the upper breast border at the breast meridian, extending to the inframammary fold (IMF).
3
The breast was stuffed with napkins to help stretching the skin for easy de-epithelization.
4
5
An incision was made through the dermis and subcutaneous tissue along the medial line vertically and horizontally through the inframammary fold.
6
Skin perfusion was checked, to secure vital skinflaps by using fluorescence imaging.
7
The lateral excision line was adjusted to the medial side, leading to a marking at 10 cm distally from the top of the vertical line. From this point, a horizontal line was drawn toward the inframmary fold, following a wise-pattern design, to guide further de-epithelialization.
8
When satisfied with the tension of the skin the vertical incisions were closed.
9
A drain was installed and the horizontal line closed. All sutures were biosyn 4-0, an absorbable suture.
10
At one-year postoperative follow-up, the patient have had one time lipofilling and she is scheduled for a second lipofilling and mastopexy/ nipple reconstruction.
11
• Drains were removed 2 days postoperatively, once the output was serous and less than 30 mL per 24 hours.
• The patient was instructed to wear a surgical bra continuously (day and night) for the first 3 weeks, followed by daytime use for the subsequent 3 weeks.
• A follow-up evaluation with the operating surgeon were scheduled at three months to assess the long-term aesthetic outcome and determine the need for potential secondary autologous fat grafting.

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
Case 22 2026: Superior Gluteal vessel: A rarely used recipient for free flap reconstruction of lumbosacral defects: a case report.

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
