A 58-year-old woman from Mumbai with fair skin and history of chronic sun exposure presents with a 0.8 cm flesh-colored papule with a translucent, pearly appearance and fine telangiectasia on the left temple. No ulceration is noted. Clinical diagnosis of basal cell carcinoma is made, but the patient is unwilling to undergo surgery due to fear of scarring. She has no medical comorbidities. What is the most appropriate next step in management?

Explanation

## Clinical Scenario Analysis The patient has a small, clinically typical BCC (pearly, telangiectatic, non-ulcerated) on the temple. She declines surgery due to cosmetic concerns. Histological confirmation is needed before non-surgical treatment. Curettage and electrodesiccation (C&E) is an effective, minimally invasive alternative when surgery is declined and lesion characteristics permit. ## Management Pathway for Small BCC with Patient Preference ```mermaid flowchart TD A[Small BCC, patient declines surgery]:::outcome --> B{Histology confirmed?}:::decision B -->|No| C[Punch biopsy first]:::action B -->|Yes| D{Lesion characteristics suitable for C&E?}:::decision D -->|Yes: small, superficial, non-infiltrative| E[Curettage and Electrodesiccation]:::action D -->|No: infiltrative, high-risk site| F[Mohs or standard excision]:::action C --> D E --> G[Histology of curetted specimen]:::action G --> H[Follow-up at 3–6 months]:::outcome ``` **Key Point:** Curettage and electrodesiccation (C&E) is a tissue-sparing, effective treatment for small, well-defined, non-infiltrative BCCs. It requires histological confirmation of the diagnosis before proceeding and histological examination of the curetted specimen to ensure complete removal. **High-Yield:** For small BCCs (<1 cm) without high-risk features, C&E has cure rates of 95–98% and leaves minimal scarring compared to surgical excision. It is ideal when patients decline surgery or have cosmetic concerns. ## Why C&E Is Appropriate Here | Criterion | This Case | |-----------|----------| | Size | 0.8 cm (small, ideal for C&E) | | Appearance | Pearly, non-ulcerated (suggests superficial/nodular) | | Location | Temple (non-critical site, acceptable for C&E) | | Histology needed? | Yes, before C&E | | Patient preference | Cosmetic concern (C&E minimizes scarring) | **Clinical Pearl:** C&E works by removing the tumor with a curette (breaking down the lesion along the plane of least resistance) followed by electrodesiccation to coagulate remaining tumor cells and hemostasis. The curetted tissue is sent for histology to confirm complete removal. **Mnemonic:** **CESS** — **C**urettage, **E**lectrodesiccation, **S**mall lesions, **S**uperficial subtypes. This is the ideal scenario for C&E. **Warning:** C&E is NOT appropriate for infiltrative, morpheaform, or recurrent BCCs, or lesions on the eyelid, lip, or nose. Always confirm histology before C&E to rule out high-risk subtypes.
