BACKGROUND: Dermatofibrosarcoma protuberans (DFSP) typically affects the dermis and subcutaneous tissue. The subcutaneous variant is rare. OBJECTIVE: We sought to characterize the subcutaneous DFSP (SC-DFSP) variant and compare it with cutaneous DFSP (C-DFSP). METHODS: This work was a retrospective study of DFSP treated in our institution. RESULTS: Of 124 cases of DFSP, 18 were SC-DFSP (14.5%). Except for the deep location, the pathologic and genetic features were indistinguishable from the C-DFSP variant...

Poor cosmetic outcome is associated with significant negative impact on quality of life (QOL).(1) The degree of psychosocial distress may be more correlated with patient perception rather than objective scar severity. The patient's personal assessment is the primary influence on psychosocial morbidity.(1) Therefore, patient-reported outcome (PRO) instruments are valuable in assessing cosmetic outcome and impact on QOL.

Micrographic surgery is currently the only technique which ensures complete removal of basal cell carcinomas. The major limitation is the high set-up cost, which is particularly connected with specialized training of surgeons, technicians and the set-up of a histology facility for frozen tissue sectioning and staining. In the long run, however, the cost of Mohs surgery per patient does not exceed that of conventional surgery. The technique is very safe and has multiple advantages over any other treatment modality...

A 68-year-old gentleman presented with a lesion that resembled a pyogenic granuloma in his inferior fornix. The lesion was excised and biopsy demonstrated a proliferation of malignant spindle cells. Three weeks following initial excision, the lesion recurred and was removed via wedge excision of the eyelid. Definitive clearance was achieved through Mohs micrographic surgery. The patient received adjuvant postoperative radiotherapy and remains disease-free. This case demonstrates the need to consider sinister pathology in the setting of recurrent periocular lesions...

Importance: The best surgical treatment modalities for subungual squamous cell carcinoma (SUSCC) without bone invasion need to be determined. The limited available data on Mohs micrographic surgery do not demonstrate its use as a standard procedure. A previous study in a limited series of patients has shown that wide surgical excision of the nail unit was associated with a low rate of recurrence. Objectives: To confirm the efficiency of wide surgical excision of the nail unit with full-thickness skin graft reconstruction on a series of patients with SUSCC with an extended follow-up and to evaluate short- and long-term postoperative morbidity and patient satisfaction...

BACKGROUND: The use of Mohs micrographic surgery (MMS) has increased greatly to treat basal cell and cutaneous squamous cell carcinomas (keratinocyte carcinoma [KC]), and consensus-based Appropriate Use Criteria (AUC) were developed to identify tumors for which MMS is appropriate. OBJECTIVE: We sought to compare recurrence rates after different treatments in tumors judged appropriate for MMS. METHODS: We used data from an observational prospective cohort study and retrospectively categorized consecutive tumors as appropriate for MMS according to the AUC...

BACKGROUND: Effective Mohs surgery depends on accurate histopathological identification and mapping of tumor burden to ensure complete removal of tumor. OBJECTIVE: The purpose of this study is to evaluate whether using a photograph of the histopathological slide as the Mohs map improves mapping accuracy. METHODS AND MATERIALS: Single-blinded pilot study. Five dermatology residents at one academic institution mapped 11 cases of basal cell carcinoma using both traditional hand-drawn maps and color photographic maps...

INTRODUCTION: Malignant cutaneous adnexal neoplasms are rare and have been characterized only recently. They can occur at any age but preferentially in elderly. There are 3 of them: trichoblastic carcinoma, trichilemmal carcinoma and malignant pilomatricoma. The aim of our study was to make a diagnostic and therapeutic update about these tumors when located at the face or at the scalp. MATERIALS AND METHODS: A bibliographic research was made on PubMed using following keywords: appendage skin carcinoma AND pathology AND/OR therapeutic...

Importance: Nasal reconstruction after Mohs surgery is a unique challenge in that it must satisfy both functional and aesthetic goals. Despite some advocacy in the literature for using structural reinforcement to achieve both functional and aesthetic outcomes in soft-tissue reconstruction, no study has validated this claim by comparing reconstruction with and without structural support. Objective: To evaluate the effectiveness of and need for structural reinforcement when reconstructing the nasal alar and sidewall subunits...

BackgroundPoorly controlled hypertension is a known risk factor for surgical complications. OBJECTIVE: This study examines the incidence of complications in participants undergoing Mohsmicrographic surgery (MMS) based on preoperative blood pressure (BP) measurement and investigates the role of potential confounders in the relationship between preoperative BP and postoperative complications.MethodsThis 10-month prospective cohort study at the University of California, San Francisco (UCSF) Dermatologic Surgery Center approached all patients undergoing MMS for participation and assessed for the diagnosis of hypertension, anti-hypertensive medication use, use of tobacco or blood thinners, immunosuppression, concomitant diabetes, or previous treatment with radiation therapy at the surgical site...

Cutaneous squamous cell carcinoma (cuSCC) comprises 15-20% of all skin cancers, accounting for over 700,000 cases in the U.S. annually. Most cuSCC arise in association with a distinct precancerous lesion, the actinic keratosis (AK). In order to identify potential targets for molecularly targeted chemoprevention, we performed integrated cross-species genomic analysis of cuSCC development through the preneoplastic AK stage using matched human samples and a solar UV- driven Hairless mouse model. We performed RNA-seq and microRNA-seq on samples from both patients undergoing Mohs surgery and the mouse model...

Leigh Sutton, Palak Parekh
Gout is the most common cause of inflammatory arthritis in men over 40 [1]. The prevalence of gout in the US is approximately 3.9%. Tophus is a characteristic sign of gout and results when monosodium urate deposits at the joint, skin, or cartilage. Tophi develop in 12-35% of patients who are diagnosed with gout [2]. We report a case of a 70-year-old man who was diagnosed with squamous cell carcinoma of the helix via shave biopsy. During Mohs micrographic surgery, a vigorous foreign-body reaction was noted. Review of the initial biopsy slides identified crystals with pseudoepitheliomatous hyperplasia (PEH) rendering a diagnosis of gout...

We report several scenarios of compromise in patient safety owing to the re-use of mis-assigned patient's surgical instruments in Mohs micrographic surgery.We discuss the breaks in universal protocols that others may experience in their practices and describe corrective measures that our institutions employed to avoid such future events.There is a lack of publication in the literature on the topic of mis-assigned instrument use in Mohs surgery. We believe that the  practice of re-using instruments is cost-effective and therefore common...

A 41-year-old man from Cuero, Texas with a nonhealinglesion on his left cheek was referred to ourclinic for removal of a squamous cell carcinoma. Thepatient first noticed a "pimple" on his left cheek 3-4months prior to presentation. When the lesion beganto grow he presented to his primary care physician anda biopsy was taken, showing "atypical squamous cellproliferation." Mohs surgery was performed and thenodule was removed with no evidence of malignancyseen on histopathology. Upon review of the surgicalbiopsies by consulting pathologists, the diagnosis ofleishmaniasis was established and later confirmed bythe Center for Disease Control and Prevention (CDC)as Leishmania mexicana...

BACKGROUND: Mohs surgery is indisputably a highly effective treatment for nonmelanoma skin cancers. In the current health care environment, physicians are challenged to provide high quality, efficacious care in a manner that is mindful of the patient's general health and well-being. We have used a functional assessment to evaluate older patients who present for Mohs surgery. OBJECTIVE: The purpose of this study is to categorize the functional status, using the Karnofsky Performance Status (KPS) Scale, of patients 75 years and older undergoing Mohs surgery of a nonmelanoma skin cancer and to identify distinguishing characteristics of lower functioning patients...
