The combined approach of surgical resection along with superficial x-ray radiotherapy emerges as a superior treatment option for individuals with keloids, which hold huge potential for enhancing aesthetic outcomes and preventing keloid recurrence.

UNASSIGNED: Mohs micrographic surgery is a complex but essential aspect of functional and cosmetic skin cancer removal. It allows for skin cancers to be removed from cosmetically challenging areas in the most efficient and effective possible method; however, closure of these lesions can be difficult.
UNASSIGNED: An 80-year-old male presented for Mohs surgery of a basal cell carcinoma on the right nasal sidewall that measured 3.4 cm. The patient underwent seven stages of Mohs surgery, and the final defect measured 6.5 cm × 5.5 cm, resulting in a large area for closure with multiple cosmetic and functional units affected.
UNASSIGNED: This case discusses options for complex closure of large defects on the nose and the reasoning behind the final choice in closure.

(1) Background: The reconstruction of cutaneous defects following surgical procedures in the nasal pyramid presents a challenge due to the limited amount of available tissue. In cases of larger defects, skin from adjacent units is used. Traditionally, two-stage surgical flaps have been employed for reconstructing these defects. Tunnelized island flaps allow for the one-stage surgical reconstruction of nasal pyramid defects, using tissue from the forehead or cheek for the flap. (2) Methods: Descriptive retrospective study of 21 consecutive patients who underwent surgery for defects on the nasal pyramid using tunnelized island flaps. (3) Results: Surgical reconstruction was performed in 21 patients with basal cell carcinomas, 14 of them using the melolabial island flap and 7 using the paramedian forehead island flap. In all cases except one, clear histological margins were obtained. Immediate complications were mild and minor. It is worth noting the trapdoor effect complication, which improved over time in most cases, resulting in a satisfactory cosmetic outcome. No tumor recurrences were observed during an average follow-up period of 17.7 months. (4) Conclusions: Tunnelized island flaps allow for single-stage reconstruction of nasal pyramid defects, yielding excellent cosmetic results by utilizing adjacent skin. This procedure demands a certain level of skill but is associated with minimal complications, making it a valuable alternative in reconstructive dermatological surgery.

There is limited data on benefits of healing after Mohs surgery using porcine xenografts (PXs) compared to second intention (SI). This case series sought to describe healing time, scar size, cosmetic outcome, pain, and infection rates in patients treated with PX or SI for wounds on lower extremities. 14 patients were enrolled. Six patients received treatment with SI, and eight patients received PX. 11 patients (4 SI, 7 PX) completed follow-up visit after 3 months (79% follow-up rate) when primary outcome measure was assessed. 64% of patients took > 3 months to heal. 72% of patients healed within 6 months post-surgery. Scars contracted by > 50% in 7/11 patients completing follow-up. In SI group, 3/5 patients self-reported pain level > 1 out of 10 at 1-week post-surgery compared to 3/8 in the PX group. Two patients in each group developed post-operative wound infection and three patients in PX group experienced other adverse events. These results suggest that healing with PX or SI resulted in small scar size, low post-operative pain level, and low rate of adverse events. Both groups had longer healing times than expected.

Micrographic dermatologic surgery (MDS) recently became a board-certified field within dermatology with the first board examination administered in October 2021. To be eligible, dermatologists must have completed a fellowship through the Accreditation Council for Graduate Medical Education (ACGME) or attest to active practice of Mohs micrographic surgery. Attestation of active practice is available from 2021-2025, after which, those sitting for the certifying examination must demonstrate completion of an ACGME-accredited fellowship. This study aimed to compile demographic information on physicians who passed the MDS board certification examination. Medicare Mohs micrographic surgery case volume was compared between fellowship-trained and non-fellowship-trained physicians as well as between members and non-members of Mohs organizations. Names of physicians who passed the examination were accessed on the publicly available American Board of Dermatology website. The Medicare database was used to screen for Mohs surgery case numbers from 2019, and the American College of Mohs Surgery (ACMS) and American Society for Mohs Surgery (ASMS) physician finder tools were used to determine active membership. Physicians not in the Medicare database and those who completed an ACGME-accredited fellowship within the past three years were excluded from case volume analysis. 1673 dermatologists passed the first certifying examination. Medicare Mohs case volumes were compared for 1310 of these physicians. The median number (interquartile range (IQR)) of Mohs surgery cases was significantly higher for physicians who were ACMS/ACGME-fellowship-trained compared to those who were not (370 cases (IQR: 211-560) vs 138 cases (IQR: 37-284), p < 0.001). Members of ACMS and/or ASMS also performed a higher median number of cases compared to non-members (334 cases (IQR: 160-526) vs 95 cases (IQR: 6-246), p < 0.001). Given the 5-year window to take the MDS examination without having completed an ACMS/ACGME-accredited fellowship, more physicians without formal training may choose to become board certified. In addition, less dermatologists may choose to complete an ACMS/ACGME-accredited fellowship since it is not required for board certification. As more dermatologists become board certified in MDS, it may become important to assess for active practice of Mohs surgery and define proficiency metrics.

Dermatofibrosarcoma protuberans is an uncommon low-grade malignant tumor that can invade locally and rarely metastasize. Dermatofibrosarcoma protuberans has a high rate of local recurrence due to incomplete excision, especially in deep tissues. Morbidity is often related to multiple local recurrences and removal of excessive tissue with large, complex repairs. We present a case of incompletely excised dermatofibrosarcoma protuberans after initial wide local excision. We subsequently employed a \"deep\" vertical Mohs micrographic surgical technique to remove the remaining tumor while creating a flap with the tumor-free superficial portion to preserve tissue and avoid a complicated repair. The patient is tumor-free for 7 years.

Amyloidoma is defined as solitary, localized, tumor-like deposit of amyloid in diverse organs without evidence of systemic amyloidosis. Here we report the case of a 49-year-old male patient with a solitary amyloidoma of the skin seated on the left upper lip. Full medical examination showed no signs of systemic amyloidosis. The mass was removed surgically with tangential shave and so far no signs of recurrence have been found.
