ABSTRACT
PURPOSE: Diagnosis of granuloma annulare (GA) is based on the clinical and histopathological findings. However, only sporadic case reports of subcutaneous GA sonography have been published to date. The objective of this study was to evaluate the ultrasonographic patterns of the different clinical variants of GA: localized, generalized, subcutaneous, and perforating. METHODS: In this retrospective observational study, we analyzed and correlated the clinical, histopathological, and sonographic features of 15 patients diagnosed with GA. RESULTS: We included 8 women and 7 men with a mean age of 48.4 years (8-77 years). We found three different sonographic patterns depending on the clinical variant of GA: poorly defined hypoechoic band including the dermis (dermal pattern), irregularly shaped hypoechoic hypodermal lumps (hypodermal pattern), and ill-defined hypoechoic dermal and subcutaneous lesions (mixed pattern). Five cases showed increased blood flow signal on Doppler interrogation. CONCLUSION: Although our findings are broadly consistent with the previous reports of subcutaneous GA, the sonographic features in localized, generalized, and perforating GA have not been previously reported.

Hypertrichosis is a common feature in cutaneous porphyrias, characterized by high accumulation of photoreactive porphyrins. Photothermolysis induced by noncoherent light (755-1200 nm) and energy fluence of 42 J/cm(2) was applied to a patient with hepatoerythropoietic porphyria. Hypertrichosis was almost completely removed after seven sessions without development of skin lesions.

Presentamos el caso de una mujer de 30 años, diagnosticada hacía 2 años de necrobiosis lipoídica por la presencia de lesiones típicas en su pierna izquierda. Consultó en nuestro servicio por la aparición durante el último mes de lesiones nodulares eritematosas muy similares al eritema nodoso en ambos muslos y pierna izquierda. La biopsia cutánea reveló una paniculitis por necrobiosis lipoídica.No se encontró ninguna patología asociada y la respuesta al tratamiento fue favorable (AU)
