RESUMEN

BACKGROUND: The prognosis and treatment of basal cell carcinoma (BCC) are largely dependent on tumor subtype, which is typically determined by punch or shave biopsy. Data regarding concordance between BCC subtype on initial biopsy and final histopathology for Mohs micrographic surgery (MMS) or excision with frozen sections (EFS) are limited. OBJECTIVES: To determine the concordance between initial biopsy and final MMS or EFS subtyping of BCC. We aim to investigate the incidence and clinical characteristics of lesions initially diagnosed as superficial BCC (sBCC) that are later found to have a nodular, micronodular, or infiltrative component. METHODS: We conducted a retrospective review of all MMS or EFS cases performed at a single academic center from August 1, 2015, to August 31, 2017. Inclusion criteria were a biopsy-proven diagnosis of sBCC and presence of residual tumor following stage I of MMS or EFS. Fisher’s exact test was used to evaluate significance of clinical characteristics and outcomes associated with the presence of a nodular, micronodular, or infiltrative BCC component. RESULTS: A total of 164 MMS or EFS cases had an initial biopsy showing sBCC. Of these, 117 had residual BCC on stage I, and 43 (37%) were found to have a nodular, micronodular, or infiltrative component. Significant predictors of reclassified BCC subtype included age over 60 years (P= 0.006) and location on the head or neck (P=0.043). Reclassified lesions required significantly more stages of MMS to clear (P=0.036). Shave biopsy was used to diagnose 114 (97%) of the included cases. CONCLUSIONS: Over one third of shave biopsies that initially diagnosed sBCC failed to detect a nodular, micronodular, or infiltrative component. Management of biopsy-proven sBCC should take into account the possible presence of an undiagnosed deeper tumor component with appropriate margin-assessment treatment modalities when clinically indicated.

RESUMEN

BACKGROUND: Telemedicine is an emerging field with numerous applications within medicine. Previous review articles describe its use within plastic surgery and otolaryngology but none, to the authors' knowledge, within dermatologic surgery. OBJECTIVE: To provide a review of the applications of telemedicine within dermatologic surgery. MATERIALS AND METHODS: A PubMed search of articles published on teledermatology was conducted in July 2018. Articles were selected based on their relevance to dermatologic surgery and reviewed for their discussion of the applications of telemedicine in surgical and cosmetic dermatology. RESULTS: The initial search resulted in 156 articles. Eleven ultimately met inclusion criteria: 2 in referral and consultation, 5 in telepathology, 2 in intraoperative uses, and 2 in postprocedural care. CONCLUSION: For preoperative consultation, teledermatology enables the surgeon to plan ahead and increases access to care by reducing the number of clinic visits. Telepathology has the potential to allow intraoperative consultation with a dermatopathologist to achieve accurate tumor clearance without delay. Smartglasses represent a promising technology for greater care coordination and a teaching tool. Postprocedural monitoring via text messaging provides convenient access to expert advice and early detection of postoperative complications. With increasing technologic advancements, telemedicine holds great potential to augment the dermatologic surgeon's daily practice.
