Multiple nonmelanocytic skin cancers in multiple regions

Area of Science:

• Dermatology
• Oncology

Background:

• Nonmelanocytic skin cancer (NMSC), comprising basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), is increasing globally.
• The Republic of Korea has observed a rise in skin cancer incidence, prompting greater scientific focus on NMSC.

Observation:

• A 67-year-old male patient presented with multiple, asynchronous NMSCs across various body sites.
• Initial diagnosis included BCC on the retro-auricle and SCC on the back and face.
• Further examination revealed additional BCC and SCC lesions on the neck, limbs, and head, along with supraglottic and external auditory canal SCC.

Findings:

• The patient was diagnosed with multiple BCC and SCC tumors, including rare locations like the external auditory canal.
• Surgical excision was performed for the primary SCC, with subsequent diagnoses of additional NMSCs.

Implications:

• Patients diagnosed with multiple NMSCs face a heightened risk of developing further skin cancers.
• Regular dermatological surveillance and prompt biopsy of suspicious lesions are crucial for managing patients with multiple NMSC diagnoses.
