RESUMO
Polymorphous low-grade adenocarcinoma (PLGA) is a rare malignant neoplasm arising almost exclusively in the minor salivary glands. PLGA occurs primarily in the oral cavity, especially in the palate, followed by the oral mucosa and upper lip [1,2]. Conditions involving these locations are often presented at dermatological clinics. Therefore, dermatologists should consider this entity in the differential diagnosis of the oral cavity tumors. We present a case of PLGA in the upper lip.

Granuloma annulare (GA) is a benign inflammatory dermatosis of unknown etiology and chronic course, with different clinical variants. The cases associated with a photodistributed pattern are rare and show a palisading histopathological pattern. We report a case of generalized GA affecting sun-exposed areas with an interstitial pattern. The patient has been followed-up for 6 years, presenting a recurrent course of the disease, with a good response to chloroquine and relapse when no treatment was prescribed.
