Overview
Micronodular basal cell carcinoma (BCC) is a variant characterized by multiple small, uniform nodules, typically presenting on sun-exposed skin. It often grows slowly and locally infiltrates without metastasizing 1.Diagnosis
Clinical appearance of multiple small, uniform nodules 1.
Histopathological examination confirms nodular architecture with uniform basaloid cells 1.
No specific grading system uniquely for micronodular BCC; generally follows standard BCC staging 1.Management
Surgical excision remains the primary treatment, including Mohs micrographic surgery for precise removal 1.
Curettage and electrodesiccation can be considered for smaller, well-defined lesions 1.
Topical therapies such as imiquimod or 5-fluorouracil are less commonly used but may be considered for superficial lesions 1.Special Populations
No specific guidelines provided in the abstracts regarding management in pregnancy, pediatrics, elderly, or with comorbidities 1.Key Recommendations
Utilize histopathological confirmation for definitive diagnosis of micronodular BCC (Evidence: Expert opinion) 1.
Surgical excision, particularly Mohs surgery, is recommended for optimal local control (Evidence: Expert opinion) 1.
Consider patient-specific factors and lesion characteristics when choosing between surgical and non-surgical treatments (Evidence: Expert opinion) 1.References
