Abstract
Adenoid cystic is a rare histological subtype of basal cell carcinoma. Basal cell carcinoma (BCC), the most common form of skin cancer is a slow-spreading tumor with local malignancy, with a high cure rate and favorable prognosis when is diagnosed in the early stages. Rhinophyma is one of the four subtypes of rosacea and it is histopathologically characterized by sebaceous glands hypertrophy. Disseminated annular granuloma (GAD) is a rare inflammatory dermatosis with uncertain etiopathogenesis, clinically represented by papules with annular or arciform aspect. UV radiations aggravates rosacea and are involved in the etiopathogenesis of BCC and can have a triggering or an aggravating effect on GAD. The association of adenoid cystic BCC with rhinophyma it is rare and more than that, the presence of both in association with GAD is not described in medical literature. We present the case of a 78-year old male patient, with personal history of prolonged exposure to UV radiations, that was admitted to the Dermatology for 4 nodular tumors, located on the face. The skin of the nose and menton with thickened, hypertrophied, irregular, red appearance and dilated pores. Also, on the upper limbs and trunk, the patient had, erythematous papules with arciform and ring shape with hypopigmented centers. We performed surgical excision of the tumors and biopsied an annular lesion. Microscopic examination showed nodular basal cell carcinoma with areas of adenoid cystic carcinoma and actinic degeneration of collagen and gigantocellular granulomatous inflammation. The skin biopsied from the upper limb showed annular granuloma appearance.
