Darier disease (DD), also known as follicular keratosis, is a rare autosomal dominant hereditary acantholytic dermatosis caused by a mutation in the ATP2A2 gene. Skin lesions are characterized by persistent confluent papules, preferentially located on the seborrheic areas of the face, chest and back. The hands, feet and nails are also commonly affected. DD has a chronic course with frequent relapses. Their treatment is often difficult and unsatisfactory. We present the case of a 54-year-old male with a history of keratotic papules with a brownish-black color, with a foul-smelling, pruritic and ardent appearance on the back and trunk, since the age of 19, which worsen in the summer. His 27-year-old daughter has a similar picture with her skin lesions started at age of 17 in the region below the breast, back, trunk, feet and hands. After the skin biopsy, the diagnosis was confirmed and acitretin 30 mg/day was instituted. The importance of this case report is to alert health professionals that the diagnosis of DD should be considered in family members of patients, especially those in the first degree, and also in patients with follicular keratolytic dermatoses, being an important differential diagnosis of this group of patients diseases.

Introduction: The involvement of undergraduate student at the beginning of their training in activities based on Primary Health Care (PHC), provides preventive and health promoting actions, and ensures the evaluation of the vulnerability of communities and people. Objectives: To analyze the opinion of students and teachers of two medicine higher education institutions on the relevance of Primary Health Care in this course. METHODS: Students and teachers should be effectively enrolled in order for the study to be conducted, being chosen in a random manner and without interferences on the part of the researchers so that the work was as reliable as possible. A cross-sectional study was conducted with interviews structured in questionnaires about what they thought about PHC. To some students and teachers of the medical course of Valen?a and Grande Rio University (UNIGRANRIO). Before receiving the questionnaire, all interviewed signed a Free and Informed Consent Term, which included the objectives and methodology of the work. Results: 310 students and 51 teachers participated in the study, where 91.43% of the students and 100% of the teachers affirmed that primary care plays a fundamental role in medical education. 94.86% of students and 97.91% of teachers, claimed that the discipline allows a greater contact between undergraduates and community. When questioned about the encouragement that teachers give to students to pursue a career in PHC, 57.87% of the students and 70.83% of the professors said they lacked in such a stimulus. Conclusion: PHC is still very neglected by governmental policies, educational institutions and by the own teachers, that often, turn they attention only to tertiary medicine and, as a consequence, a discouragement of this area occur. Therefore, a higher PHC value is necessary, allowing a more humane look at the patient, valuing their feelings, anguishes and their pathological framework.
