Overview
Basal cell carcinoma with adnexal differentiation is a variant of basal cell carcinoma that exhibits features of adnexal structures, such as hair follicles or sweat glands, within the tumor. This subtype can present with unique clinical and histopathological characteristics compared to conventional basal cell carcinomas 1.Diagnosis
Histopathological examination is essential for diagnosis, identifying basaloid cells with adnexal differentiation features.
Dermoscopy may aid in clinical suspicion but definitive diagnosis relies on biopsy and histopathology 1.Management
Surgical excision (Mohs micrographic surgery or wide local excision) is typically recommended for definitive treatment.
Recurrence risk management includes close follow-up post-surgery, particularly for larger or more aggressive subtypes 1.Special Populations
No specific guidance provided in the abstracts regarding management in pregnancy, pediatrics, elderly, or patients with comorbidities 1.Key Recommendations
Confirm diagnosis through histopathological examination to identify adnexal differentiation features (Evidence: Expert opinion) 1.
Employ surgical excision methods such as Mohs micrographic surgery for optimal local control (Evidence: Expert opinion) 1.
Implement rigorous postoperative follow-up schedules to monitor for recurrence, especially in complex cases (Evidence: Expert opinion) 1.References
