Primary squamous cell carcinoma of the pilonidal area.
Two patients with primary squamous cell carcinoma of the pilonidal area are presented. No chronic infection or any other lesion predisposing to malignant transformation was present in either patient. Physicians and surgeons should be aware of the possibility of skin cancer appearing in this area in elderly patients. Biopsy of the lesion, leading to an early diagnosis, may prompt surgical treatment. Complete excision of the lesion is a prerequisite for cure.
