Review
The association of bullous pemphigoid with melanoma remains controversial and poorly understood. Recent studies report the presence of the bullous pemphigoid antigen, BP180, in melanoma cells, yet not normal melanocytes, suggesting an underlying mechanism for cases of melanoma-associated bullous pemphigoid. We report on an 88-year-old woman who showed a temporal relationship between the development of bullous pemphigoid and melanoma. The patient did not receive programmed death ligand 1 inhibitor therapy and improved rapidly following complete excision of her melanoma, with clobetasol, doxycycline, and niacinamide. We review the literature on the relationship between bullous pemphigoid and melanoma, and propose a mechanism underlying a melanoma-associated bullous pemphigoid.

Review
BACKGROUND
Lymphatic mapping and sentinel lymph node biopsy is an established technique for the staging and treatment of melanoma. The success of lymphatic mapping in this realm has broadened its application to other solid neoplasms. This update reviews the status of sentinel lymph node biopsy in its most widely cited applications.
METHODS
Seminal manuscripts on lymphatic mapping in melanoma, breast, colon, vulvar, cervical, lung, gastric, and head and neck cancers are reviewed.
RESULTS
Studies suggest that the application of lymphatic mapping as a staging tool in breast cancer and melanoma is justified when applied by trained surgeons. Additional validation is necessary before sentinel node biopsy is advocated in gynecologic, colon, lung, and head and neck cancer.
CONCLUSIONS
As in breast cancer and melanoma, validation of the sentinel node concept in other solid tumors must occur in institutions other than those in which the technique is being developed before it is generally applied to other neoplasms.

Mucosal melanomas (MM) are a rare type of melanomas commonly found in the vulvovaginal, anorectal, and respiratory tract. In this case report, a 71-year-old female presented to her OB/GYN clinic with dark raised mass on her right labial region adjacent to the perineum. Past medical and surgical history of note included third-degree uterine prolapse, senile vaginitis, fibrocystic changes of the breasts bilaterally, hypothyroidism, hypertension, as well as a past hysterectomy and anterior colporrhaphy. Upon further workup, the 2.7 x 1.8 x 2 cm polyploid mass was biopsied and was found to be consistent with malignant melanoma. The patient then underwent a wide local excision confirming that the lesion was a nodular vulvar melanoma with superficial ulcerations and lymphovascular invasion of the vulvar region. Post-wide local incisions were found to be healed well after the procedure and the patient was referred to a gynecological oncologist for continuous monitoring. The purpose of this case report is to bring awareness of melanomas arising in atypical regions. While MMs are rare in comparison to cutaneous melanomas (CM), the prognosis can be poor if not caught early.

BACKGROUND
Immediate lymphatic reconstruction (ILR) has traditionally required a fluorescent-capable microscope to identify lymphatic channels used to create a lymphaticovenous bypass (LVB). Herein, a new alternative method is described, identifying lymphatic channels using a commercially available handheld fluorescence imaging device.
METHODS
This was a single-center study of consecutive patients who underwent ILR over a 1-year period at a tertiary medical center. Intradermal injection of fluorescent indocyanine green dye was performed intraoperatively after axillary or inguinal lymphadenectomy. A handheld fluorescent imaging device (SPY-PHI, Stryker) rather than a fluorescent-capable microscope was used to identify transected lymphatic channels. Data regarding preoperative, intraoperative, and outcome variables were collected and analyzed.
RESULTS
The handheld fluorescent imaging device was successfully able to identify transected lymphatic channels in all cases (n = 15). A nonfluorescent-capable microscope was used to construct the LVB in 14 cases. Loupes were used in one case. In 13 cases, ILR was unilateral. In two cases, bilateral ILR was performed in the lower extremities. All upper extremity cases were secondary to breast cancer (n = 7). Lower extremity cases (n = 8) included extramammary Paget disease of the penis, ovarian cancer, vulvar squamous cell carcinoma, squamous cell carcinoma of unknown origin, soft tissue sarcomas, cutaneous melanoma, and porocarcinoma.
CONCLUSIONS
ILR, using indocyanine green injection with a handheld fluorescent imaging device, is both safe and effective. This method for intraoperative identification of lymphatic channels was successful, and LVB creation was completed in all cases. This approach makes ILR feasible when a fluorescent-capable microscope is unavailable, broadening access to more patients.

Basal cell carcinoma (BCC) is a major non-melanoma skin cancer, and its incidence is increasing worldwide. Although the main etiology is sun exposure, BCC may develop in sun-protected areas such as the vulva. The sonic hedgehog signaling pathway mutation may explain the mechanism underlying the occurrence of vulvar BCC. Owing to the rarity of metastases, wide local excision is an appropriate treatment option. Here, we report the cases two postmenopausal women with vulvar BCC who were surgically treated.

BACKGROUND
Recognizing Langerhans cell histiocytosis (LCH) might be a challenge due to its rarity. Reflectance confocal microscopy (RCM) and dermoscopy were emergent promising non-invasive technique as auxiliary tools in diagnosis of different skin conditions. However, the RCM and dermoscopic features of LCH had been less investigated. To reveal the common RCM and dermoscopic features of LCH.
MATERIALS AND METHODS
Forty cases of LCH were retrospectively analyzed according to age, locations, clinical, RCM, and dermoscopic features from September 2016 to December 2022. To reveal the differences and common in clinical, RCM, and dermoscopic features that occur in different anatomic location.
RESULTS
In the study, sites of predilection include the trunk 31/40 (77.5%), extremity 21/40 (52.5%), face 14/40 (35%), scalp 11/40 (27.5%), vulvar 4/40 (10%), and nail 2/40 (5%). All LCHs had the common RCM features. There were significant differences in clinical and dermoscopic features for age and lesion anatomic site. The common dermoscopic features for scalp, face, trunk, and extremity were the erythematous scaly rash, purplish-red globules or patches, scar-like streaks with ectatic vessels. While the features for nail LCH were purpuric striae, onycholysis and purulent scaly rash, and the erosive erythematous plaque and purulent scaly rash for vulvar LCH. The common RCM features of all LCH showed a focal highly reflective dense image in the surface keratin layer, epidermis architectural disarray, obscuration of dermo-epidermal junction, numerous polygonal, large, medium reflective, short dendrites cells in the epidermis, and dermis. All LCH involving the vulvar and nail did not manifest skin lesions.
CONCLUSION
RCM and dermoscopy showed promising value for diagnosis and differentiation of LCH.

BACKGROUND
The objective of this study was to evaluate the author's recent, preliminary experience with the sentinel lymph node procedure in patients with vulvar melanoma and to compare this experience with treatment and follow-up of patients with vulvar melanomas who were treated previously at their institution.
METHODS
From 1997, sentinel lymph node procedure with the combined technique (99mTechnetium-labeled nanocolloid and Patente Blue-V) was performed as a standard staging procedure for patients with vulvar melanoma with a thickness > 1 mm and no clinically suspicious inguinofemoral lymph nodes. For the current study, clinicopathologic data from all 33 patients with vulvar melanoma who were treated between 1978 and 2000 at the University Hospital Groningen were reviewed and analyzed.
RESULTS
From January 1997 until December 2000, identification of sentinel lymph nodes was successful in all nine patients who were referred for treatment of vulvar melanoma. Three patients underwent subsequent complete inguinofemoral lymphadenectomy because of metastatic sentinel lymph nodes. In follow-up, groin recurrences (in-transit metastases) occurred in two of nine patients, both 12 months after primary treatment. Both patients had melanomas with a thickness > 4 mm and previously had negative sentinel lymph nodes. There was a trend toward more frequent groin recurrences in patients after undergoing the sentinel lymph node procedure (2 of 9 patients) compared with 24 historic control patients (0 of 24 patients; P = 0.06). Five of 33 patients developed local recurrences: Two patients had groin recurrences, and 11 patients developed distant metastases. Twelve patients died of vulvar melanoma. Seventeen patients with a median follow-up of 66 months (range, 9-123 months) are currently alive (overall survival rate, 52%).
CONCLUSIONS
Although the numbers were small, this study showed that the sentinel lymph node procedure is capable of identifying patients who have occult lymph node metastases and who may benefit from lymphadenectomy for locoregional control and prevention of distant metastases. However, the data also suggest that the sentinel lymph node procedure may increase the risk of locoregional recurrences (in-transit metastases), especially in patients with thick melanomas. The potential role of the sentinel lymph node procedure as an alternative method of lymph node staging in patients with vulvar melanoma needs further investigation only within the protection of clinical trials and probably should be restricted to patients with melanomas with intermediate thickness (1-4 mm).
