Basal Cell Carcinoma Formation Within A Spinal Cord Stimulator Surgical Scar: A Case Report.

Implanting neuromodulation devices requires that pain medicine physicians be well-versed in proper surgical technique and postoperative wound management. To be able to identify abnormal wound healing, a basic understanding of normal wound healing is required. When postoperative wounds deviate from expected healing, it is important that pain medicine physicians entertain a broad differential diagnosis, including nonsurgical dermatologic pathology.

Results of Mohs' Micrographic Surgery of Periocular Basal Cell Carcinoma: The Swedish Experience.

The Department of Ophthalmology, Sahlgrenska University Hospital, has until recently been the only eye clinic in the Nordic countries to perform Mohs' micrographic surgery of basal cell carcinoma. This has led to the practice of only the most complicated basal cell carcinomas being operated on with this technique. The purpose of this study was to present the results of these surgeries in patients with at least 5 years of follow-up. A retrospective study of all patients operated upon in 2010-2015 was performed. Data were gathered from their medical charts. Primary outcome was recurrence of basal cell carcinoma. One-hundred and sixty-seven patients were operated on. Mohs' micrographic surgery was used for tumours that were judged as highly aggressive on preoperative biopsy, had ill-defined borders, had recurred after previous surgery, or a combination of these factors. Nine recurrences (5.4% of all radical Mohs' micrographic surgeries) were diagnosed after a mean postoperative time of 37 months (4-84 months). Interestingly, all of these 9 recurrences after Mohs' micrographic surgery were in patients who had such surgery because of a recurrent basal cell carcinoma to start with. Good results can be achieved when operating on the most complicated periocular basal cell carcinomas with Mohs' micrographic surgery but special care has to be taken to ensure radical borders when operating on recurring basal cell carcinomas.

Excision pathways for keratinocyte cancers diagnosed by teledermatology: a retrospective review.

Introduction The New Zealand population has one of the highest incidences of skin cancer in the world. Hospital waiting lists for surgical excision of keratinocytic skin cancers (basal cell carcinoma and squamous cell carcinoma) are lengthy, and increasingly, excisions are undertaken in primary care. Teledermatology, in response to general practitioners' electronic referrals (e-referrals), can improve clinical communication between general practitioners and dermatologists. Aim The aim of this study was to evaluate an excision pathway for keratinocytic cancers diagnosed by teledermatology. Methods A retrospective observational descriptive review of a 3-month cohort of primary care e-referrals was undertaken. Results Three hundred and fifty eight suspected keratinocytic cancers (KCs) were diagnosed by teledermatology; histology reports confirmed KC in 201 of 267 excisions (75%). The majority (77.2%) were excised by general practitioners an average of 25 days after the dermatologist's recommendation. The rest were excised by plastic surgeons in private (3.4%) or at a public hospital (19.5%) after an average of 40 or 134 days, respectively. Discussion E-referral pathways are now widely implemented. However, the ideal workflow for skin cancer management is unknown. We have demonstrated in New Zealand that surgery can be undertaken in primary care within a month of a teledermatology diagnosis and excision recommendation. Conclusion This study reports prompt excision of KCs by general practitioners after an e-referral and a teledermatology response.

Primary basal cell carcinoma of the caruncle: case report and review of the literature.

We present a rare case of primary caruncle basal cell carcinoma (BCC), a condition with limited occurrences. Our patient, an 80-year-old woman without prior ocular pathological history, presented a 2x2mm pedunculated blackish nodular lesion on the caruncle of her left eye, without local conjunctival or cutaneous involvement. Histological analysis following complete excision confirmed the presence of basal cell carcinoma within the caruncle. Over a span of 30 months, no recurrence has been observed. While scant cases are documented in the literature, we conducted a review of these instances. Despite its infrequent manifestation, this condition should be taken into account when evaluating caruncular tumors, given its tendency to invade the orbit. Complete excision with free surgical margins is the treatment of choice, and adjuvant radiotherapy or chemotherapy might be considered.

Basal Cell Carcinoma With Metastasis to the Thoracic Spine: An Uncommon Case Report and Review of the Literature.

Basal cell carcinoma is an exceedingly rare cause of spinal metastatic disease for which the treatment algorithm is poorly defined. We present a positive patient outcome after treatment of T8 metastatic basal with posterior decompression and fusion followed by later anterior reconstruction, in addition to targeted radiation therapy and pharmacologic therapy. In general, a personalized and comprehensive treatment approach should be used, incorporating surgical, oncologic, and pharmacologic methods as able. Moreover, primary preventive medical and mental health care can help prevent delayed presentation and increased access to timely care.

Line-field confocal optical coherence tomography of eyelid margin growths: A case series.

BACKGROUND: The clinical differential diagnosis of lesions arising on the eyelid margin may be challenging and an unneeded surgical approach may have serious functional and aesthetic consequences. Nonetheless, early recognition and treatment of malignant tumors of the eyelid margin is mandatory. Line-field confocal optical coherence tomography (LC-OCT) is a novel tool for the in vivo, real-time skin imaging. OBJECTIVES: The aim of the study was to identify and analyze the LC-OCT features of a series of eyelid margin growths and to correlate these features with the histopathological findings. METHODS: Patients with eyelid margin growths who were scheduled for lesion excision underwent LC-OCT examination. Inclusion criteria were a challenging clinical aspect of the lesions and a clinical history of recent onset (up to 12 months). In all cases, the histopathological examination of the excised lesions was performed for the final diagnosis. RESULTS: A total of 31 lesions located on the upper (13 cases) or lower (18 cases) eyelid margin from 28 consecutive patients (male = 15, female = 13; mean age: 64.7 years, range: 44-87 years) were evaluated and excised. The histopathologic diagnoses were nodular basal cell carcinoma (BCC) (nine cases), squamous cell carcinoma (SCC) (three cases), compound nevus (four cases), dermal nevus (two cases), seborrheic keratosis (four cases), pyogenic granuloma (one case), trichilemmal cyst (three cases), and hidrocystoma (five cases). LC-OCT allowed the in vivo recognition of the main microscopic features of the examined lesions. CONCLUSIONS: LC-OCT represents a promising tool for the evaluation of eyelid margin lesions. Advantages of non-invasive diagnosis particularly relevant in such a sensitive region include a more correct planning of the treatment and, in case of surgery, the most appropriate surgical approach and, importantly, a correct timing of intervention.

Can the Safe Surgical Margin Be Narrowed in Early-Stage Facial Basal Cell Carcinoma?

OBJECTIVE: To examine factors that affect the positive surgical margins of facial basal cell carcinoma (BCC) and investigate whether the surgical margin value can be narrowed in early-stage facial BCCs. METHODS: Ninety-five patients were divided into the three groups based on prognosis: good (n = 48), mixed (n = 32), and poor (n = 15). The good prognosis group (group 1) included nodular and superficial subtypes; the mixed prognosis group (group 2) included nodular-infiltrative, nodular-micronodular, and nodular-sclerosing subtypes; and the poor prognosis group (group 3) included infiltrative and micronodular subtypes. RESULTS: Groups 1 and 2 differed from each other significantly in terms of positive surgical margin (P = .002) and tumor thickness (P = .008), but group 3 did not (P = .851 and P = .804, respectively). With regard to surgical method (primary vs local flap repair), only tumor localization varied significantly (P < .001). CONCLUSIONS: Groups differed significantly in terms of surgical margin positivity, the distance of the tumor to the surgical margin, and the tumor thickness. The intact surgical margin was 2 mm on average in this study, and the authors suggest that it may be possible to revise the surgical margin values recommended in the literature.

Trapdoor Deformity Correction Post Nasal Bilobed Flaps for Basal Cell Carcinoma Reconstruction With Multiple Laser Modalities.

ABSTRACT: In case of excision of nasal basal cell carcinoma (BCC), bilobed flaps are considered the criterion standard of reconstruction for defect less than 15 mm in size. However, there is still a risk of trapdoor deformity formation, of which its treatment is less discussed. A 44-year-old woman who was diagnosed with nasal BCC and underwent tumor excision with bilobed flap reconstruction presented with trapdoor deformity postoperatively. The computed Vancouver Scar Scale was 7. After early intervention of multiple laser modalities, including 2 sessions of 585-nm pulsed dye laser with a fluence of 9 J/cm2, pulse duration of 6 milliseconds, and spot size of 6 mm, 2940-nm Er-yttrium aluminum garnet (YAG) laser with a pulse energy of 800-900 mJ, repetition rate of 8-9 Hz, and laser spot size of 3-7 mm, and 5 sessions of 1064-nm Nd:YAG fractional picosecond laser with a pulse energy of 2.30-2.70 mJ, repetition rate of 8 Hz, and laser spot size of 6 mm from 5 to 23 weeks postoperatively, the Vancouver Scar Scale score improved to 1, with significant reduction of trapdoor scar erythema and puffiness. Although BCC is often curable, tumor excision causes unsatisfactory appearance satisfaction problem, owing to the apparent location of the lesion. Factors, such as sebaceous tissue thickness, reconstruction over multiple aesthetic subunits of nose, and damage to nasal cartilage framework structure during tumor removal, may increase the risk of trapdoor formation. Early intervention with multiple laser treatment can significantly revise the deformity.

Head and neck nonmelanoma skin cancers: surgical management and debated issues.

PURPOSE OF REVIEW: This review critically assesses the current literature and guidelines, aiming to clarify some of the most important factors that impact surgical strategies of head and neck nonmelanoma skin cancers (NMSCs), focusing on squamous, basal, and Merkel cell carcinomas. RECENT FINDINGS: Recent developments underscore the complexity of treatment for NMSC, particularly in the head and neck region. There is a lack of high-level evidence for the management of these tumors, especially in advanced stages. The need to tailor the extent of surgical margins and parotid/neck management to different histotypes, considering the varying risk factors for recurrence, is beginning to emerge in the literature. Moreover, the role of immunotherapy and targeted therapies for locally advanced disease, alongside traditional treatment options, is progressively growing. SUMMARY: NMSCs represent a heterogeneous group of malignancies with varying treatment complexities and prognoses. Management of NMSC is evolving towards an increasingly personalized strategy within a multidisciplinary therapeutic framework.

Removal of Incidental Skin Cancer During Mohs Micrographic Surgery Indicated for a Different Primary Tumor.

BACKGROUND: Mohs surgery is a tissue-sparing, microscopically controlled procedure used to treat biopsy-proven skin cancers. Because Mohs surgery allows for examination of the complete margin of each tissue layer removed, separate cancers can be treated concomitantly when identified. As early detection of skin cancer is beneficial for reducing morbidity, incidental tumors discovered during Mohs surgery are of significant interest. OBJECTIVE: Our objective was to determine the prevalence and characteristics of incidental skin cancers found during Mohs surgery. METHODS: A retrospective chart review of cases seen at University of California, San Diego, from 2014 to 2021 was performed. RESULTS: Of 13,464 Mohs surgery cases, 4.53% ( n = 610) had incidental skin cancers found during removal of the initially identified tumor. Of the 610 cases, 88.4% ( n = 539) had basal cell carcinoma as the primary tumor and either squamous cell carcinoma (SCC) or SCC in situ as the incidental tumor. About 7.87% ( n = 48) had SCC as the primary tumor and basal cell carcinoma as the incidental tumor. All tumors were removed with clear margins and without significant complications. CONCLUSION: Diagnosis of incidental tumors during Mohs surgery enables early detection of skin cancer and circumvents the need for additional surgery, likely resulting in decreased morbidity and improved cost-effectiveness.
