RESUMO
Ideally, urgent dermatology referrals for evaluation of a lesion concerning for skin cancer should be triaged and processed with appropriate urgency by primary care and dermatology, respectively. We performed a retrospective single-institution study by conducting chart reviews of all dermatology referrals designated by primary care as urgent for evaluation of a lesion concerning for skin cancer. We identified 320 referrals placed between January 1 and December 31, 2018. Dermatology encounters for these patients occurred on or before 30 days for 50.6% of referrals and on or after 31 days for 38.4% of referrals, with 10.9% never completed. The percentage of all races excluding whites, non-Hispanic in the delayed appointment group (≥ 31 days) was 15.1% higher (95% CI 5.3-24.9) than in the timely appointment group (≤ 30 days). Similarly, the percentage of non-English languages in the delayed group was 7.1% higher (95% CI 0.5-13.7) than in the timely group. Overall, 15.8% of these referrals yielded diagnoses of malignancy, while 76.8% and 7.4% resulted in benign and pre-malignant diagnoses, respectively. The primary care team documented referral status (i.e., completed, incomplete, or pending) during their subsequent visits with the patients in only 37.5% of these referrals. Our findings demonstrate the need to improve the reliability of urgent referrals to ensure they occur in a timely manner with confirmation of "referral loop" closure at the referring clinician's end.

BACKGROUND: Traditionally, Mohs layers are excised using a beveled incision to facilitate tissue flattening for tangential sectioning. Some surgeons perform non-beveled incisions; however, these specimens may be harder for the histotechnician to process. Limited data exist comparing slide quality between these techniques. METHODS: Retrospective review of cases performed by two Mohs surgeons (surgeon 1 = non-beveled incision; surgeon 2 = beveled incision) using different incision angles between June 2014 and December 2016. Daily histopathologic slide quality assessment scores (maximum score = 5, minimum score = 1) of the day's first case were compared. RESULTS: About 536 slides (surgeon 1 = 277, surgeon 2 = 259) were evaluated from 2,825 cases. Mean quality assessment scores were similar between surgeons (4.89 and 4.86; P = 0.31) with missing or folded epidermis being the most commonly reported issue for both surgeons. CONCLUSION: Similar slide quality can be achieved via both beveled and non-beveled Mohs cutting angles. While more relaxing incisions may be necessary to optimize tissue flattening with non-beveled incisions, there is no associated increased loss of epidermal margins. The potential benefits of non-beveled incisions, such as minimizing tangentially cut adnexal structures and creating vertical wound edges optimized for repair, may offer an alternative technique with positive clinical implications.

BACKGROUND: Cutaneous squamous cell carcinoma (cSCC) is the second most common cancer in the United States. Cutaneous squamous cell carcinoma has an estimated incidence of more than 700,000 new cases per year and a 5% risk of metastasis. OBJECTIVE: To provide clinicians with guidelines for the management of cSCC based on evidence from a comprehensive literature review and consensus among the authors. MATERIALS AND METHODS: The authors conducted an extensive review of the medical literature on treatment methods for cSCC, taking into consideration cure rates, recurrence and metastatic rates, aesthetic and functional outcomes, and cost effectiveness of the procedures. RESULTS: Surgical treatments provide the best outcomes for cSCC. Mohs micrographic surgery is a cost-effective procedure that affords the highest cure rate, maximal tissue preservation, and superior cosmetic outcomes. Nonsurgical methods may be used as a primary treatment for low-risk squamous cell carcinomas, but the cure rates are lower. CONCLUSION: The cure rate remains the most important consideration in choosing the treatment method, but additional factors, such as the patient's general medical condition, psychosocial circumstances, the location of the tumor and cost effectiveness of the therapy should be considered. Mohs micrographic surgery remains the preferred treatment for high-risk tumors and tumors located in cosmetically sensitive areas.

IMPORTANCE: Excisional skin cancer surgery is a common procedure, with no formal consensus for mitigating the risk of wrong-site cutaneous surgery. OBJECTIVE: To systematically consider the usefulness and feasibility of proposed methods for correct biopsy site identification in dermatology. EVIDENCE REVIEW: Survey study with a formal consensus process. Item development was via a literature review and expert interviews, followed by 2 stages of a Delphi process to develop consensus recommendations. FINDINGS: In total, 2323 articles were reviewed in the literature search, with data extraction from 14. Twenty-five experts underwent 30-minute structured interviews, which were transcribed and coded. The resulting survey was composed of 42 proposed interventions by multiple stakeholders (biopsying physicians, operating physicians, nurses, ancillary staff, patients, caregivers, and family members) at 3 time points (day of biopsy, delay and consultation period, and day of definitive surgery). Two rounds of a Delphi process with 59 experts (25 academic and 34 private practice) scored the survey. Strong consensus was obtained on 14 behaviors, and moderate consensus was obtained on 21 other behaviors. In addition, a 2-state simultaneous algorithm was developed to model surgeon behavior on the day of definitive surgery based on surgeon and patient perceptions. CONCLUSIONS AND RELEVANCE: When definitive surgery is performed after the initial biopsy and by a different surgeon, procedures can be implemented at several time points to increase the likelihood of correct site identification. The specific circumstances of a case suggest which methods may be most appropriate and feasible, and some may be implemented. The risk of wrong-site cutaneous surgery can be reduced but not eliminated.

Cutaneous SCC is the second most common skin cancer among whites. Most cases of primary cutaneous SCC are induced by UV radiation. Chronic sun exposure is the major risk factor, and favored locations include the head and neck and other sun-exposed areas. Moreover, it is important for the clinician to recognize other risk factors associated with this malignancy, including HPV infection, occupational exposures, various genodermatoses, scarring dermatoses, chronic wounds, and burn scars. The allogenic transplant population is at most risk for developing cutaneous SCC. For these patients, aggressive patient education, control of immunosuppression, and clinical surveillance should be the standard of care. Most patients who have primary SCC have an excellent prognosis, and treatment is usually straightforward. A substantial minority of these neoplasms, however, may recur or metastasize. Obtaining a complete history and performing a total-body skin examination can help to identify tumors at high risk for recurrence or metastasis in addition to those that may be more easily treated. For those individuals with metastatic disease, however, the long-term prognosis is guarded. Based on recent reports, in the future, there may be a role in SLNB for cutaneous SCC to diagnose subclinical metastasis accurately. Larger studies and better guidelines need to be developed before SLNB can be routinely used in the management of metastatic disease. Physicians should emphasize to their patients the benefits of sun avoidance and protection from sunlight, beginning in childhood, to minimize the risk for developing this potentially life-threatening neoplasm.

OBJECTIVE: To review our experience with lentigo maligna, a melanoma in situ that occurs primarily on the head and neck in older adults, and reconstructive efforts applied in managing the large defects following lentigo maligna excision that are not amenable to primary closure. METHODS: We reviewed the records of 23 patients who underwent serial excision of lentigo maligna using a modified Mohs technique. We compared the sizes of the initial lesion and postexcision defect, examined photographs taken before and after surgery, and studied techniques used in reconstruction. RESULTS: The final surgical defect after staged Mohs excision of lentigo maligna lesions ranged from 2 to 10 times the original lesion size. Invasive melanoma was identified in 2 surgical specimens on pathologic evaluation. We reviewed successful reconstructive techniques including local flaps and tissue expansion. CONCLUSIONS: Surgical excision remains the standard of care for lentigo maligna. Because of the subclinical spread and extensive radial growth characteristic of these lesions, patients are often left with large defects that are not amenable to primary closure. Appropriate preoperative patient counseling includes preparation for the possibility of a large surgical defect that requires staged reconstruction. Creative techniques, including local flaps and tissue expansion, must be in the head and neck reconstructive surgeon's armamentarium for the management of defects following lentigo maligna excision.

BACKGROUND: Microcystic adnexal carcinoma (MAC) is a rare and aggressive malignant tumor of the sweat glands. Clinically, it often presents as a firm subcutaneous nodule on the head and neck regions. On histology, MAC exhibits both pilar and sweat duct differentiation with a stroma of dense collagen. It often extends beyond the clinical margins with local spreading in the dermal, subcutaneous, and perineural tissue planes. It has a high local recurrence rate after standard excision. Recent preliminary reports have indicated more favorable cure rates with Mohs' micrographic surgery (MMS). OBJECTIVE: To present our data on four cases of MAC treated by MMS. We also compared our findings with more recently reported series in the English language literature. METHODS: We reviewed the medical records of four patients (two males and two females) with MAC treated by MMS over the last 3 years. We also obtained follow-up data. RESULTS: In all four patients with MAC treated by MMS, there were no recurrences, with a mean follow-up of 1 year. CONCLUSION: We report an additional four MAC cases treated by MMS. The accumulated data continue to confirm that, if the diagnosis of MAC is made early, and if the anatomic location is accessible to excision by MMS, a favorable outcome can be expected.

BACKGROUND: Endocrine mucin-producing sweat gland carcinoma is a very rare cutaneous tumor that has been reported only in three patients previously. We report a case of an endocrine mucin-producing sweat gland carcinoma associated with mucinous carcinoma treated by Mohs' micrographic surgery. OBJECTIVE: The purpose of this report is to test the utility of Mohs' micrographic surgery in the treatment of mucinous carcinomata. METHODS: A 79-year-old female with a 2-year history of four lesions of biopsy-proven endocrine mucin-producing sweat gland carcinomas and mucinous carcinoma was treated with Mohs' micrographic surgery. RESULTS: Three of the lesions were completely cleared by Mohs' micrographic surgery. The fourth lesion, in the right lateral canthus, was not cleared by the Mohs' technique because of its location within the orbit and the difficulty of retraction of the globe for appropriate visualization and excision. The patient underwent wide excision of the remaining orbital tumor and reconstruction, which was successfully accomplished. The patient did not experience a recurrence in any of her four lesions over a 2-year follow-up period. CONCLUSION: Mohs' micrographic surgery is an appropriate treatment for mucinous carcinomata, including endocrine mucin-producing sweat gland carcinoma and mucinous carcinoma.
