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.

Cold panniculitis.

Cold panniculitis has been described in children and young women following cold exposure. Histopathologically, cold panniculitis shows a mostly lobular panniculitis, which consists of an infiltrate of lymphocytes and histiocytes in the fat lobules. Usually, the dermis shows a superficial and deep perivascular infiltrate mostly composed of lymphocytes, with no vasculitis.

[Annular elastolytic giant cell granuloma: a case report located in non-sun exposed areas].

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].

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.
