[Application of Mohs microsurgery in nasal basal cell carcinoma]

Objective: To discuss the application of Mohs microsurgery in nasal and facial basal cell carcinoma (BCC) and analyze the pathological and clinical features. Methods: The clinical data of 127 patients who were diagnosed by pathology as nasal and facial BCC in Qilu Hospital of Shandong University from January 2010 to January 2015 were retrospectively analysed. The value of Mohs microsurgery was discussed and the nasal & facial sites of BCC lesions, clinical and histopathology features were summarized. Results: The proportion of male and female was 1.27︰1 in 127 patients, the ages ranged from 27 to 91 years. The top three inflicted area in nasal and facial was followed by nasal dorsum, nasal root and upper lip.The most frequent clinical type was nodular ulcerative type.The most common pathological type was nodular and pigmented. Routine surgical resection was performed in 62 cases (48.8%) while Mohs micrographic surgery in 38 cases (29.9%). Follow-up duration was 37 months on average. Local recurrence occurred in 5 cases in routine surgical resection group while there was no recurrence in Mohs micrographic surgery group. There was no distant metastasis in all cases. Conclusions: There are few specific clinical manifestation in nasal & facial BCC. Surgical treatment is prefered, especially by Mohs micrographic surgery, because it can strictly control the scope of surgical resection and obtain malformation repairment as well as beauty in nasal and facial region.
