Late Presentation of Xeroderma Pigmentosa With Squamous Cell Carcinoma in Septic Shock: Report of a Rare Case.

Xeroderma pigmentosum (XP) is a rare autosomal recessive pathology affecting nucleotide excision repair against ultraviolet radiation. This leads to an increased predisposition to developing ophthalmological, neurological, and cutaneous conditions with an increased cell turnover. This case reports a late presentation of XP presenting with metastatic squamous cell carcinoma (SCC) and septic shock in an eight-year-old Indian male. Emergency management with IV fluid boluses and broad-spectrum antibiotics showed no improvement in vitals. Urgent surgical debridement and tumor debulking failed to improve laboratory values. Postoperative leukocytosis with fever spikes warranted the need to transfer the patient to a super-specialty oncology unit. Such an adverse presentation is commonly seen in XP-related invasive squamous cell carcinoma. Preventive management requires early identification and a multidisciplinary approach involving dermatologists, ophthalmologists, and surgeons. Late presentations revolve around control of the disease process by sharp debridement and chemotherapy with regular surveillance as the lesions tend to reoccur even after excision and chemotherapy.
