Introduction: Surgery is performed more frequently now at days, due to the increasing incidence of melanoma and no-melanoma skin cancer. There are different opinions among dermatologic surgeons between to continue or discontinue antithrombotic therapy prior to the procedure, which increases the risk of thromboembolic events. Prophylaxis with oral antibiotics in the postsurgical period is controversial., Objective: To report the safety of surgery without suspending antithrombotic therapy and without oral antibiotic prophylaxis in dermatology surgery of patients with multiple comorbidities and polypharmacy., Method: We designed a retrospective study. We included a total of 655 patients; 96.6% had at least one comorbidity; 27.7% used aspirin and 4.3% some type of antithrombotic therapy. The most common type of skin tumor was basal cell carcinoma with 69.8., Results: The complication rate was 4.2%; the most was wound dehiscence (1.1%), followed by partial necrosis (0.9%), infection (0.9%), reaction to foreign body (0.6%), complete necrosis (0.3%), bleeding (0.2%) and fistulae (0.2%)., Conclusions: Based on the literature and our experience, dermatologic surgery is safe without suspending antithrombotic therapy or antibiotic prophylaxis in patients with multiple comorbidity., (Copyright: © 2019 Permanyer.)

Subungual melanoma represents 20% of all melanomas in Hispanic population. Here, we report the outcome of 15 patients with in situ subungual melanoma treated with resection of the nail unit with a 5-mm margin without amputation, followed up for 55.93 ± 43.08 months. The most common complications included inclusion cysts and nail spicules. We found no evidence of local or distant recurrences at the last visit of our follow up. Functional outcome was good, with only one patient reporting persistent mild pain. These results support functional, non-amputative surgical management of in situ subungual melanomas., Competing Interests: None

Background: Melanoma is a type of tumor that arises from melanocytes generally located in the dermoepidermal junction. Although melanoma is found in less than 10% of cases, mortality is high representing 75% of deaths attributed to cutaneous cancer. There are four major subtypes: Superficial spreading melanoma, lentigo malignant melanoma, acral lentiginous melanoma and nodular melanoma. Superficial spreading melanoma is the most common type among Caucasians. In a Mexican case series, the nodular type is the most common type reported. The aim of this study was to determine the most common type seen at our medical facility., Methods: We analyzed patient's medical records from March 1981 to December 2006. Demographic data included sex, age, place of residence, occupation, tumor progression, location and clinical description. Histologically we evaluated tumor thickness using the Breslow scale; invasion was measured using the Clark scale. This is a descriptive, cross-sectional and retrospective study., Results: 165 patients were studied, 112 were females and 53 males. The most common location was the lower limb. Acral lentiginous melanoma was the most common subtype., Conclusions: Our findings differ from the other series where they report nodular and superficial spreading melanoma as the most common types. The most common subtypes in our study were acral lentiginous melanoma and lentigo malignant melanoma among females, with a ratio of female-male of 2.1:1.
