Confluent and reticulated Gougerot-Carteaud papillomatosis is an uncommon dermatological condition that affects adolescents, especially young women with dark skin types. It presents itself as asymptomatic pigmented patches with a papillomatous texture that coalesce to form reticular plaques localized in the neck and intertriginous areas. The cause of this disease is unknown, although an abnormal keratinization has been implicated and sometimes has been associated with Malassezia sp. It has a chronic course with remissions and exacerbations. Several therapies have been used unsuccessfully to eradicate it but nowadays there is no specific treatment. We report a case treated efficiently with minocycline without recurrence at 6 months follow-up.

Background: Benign skin neoplasms are defined as autonomous growing tissue unrelated to normal growing of the skin, that persist even after the originating stimulus dissapears. Almost all human beings have a certain number of benign cutaneous neoplasms and many never seek medical attention. There is a dearth of information regarding the frequency of these tumors. The aim of this study was to record the number of benign tumors studied at the Dermatology Department of a medical facility., Material and Methods: A retrospective study analyzed medical records between 2000 and 2006. We included year of admission, number of biopsies, sex, age, tumor location, histological and clinical diagnoses., Results: We analyzed 9,436 biopsies of which 3,765 constituted benign neoplasms; 595 were not included and our total sample was 3,170 tumors. The most frequent tumors according to histopathological diagnoses in descending order were: melanocytic, cutaneous cysts, fibrous tumors, vascular tumors, epidermal tumors, fat tumors, tumors with hair differentiation, neural tumors, glandular tumors, tumors with sebaceous differentiation, cartilage and bone tumors, and smooth muscle tumors. The most common benign tumors were: Melanocytic nevi, epidermal cysts, seborrheic keratoses, pyogenic granulomas, lipomas and dermatofibromas., Conclusions: Melanocytes represented by melanocytic nevi (junctional, intradermic and compound) were the most frequent benign neoplasms, followed by epidermoid cysts. Our results illustrate the most common benign tumors observed in a dermatology department.

Paget's disease of the nipple is a superficial manifestation of an underlying breast malignancy. It has been reported in 1-3% of all breast carcinomas. The peak incidence is between 50 and 60 years. Its clinical presentation includes an unilateral, erythematous, slightly infiltrated scaly plaque and nipple retraction. Sero-sanguineous discharge may be observed. We here report a 51 year old woman who had an eight month history of an eritematous-squamous plaque with hematic scabs in the left nipple, with mild pruritus. A biopsy was taken and the diagnosis confirmed Paget's disease and intraductal breast carcinoma.
