Primary Cutaneous Lymphoma Registry of the Spanish Academy of Dermatology and Venereology (AEDV): Data for the First 5 Years. / Registro de linfomas cutáneos primarios (RELCP) de la AEDV: datos tras 5 años de funcionamiento.

BACKGROUND AND OBJECTIVE: Primary cutaneous lymphomas (PCL) are uncommon. Observations based on the first year of data from the Spanish Registry of Primary Cutaneous Lymphomas (RELCP, in its Spanish abbreviation) of the Spanish Academy of Dermatology and Venereology (AEDV) were published in February 2018. This report covers RELCP data for the first 5 years. PATIENTS AND METHODS: RELCP data were collected prospectively and included diagnosis, treatments, tests, and the current status of patients. We compiled descriptive statistics of the data registered during the first 5 years. RESULTS: Information on 2020 patients treated at 33 Spanish hospitals had been included in the RELCP by December 2021. Fifty-nine percent of the patients were men; the mean age was 62.2 years. The lymphomas were grouped into 4 large diagnostic categories: mycosis fungoides/Sézary syndrome, 1112 patients (55%); primary B-cell cutaneous lymphoma, 547 patients (27.1%); primary CD30+lymphoproliferative disorders, 222 patients (11%), and other T-cell lymphomas, 116 patients (5.8%). Nearly 75% of the tumors were registered in stage I. After treatment, 43.5% achieved complete remission and 27% were stable at the time of writing. Treatments prescribed were topical corticosteroids (1369 [67.8%]), phototherapy (890 patients [44.1%]), surgery (412 patients [20.4%]), and radiotherapy (384 patients [19%]). CONCLUSION: The characteristics of cutaneous lymphomas in Spain are similar to those reported for other series. The large size of the RELCP registry at 5 years has allowed us to give more precise descriptive statistics than in the first year. This registry facilitates the clinical research of the AEDV's lymphoma interest group, which has already published articles based on the RELCP data.

Versatility of Tunneled Island Flaps for the Reconstruction of Facial Defects. / Versatilidad del «colgajo en isla tunelizado¼ para la reconstrucción de defectos faciales.

BACKGROUND AND OBJECTIVE: Tunneled island flaps that transfer skin from a site adjacent to the wound are an effective way to reconstruct defects. These flaps provide good aesthetic and functional results and can be completed during a single surgical session, thus reducing complications. The procedure consists of taking an island of skin about the size of the surgical defect and moving it through a subcutaneous tunnel to cover the wound. We aimed to exemplify the use of these flaps in different regions of the face. MATERIAL AND METHODS: Retrospective descriptive study of 12 cases in which tunneled island flaps were used after removal of malignant tumors in different facial regions. RESULTS: The tumors, all of which were basal cell carcinomas, were removed by means of conventional surgery from 9 patients and Mohs micrographic surgery from 3 patients. Histology demonstrated tumor-free margins after excision in all cases. None of the tumors recurred during a mean follow-up period of 25 months. All complications were minor and transient. There were 3 cases of trapdoor effect and 2 each of postsurgical bleeding, transient superficial flap necrosis, and slight protrusion of the pedicle. The final cosmetic and functional outcome was satisfactory in all cases. CONCLUSIONS: Tunneled island flaps are particularly useful for repairing defects in the center of the face, where several anatomical structures converge. These flaps, which use donor skin that is similar to skin in the receptor site, can be used to close large defects in one-step procedures with only slight alteration of the facial architecture.

Versatilidad del «colgajo en isla tunelizado» para la reconstrucción de defectos faciales / Versatility of Tunneled Island Flaps for the Reconstruction of Facial Defects

Introducción y objetivos: El colgajo en isla tunelizado (CIT) supone una opción eficaz para la reparación de grandes defectos faciales trasponiendo piel desde una unidad anatómica adyacente. La realización del colgajo aporta buenos resultados estéticos y funcionales en un único tiempo quirúrgico, evitando así complicaciones. El procedimiento consiste en labrar una isla de piel de dimensiones similares a las del defecto original, para luego desplazarla a través de un túnel subcutáneo a la región receptora. Nuestro objetivo es ejemplificar su uso en diferentes regiones de la cara. Material y métodos: Estudio descriptivo retrospectivo de 12 casos con reconstrucción mediante CIT tras la extirpación de tumores malignos en distintas áreas faciales. Resultados: Presentamos una serie de 12 casos intervenidos de carcinoma basocelular, 9 mediante cirugía convencional y 3 mediante cirugía de Mohs. El estudio histológico mostró bordes quirúrgicos libres en todas las piezas de resección. El tiempo medio de seguimiento fue de 25 meses sin detectarse recidivas tumorales. Las complicaciones fueron menores y temporales: efecto trampilla en 3 pacientes, hemorragia posquirúrgica en 2, necrosis superficial transitoria del colgajo en 2 y protrusión leve del pedículo en 2 casos. El resultado final cosmético y funcional fue satisfactorio en todos los casos. Conclusiones: Los CIT son especialmente útiles en defectos centrofaciales donde convergen distintas unidades anatómicas. Permiten la reconstrucción en un único tiempo quirúrgico de grandes defectos faciales, aportando piel de características similares a las de la zona receptora y alterando mínimamente la arquitectura facial (AU)

Reconstructing Ear Defects Using the Revolving Door Island Flap: A Case Series. / Reconstrucción de defectos auriculares mediante el «colgajo en isla en puerta giratoria¼. Serie de casos.

BACKGROUND AND OBJECTIVES: Defects of the anterior region of the pinna pose a reconstruction challenge owing to the complex topography and difficult access. We report our experience using the revolving door island flap (RDIF) to reconstruct pinna defects and present the surgical results. MATERIAL AND METHODS: Retrospective descriptive study of patients undergoing ear reconstruction using RDIF at different sites of the anterior region after resection of malignant tumors. RESULTS: Seventeen patients underwent surgery between 2011 and 2019 for squamous cell carcinoma (n=7) and basal cell carcinoma (n=10). Conventional histology showed disease-free surgical margins in all the resected tissue specimens. The mean follow-up period was 40 months. One local recurrence of squamous cell carcinoma was observed, which responded well to radiation therapy; all patients were free of disease at the end of follow-up. Only 3 patients presented minor complications (depression of the flap surface in 1 case and retraction of the ear toward the mastoid process in 2 cases). Subjective rating scales were used to evaluate cosmetic and functional outcomes as assessed by both the dermatologist and the patient. The normal contour of the pinna was conserved in all patients and no patients required additional corrective surgery. CONCLUSIONS: Reconstruction of the pinna using RDIF allowed for satisfactory repair following complete resection of the tumors, while conserving structure and functionality. RDIF has been reported to be a very good option for reconstruction of the pinna. It is a simple technique that makes it possible to repair large defects with minimal risk of necrosis. In our series, the cosmetic results were excellent and recurrence rates were very low. RDIF provided optimal results in repairing lesions in the concha and in other regions, such as the antihelix, triangular fossa, and scapha.

[Dermatomyositis and punctate porokeratotic keratoderma as paraneoplastic syndrome of ovarian carcinoma]. / Dermatomiositis y queratodermia poroqueratósica punctata como síndrome paraneoplásico de un carcinoma ovárico.

Dermatomyositis (DM) is a dermatomyopathy with a broad spectrum of features, defined by Bohan et al as an objective set of clinical and laboratory criteria. Dermatomyositis has been associated with extracutaneous neoplasias, especially with ovarian carcinoma. The term <> comprises a group of diseases with different etiologies characterized by small hyperkeratotic lesions usually scattered in palms and soles. Punctate porokeratotic keratoderma (PPK) is a type of punctate keratoderma mainly defined by its peculiar histological features, including the presence of cornoid lamella similar to the one observed in porokeratosis. Punctate porokeratotic keratoderma has been considered a sporadic disease although some rare paraneoplastic cases have been published. We report for the first time a case of dermatomyositis with typical features of punctate porokeratotic keratoderma, both as paraneoplastic presentation of ovarian carcinoma. Its paraneoplastic nature is clearly demonstrated by the clinical improvement observed following tumor excision.
