Trichilemmal carcinoma is a rare skin tumor that mainly occurs in the elderly (mean age, 71 years) and is localized in the repeatedly sun-exposed areas, most commonly on the face, scalp, neck, and dorsa of the hands. Its differential diagnosis is made with squamous cell skin cancer, clear-cell porocarcinoma, hidradenocarcinoma, and melanoma. The prognosis of trichilemmal carcinoma is most favorable than that of other skin tumors during radical removal. The paper describes a case of an 80-year-old man with long-standing trichilemmal carcinoma of the skin in the area of the shoulder joint, which is concurrent with squamous cell cancer in another area of the skin.
