"Postoperative wound care in dermatologic surgery: update and narrative review".

Dermatologic surgery is associated with a very low risk of complications. There is no widely accepted, evidence-based protocol with recommendations for postoperative wound care after dermatologic surgery. In this narrative review, we will be discussing the evidence on surgical wound care products and procedures. Overall, we found relatively few studies and, in many cases, a lack of statistically significant differences, possibly because of the low rate of complications. We'll be discussing the evidence on when we should initiate wound care procedures and their frequency, the type of ointment and antiseptics that should be applied, and the type of dressings that should be used. Despite the very few studies available on postoperative wound care following dermatologic surgery, there is sufficient evidence as to not recommend the use of prophylactic topical antibiotics. We also analyze the currently available evidence on surgical wound care in special situations, such as management of skin grafts, partial skin graft donor sites, xenografts/biomembranes, and surgical wounds to the legs.

Wood's light in inflammatory and autoimmune dermatoses, infections and skin cancer. / Luz de Wood en dermatosis inflamatorias, autoinmunes, infecciones y cáncer cutáneo.

Wood's lamp (WL) is a useful, cost-effective, and easy-to-learn diagnostic tool. Despite its advantages, the use of WL among dermatologists is limited. In porokeratosis, the "diamond necklace" sign often reported is consistent with the white fluorescence of the hyperkeratotic scale. Subclinical morphea lesions are seen as well-defined dark macules. Among pigmentary disorders, the bluish fluorescence of vitiligo, increased contrast of epidermal melasma, and follicular-centered red fluorescence of progressive macular hypomelanosis stand out. Regarding skin infections, erythrasma is associated with a coral red fluorescence; tinea versicolor, with a yellow-green fluorescence; Pseudomonas aeuriginosa, with a green fluorescence; and scabies with a blue-white fluorescence in the acarine grooves. In skin cancer, WL has been used to outline the surgical margins of lentigo maligna and non-melanoma skin cancer, with variable results.

How Dermatologic Surgeons Decide to Proceed with Surgery for Nonmelanoma Skin Cancer When Site Identification is Initially Uncertain: A Nationwide, Multicenter, Prospective Study.

BACKGROUND: Few studies show how dermatologic surgeons manage problems with site identification. OBJECTIVE: To estimate frequency and characterize management of skin cancer treated by surgery when the anatomic location of the tumor is in question. METHODS: Nationwide, prospective, multi-site cohort study. RESULTS: Among 17,076 cases at 22 centers, 98 (0.60%) were lesions in question (LIQ) for which site identification was initially uncertain, with these more often in patients who were male, older, and biopsied more than 30 days ago. Surgeons employed on average 5.0 (95% CI: 4.61-5.39) additional techniques to confirm the site location, with common approaches including: re-checking available documentation (90 lesions, 92%); performing an expanded physical examination (89 lesions, 91%); and asking the patient to point using a mirror (61 lesions, 62%). In 15%, photographs were requested from the biopsying provider, and also in 15%, frozen section biopsies were obtained. In 10%, the referring physician was contacted. Eventually, surgeons succeeded in definitively identifying 82% (80/98) of initially uncertain sites, with the remaining 18% (18/98) postponed. Most postponed surgeries were at non-facial sites. LIMITATIONS: Sites were academic centers. CONCLUSIONS: When the anatomic location of the tumor is uncertain, dermatologic surgeons use multiple methods to identify the site, and sometimes cases are postponed.

Solitary Superficial Angiomyxoma in an Uncommon Location: A Case Report and Literature Review.

Superficial angiomyxoma (SAM) is a rare, benign, and slow-growing soft tissue tumor with a tendency for frequent local recurrence. Most SAMs are solitary and sporadic. However, multiple SAMs, particularly on the external ear or eyelids, may be the initial or only sign of the Carney complex, an autosomal dominant syndrome that impacts various organs, including the heart, breasts, and skin, and is linked to endocrine hyperactivity. To ensure an accurate diagnosis, a comprehensive patient interview, physical examination, and laboratory tests, including endocrine-specific markers and imaging studies, are essential. Due to the high risk of recurrence, especially in large, encapsulated lesions, complete surgical excision is the preferred treatment approach. We present a case of a 24-year-old female with SAM on the shoulder, review the relevant literature, and discuss the pathogenesis and appropriate management of such cases.

Rare Intravascular Involvement of Pleomorphic Dermal Sarcoma Seen During Mohs Micrographic Surgery.

Pleomorphic dermal sarcoma (PDS) and atypical fibroxanthoma (AFX) are rare mesenchymal tumors that share similar clinical, histological, and immunohistochemical characteristics. Careful histopathological examination of a biopsy specimen that includes subcutaneous fat remains the preferred way to differentiate between these tumors. AFX is limited to dermal invasion, whereas PDS demonstrates deeper invasion. Moreover, PDS may present with tumor necrosis and high-grade histological findings, such as lymphovascular and perineural invasion, features absent in AFX. However, like PDS, AFX is a diagnosis of exclusion, and an exhaustive immunohistochemistry panel is recommended to distinguish these tumors from other spindled cell tumors in the differential diagnosis. The authors present the case of an 86-year-old man with biopsy-suspected AFX who was referred for Mohs micrographic surgery for tumor excision. During Mohs, the tumor was observed to have invaded deeply into the subcutaneous tissue and galeal aponeurosis, aligning more closely with a PDS. The diagnosis of PDS was confirmed using en face processing during Mohs surgery, which captured the intravascular involvement of a solitary vessel. Differentiating between PDS and AFX is important because PDS is a more aggressive tumor, with a higher rate of local recurrence and metastasis, and requires closer monitoring.

The use of oral benzodiazepines for patient anxiety associated with Mohs micrographic surgery: An Australian survey.

A survey of Mohs surgery specialists in Australia showed diazepam was the preferred agent and felt to be the safest oral benzodiazepine for perioperative anxiolysis.

Comparison of Infection Rate Between Sterile and Nonsterile Gloves During Mohs Micrographic Surgery: An Updated Systematic Review and Meta-Analysis.

BACKGROUND: Mohs micrographic surgery (MMS) is a well-established technique for the removal of various types of skin cancers. While sterile gloves (SG) are commonly used in skin surgeries such as MMS, additional understanding of their effectiveness compared to nonsterile gloves (NSG) in preventing local infection is required. OBJECTIVE: We aimed to perform an updated systematic review and meta-analysis comparing the use of SG with NSG for local infection rate post-MMS and point out cost discrepancies between these 2 scenarios. METHODS: We searched MEDLINE, Embase, and Cochrane for studies published up to August 2023 comparing the use of SG with NSG during MMS that reported the outcome of wound infection. RESULTS: A total of 4 studies with 10,644 MMS were included, of which 7512 (70.6%) were performed with SG and 3132 (29.4%) were done with NSG. In the SG group, 232 out of 7512 cases (3.1%) developed infection compared to 64 out of 3132 (2.0%) in the NSG group [odds ratio (OR) 1.14; 95% confidence interval (CI) 0.85-1.52; P = .39; I2 = 0%]. Therefore, the post-MMS infection rates were not significantly different between SG and NSG groups, including in the excision (OR 0.92; 95% CI 0.48-1.79; P = .81; I2 = 0%) and reconstruction (OR 1.17; 95% CI 0.85-1.60; P = .34; I2 = 0%) subanalysis. Regarding the mean cost of the gloves, the NSG pair was $0.24, approximately 10% of the price of the SG pair ($2.27). CONCLUSION: The results support that, compared to SG, NSG are equally effective in preventing infections during MMS while offering significant cost savings without compromising patient outcomes.Protocol registration: PROSPERO, CRD42023458525.

Benefits and challenges of Mohs micrographic surgery for human papilloma virus-associated cutaneous malignancies: a systematic review.

Mohs micrographic surgery is the gold standard for treating many types of skin cancer, particularly skin cancers of high-risk areas such as the face, genitalia, and digits, due to its tissue-sparing technique and low recurrence rates. The use of Mohs micrographic surgery for human papilloma virus-associated cutaneous malignancies has yet to be explored in a systematic review. The authors sought to assess outcomes including recurrence rates of Mohs micrographic surgery for human papilloma virus-associated cutaneous malignancies. PubMed was searched for the use of Mohs micrographic surgery in types of human papilloma virus-associated cutaneous malignancies. After application of exclusion and inclusion criteria, 33 articles were included. 700 cases from 33 studies were included. Overall recurrence rate following Mohs micrographic surgery was 39/478 (8.2%) at a mean follow-up time of 51.5 months. Recurrence rate for nail unit/digit squamous cell carcinoma was 10/103 (9.7%) at mean follow-up of 47.6 months. Recurrence rate for penile squamous cell carcinoma was 15/181 (8.3%) at mean follow-up of 45.9 months. Recurrence rate for Bowen's disease in extragenital areas was 11/189 (5.9%) at mean follow-up of 59.7 months. Patients overall reported satisfactory functional and cosmetic results. Mohs micrographic surgery demonstrates low recurrence rates and excellent functional and cosmetic outcomes in the treatment of human papilloma virus-associated cutaneous malignancies.

Beyond the Surface: Chronic Lymphocytic Leukemia Diagnosis During Mohs Micrographic Surgery.

Chronic lymphocytic leukemia (CLL) is the most common type of leukemia in adults, characterized by the accumulation of abnormal lymphocytes in the blood and bone marrow. Its incidence increases with age, typically affecting older adults, with a median age at diagnosis around 70 years. CLL prevalence varies geographically, with higher rates observed in Western countries compared to Asian populations. Despite advancements in treatment, CLL remains an incurable disease, often managed through monitoring and therapy to control symptoms and slow disease progression. The purpose of this case report is to highlight two unique incidents of previously undiagnosed CLL, incidentally found during Mohs micrographic surgery (MMS). One case features a cutaneous squamous cell carcinoma in situ and the other a basal cell carcinoma. We present these cases to highlight the importance of diagnostic vigilance during Mohs histopathological processing. Diagnosis of CLL is typically through routine complete blood panels. However, these cases present unique initial presentations that warrant careful detection in medical practice. Detecting CLL during the examination of pathology samples from MMS excision may not be common practice, but its presence emphasizes the significance of thorough patient evaluation during medical procedures. This unexpected finding underscores the importance of thorough pathology examination during surgical procedures, highlighting the potential for detecting concurrent or underlying systemic conditions. Early identification of CLL in this context allows for prompt intervention and comprehensive management, emphasizing the necessity of integrated care approaches in medical practice.

A Surgical Conundrum: Addressing a Large Nasal Defect Following Mohs Micrographic Surgery.

Managing large nasal defects following Mohs surgery presents complex reconstructive challenges due to the nose's prominent and visible nature. These cases require a careful balance of preserving structural integrity, optimizing cosmetic outcomes, and maintaining vascular health. In situations where primary closure is impractical due to defect size and location, innovative techniques like the double rhomboid transposition flap offer versatile solutions, addressing both aesthetic concerns and functional requirements. The double rhomboid flap allows surgeons to achieve continuity of surrounding tissue, ensuring aesthetically pleasing texture, color, and thickness while minimizing complications like skin tension and potential airway issues. This case highlights the reconstructive challenges faced in managing large nasal defects following Mohs micrographic surgery for basal cell carcinoma. An 84-year-old male presented with a significant nasal defect following Mohs surgery that involved the dorsum, sidewall, tip, and ala, complicating primary closure due to skin tension and cosmetic concerns. Utilizing a double rhomboid transposition flap technique allowed for effective aesthetic and structural reconstruction, addressing skin tension and preserving nasal symmetry. This case emphasizes the importance of tailored reconstructive strategies to achieve optimal cosmetic and functional outcomes in complex nasal Mohs defects.

Adnexal Clear Cell Carcinoma Exhibiting Comedonecrosis of the Ear: A Rare Case Treated With Mohs Micrographic Surgery.

Adnexal clear cell carcinoma exhibiting comedonecrosis (ACCCC) is a rare, cutaneous, malignant neoplasm with limited reported cases since its discovery. ACCCC is characterized by unique clinical and histological features, demanding a precise diagnosis due to its potential for aggressive behavior and early metastases, distinct from other cutaneous tumors with clear cytoplasmic cells. We present the case of an 81-year-old male with a history of multiple non-melanoma skin cancers, who presented with a 5 mm erythematous papule on his left tragus. Initial tangential shave biopsy results were invasive clear cell squamous cell carcinoma that was moderately differentiated. Subsequent Mohs micrographic surgery (MMS) necessitating a full-thickness skin graft reconstruction was performed. Histopathological examination afterward confirmed ACCCC with pleomorphic epithelial cells, clear cytoplasm, and central comedonecrosis. Immunohistochemistry supported adnexal differentiation and squamous features. To our knowledge, this is the fifteenth reported case of ACCCC as well as the first documented case of ACCCC treated with MMS, offering a novel approach to managing this rare malignancy.

Store-and-Forward Teledermatology Wound Checks Following Mohs Surgery: A Pilot Study.

Introduction: Store-and-forward telemedicine is a form of electronic transmission in which patient images or clinical information are transmitted to clinicians for asynchronous clinical decision making. This study evaluated the use, feasibility, savings, and patient satisfaction of postoperative store-and-forward wound checks following Mohs surgery. Methods: Select patients were asked to participate in a virtual postoperative wound check after receiving Mohs surgery. Participants sent photos of their wound site and subsequently completed an anonymous survey. Results: One hundred and ten patients were enrolled, mean age 68 (range 32-87). Patients saved an average of $14.16, 78.6 miles of travel, and 90 min of travel time. Ninety-eight percent of respondents felt their quality of care in teledermatology was "about the same" to "much better" than compared with traditional in-person care. Sixty-four of the respondents (90.1%) reported they would prefer their next Mohs wound check to be conducted through teledermatology. Conclusion: Store-and-forward telemedicine in patients undergoing Mohs micrographic surgery is a safe, effective, and efficient method for postoperative wound care.
