ABSTRACT

Abstract Subungual melanoma represents 20% of all melanomas in Hispanic population. Here, we report the outcome of 15 patients with in situ subungual melanoma treated with resection of the nail unit with a 5-mm margin without amputation, followed up for 55.93 ± 43.08 months. The most common complications included inclusion cysts and nail spicules. We found no evidence of local or distant recurrences at the last visit of our follow up. Functional outcome was good, with only one patient reporting persistent mild pain. These results support functional, non-amputative surgical management of in situ subungual melanomas.

ABSTRACT

La papilomatosis reticulada y confluente de Gougerot-Carteaud es una dermatosis poco frecuente que por lo general afecta a individuos jóvenes, especialmente a mujeres de fototipos oscuros. Es asintomática y se presenta como placas pigmentadas con textura papilomatosa que confluyen formando placas reticuladas de mayor tamaño en el cuello y zonas intertriginosas. La causa es desconocida, aunque se ha implicado una queratinización anormal, y en ocasiones se puede asociar a Malassezia sp. Su evolución es crónica con remisiones y exacerbaciones. Por el momento no se dispone de un tratamiento específico. Se presenta un caso tratado de manera efectiva con minociclina que no presentó recidiva tras seis meses de seguimiento.


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.

ABSTRACT

Antecedentes: Los tumores benignos de la piel se definen como el crecimiento autónomo de tejido sin relación con el patrón normal de crecimiento tisular, que persiste después del estímulo que le dio origen. Prácticamente todos los humanos presentan algún tumor benigno, pero la mayoría de las veces no se busca atención ya que no producen molestias. Son escasos los registros sobre la frecuencia de los tumores benignos. El objetivo de este estudio fue informar el número de tumores benignos en el Departamento de Dermatología de nuestro hospital. Material y métodos: Se realizó un estudio retrospectivo en el que se revisaron los registros de histopatología del periodo 2000 a 2006. Se registró año, número de biopsia, sexo, edad, topografía, diagnóstico clínico y diagnóstico histológico. Resultados: Se analizaron 9436 registros de biopsias, de las cuales 3765 fueron tumores benignos, de éstos se eliminaron 595 biopsias por falta de datos, para un total de 3170. Los tumores más frecuentes por grupo histopatológico en forma descendente fueron los tumores melanocíticos, quistes, tumores fibrosos, vasculares, de la epidermis, de tejido adiposo, del pelo, neurales, glandulares, sebáceos, de cartílago y hueso, y de músculo liso. Los tumores más frecuentes en general fueron nevos melanocíticos, quistes epidermoides, queratosis seborreicas, granulomas piógenos, lipomas y dermatofibromas. Conclusiones: Los tumores benignos más frecuentes fueron los melanocíticos constituidos por nevos de unión, intradérmicos y compuestos, y los quistes epidermoides. Esta serie proporciona información de los tumores benignos más comunes en un servicio dermatológico.


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.

ABSTRACT

La enfermedad de Paget mamaria (EP) es una manifestación superficial de enfermedad maligna de la mama. Suele presentarse entre 1 y 3% de todos los cánceres de mama y afecta principalmente mujeres entre los 50 y 60 años de edad. La forma clínica clásica se manifiesta con una placa infiltrada unilateral con eritema, escamas y en etapas avanzadas secreción del pezón o retracción del mismo. Presentamos el caso de una paciente de 51 años quién presentó dermatosis localizada a pezón izquierdo constituida por una placa eritemato-escamosa con costras hemáticas, de ocho meses de evolución, con prurito leve. Se le realizó biopsia y se diagnosticó enfermedad de Paget con carcinoma intraductal.


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.
