Lentigo maligna is a lentiginous proliferation of atypical melanocytes confined to the epidermis, typically on chronically sun-damaged skin. Following biopsy and exclusion of invasive disease, therapy may involve Mohs surgery, topical treatment or radiotherapy. However, lentigo maligna often involves adnexal structures, creating histological difficulty in distinguishing these foci from invasive...

BCC: basal cell carcinoma MMS: Mohs micrographic surgery NAC: nipple-areolar complex INTRODUCTION Basal cell carcinoma (BCC) is the most common type of skin cancer and is seen rarely on the nippleareolar complex (NAC) in men and women. We present a case of a 47-year-old woman referred for Mohs micrographic surgery (MMS) for BCC on the nipple. Close examination of frozen section specimens during...

We report a 58-year-old woman with cutaneous adenoid cystic carcinoma arising on the chest treated with Mohs micrographic surgery. The patient remained tumor-free at 24-month follow-up. To date, only six other cases of cutaneous adenoid cystic carcinoma were reportedly managed by Mohs surgery. Cutaneous adenoid cystic carcinoma has low potential for distant metastasis but is notorious for its a...

BACKGROUND Surgical reconstructive planning following Mohs surgery can be a difficult subject for dermatology residents to master. Prior research demonstrates that active learning is preferred and more effective compared to passive learning models and that dermatology residents desire greater complexity and volume in surgical training. We present a novel, active, problem-based learning tool for...

OBJECTIVES To estimate and compare the recurrence rates of basal cell carcinoma (BCC) after Mohs surgery in patients with chronic lymphocytic leukemia (CLL) and controls and to evaluate differences among histologic subtypes of BCC. DESIGN Retrospective assessment of clinical histories, postoperative notes, and surgical photographs. SETTING Tertiary-care institution (Mayo Clinic, Rochester, ...

OBJECTIVES To compare a rapid, cross-sectional frozen-section technique with Mohs micrographic surgery, using recurrence rate and cost of treatment for excision of basal cell carcinoma as indicators to validate our indications for Mohs surgery. DESIGN Retrospective study of 557 head and neck basal cell carcinomas excised over 10 years. MAIN OUTCOME MEASURES Recurrence rates; tumor compariso...

BACKGROUND Microcystic adnexal carcinoma (MAC) is a malignant appendageal tumor first described in 1982. It can be clinically and histologically confused with other malignant and benign cutaneous neoplasms, leading to inadequate initial treatment. This neoplasm is locally aggressive and deeply infiltrating, characterized by high morbidity and frequent recurrence. Mohs micrographic surgery has b...

Pigmented basal cell carcinoma (PBCC) occurs more frequently in Asian population. The efficacy of fluorescence diagnosis (FD) for PBCCs treated with Mohs micrographic surgery has not yet been determined. This study enrolled 255 patients with 258 biopsy-proven BCC lesions: 199 PBCCs (77.1%) and 59 non-PBCCs (22.9%). We compared the clinicopathological and surgical features of the PBCCs and non-P...
