Introduction: Basal cell carcinoma (BCC) is the most common human cancer. It is an epithelial neoplasm of malignancy limited by slow growth and exceptional ability to metastasize at a distance. It is more frequent in men and in> 40 years, cutaneous phototypes I and II, a prolonged and intense solar exposure, immunosuppression and exposure to ionizing radiation, occur sporadically, although they can be hereditary.

Objective: To present an infrequent case of basal cell carcinoma in unexposed areas Case presentation: Patient 36 years old, male, phototype III, without pathological, medicated, allergic and hereditary antecedents; merchant, not photo-exposed; consultation due to an erythematous lesion in the antero-proximal region of the right arm. Two other lesions are observed, one in the right pectoral region and the other in the right iliac fossa; presumptive diagnosis BCC. Diagnosis: Injury 1: BCC. Lesion 2 and 3: superficial BCC. conventional surgical excision with widening of margins is requested, biopsy reporting free margins, follow-up and prevention measures are indicated.

Conclusions: a case with multiple CBC was presented in non-photoexposed areas without the clinic. Control and follow-up are essential given that they have a high risk of developing melanoma.
