Quality of Life in Hidradenitis Suppurativa: validation of the HSQoL-24.

To date, there are no disease-specific instruments in Spanish to assess quality of life of patients with hidradenitis suppurativa. A multicentre study was previously carried out in Spain between 2016 and 2017 to develop the Hidradenitis Suppurativa Quality of Life-24 (HSQoL-24), a disease-specific questionnaire to assess quality of life in patients with hidradenitis suppurativa. The objectiv-es of this study are to revalidate the HSQoL-24 in Spanish with a larger sample of patients, and to present the English version. In this multi-centre study in Spain, patients with hidradenitis suppurativa completed the HSQoL-24, the Dermatology Life Quality Index and the Skindex-29. The Hurley staging system was used to assess the severity of the disease. Validation of the questionnaire was carried out in 130 patients, of whom 75 (57.7%) were women. This study demonstrates adequate values of reliability and validity of the HSQoL-24, confirming the previous test re-test validation and making this questionnaire one of wide clinical validity in terms of results perceiv-ed by patients.

[Annular elastolytic giant cell granuloma: a case report located in non-sun exposed areas]. / Granuloma elastolítico anular de células gigantes: a propósito de un caso localizado en áreas no fotoexpuestas.

Annular elastolytic giant cell granuloma (AEGCG) is an uncommon entity clinically characterized by erythematous annular plaques with atrophic and hypopigmented center, that predominates in sun-exposed zones. The histology shows a granulomatous infiltrate without palisading image, made up of lymphocytes, histiocytes and giant cells, with phagocytosis of elastic fibers, without necrobiosis or mucin deposit. We present the case of a male patient with atypical clinical manifestation on the non-sun exposed skin and AEGCG characteristic histology.

[Granuloma from liquid silicone]. / Granuloma por silicona líquida.

In recent years, the demand for cosmetic interventions to augment soft tissue by injecting different substances has increased, due to their apparent innocuity. However, these procedures are not free from adverse reactions, such as the formation of foreign body granulomas, a phenomenon described in literature with most of the materials used. We report the case of a female patient with inflammatory lesions of the face, whose diagnosis was made after the histopathological study, which revealed a granuloma caused by liquid silicone.
